Advantages of multi disc screw press in treating food sludge wastewater

Food has a wide range of industrial raw materials and a wide variety of products, and the amount and quality of discharged wastewater vary greatly. The sludge of the food factory has the characteristics of high moisture content and high organic content in the sludge. Therefore, the adjustment and modification of sludge is a key point.

There are many methods for modern food wastewater treatment, and the common methods currently belong to physical treatment, chemical treatment and biochemical treatment. Bioetp's screw press sludge dewatering machine adopts a combination of physical and chemical treatment methods. First, the wastewater is neutralized and adsorbed by dosing, followed by physical filtration and extrusion, and finally the mud cake is discharged for external transportation or further treatment. And the screw press dewatering machine can run unattended 24 hours a day, with a high degree of automation and low operating costs, which greatly saves labor costs and saves a considerable amount of money for enterprises.

1. Since the multi-disc screw press adopts the principle of screw shaft extrusion, it is suitable for processing organic sludge, and it is not easy to block, and the equipment has no wearing parts and is in good operating condition.

2. The multi-disc screw press can handle oily sludge, unlike the filter cloth of the traditional filter press that cannot adapt to oily sludge. The multi-disc screw press shaft of the screw press is squeezed axially and radially by the dragon piece and the dynamic and static ring pieces, which can be carried out smoothly. The sludge is dewatered, and the mud cake falls off freely from the mud outlet.

3. The screw press dewatering has its own spray system. During or after the operation of the equipment, tap water can be sprayed freely. Only 0.2PA water pressure is required, and the washed wastewater is freely sprayed to the entire dehydration BODy, and flows downstream to the filtrate tank. It will splash the water outside the equipment, and it is clean and hygienic, which is just suitable for the food factory, which has stricter hygiene requirements.

Being a solid liquid separation solution provider, Bioetp is with rich experience in design and manufacturing the wastewater treatment machine. More important, Bioetp is able to provide overall solution for separation and conveying with the rich product line and strong fabrication and assembly capabilities.
