Selection of Screw press sludge dehydrator

 

screw press, as a new sludge dehydrator equipment, will be used as the main sludge treatment equipment in the design stage of many sewage treatment projects. There are many screw filter press manufacturers on the market, and the scale, model and price of each manufacturer are different. As the filter press is still a non-standard product for the time being, there is no perfect industry standard, which will confuse users when choosing.

First, it depends on whether it is a real manufacturer and whether it has a perfect production line. Whether it completes the cutting of rings, the processing of spiral shafts, and the assembly of equipment by itself. Many sludge filter press manufacturers do not produce and process their own rings and spiral shafts, and are only responsible for assembly, which makes it difficult to ensure the quality of the equipment produced.

Second, we need to look at the processing technology of the ring and the spiral shaft. If the flatness of the ring is not enough, and it has not been leveled and the cutting stress has not been eliminated, then we can only increase the thickness of the gasket to avoid the friction between the ring, thus reducing the effect of sludge dewatering.

Third, we need to see whether we have our own patented technology. After all, the number of years that the screw press has entered the domestic market is not long, and the technology is not as mature as the traditional filter press. This requires the manufacturers of screw press to constantly innovate and improve the screw press technology. Manufacturers with their own patents can see that they have the spirit of craftsmanship, and there is no problem in controlling the quality of equipment.

If there is a problem in the sludge treatment process, it will affect the whole sewage treatment, so the manufacturer of screw filter press must be careful.
