How stainless steel filters work

How stainless steel filters work

Regardless of the filtering equipment, it is very important to grasp the correct application of the equipment before putting it into operation. Today we are introducing you to the method of correctly using the stainless steel filter. Let's take a look at it!

1. Washing: The so-called positive washing is a normal filtering action. It only needs to change the valve to the direction of washing. The sewage is sent to the valve of the sand filter after being pressurized by the booster pump, and passes through the multi-way valve. Constantly switching, the water passes through the sand layer and then enters from the water cap, flows upward from the center rod, and finally discharges from the sewage outlet.

2, backwashing: backwashing is also very simple, just change the valve to the direction of backwashing, the basic operation process is the same as the above steps, the water rushes from the bottom of the sand layer, so that the sand layer keeps rolling, so that The accumulated pollutants can be washed away and finally discharged from the sewage outlet.

3. Operation: The principle is the same as the previous wash and back wash. Since the multi-way valve can be switched, the water will eventually drain from the water outlet.

4. Filtration: First, the valve is turned to the backwashing direction, and the water will be washed from the water inlet through the center rod from the bottom to the top, and the dirty water is discharged from the sewage outlet.
