● Basic ideas

To reduce sludge disposal costs, a company should start by reducing wastes, and there are

three ways to do so.

<1>.Reduce waste water generation ● Enhance production management in factory.

<2>.Reduce sludge generation ● Improve the function of the sludge dewatering machine.

<3>.Overcome sludge moisture content ● Set up a sludge drying

● Design Principles of the Equipment

1. A set of specially designed sludge trolley with an airtight cover which can be positioned

quickly. Two sets of air circulation ducts which allow dry air to penetrate and circulate efficiently

through humid sludge to achieve drying and weight reduction purposes.

2. During sludge drying process, the operating time is about 16 to 24 hours. Factors]

affecting drying time include feed density and sludge pores.

3. Final sludge density reaches up to 65% to 85%, an increase from 20% to 30%. Sludge

weight is reduced by 2/3, and sludge volume is reduced by 1/3 to 1/2 depending on the sludge

quality.

4. Both dry and humid air circulates inside the machine. No gas emission and no waste

gas treatment tower required, making this machine a highly energy saving and economical sludge

dryer.

● Feature description of the sludge drying equipment

1. Condensation drying design extracts only water from the sludge. Moisture content

reduces to 35% after treatment. No secondary environmental pollution.

2. 1000 kg of filter cake is produced daily. Only 385 kg left after drying, reducing weight by

60%.

3. Occupies a small area, high economic efficiency. Easy to operate and safe.

4. Off peak power consumption.
