Water resource is not only an indispensable natural resource for human production and life, but also an environmental resource for living beings. With the aggravation of water resource crisis and the continuous deterioration of water environment quality, water resource shortage has become one of the world's most concerned resource and environment problems.

In order to alleviate the pressure of water environment pollution and water resource shortage, as a rapidly developing technology in the field of environmental engineering, the multi-disc screw press sludge dehydrator has been developed rapidly in recent decades. The multi-disc screw press sludge dehydrator can be widely used in municipal sewage treatment projects and water treatment systems in petrochemical, light industry, chemical fiber, paper making, pharmaceutical, leather and other industries.

Workflows of the multi-disc screw press sludge dehydrator:

1. The sludge in the sludge tank is transported to the metering tank through the sludge transfer pump, and the sludge volume is regulated through the liquid level regulating pipe in the metering tank, the excess sludge is returned to the sludge tank through the return pipe.

2. Sludge and flocculant are fully mixed in flocculation mixing tank through the mixer to form alum. The ideal alum is about 5mm in diameter.

3. The alum is concentrated in the concentration section by gravity, and a large amount of filtrate is discharged from the filter slit of the concentration section.

4. The concentrated sludge continues to move forward along the direction of rotation of the spiral axis, and is fully dehydrated under the internal pressure formed by the back pressure plate.

5. The dehydrated mud cake is discharged from the gap formed by the back pressure plate and the spiral body. The sludge treatment capacity and the water content of the sludge cake can be adjusted by adjusting the rotation speed of the spiral shaft and the gap of the back pressure plate. The discharge pipe of flocculation mixing tank is only used when cleaning the mixing tank.

Features of the multi-disc screw press sludge dehydrator

1. Short working cycle and high efficiency of the sludge dehydrator: high pressure extrusion can greatly reduce the water content in the sludge in a short time.

2. Low operating cost of the sludge dehydrator: full automatic control program, unattended, save operating costs.

3. Simple operation of the sludge dehydrator: the cleaning device is used, and the washing cycle can be set as required (adjustable on site).

4. Low power consumption of the sludge dehydrator: low speed operation, low motor power, low power consumption, saving power consumption.

5. The sludge dehydrator is widely used: it has strong corrosion resistance and is basically applicable to all solid-liquid separation projects.

6. High pressure compression of the sludge dehydrator: the elastomer of TPE makes the filter plate have good quality and can reach the maximum pressure filter of 25MPa, which greatly reduces the water content, saves the drying cost and increases the output.

7. drip tray can also be automatically opened and closed controlled by PLC system according to customers' requirements.
