The City of Salem’s Utilities Commission settled a plan for chlorine by-product level reduction in drinking water, through water testing and treatment. The operation is slated to use a Parker THM (Trihalomethanes) Analyzer worth an estimate of $32,500 and $3,000 for chemicals and miscellaneous items, respectively. This THM Analyzer is expected to test the treated water for presence of disinfectant by-products and allows for chemical adjustments, while complying with state rules.
The Environmental Protection Agency (EPA) recentlyupdated its setfederal policy concerning surface water treatment for public safety. Formally referred to as the Surface Water Treatment Rule, this newly amended federal decree states that water systems should be filtered and purified straight from surface water sources to prevent waterborne diseases caused by microbes. Legionella and Giardia lambliaare present at varying concentrations in most surface waters.
A team of sustainability and innovation specialists recently published a research study entitled “The Journal of Membrane Science” that discussed in detail the potential of abrasion-resistant polyvinylidene fluoride (PVDF) or nanoclay hollow fibers composite membranes containing commercial nanoparticles to be used in various water treatment applications.
A professor of geochemistry and water quality at the Duke University’s Nicholas School of the Environment recently conducted a study that discussed the potential of acid mine drainage to help reduce radioactivity in fracking wastewater.Fracking or hydraulic fracturingis a technique used by petroleum engineers to extract industrial gas and natural oil from shale rock formations.
Idaho National Laboratory (INL) has developed a new technology that could turn fracking wastewater into potable water. Switchable Polarity Solvent Forward Osmosis (SPS FO) aims to alleviate criticism directed towards hydraulic fracturing- a process that produces 3 to 5 million gallons of concentrated wastewater per drill site.
Development of Janus Nanotubes Increases Potential of New Drug and Water Purification Discoveries and InnovationsWritten by Nicholas Papp
Scientists from the University of Warwick and the University of Sidney recently created the Janus Nanotubes through a process of molecular engineering. This innovation can be used to improve a number of processes and systems, such as the development of new drug systems and water purification advancements. Janus Nanotubes’ two main building blocks are cyclic peptides and the highly versatile material, polymer.
Proper utilization of basic information including water quantity, quality, grade and maintenance is the key for optimal reverse osmosis water purification.
Choosing the right water purification system requires laboratory staff and technicians to consider key issues and industry standards. This knowledge serves as a guide in specifying the latest technologies that may aid in improving laboratory water quality depending on the lab’s requirements.
Ultrapure water technology suppliers expect revenues to reach $4.4B in 2014 according to the McIlvaine Company study issued in their publication, “Ultrapure Water World Markets”. The study also revealed that the power industry remains the largest purchaser of ultrapure water equipment.
The Arcada University of Applied Sciences in Helsinki successfully produces nano-sized pores to cut water production costs. Dr. Mikael Paronen, head of the Department of Energy and Materials Technology, claims that this nano pore technology could be globally significant in making clean water available.
March 22 is World Water Day, and this year the celebration focuses on The Year of International Water Cooperation. UN Water reminds us that rivers often flow through multiple countries, and actions by one country or community can affect their neighbors’ ability to meet their water needs. Consuming too much water, or polluting a shared body of water, can make it hard for others to have enough for drinking, hygiene, agriculture, ecosystem health, and other needs.
Water Technology magazine reports that many customers in both the laboratory and industrial sectors are now looking for sustainable options when it comes to water treatment, including reverse osmosis (RO) systems.Professionals cannot dispute RO’s effectiveness, but they are also aware of the technology’s drawbacks, such as high energy requirements, and product water to wastewater ratio.
Business consulting firm Frost & Sullivan held a web conference last March 13 discussing the increasing penetration of membrane technologies, including reverse osmosis (RO), microfiltration, ultrafiltration and nanofiltration. Research analyst Paulina Szyplinska lead the event and explained how membrane filtration systems can address global water challenges by ensuring high quality supply to the laboratory, industrial and even the global population.
Market research firm McIlvaine Company concludes in a recent study that various industries all over the world will contribute to generating over $468 million in ultrapure water systems and instruments sales for 2013.
There will be a growth in revenue for ultrapure water purification systems, instruments and even controls this year as electronics, power, scientific and laboratory industries continually demand for ultrapure water.
The Turnkey Landfill of Rochester under the city's Waste Management will be using a reverse osmosis (RO) system to address the wastewater treatment plant problems, including the low transmissivity levels in the water as well as the significant amount of nitrogen passing through the city's plant. The upgrades are expected to be completed summer of 2013.
A reverse osmosis (RO) system will be implemented for the treatment of leachate — the precipitation and melted snow that filters through the landfill waste and collects on the bottom. After the leachate is pretreated at Waste Management, it travels to the city's wastewater treatment plant, where it's treated and then discharged into the Cocheco River. Aqua Solutions offer various options in RO pretreatment to meet both laboratory and industrial requirements similar to this.
Aqua Solutions recently released the Programmable Remote Dispenser 2700PRD for the easy and quick delivery of measured volume of deionized water. The dispenser is designed for use on new and existing Aqua Solutions water purification systems, and can be customized for operation on other systems.
The Programmable Remote Dispenser delivers precise, measured volume of deionized water at the press of a button. After selecting a volume, the operator simply pushes a button to deliver the required amount.
The 2700PRD dispenser is manufactured for repeat operation as its easy-to-select volume is retained in the equipment's non-volatile memory. It also offers versatility with its volume range of 0.1 liters to 100 liters, which can be selected in increments of 0.01 liters. The dispenser will accurately measure volumes over a flow rate range of 0.6 Liters/minute to 5 Liters/minute.
