Wuhan medium filter selection principle:
(1) Must have sufficient mechanical strength to avoid rapid wear and breakage during backwashing;
(2) good chemical stability;
(3) It does not contain harmful and toxic substances to human health, and does not contain substances that are harmful to production and affect production;
(4) The choice of filter media should be as far as possible the use of adsorption capacity, large capacity of sewage interception, high water production, good water quality filter material.
In the filter media, the pebbles mainly play a supporting role. In the filtration process, due to its high strength, the gap between them is stable, and the pores are large, which facilitates the smooth passage of the filtered water in the forward washing process; similarly, backwashing is performed. In the process, backwash and backwash air passed smoothly.
In the conventional configuration, the pebbles are divided into four kinds of specifications, and the bedding method is from the bottom up to the top and then the back.
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 material is 800 to 1000 (design specifications). The size of the particle size of the filter is related to the filtration accuracy.
