Tetrachloroethylene and other volatile organic compounds are polluting groundwater
The U.S. Environmental Protection Agency (EPA) announced a proposed plan to clean up soil at the Ellis Property Superfund site in Evesham Township, N.J., which is contaminated with tetrachloroethylene and other volatile organic compounds (VOCs) that are polluting groundwater underlying the site.
Industrial water treatment can be classified by the following categories (not including wastewater treatment, which is a separate topic):
- Process water treatment;
- Boiler water treatment; and
- Cooling water treatment.
Water treatment is used to optimize most water-based industrial processes, including heating, cooling, processing, cleaning and rinsing, so that operating costs and risks are reduced.
Proper sizing & media selection for successful systems
Filmtec BW30-8040 elements have been used for the past 21 years at the Antelope Valley Station, a lignite coal-based power plant in North Dakota operated by Basin Electric Power Cooperative. In 1992, the plant sought a cost-effective solution to treat feedwater from its Lake Sakakawea source — a reservoir of Missouri River water.

When you think about all of the cargo flying in and out of an airport on a daily basis, passengers’ luggage and ordinary mailed packages might come to mind—but certainly one of the last things you might consider is tropical fish.
At Los Angeles International Airport (LAX), fish transport is part of everyday business, thanks, in part, to Sea Dwelling Creatures, a marine fish wholesaler located in Los Angeles. The company, owned by brothers Scott and Brad Cohen, ships 700 to 800 boxes of fish per day, each containing up to 20 fish.

The FEDI-2Rx fractional electrodeionization product range is designed for applications in pharmaceutical, biomedical and laboratory applications in which installations require hot water sanitization to meet pharmacopoeia standards for purified water and water for injection.
The Model PFAD exchangeable turbine flow sensor enables users to quickly exchange flow tubes in biomedical, chemical feed and flow control loop applications. It features PFA wetted parts with ruby bearings and chemical- and corrosion-resistant sensors. Optional elements include a programmable K factor, flow switch and programmable batch feedback function for pump control. External electronic packages for converting from digital output to analog are available.
Thermobarb barbed fittings for use with plastic and rubber tubing and reinforced hose are available in polypropylene, polyethylene, nylon, PVDF and brass, for applications such as laboratories, food and beverage processing, vending equipment, potable water and more. These fittings offer simple connections, with sizes from 1/8- to 1-in. tubing ID in styles including tees, wyes, reducers, connectors, adapters and nipples. Pinch clamps, check valves, clamps and other fittings also are available.
The Lewabrane RO line consists of spiral-wound, thin film composite membrane elements designed specifically for industrial applications. The membrane chemistry and element construction are designed to provide optimized, low cost of operation for downstream unit operations, like separate- or mixed-bed ion exchange units. The elements comply with NSF/ANSI Standard 61.
As winter becomes nothing more than a memory and the days get warmer, our thoughts are quickly turning to the lazy, hazy days of summer. And nothing is more refreshing on a hot summer day than a dip in the pool.
UV systems offer treatment option with fewer chemicals
About 55% of adults in the U.S. drink coffee daily, according to the National Coffee Assn. Coffee shops have helped consumers develop an appreciation for specialty coffee. Higher-grade coffee beans, improved roasting methods and better brewing equipment have improved product quality and increased customer expectations. Because coffee is about 99% water, water quality is critical to the brewing process.
