Grey water consists of everything except toilet waste. It is rich in organic matter, but less polluted than black water and can be reused for cleaning, irrigation, toilet flushing and car washing. 75% of domestic wastewater is composed of gray water.
The self-cleaning filter consists of Electric motor, Automatic drain valve, Screen, Cleaning brush, Water inlet, Water outlet.
How to clean?
When the pressure difference between the inlet and outlet of the filter reaches the preset value (0.5bar) or the time setting value, the self-cleaning process will start. The entire self-cleaning process consists of two steps: Open the diaphragm drain valve on the upper end cover; the motor drives The stainless steel brush in the filter screen rotates, and the impurities caught by the filter screen are brushed down by the steel brush and discharged from the drain valve.
The entire cleaning process takes about 15-30 seconds, and the system continues to flow during cleaning. The entire operation process is controlled by a control box equipped with the machine.
How does control system work?
Adopting industrial single PLC automatic control ( English version), backwash can be controlled according to pressure difference or timing, and can be manually or automatically cleaning. On-site set filter interval time, cleaning time. Operation signal, cleaning signal, fault signal output and communication signal output.
Manufacturing material
Shell: carbon steel sprayed with epoxy resin (stainless steel can be used on request)
Performance
Uninterrupted water supply: There is very little water during cleaning, which is 1% of the water output. The flushing time is 2-15 seconds, and the entire system has an uninterrupted water supply.
High filtration precision: The filtration precision can reach 20 microns, and there are various filter screen optional.
Large filtration area: The effective filtration area of the standard filter is 7-40 times the entrance area.
Reliable cleaning: There are a variety of control methods, manual, pressure difference, time, PLC program logic control and other options.
The installation is economical and simple: the structure is diverse, suitable for installation in various situations on the spot, without affecting the operation effect.
Long service life: Normally, the service life is more than 10 years. The filter screen is stainless steel. It can be easily replaced with different specifications according to needs.
