Evaluation of Ceralite-A as an Alternative to Anthracite Filter Media - Case Study
Project Description The Golden Heart WTP located in Fairbanks Alaska is a lime softened, ground water treatment plant with five filter basins, with a combined surface area of 1495 ft2. Typical filter loading rates are in the 2.3 –to 3.1 gpm/ft2. The plant has 16” of 1.0 mm ES anthracite media over 8” of 0.55 mm ES sand which had reached the end of its service life. The ...

Use of bauxite for enhanced removal of bacteria in slow sand filters
Slow sand filtration (SSF) is a well-known process for drinking water treatment and is widely used for the production of biologically stable drinking water and particle removal. The removal process of particles and microorganisms is highly dependent on the buildup of the schmutzdecke at the filter surface. During the ripening period and especially for cold waters, the buildup of the ...

Rich microbial communities inhabit water treatment biofilters and are differentially affected by filter type and sampling depth
Factors affecting microbial diversity (richness) and community structure in biofilter columns were investigated. At a pilot filtration plant, granular activated carbon (GAC), anthracite and sand-based filters were used to treat stormwater from an urban catchment. After 12 weeks operation, sand media filters clogged (hydraulic conductivity declining by 90%) and all filters were destructively ...

Case Study - Wiggins Road Water Purification Works
ASW Engineering, a supplier of water treatment systems in southern Africa, was awarded the contract by Umgeni Water to refurbish 12 twin-cell rapid gravity sand filters. The company’s initial assessment of the problem was that the sealing between the filter nozzle sleeves and the concrete panels, and the sealant used in between the precast slabs of the filter floor, had deteriorated due to ...

Methods for Treating Waste Water of Livestock and Fowl Cultivation
Multi-media filter is a process of using one or several filter media to pass water with higher turbidity through a certain thickness of granular or non-granular material under a certain pressure, thereby effectively removing suspended impurities and clarifying the water. Commonly used Filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment ...

Benefits of Anthracite Carbon Media for Municipal Potable Water Treatment Applications?
Treating water to be of potable water quality requires fairly considerable treatment based on initial water quality. Many tend to jump straight to thinking about more technologically advanced treatments like reverse osmosis and the similar. Of course, there is a bit more involved in drinking water treatment for municipalities. However, anthracite carbon media has been used extensively in ...

Plant upgrades to cloth media filter system - Case Study
Problem A coastal development in eastern North Carolina had aging traveling bridge sand filters that were failing and required extensive mechanical maintenance. The plant was also upgrading from chlorination to UV disinfection, which required consistently low levels of TSS. Solution The facility installed Fluidyne’s Fixed Plate cloth media filter system, meeting requirements for tertiary ...

How industrial water filtration can improve efficiency and save you money
Over the course of the past couple of decades, industrial water filtration has become one of the most important considerations for the average manufacturing facility in North America. These concerns have only increased as water supplies have dwindled and wastewater contamination standards have become more stringent. All of this has led to the need to choose the right industrial water filters and ...

Update on Mt Pleasant WTP Incorporating the MIEX ® DOC Process and How it Compares With a Plant Operating in Enhanced Coagulation Mode
Natural organic matter (NOM) is a major factor impacting on water treatment processes. NOM is a precursor of disinfectant by-products (DBP), a food source for regrowth of micro-organisms and makes downstream processes such as membrane filtration and activated carbon less efficient. Reducing NOM in conventional treatment plants can be achieved by using enhanced coagulation, whereby additional ...

Dependable Pretreatment for UF Membrane Water Treatment System
Lake Forest is a small upper class community along the west shore of Lake Michigan about 35 miles north of downtown Chicago, IL. In 1890 a group of residents started the Lake Forest Water Company on the present site to provide water for the residents of the community. Prior to the spring of 2004, the Lake Forest Water Plant provided traditional water treatment. Coagulating chemicals were added to ...

Home, Sweet Wastewater Building
How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant? A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...
