Product Q&A
Q:How does the automatic backwashing process work?
A:
The system uses a pressure differential switch to sense when the filter bed is clogged. Once the preset value is reached, the controller initiates backwashing, where pressurized water flows in reverse to suspend and wash out dirt particles through the back-flush valve.
Q:What filtration media is used in this sand filter?
A:
The standard media is Quartz Sand. The filtration degree depends on the effective size of the bedding and water velocity, using depth filtration to capture suspended materials.
Q:Can the filter be customized for specific needs?
A:
Yes, full customization is available. Options include tank quantities (1-10), tank sizes (16-96'), housing materials (Carbon Steel/Stainless Steel), and media types.
Q:What is the minimum order quantity (MOQ)?
A:
The minimum order quantity is 1 piece.
Q:What payment terms are accepted?
A:
Accepted payment methods include LC, T/T, D/P, PayPal, Western Union, and Small-amount payment.
