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

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

Can a screw press handle oily sludge from food processing?

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.

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

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.

How does Kopay International ensure quality control?

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

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

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.

Why does polymer need a 3-chamber maturation system?

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.

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

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).

Are Kopay wastewater systems CE and ISO certified?

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

Paper Mill Sludge Dewatering Project in Philippines | KOPAY Screw Press Solution

Project Overview: High-Capacity Sludge Management in Bulacan, Philippines

Location: Bulacan / Manila region, Philippines
Industry: Pulp and Paper Manufacturing
Sludge Type: High-fiber paper mill wastewater sludge
Solution: [KOPAY-402 Heavy-Duty Multi-Disc Screw Press]

The Challenge: Handling High Fiber & Excessive Volume

A leading paper packaging manufacturer in the Philippines was struggling with their outdated belt filter press. The primary issues were:

Frequent Clogging: The high fiber content in paper sludge caused the filter belts to block every few hours, requiring manual cleaning.
High Water Consumption: Rinsing the old equipment consumed over 20m³ of fresh water daily.
Space Constraints: The existing wastewater facility had limited room for expansion, making bulky centrifuges impossible to install.

KOPAY’s Solution: The 400 Series Heavy-Duty Screw Press

After analyzing the sludge samples, KOPAY engineers recommended the KOPAY-402 series. This model was selected for its specific advantages in the paper industry:

Non-Clogging Design: The self-cleaning moving rings handle fiber-rich sludge without the need for high-pressure spray bars.
High Torque Drive: Equipped with a premium SEW-EURODRIVE motor to handle the heavy consistency of pulp waste.
Plug-and-Play Integration: The skid-mounted design allowed the client to replace their belt press within just 48 hours of delivery.

The Results: 75% Volume Reduction

Since commissioning in late 2025, the KOPAY system has delivered the following measurable results:

Sludge Volume: Reduced by 75%, significantly cutting down transportation and disposal costs.
Operation Cost: Energy consumption dropped by 40% compared to the previous system.
Maintenance: The factory now runs the dewatering process 24/7 with zero dedicated operators, thanks to the fully automated PLC control.
