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.

Introduction | Description: Low-temperature sludge drying equipment (also know for container type sludge dryer)

This dryer is capable of directly drying sewage or sludge with a moisture content of 83% to a dry sludge with a moisture content of 10%-30%, reducing volume by up to 90% and achieving up to 90% effective sterilization. It features low energy consumption, no pollution, and is widely used in the drying and reduction of municipal sludge and industrial sludge (such as dyeing, papermaking, electroplating, chemical, leather, pharmaceuticals, etc.). The dry sludge with a moisture content of 10%-30% can be further processed into harmless resources such as gasification, co-incineration, composting, or building materials.

Mainly according to the applications, there are container type sludge dryer…

—Why Invest in a Low-Temperature Sludge Dryer?

The final step in wastewater management is the most expensive: disposal. Our Low-Temperature Heat Pump Sludge Dryer can reduce sludge moisture from 80% down to 10%–30%, shrinking the total weight by up to 4:1. This results in a massive reduction in transportation and landfill costs, allowing the machine to pay for itself within 12–24 months.

—Key Technical Advantages

Heat Pump Dehumidification Technology: Unlike traditional thermal dryers, our system uses a closed-loop heat pump. There is no waste heat loss and zero odor emission, making it environmentally friendly and suitable for urban plants.
High Energy Efficiency: Our dryer consumes only 300-400kw/h of electricity to remove 1 ton of water, making it 50% more efficient than traditional steam or electric heat dryers.
Fully Automated Operation: Integrated PLC control allows for 24/7 “set and forget” operation. No manual labor is required for the drying cycle.
Safe & Durable: Operating at temperatures below 75°C, there is no risk of dust explosion or sludge burning. All internal parts are made of corrosion-resistant stainless steel.

—Key Features of our Wastewater sludge dryers:

The moisture content of the dried sludge can be adjusted to between 10% and 50%, with reduction rates exceeding 80%.
No risk of odor leakage, ensuring a clean working environment without the need for expensive odor control systems.
Direct installation within the facility is possible, allowing for centralized sludge disposal. Additionally, condensate water can be discharged directly without secondary treatment.
Efficiently dries wet sludge with an initial moisture content of 83% to a moisture content of 30%. Operating costs are as low as 180 kWh per ton
Achieves a comprehensive dehumidification performance ratio of over 4.2 kg of water per kWh. This exceeds industry standards by double the efficiency, with energy savings up to 50% compared to traditional low-temperature drying methods.
Fully enclosed system and incorporates heat pump heat recovery technology, ensuring zero heat loss and maximizing thermal efficiency.
Operating at a low temperature range of 40-75°C within a fully enclosed system, our process ensures safety with no dust hazards. With oxygen content below 12% and dust concentration below 60g/m³ during the drying process, there’s no risk of dust emissions or explosion hazards. Additionally, the discharge temperature is below 50°C, eliminating the need for secondary cooling and enabling direct storage
