small footprint; no need to replace the filter cloth and other consumables, high efficiency and continuity, can be operated 24 hours a day uninterruptedly, large processing capacity, high degree of automation, adaptability, through the adjustment of the drum speed, differential speed, the amount of feed, and other parameters, you can deal with the different nature of the sludge, the layout of a flexible. Compact structure, small footprint, can be installed on the ground or overhead arrangement, maintenance is relatively simple, the main moving parts are drum and spiral, routine maintenance is relatively simple. Suitable for large municipal sewage plants, petrochemical, food processing, paper, pharmaceutical and other industries that produce large amounts of sludge and have high environmental and automation requirements. In addition to mainstream sludge dewatering, centrifuges have other uses in some specific scenarios: 1. Pre-treatment: removal of high-density suspended In some industrial wastewater (such as mining, metal processing, steel industry), it may contain suspended particles of higher density (such as metal shavings, mineral powders, gravel, etc.). Sand sedimentation centrifuges or disc centrifuges can be used to quickly remove these heavy substances in the pre-treatment stage, protecting subsequent pumps and treatment facilities from wear and tear.2. Separation of oil, water and residue three-phase In food processing (e.g., animal slaughtering, oil and grease mills), petrochemical and other industries, wastewater may contain oil, grease, water and solid impurities at the same time. The specially designed three-phase centrifuge can separate these three phases at the same time.3. Solid-liquid separation after chemical coagulation When dealing with certain difficult-to-degrade wastewater, chemicals (such as PAC, PFS) will be added to produce flocculants. Centrifuge can quickly separate these chemical sludge to achieve the clear liquid discharge or reuse.
Centrifuge is the key indispensable equipment in modern industrial wastewater treatment, especially in large-scale sludge dewatering. Their high efficiency, continuity and cleanliness have made them widely used in many industries, and despite the challenges of high energy and pharmaceutical costs, their overall advantages are still outstanding.
