The screw press, as a new type of sludge dewatering machine, is widely used in the manufacturing industry. It is particularly efficient in the treatment of animal husbandry waste, hence also referred to as a specialized sludge dewatering machine for livestock breeding. It effectively handles various excreta such as sheep manure, dung, pig manure, and duck manure.
The livestock industry is a pillar industry of the socio-economy. However, during the processing in farms, a significant amount of excrement and wastewater is generated. Negligence can lead to adverse effects on surrounding water quality, especially from livestock wastewater. Due to the accumulation of sludge from cleaning pig pens and excrement, livestock wastewater sludge typically has characteristics such as high COD levels, high concentrations of organic compounds, elevated permanganate index, deep saturation, and the presence of many virus-infected bacteria. Therefore, indiscriminate discharge poses extreme environmental hazards.
Using a screw press to deal with livestock sludge offers four major advantages.
Price
Firstly, the engineering cost of the screw press is moderate compared to other similar products, making it affordable for most small to medium-sized customers.
Space
Secondly, in terms of application, the compact size of the machine requires minimal indoor space, making it easy to move and transport. Its operation is straightforward and easy to understand, eliminating the need for customers to have a complex understanding of mechanical design to operate the machine effectively.
Energy Saving
Thirdly, in terms of environmental protection, the screw press is energy and water-efficient. It consumes significantly less power compared to centrifugal dewatering machines, and its automatic spray system minimizes water wastage during cleaning. Moreover, the treated water and squeezed sludge can be recycled, reducing water and electricity expenses for customers.
Service Life
In addition to cost-effectiveness, space-saving, and environmental protection, the key lies in its utility value. The value of the screw press depends on its long service life and low maintenance frequency. It rarely requires repairs. Minimal material damage even after prolonged use demonstrates its high quality and durability, making it a worthwhile investment.
