During an upgrade of the primary treatment plant, the Metropolitan King County West Point Plant used a new approach to its optical fiber network.Planning and building optical fiber local area networks (LANs) capable of accommodating unknown future capacity and routing requirements have long vexed information systems and information technology managers. The primary cause of this vexation is the high labor cost to construct or modify conventional systems.
In the past year, manufacturers have begun advising consumers that the replacement elements they produce fit other manufacturers housings or pitchers and infer that the hybrid system will perform as well as the original system. This, in NSF's opinion, is not truthful information to the consumer.One of the main purposes of the NSF International Drinking Water Treatment Unit Certification Program is to assure that a drinking water treatment system performs in the marketplace as tested and certified by NSF.
The NSF Certification claims for a water filtration system are null and void when a component is placed in another housing
Many filtration products are available. Asking the correct questions is important in obtaining an optimum product for the desired application.
A new self-cleaning system avoids the premature clogging problems associated with conventional carbon filtration systems, while at the same time providing one micron or submicron filtration.As more Americans are aware of the health risks associated with contaminated water supplies, many citizens are turning to filtered water. One couple, Gerry and Candy Rossettie, who bought a 40-year old, 6,000 sq ft home in Sands Point, New York, wanted to be certain they were getting safe water.
Increased focus on technologies that meet tighter regulatory requirements and increased public pressure has motivated municipalities to take a serious look at microfiltration (MF) membranes as a viable treatment option. This article is intended to familiarize you with the basics of microfiltration and discuss how it compares to conventional alternatives.
Activated carbon is like a radio: everyone knows it works, but few people know exactly how. This article is a brief summary of the sources of carbons, the activation process, the principle of adsorption, and the range of current applications.

Municipal and industrial sectors are looking to new and innovative technologies to meet the demands of modern day consumers' requirements. One such technology is ultrafiltration.
The application of membrane technology
Pilot tests have demonstrated that EHRSF can meet Surface Water Treatment Rule requirements.
No longer are turbidimeters the sole measurement method for water purity levels.
Wastewater is being reclaimed for non-potable uses. The use of this water is alleviating water shormance of the valve.
In addition, buried manually-actuated valves are easier to design and install if the operating valve shaft is horizontal and the gearbox input shaft is oriented toward the ground surface.
One concern with orienting the valve shaft axis horizontally is hydrostatic torque. Hydrostatic torque is a sizable operating torque component on large valves.
