NuPure-Direct UV laboratory water systems are designed to produce RO and type-1 water qualities. The systems produce ultrapure water for preparation of high-performance liquid chromatography (HPLC) mobile phase; reagent blank solution as sample diluents for GC, HPLC, AA, ICP-MS and other analytical techniques; buffer and culture media for mammalian cell culture; molecular biology reagents; and more.
Chem-Feed engineered skid systems are efficient and lightweight. Units for single- or dual-metering pump configurations are constructed of 6061-T6 powder-coated welded aluminum. Additional features include a flow indicator; self-filling calibration cylinder; Plast-O-Matic ball valves, pressure relief valve and gauge guards; metal-free check; removable drip containment; and wall-mountable skids. Systems have a small footprint and feature a pressure relief valve, 5- to 100-psi setting range and 125-psi maximum system pressure.
The Wilkins ZW204 non-modulating float valve maintains accurate fluid levels in tanks or reservoirs. It is equipped for threaded connections from 1.25 to 3 in., and flanged for grooved ends from 1.25 to 10 in. The Wilkins ZW205FP Fire Protection Pilot-Operated pressure relief valve is equipped for threaded connections from 2 to 3 in., and flanged for grooved ends from 2 to 10 in. The Wilkins P4000A Fire Protection thermal expansion relief valve relieves excess pressure buildup.
CH2M Hill treated 1.4 billion gal of groundwater between October 2012 and June 2013
U.S. Department of Energy (DOE) contractor CH2M HILL Plateau Remediation Co. (CH2M HILL) has exceeded this year’s goal for treating 1.4 billion gal of contaminated groundwater at the Hanford Site in Washington state.
According to a Zenith Intl. report, there has been a major shift in the types of machine used
The western Europe water cooler market, which scarcely existed 25 years ago, climbed to a record 2.78 million units installed at the end of 2012, according to a new report from the sector’s specialist consultancy, Zenith Intl.
New facility will be used for engineering, manufacturing and assembly of water treatment solutions
Illinois Gov. Pat Quinn will join a host of dignitaries from state, federal and local government at the formal opening of Culligan Intl.’s new expanded facility in Libertyville, Ill. The expansion features 217,000 sq ft of manufacturing, assembly, warehousing and office space. Approximately 75,000 sq ft is dedicated to manufacturing — triple the space of its previous facility.
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.
RO membranes provide power plant with cost-effective, environmentally friendly treatment
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.
