It uses depth filtration where water passes through a graded media bed. Suspended materials attach to particles, and when pressure differential increases, an automatic backwash cleans the filter.

Q:What are the main applications for this system?

It is used for HVAC cooling towers, golf course irrigation, industrial pre-treatment for UF/RO, wastewater recycling, and mining water cleaning.

Q:Can the filter be customized?

Yes, we offer full customization including flow rate, tank quantity, tank size, and housing material (Carbon Steel or Stainless Steel) based on samples or designs.

Q:What is the minimum order quantity?

The Minimum Order Quantity is 1 piece.

Q:What are the payment terms?

We accept LC, T/T, D/P, PayPal, Western Union, and small-amount payments.
