The most common process for iron removal from water is to allow water-soluble ferrous iron (FE2+) in water to turn into water-insoluble ferric iron (Fe3+), and then capture FeIII (iron oxide) particles by filtration.
Shower filter dechlorination requires its own unique design approach to meet various health requirements.In less than 10 years, shower filters have grown from a non-industry to a significant niche market. Consumers, at first only concerned with the quality of their drinking water, are now more aware of the importance of removing chlorine, one of nature's most toxic elements, from their shower water, too.
The many considerations in shower filter design
A backwashable depth filter process removes and destroys these microorganisms with great efficiency.
Tertiary Filtration Piloting conducted at two different WWTPs demonstrate improved performance of large anthracite media compared to dual and single sand media filtration.
A thorough discussion of not only water treatment systems, but also the contaminants they remove.
Ground water is the most popular source for water in the United States. Now with growth of proven treatment methods and advances in treatment technologies for contaminated ground water, the future is bright for the ground water industry.
A three-year test of ozone and direct filtration so convinced the Altoona City Authority (ACA) of its merits that the central Pennsylvania water authority is now installing the technology at six new treatment plants and will retrofit another by 1999.

Granular activated carbon (GAC) has been used in the water and wastewater industries to reduce taste, odors and dissolved organic compounds. GAC filter media in potable water treatment plants serve a dual purpose: filtration and adsorption. This article will focus on potential problems with bacteria in the application of GAC at a potable water treatment plant.
GAC filter media is widely used for filtration and absorption, but potential problems with bacteria in GAC's application need to be explored
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
