Filtration is one of the core processes in water treatment. The term refers to the removal, mainly by physical action, of suspended solids as the suspension flows through a bed packed by granular media.

 — UFRV's – Unit Filter Run Volume is the total amount of water through each square foot of filter media between backwashes. Combined Filter effluent (CFE) and Individual Filter Effluent (IFE) Nephelometric turbidity unit (ntu)

Filtration is the fundamental system in a water treatment process that removes suspended solids, including microorganisms such as Cryptosporidium oocysts and Giardia cysts.

Filtration is an extremely important component of any conventional water plant. The role of a filter is even more critical for direct-filtration facilities. In order to ensure optimal performance, many experts recommend replacing the sand and anthracite in a typical dual media filter every 10 to 20 years.

A media filter is a type of water filtration equipment that is used to trap and remove all the suspended solids such as slit, clay, grit, organic matter, and algae from the raw water. The media filters can consist of one or more layers.

 — Although sand is one of the major filter media, alternative media have been developed and used in recent years. In this review, the performance of alternative media is compared with traditional...

Backwash with air scour then water. Fill filter with water, add hypochlorite to disinfect, contact time. Drain filter to 1-ft above media, then air scour to agitate.

 — A recent work examined the effect of applying dual media configured filtration to the reduction in phenols in a conventional drinking water treatment plant, using two types of GAC (vegetable and mineral) and three GAC/Sand configurations (1/0; 0/1; 0.5/0.5).

ABC WATER TREATMENT PLANT ANTHRACITE SAND D10, effective size, mm 0.85 0.45 D60 /D 10, uniformity coefficient 1.40 1.50 D90 calculated, cm 0.15 0.09 ... • D90 /D 10 ratios for dual media filters • 3 for anthracite / sand media • 5 for GAC / sand media • Low D 90 /D 10 ratio -media layering • High D 90 /D 10 ratio -mixed media. 52

 — Adsorptive water treatment technologies involve passing contaminated water through a media bed. The contaminants in the water adsorb to empty pore spaces on the surface of the adsorptive media as the water passes through.
