4. The outlet pipe is set at the bottom of the unit with smaller water resistance,convenient maintenance.
Feature:1. High filtration speed and low pressure loss,completely solve the problem of slow filtration speed and small flow of ordinary mechanical media filter.
2.With modular settings,small footprint,less piping,low investment,the space is reduced by more than 40%, and the piping engineering capacity is reduced by more than 50%.
3.More functions with manual,semi-automatic,fully automatic backwash operation to meet your needs.
4.The backwash water source can be selected within the system,water tower or external water source, and can be automatically switched (special requirements).
5.It can be a single filter unit or a combination of multiple filter units,and the processing flow capacity can be expanded arbitrarily.
6.The shell and tubes are carbon steel Q235B by phosphate surface treatment with internal and external surface anti-corrosion.It can also be made of stainless steel.
Working principle:Filter status:The unfiltered water is evenly distributed through the water distributor, and the water passes through the packing layer in the filter in a laminar flow state. When water flows through the packing layer, impurities are trapped within the packing layer. There are a plurality of evenly distributed water collectors at the bottom of the filter. The filtered water is evenly collected and taken out, and the flat flow filtration can filter the filter at a high flow rate, and still achieve better filtration effect.
Backwash status:As the impurities accumulate in the packing layer, the internal head loss will increase. When the inlet and outlet head loss reaches the set value or reaches the set time, the system will automatically activate the constant pressure difference device to switch to the backwash state. When the backwash is over, the hydraulic valve changes the water supply direction to achieve Backwashing makes it easier to clean the accumulated impurities.
