Multi media filtration is often used in water treatment. Its detailed function is to remove turbidity from water source, reverse osmosis and ion exchange to soften the pre-treatment of desalination system. It can also be used to remove sediment from surface water and groundwater.
Selection of filter media for multi media filter:
(1) It must have enough mechanical strength to avoid quick wear and breakage during backwashing;
(2) The chemical stability is good;
(3) It does not contain substances harmful to human health and toxic substances, and does not contain substances harmful to production and affecting production;
(4) The selection of filter materials should try to use the filter materials with high adsorption capacity, high sewage interception capacity, high water yield and good effluent quality.
In the filter media, pebbles mainly play a supporting role. In the process of filtration, due to their high strength, stable gap and large pores, it is convenient for the filtered water to pass smoothly in the washing process; Similarly, in the backwashing process, the backwashing water and air can pass smoothly.
In the conventional configuration, the pebbles are divided into four specifications, and the paving method is from bottom to top, large first and small later.
The relationship between the particle size of the filter material and the filling height
The ratio of the height of the filter bed to the average particle size of the filter media is 800-1000 (design specification).
The particle size of filter media is related to the filtration accuracy.
