Scraper Type Self-cleaning Filter is excellent for cases where continuous, automatic pre-treatment of raw water with high turbidity, with reliable removal of suspended solids and algae, is required in water treatment, petrochemical, power and food industries.
Working Principle
The raw water enters the filter body, and the impurities in the water are adsorbed on the filter screen. The pressure difference is formed between the inlet and outlet of the filter. When the pressure difference reaches the set value, the motor starts and the scraper rotates to clean the filter screen. The cleaning process is completed in a short time, and the filter resumes normal operation.Simple structure and convenient maintenance.
Short backwashing time, large flow rate and low pressure loss (≤0.018MPa).
Automatic backwashing control, which can be operated by time or pressure difference.
High precision filtration, stable effluent quality and low backwashing water consumption (<1%).
Long service life of filter screen and good filtration effect.
Easy to install and use, low operating cost and simple operation management.
