Gravity Filters - Sewage Treatment - Reverse Osmosis
Gravity filters are used to remove suspended solids from the service water and are typically downstream of pre-treatment clarifiers. Gravity filters are commonly used when the turbidity and color of the influent are too high for pressure filters (turbidity greater than 50 NTU and color greater than 10 APHA).

Gravity Filters - Water and Wastewater Treatment Solutions
Gravity Filter Overview: Gravity filters are commonly used in applications where liquid-solids separation is required in a variety of different applications for finish water treatment. Gravity filters can incorporate various types of media such as sand, anthracite, greensand and GAC to meet each plant’s water treatment needs.
Upflow filters are frequently used for the pre-treatment of water that is further purified by gravity-type rapid filters or by slow sand filters. In such cases, they can give excellent results and may be well suited for use in small treatment plants. One drawback is that the allowable resistance (head loss) over an upflow filter should
Rapid Sand Filters | Water Treatment | Waste Water
The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing. The mechanism of particle removal also differs. Rapid sand Water filter does not use biological filtration and depends primarily on
The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration.
