Analysis of the characteristics of sludge from water plants:

Sludge from water plants mainly comes from sedimentation tanks and filters. The sludge discharge from the sedimentation tank is mainly composed of chemical flocculation sedimentation. Chemical precipitation is composed of suspended solids, dissolved colloids, organic matter, microorganisms and added water purification agents in the raw water, accounting for about 0.5% to 3% of the raw water volume, and is the main object of sludge treatment in water plants. Compared with softened sludge (such as domestic sludge), flocculation and sedimentation sludge is not easy to dewater, and traditional sludge dewatering equipment is easy to block during processing. In addition, there are many inorganic substances such as sand and gravel contained in the sludge of the waterworks, which will also cause serious wear and tear to the general sludge dewatering equipment.

Advantages of screw press in treating sludge from waterworks:

1. The degree of automation is high, and the whole process can be unattended for 24 hours, which can truly be fully automatic, saving a lot of human, material and financial resources.

2. Save energy. In terms of water consumption and electricity, energy consumption can be greatly saved, and energy costs of tens of thousands or even hundreds of thousands of yuan can be saved a year.

3. No secondary pollution, small footprint, simple process, almost no maintenance, convenient and trouble-free.

However, when dealing with sludge from water plants, try to choose a variable frequency motor, so that the motor has better pressure resistance, heat dissipation, and noise reduction and is safer.
