Horizontal decanter compatible with a wide variety of applications

This decanter is capable of continuously separating substances and ensuring stable performance for a long period. It is also easy to operate and can be operated unattended. It has realized significant cost effectiveness and cost reduction. Designed to save space, this decanter requires less installation space. It is used mainly for separation of liquid-liquid mixtures, including separation and dehydration of solid matter, purification and separation of liquid, and classification of solid matters for solid-liquid mixtures, and it ensures the efficient treatment of any kind of substance.

Track record

Water and sludge treatment, food and animal feed, pharmaceuticals, chemistry, recycling, energy, steel making, biology, civil engineering/architecture, etc.

Vertical decanter type centrifugal separator

巴工业

This vertical decanter offers distinguished separation performance of organic solvents, even in high-temperature, high-pressure environments.

Its vertical structure, which uses a mechanical seal, ensures thorough hermeticity. In addition, its pressure-resistant structure allows it to separate substances even under high pressure. Requiring less installation space is another advantage of the vertical decanter type centrifugal separator. It is designed to perform efficient separation even under severe conditions and can demonstrate outstanding performance in the deliquoring of resins, solid-liquid separation of slurry containing organic solvents, collection of catalysts, coal liquefaction, and solid-liquid separation of heavy oils, waste plastics, and the like at high temperatures and high pressures in chemical factories. We also offer the HT type centrifugal separator, which is capable of performing treatment at high temperatures up to 400°C.

Track record

Terephthalic acid, polypropylene, polyethylene, polyacetal, catalysts, protein, etc.
