Unless there is a major hydraulic upset, filter media does not simply fail. Rather, it changes over time in properties like size distribution, roughness, depth, and composition (solids buildup), all of …
Multi-media water filters typically utilize three layers of media for multimedia filtration: anthracite, sand and garnet. These media are often chosen for use in multimedia filters due to the distinct differences in their densities. Anthracite is the lightest filtration media per unit volume, followed by sand, and then garnet.
Taking a representative core sample of your media is a critical first step in evaluating its quality, and it generally involves the following steps: Backwash your filter. Drain the water below the bottom …

These water treatment processes ensure that the water consumers …
In drinking water treatment, filtration plays an important role in the multi-barrier approach employed for the removal of pathogens. The presence of suspended solids and other particulate matter in water …
Part 1 - Introduction to Water Filtration. Filtration is used to separate nonsettleable solids from water and wastewater by passing it through a porous medium. The most common system is filtration through a layered bed of granular media, usually a coarse anthracite coal underlain by a finer sand.
Accumulated deposits on filter media contributes to declining run times, mixing of media, high head pressures, uneven backwashes, mud balls, media growth, media loss, cementing, channeling and other problems – all of which affect the performance, effectiveness and capacity of a filter.
The water to be filtered percolates through a filter bed made up of one or more types of granular materials; the properties of these materials and the bed depth must be adjusted according to the water to be treated and the type of filter selected. Suspended solids are held back in inter-granular spaces, throughout most of the bed's depth.
Water can be re-used if the impurities are removed. For this, we have wastewater treatment plants. One of the best ways is to use dual media filter process. KNOW MORE!
The West Plains Water Treatment Plant monitors system performance with inline turbidity meters before and after the clarification process and after the gravity filter.

Northern Filter Media, Inc. is the leading US manufacturer of filter sand for the potable water, waste-water and pool industries since 1914.
Every surface water treatment plant (WTP) should strive to consistently produce a filtered water turbidity of less than 0.1 NTU from each individual filter. The turbidity goal for clarifier effluent should result in an acceptable gross water …
We carry water filtration media for different types of water treatment applications, such as carbon ( charcoal ), coconut shell granulated activated carbon ( GAC ) and more. The media can be purchased in bulk to replace exhausted media in your existing residential or commercial water filtration systems.
In this paper, the operation of mono and dual media filter beds was examined in a large-scale drinking water treatment plant, located in Thessaloniki (N. Greece).
