Sludge vacuum pump is a high load strong suction pneumatic vacuum transfer pump, also called solid vacuum pump. The vacuum is up to 25 inches of mercury (vacuum 85Kpa) and the head of the discharged water is up to 80 metres. Its unique structural design enables it to operate in particularly difficult environments with low maintenance, and it can transport materials with more than 80% solids and high specific gravity materials at high speed. It is characterised by a high efficiency venturi that generates a vacuum of up to 25 inches HG (mercury column) under strong air flow to pump the material, which is then conveyed under positive pressure with virtually no wear parts. Commonly used in the petroleum industry for drilling cuttings conveying, oily sludge conveying, tank cleaning operations, waste pumping over long distances, and mineral and waste conveying. In addition, it is also widely used in the chemical, mining and industrial fields for solid conveying, solid-liquid mixture conveying, and vacuum extraction.

At GN Separation, we are committed to providing advanced, efficient solutions for liquid and solid separation across various industries. One of our key offerings is the Slant Plate Clarifier, also known as the Inclined Plate Clarifier. This innovative piece of equipment is designed to optimize the separation of solids from liquids in a wide range of applications, delivering superior performance in a compact footprint.

GN oil sludge system is to use chemical to wash the oil sludge with heat to temperature of 60-70 degree. After washing the sludge wil be pump to GN sepeartion equipment to do solid and liquid separtion. The recycled water can be reused in the washing process, and the oil is clean enough to sell to the refinery company, the solids contain less than 2% oil which can be sent to biodegradation or thermal unit for final disposal if needed. 

Recently GN have completed a small oil sludge system, It will be sent to oversea customers soon. GN have 2 different model, namely GNOST-05C and GNOST-15C for the oil sludge system according to diggerent handling capacity. The GNOST-05C is an advanced oil sludge treatment system designed for efficient and effective processing of oil sludge. It utilizes cutting-edge technology to separate oil, water, and solids, ensuring compliance with environmental standards.

The oil sludge system is meticulously engineered with a GNLW364FT decanter centrifuge, a chemical dosing system, and a mud feed screw pump, all housed within standard containers for enhanced transportation efficiency and ease of installation. This innovative packaging approach significantly boosts the maintainability and protection of the equipment, ensuring a long service life and minimal downtime.

Treatment Processes

heating and Pre-mixing module

There is a pre-mixing tank for the preparation of the material and then heat the material to 60-70 degree.

Screening module 

There is vibration screen in this module, in order to remove the corase particle there, and feed in the fine particule to the next module directly.

Chemical dosing unit

add some polymer here to help the decanter to make the solid and liquid separation more efficient.

Decanter centifuge module 

The material will be feed in the 2-phase decanter centifuge at first to do the solid liquid sepation, and then the separated liquid will be feed into the 3-phase decanter centrifuge to get the oil-water-solid separation.

GN Separation has successfully delivered 3 sets of GNLW654-VFD decanter centrifuges to support a municipal wastewater treatment project in a North African country. This project not only includes the installation of the dewatering centrifuges but also features a 6500L chemical dosing unit, ensuring high precision and efficiency in the sludge treatment process.
