Chapter Sand Filters Page 3 Design Criteria Basic Requirements As previously stated, there are two types of sand filters. The following illustrations depict the basic components of both types of sand filters and the various zones through which stormwater travels.

Filter Media Volume Calculator. These calculators will determine the weight and volume of a chosen filter media for both cylindrical or rectangular, such as anthracite or Greensand Plus™, based upon your specific dimensions. Enter length, width, and depth values to calculate the volume and weight of the filter media you will need to order.
Below is a link to an API oil water separator sizing spreadsheet developed by HydroFlo Technologies. By inputting the major design criteria, you can solve for the separation chambers width to length to depth ratios. The spreadsheet operates on Microsoft Excel 2003 or later. API sizing calculations. Below is a sample shot of the spreadsheet.
How to Size a Pool Filter and Pump System. Your swimming pool is a big investment, so you want it to run smoothly for years to come. Choosing the correct size pump and filter system will ensure that your water is wellfiltered and that the pipes won't be damaged by excessive water pressure.
− Filter separator NOTE The design of gas/liquid/liquid threephase separators is excluded from the scope of this DEP; for this subject, DEP should be consulted. Users of this DEP should first consult Section 2 ("Selection Criteria for Gas/Liquid Separators") to familiarise themselves with the general design philosophy and the
The contaminants are metabolised by the bacteria, fungi and protozoa. The water produced from an exemplary slow sand filter is of excellent quality with 9099% bacterial cell count reduction. Slow sand filters slowly lose their performance as the biofilm thickens and thereby reduces the rate of flow through the filter.
September 1999 Wastewater Technology Fact Sheet Intermittent Sand Filters DESCRIPTION Intermittent Sand Filters (ISFs) have 24inch deep filter beds of carefully graded media. Sand is a commonly used medium, but anthracite, mineral tailings, bottom ash, etc., have also been used. The surface of the bed is intermittently dosed with

The pressure sand filter is highly suitable for the systems with high sediment, silt, sand, and turbidity. Our innovative design ensures the maximum utilization of the surface area, lesser pressure drop across the pressure bed and effective elimination of the impurities.
a. All plants had a capacity of Sand filtering area, 8and size, sand depth and method of applying coagulant were fixed by the company supplying the equipment. b. Most of the devices added coagulant to the water as it entered the filter box above the sand. Ho separate mixing and settling was practiced prior to filtration.
Finer filter sand means shallower areas for the removal of suspended solids. The best media size depends on the suspended solids' characteristics, as well as the effluent quality requirements. In general, rapid sand filters use sand with an effective size of to mm and a maximum uniformity coefficient of

filtration. Most rapid sand filters contain 2430 inches of sand, but some newer filters are deeper. The sand used is generally to mm in diameter. This is larger than the sand used in slow rate filtration. The coarser sand in the rapid filters has larger voids that do not fill as easily.

Facilities Design effectivesize coal is the most efficient filter media size from the viewpoint offi efficiency and head loss development during filtration, Determine the filter bed depth for mm effectivesize anthracite coal filter bed. The equation describing filter collection efficiency can be rewritten as follows:
This project involves the addition of airassisted backwash to five sand filters at AECI's water treatment plant at the Thomas Hill facility. It is anticipated that airassisted backwash will improve the cleaning of the sand filter media while shortening the backwash time and using less water. Existing Filters Five cylindrical steel filters
