Question 1

Why is a multi-disc screw press better than a belt filter press?

Accepted Answer

A multi-disc screw press offers a 90% reduction in wash water, fully automated 24/7 operation, and a non-clogging design.

Question 2

Can a screw press handle oily sludge from food processing?

Accepted Answer

Yes. The multi-disc screw press is specifically designed for oily sludge. Its unique structure of fixed and moving rings creates a self-cleaning mechanism that prevents clogging.

Question 3

How much can a low-temperature sludge dryer reduce sludge volume?

Accepted Answer

A low-temperature heat pump sludge dryer can reduce sludge volume by up to 80%, shrinking 4 tons of wet sludge into 1 ton of dry granules.

Question 4

How does Kopay International ensure quality control?

Accepted Answer

We perform raw material verification, motor performance checks, and a 24-hour factory fatigue test before packing every order.

Question 5

What is the typical power consumption of a sludge dewatering screw press?

Accepted Answer

Kopay’s multi-disc screw presses are highly energy-efficient. A model with 300kg-DS/h capacity typically consumes only 1.5kW to 2.2kW.

Question 6

Why does polymer need a 3-chamber maturation system?

Accepted Answer

PAM requires 60 minutes of aging to uncoil molecular chains. A 3-chamber system ensures perfect maturation, preventing fish-eyes and saving 20% in chemical costs.

Question 7

How do micro-bubbles improve Dissolved Air Flotation (DAF) performance?

Accepted Answer

DAF systems use 20-40 micron micro-bubbles to attach to suspended solids and oils, resulting in a 95%+ removal rate of Fats, Oils, and Grease (FOG).

Question 8

Are Kopay wastewater systems CE and ISO certified?

Accepted Answer

Yes. Our production partners maintain ISO9001:2015 and CE certification, ensuring all equipment meets international export safety standards.
