During the past decades, China has developed quite rapidly and soon becomes one of the biggest resources consumers in the world. Meanwhile, with the largest population in the world, the long-sight China government put an eye on environment protection quite strictly. According to laws and regulations, all oily sludge must to be treated well before dumping.


As a well known brand, GN Solids Control always comes up with professional solutions. Recently, GN just provide to a domestic client in Tianjin a combination of equipment including a decanter centrifuge GNLW454ET and GNSD90 disc stack separator.

1. GNLW454ET is a centrifuge model with 18 inch bowl diameter, and a length diameter ratio of 4. It is a high speed centrifuge with bowl rotation speed up to 3000RPM. Comparing with GNLW452 with 2 as bowl length-diameter ratio and GNLW453 with a ratio at 3, the GNLW454 with a longer bowl could give clearer separation result, especially for the material with higher viscosity, for example, after chemical dosing procedure.

2. GNSD90 disc stack is a 3 phase separator which can separate the oil, water and solids. But it has some limit for solids size input, that’s why before the disc stack there should be a decanter centrifuge for separating out the particles from 2 to 5 microns. After the disc stack, the oil can be recovered to sell for money, the water can be reused in the same separation unit for dilution and the solids particles are easier for future treatment or discharge.

GN has different models of decanter centrifuges and disc stacks for meeting the different capacity requirements. And if necessary, GN could also help to provide the equipment before the decanter centrifuges according to the material condition and requested treating results. Like the shale shaker, chemical dosing unit and preheating mixers.

GN Solids Control is an API Certified manufacturer, and also certified by ISO and HSE. GN Solids Control has its products sold to more than 70 countries in the world. If you need more information or similar project, welcome to contact GN Sales directly for consultance.
