In order to obtain a higher solid recovery rate and a lower water content of the sludge cake, the sludge from the sludge tank is often added with PAM (flocculant) solution before it is dewatered in the centrifuge or screw press. It is also considered…

Lower investment in infrastructure construction and better on-site operating environment Compared with traditional filtration equipment (plate, frame, belt, etc.), the high-performance centrifuge has a compact structure, high efficiency, and covers an area of about 1/3. No need to be equipped with auxiliary air sources, high-pressure…

Oil field drilling requires drilling oil-based slurry according to the drilling depth and geological conditions. Its basic composition is oil, water, organic clay and oil-soluble chemical treatment agent. The oil-based slurry is resistant to high temperature and salt calcium corrosion is conducive to the stability…
