No matter what kind of filtration equipment, will encounter a lot of problems in the use of the process in which the effluent quality instability is the most major one, today we have an air filter equipment - quartz sand fil ter as an example, for everyone to talk about the factors affecting quartz sand filtration equipment water effects!non woven fabrics
First, we introduce the quartz sand filter, which is a quartz sand as a filter medium, high turbidity of the water through the filter under pressure, effectively blocking one of the suspended solids, organic matter, micro-organisms, as well as some heavy metals ions and other substances, and thus play a role to reduce the turbidity of the water, purifying water quality of a device, and then in the process of equipment used, the factors that affect the filtering effect how, what does
, Flow uniformity
Whether the equipment running or backwash when we try the water requirements of various sections should be evenly distributed, we first have to do a good run of the drainage system, and only gradually uniform flow, the filter effect can want to flow even ly protection.
Second, the speed of filtration
Filtering speed of the equipment to be appropriate, because if the speed is too slow, it will lead to reduced processing unit filter area, in order to achieve a certain amount of water will increase the filtration area, which also is to increase the use of cost. However, too fast, not only will increase the loss, also makes the filter cycles, water quality will be significantly affected, therefore the most appropriate filtration speed is generally about 10 - 12m / h.
Third, the backwashing
As we all know, the main role of the backwash is cleared the equipment filter layer of residual contaminants, restore the filtration performance of the filter media to these pollutants rinse must guarantee the backwash velocity and time. This and the size and the relative density of the filter material, the expansion rate and water temperature are closely related. Only protection equipment backwash effect filter effect will be secure.
