Automatic backwash filter not only has good pollution control effect, but also has reasonable cost and cost-effective filtering device

Automatic backwash filter It is guided by the pilot valve operation realized by pulse. The filter element is flushed in turn. When one filter element is cleaned, the other can work normally and can be flushed many times. This process not only reduces the trouble of manual washing, but also ensures the continuous operation and improves the working efficiency. The increase of backwashing frequency helps to prolong the service life of filter element.
The automatic backwash filter is very flexible and can be operated under aerobic and anaerobic conditions. It can be used alone or in multiple steps. The device has the function of filtering raw water and actively cleaning and discharging the filtering elements. The system can supply water continuously when cleaning sewage. Compared with the traditional filter, the device has high initiative, large treatment capacity, self-cleaning and sewage discharge, uninterrupted water supply, and wide use of the same surface.

Installation technical essentials of automatic backwash filter:
1. The installation only needs to connect to the pipeline according to the water inflow direction indicated by the arrow on the full-automatic backwash filter barrel;
2. When the water temperature of the filter does not exceed the self cleaning temperature, it should not be used;
3. The sewage pipe should be connected to the drainage ditch nearby, and the sewage should be kept smooth;
4. In order to observe the working condition and daily operation of the system, the pressure gauge and manual valve should be installed at the inlet and outlet of the automatic backwash filter;
5. During blowdown, the filter screen should be flushed for 10-20 seconds by opening and closing the valve according to the blowdown condition;
6. The filter specification should match the installation pipeline. When the filter flow can not meet the pipeline requirements, two (or more) filters can be installed in parallel or side by side;
7. In the design and installation of automatic backwash filter, the drain outlet should be at the lower part as far as possible, so as to facilitate the smooth discharge of debris;
8. The installation site has three-phase 380V power frequency AC (three-phase four wire system). The sewage pipe should not exceed 5m to avoid back pressure;
9. For DC system, pay attention to filtration accuracy, pretreatment, pressure and intermittent system.
 
Sewage treatment is very important to environmental protection. In many ways, backwash filtration equipment is an ideal choice for wastewater control. Automatic backwash filter not only has good pollution control effect, but also has very reasonable cost. Very cost effective filter
