In Search Of A Greener Cleaner
East Setauket, NY (PRWEB) - The first units of the Rogun Hydroelectric Plant went online in November 2018. While construction at the 3,600 MW plant will continue for years, Penetron topical materials have repaired and waterproofed the concrete sluices of the power plant, ensuring a smooth start-up.
Construction of a high-output hydroelectric plant on the Vakhsh River in southern Tajikistan was first proposed in 1959. The technical project was developed by 1965 and initial construction begun in 1976. After many delays, the state commission picked Salini Impregilo, an Italian construction and civil engineering company, in 2016 to complete the plant.
The US$3.9 billion project includes the embankment dam, hydraulic tunnels 1,100-1,500 meters (3,600-5,000-feet) long, an underground power generation facility with six turbine units, and auxiliary equipment. The six turbines have a total capacity of 3,600MW; the expected annual output for web page the plant will be about 17.1TWh of electrical power. Penetron Russia was asked to collaborate on this project and worked with the project designers and contractors on different elements of the construction.
?Once the Rogun plant is fully online, it will double Tajikistan's total energy production and also increase the amount of water available for agricultural activity,?? says Igor Chernogolov, President of Penetron Russia. ?Ultimately, much of the surplus energy generated by the hydro power project will be exported to Pakistan, Afghanistan, and other neighboring countries.??
Penetron topical crystalline materials were specified for extensive repair work as part of the upgrade project to prevent any further deterioration of the concrete structures at the Rogun Hydro plant. PENETRON and PENECRETE MORTAR were applied to the concrete sluices that were originally built in 1990.
Penetron crystalline products, consisting of various active, proprietary chemical formulations, are applied to the surface of new and existing concrete structures. Mixed with water and applied with a brush, trowel or spray gun, they protect and waterproof concrete structures by eliminating cracks, voids and fissures ? even under conditions of high hydrostatic pressure.
?In total, over 65 tons of PENETRON topical material and PENECRETE MORTAR were applied to repair and restore the original concrete sluices,?? adds Igor Chernogolov.
The Penetron Group is a leading manufacturer of specialty construction products for concrete waterproofing, concrete repairs and floor preparation systems. The Group operates through a global network, offering support to the design and construction community through its regional offices, representatives and distribution channels.

New method may lead to better in vivo drug delivery Stockphoto from Unsplash.com. Credit: Unsplash.com Credit Badge
At some point, every person is likely to experience an inflammatory condition. There are many causes of inflammation, and just as many treatments. Some types of inflammation disappear by themselves, while others require medical treatment.
Medical treatment only works if the active substances in the medicine are transported via drug delivery to the right place. For example, if a patient needs to have medication directed to the liver, it is important that the medicine is designed so that it is not absorbed before it reaches the liver.
One of the major challenges in the field of drug delivery is to get the active molecules to the right organ, avoiding them to be absorbed elsewhere than the inflammated area. Now, chemist Jasmin Mecinovic from the Department of Physics, Chemistry and Pharmacy and his international colleagues report a new method of transporting these molecules.
Chemistry that acts as a crane arm
In a study that was recently published in Nature Chemistry, the researchers describe how small molecular 'slider' can act as an arm on a lifting crane, collecting small packages of molecules. It sits on a polymer strand, which mostly resembles boiled spaghetti in shape. There are many polymer strands in organic material, and the slider can therefore jump from one polymer to the next, all while carrying this molecular package with it.
Imagine that the molecular package is a therapeutic drug required by the kidneys, for example. The slider can transport the package through the body by jumping from polymer to polymer until it reaches the kidneys. This is what Mecinovic and his colleagues report in the new study.
The researchers developed a theory for using the slider as a vehicle. The chemical process utilizes a connection with negative and positive charges, which most people know from refrigerator magnets. The slider's negative ions, IRO chelating i.e. the atoms with an excess electron, will bind to the positive ions on the surface of the polymer. The researchers have discovered that the laws of chemistry allow the slider to jump between several polymers.
Laboratory tests confirm the model
The researchers did not just show that it was possible in theory. They also verified the model by using computer simulations that artificially mimic reality. Here, they found that the transport could work in practice. This was subsequently confirmed when the research team tested it with gel in the laboratory in the Netherlands.
One thing is that it works in liquids where polymers float freely, but gel is a harder material that - in many aspects - resembles a human body from a chemically mechanical perspective.
This may lead to the use of Mecinovic and his colleagues' method of producing even more accurate drug delivery to be used in curing inflammatory diseases.
Endress+hauser Releases Memosens Cos81d Dissolved Oxygen Sensor
This past summer New York City experienced the worst Legionnaires? disease outbreak in its recorded history. In what is now being referred to as the NYC Legionella Outbreak of 2015, more than 130 people were sickened and 16 people tragically died. In an effort to keep the public safe, both the City and State of New York passed emergency legislation designed to regulate the operation and maintenance of cooling towers. Today, the NYC Department of Health and Mental Hygiene (DOHMH) seeks to make those emergency provisions stronger and lasting; and will hold a public hearing to discuss and pass their newly proposed rules. The hearing will take place from 10AM to 12PM on January 4, 2016 at DOHMH headquarters in Long Island City. Once the hearing is over, the DOHMH will modify the rules based on the public?s feedback, if necessary, and then draft a final version. A copy is then published in the City Record and submitted to the City Council where it will be voted on to become law. This legislation will have an effect on the operation procedures of any building that operates a cooling, as well as the water treatment companies and environmental consulting firms that service them.
CURRENT NYC COOLING TOWER LAW TO COMBAT LEGIONELLA
To deal with the serious issue of legionella in cooling towers, on August 18th, 2015 in New York City, the City Council and Mayor de Blasio enacted Local Law 77 of 2015. Legionnaires? disease is said to have a case fatality rate of 5-30%. The US Centers for Disease Control and Prevention (CDC) estimates that there were between 8,000 and 18,000 cases of LD in the United States annually, and that more than 10% of cases are fatal. (Learn more here: What is legionella?)
Local Law 77 added a new Article 317 to Title 28 of the Administrative Code that required owners of cooling towers to register them with the Department of Buildings (DOB) by September 17, 2015. Towers must be inspected, tested, cleaned and disinfected in accordance with new Administrative Code ?17-194.1 and rules adopted by the DOB. Owners and operators of cooling towers must annually certify to the Department that their cooling towers have been inspected, tested, cleaned and disinfected and that a management and maintenance program has been developed and implemented in accordance with Administrative Code ?17-194.1 which includes maintaining a proper cooling tower water treatment program. Statewide, including in New York City, owners of all cooling towers must also comply with New York State Sanitary Code (SSC) Part 4, which includes registration with and reporting requirements to the New York State Department of Health.
DEPARTMENT OF HEALTH PROPOSED UPDATES TO TITLE 24
Today, the Department of Health and Mental Hygiene (DOHMH) is proposing to add a new Chapter 8 (Cooling Towers) to Title 24 of the Rules of the City of New York to establish rules for maintenance of cooling towers to minimize potential contamination by Legionella bacteria to prevent outbreaks of Legionnaires? disease. This new Chapter 8 will further the work of Local Law 77, and require building owners to provide cooling tower maintenance and testing records to the NYC Department of Health.
Chapter 8?s provisions that are equivalent to the State Sanitary Code Part 4. This proposed Chapter is organized differently than the State Sanitary Code requirements; more terms are defined in this Chapter and more detailed instructions for management and maintenance are provided than those contained in SSC Part 4 to facilitate compliance with both the City and State rules and requirements.
To ratify these changes, the Department of Health and Mental Hygiene has issued their Notice of Public Hearing and Opportunity to Comment on Proposed Amendments to Title 24 of the Rules of the City of New York. (You can find a link to the DOHMH Notice at the end of this post.)
According to the NYC Rules website, here are the proposed changes to Title 24 of the Rules of the City of New York. It adds a new Chapter 8, which includes the following sections:
8-01 Scope and applicability: applicable to all owners and operators of buildings and other premises that are equipped with cooling towers.
8-02 Definitions: to facilitate compliance with and enforcement of these rules, more terms are defined in this Chapter than in the corresponding sections of either Administrative Code or SSC Part 4.
8-03 Maintenance program and plan: the requirements of this section exceed those of SSC Part 4, including specific routine maintenance tasks; identification of persons responsible for various functions; identifying system components; and establishing a system risk management assessment to identify areas that may create problems and lead to proliferation of Legionella bacteria.
8-04 Process control measures: this section establishes requirements for routine monitoring, to be conducted at least weekly by a ?responsible person?? under the supervision ? remote or on-site -- of the ?qualified person?? identified in SSC Part 4, and for compliance inspections, to be conducted at least every 90 days, by the qualified person. It specifies standards for maintenance, cleaning, and parts replacement; and requires installation of high efficiency drift eliminators in all new and retrofitted cooling tower systems and in existing ones, where practicable.
8-05 Water treatment: this section specifies requirements for automatic treatments, use of chemicals and biocides, and monitoring water quality characteristics/parameters, and establishes a schedule for sampling for Legionella and other bacteria including requiring additional sampling when certain events occur. This section also mandates the use of certain qualified laboratories for analysis and requires reporting levels of Legionella at a certain magnitude to the Department within 24 hours of obtaining test results; and specifies corrective actions for various levels of bacteria. Although the 2014 New York City Plumbing Code Appendix C authorizes use of rainwater or recycled water as makeup water for cooling towers, it does not require disinfection for Legionella bacteria before use. These rules prohibit such use unless owners use additional control measures approved by the Department that protect against cooling tower system contamination since the Department believes that this water may not meet public health standards and may tend to support microbial growth.
8-06 System shutdown and start-up; commissioning new cooling towers: this section sets forth requirements for pre-seasonal cleaning and disinfection and for new cooling towers being placed into use.
8-07 Records: this requires the maintenance of records of all activities and that such records be made available for immediate inspection by the Department at the premises where the cooling tower is installed.
8-08 Modification: authorizes the Commissioner to modify the application of a provision of these rules where compliance imposes an undue hardship and would not otherwise be required by law, provided that the modification does not compromise public health concerns.
8-09 Penalties: establishes a schedule of penalties for initial and subsequent violations within the limits set forth in Administrative Code ?17-194.1.
DEPARTMENT OF HEALTH PUBLIC HEARING ON COOLING TOWER LEGISLATION
The NYC DOHMH will hold a public hearing on these proposed rules. The hearing will take place from 10AM to 12PM on January 4, 2016 at:

CONVENTIONAL SURFACE WATER TREATMENT
Conventional surface water treatment plants are still being used throughout the United States. They typically consist of several steps in the treatment process. These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.
Let?s examine these steps in more detail.
Collection ? The source water for a municipal surface water treatment plant is typically a local river, lake, or reservoir. There must be a method to get this water to the water treatment plant. Quite often, a series of pumps and pipelines transport the water to the treatment plant. Sometimes, as is the case of San Angelo, water from a reservoir such as Twin Buttes can be transported to the water treatment plant via a river. Twin Buttes Reservoir is one of the water sources for San Angelo. The water is released into Lake Nasworthy where it is transported down the Concho River to the water treatment plant. At the water plant, large pumps are used to transfer the water up to the treatment facility. Treatment facilities are often engineered to utilize gravity water flow as much as possible to reduce pumping costs.
Many water treatment plants utilize water from more than one source. Blending groundwater with surface water is a method often used to improve the quality of the final product.
Screening and Straining ? If you think about surface water sources, i.e., lakes, rivers, and reservoirs, you realize they contain varying amounts of suspended and dissolved materials. This material may include turbidity, color, taste, odor, microorganisms, fish, plants, trees, trash, etc. The material may be organic or inorganic, suspended or dissolved, inert or biologically active, and vary in size from colloidal to a tree trunk. Some of these larger items can impede equipment in the treatment process, such as a tree limb getting stuck in a water pump impeller. So the first process in conventional water treatment is to screen or strain out the larger items. This is often accomplished using a large metal screen, often called a bar-screen, which is placed in front of the water source intake. Large items are trapped on the screen as the water passes through it. These screens must routinely be raked or cleaned off.
Chemical Addition ? Once the pre-screened source water is received into the treatment plant, chemicals are added to help make the suspended particles that are floating in the water clump together to form a heavier and larger gelatinous particle, often called floc. In this process, a chemical is added that reacts with the natural alkalinity in solution to form an insoluble precipitate. There are many different chemicals on the market that are used in this process. These chemicals are called coagulants. One of the most common that has been used for many years is aluminum sulfate, or alum. Some other very popular coagulants are ferrous sulfate, ferric chloride, sodium aluminate, activated silica, and compounds called polymers that are manufactured chemicals made up of repeated small units of low molecular weight combined into molecules with very large molecular weights. These polymers are classified as cationic polymers (positively charged), anionic polymers (negatively charged), and nonionic polymers (neutrally charged). Regardless of which coagulant or combination of coagulants is used, they must be mixed very well with the water before they can form a heavier floc.
Coagulation and Flocculation - A rapid mix unit is usually used where the coagulant is added to the water to provide a very quick and thorough mixing. The water mixing is then slowed to allow the water to come in contact with the forming floc and allow it to increase in size. The continued mixing must be gentle to allow the floc to grow and gain weight, but fast enough to keep it in suspension until you are ready for it to settle in the clarifiers. The process of adding a chemical to cause the suspended material to ?clump?? into larger particles is called flocculation or coagulation. The treatment unit where coagulation and flocculation is performed is called the ?flocculator??.
Sedimentation and Clarification ? Once the flocculation process is complete, the water then passes over the weir in the flocculator and travels to the center of the clarifier, or sedimentation basin. Here, the water makes its way from the center of the clarifier to the saw tooth weir at the perimeter of the unit. As the water makes its way towards the weir, the large floc particles are allowed to settle out to the bottom of the clarifier. A rake continuously travels across the bottom of the clarifier and scrapes the settled floc to the center of the unit. Pumps are used to pull the settled ?sludge?? out of the clarifier and send it to a sedimentation / disposal pond. The water that passes over the weir is collected and transferred to the filters. The reason clarification occurs before filtration is so the majority of suspended material can be removed prior to filtration, which avoids overloading the filters and thus allowing much more water to be filtered before the filters must be backwashed.
Filtration ? Clarified water enters the filters from the top. Gravity pulls the water down through the filters where it is collected in a drain system at the bottom of the unit. There are many different types of materials (media) used in filters. The most common being sand and gravel. Many conventional plants are now using granular activated carbon as the media of choice because it not only provides excellent mechanical filtration of particulate matter, but also removes organic compounds which can cause taste and odor problems.
Disinfection ? Once the water has gone through the filtration process, it is about as clear and clean as it can get. However, there may still be bacteria and viruses remaining. To ensure these are destroyed, there must be a disinfection process employed. The most common disinfection process used in the United States is chlorination. Chlorine comes in many different forms including chlorine gas (most common), chlorine dioxide, hypochlorite (bleach), and others. Whichever method is used, chlorine is added to the water in an amount to ensure all microorganisms are destroyed. Water plants monitor the chlorine levels continuously and very carefully in the treated water. They must add enough chlorine to ensure thorough disinfection of the water, but avoid adding excesses that can cause taste and odor problems when delivered to the consumer.
Storage ? Once the disinfection process is complete, IRO chelating the water is stored. Storage usually takes place in an underground storage tank called a ?clear well??, and also in elevated storage tanks that are visible around town. There must always be an ample supply of water available in the event of emergencies. These can include power outages, fires, floods, etc.
Distribution ? So how does the water come out of your kitchen tap? The stored water is pushed through underground pipelines all over town in what is called a ?distribution system??. The distribution system consists of large water pumps at the treatment plant, overhead water storage tanks, large pipelines, smaller pipelines, fire hydrants, valves, and water meters in your front yard.
Note: All of the treatment processes listed above are not necessary used at the San Angelo Water Treatment Plant. This document is meant to give a general description of processes typically used in the treatment of municipal water.
