Basics of Multi Media Filtration (MMF)
ResultA Multi-‐Media Filter is used to reduce the level ofsuspended solids (turbidity) in incoming feed water. Suspended solids consist of small particles such as silt, clay, grit, organic matter, algae and other microorganisms. Incoming feed water that is high in suspended solids can cause a high-‐pressure drop and reduce the …

RECIRCULATING SAND FILTERS (RSF) DESIGN …
ResultAn important design factor in the sand filter dosing is the recirculation ratio (RR). The RR is defined as the ratio of the total flow through the sand filter to the forward (or average design) wastewater flow. Typical RR values for an RSF system range between 3:1 to 5:1. Besides determining the amount of wastewater to

ResultIt is the sieve size that retains 40% of the media (remember if it passes 60% it must retain 40%). The sieve size that retains 40% is 0.30 mm. Divide 0.30 by 0.15 and you get 2. So the UC for this example is 2. After the proper media has been selected, the amount of sand to be placed in the filter must be determined.
