Date:2018-07-21From:DZ filter press
Most of sewage/ sludge treatment plant don’t know how to select the size of machine in purchasing plate and frame filter press for procesing the sewage/ sludge produced by every day/sludge, here takes Henan Dazhang filter equipment Co., Ltd., as an example, introduces the selection methods of plate and frame filter press.
There are mainly below methods:
1.Per wet sludge amount
2.Per dry sludge amount
3.Per suspended solid amount
In these methods, the required data per wet sludge amount is easy to obtain and the calculation result is reletively accurate, so it is widely used:
1.Treatment amount: the sewage/ sludge amount before filtering-A
2.Filter cycle: time of every filtering
3.Solid content of sewage/sludge before filtering-a
4.Solid content of sewage/sludge after filtering
The filter volume of plate and frame filter press is B, base on solid balance principle, Axa=Bxb，so B=Axa/b
Take a ceramics factory as an example. The ceramic waste water that needs to be filtered every day is 80 tons, the working time is 10 hours, the filtration cycle is 1 hour. The solid content of wastewater before filtering is 20%, the solid content of the filtered cake is 70%, use the method of wet sludge amount: 2000 Lx0. 2/0.7 = 570L, so select a plate and frame filter press with filter volume 570L is workable.
The sales and engineer of Henan Dazhang filter equipment Co.,Ltd, will carefully check these related data of customer at the beginning, and select suitable model according to different customer’s differenet needs.
Dazhang company, is the professional manufacturer of plate and frame filter press, the leader of filter press industry!
