Small-Particle-Separation-FiltrationA separator enabling separation of particles of sizes down to 10µ (option 3µ) by settling them in a motionless liquid volume. Small particles, which accumulate in process fluids particularly hard metal grinding, are difficult to separate in a liquid which is moving. However by settling out particles in a motionless volume it is quite possible to attain high levels of separation with particle as small as 3µ.

This is the working principle of our Decantor Separation System. Periodic settling of the carrier fluid in a motionless liquid volume installed with a lamella package provides an environment where the smallest particles are allowed to separate.

The Decantor is equipped with clean tank, dirty tank, supply pumps and automatic topping-up system. The lamella package is sized according to process flow rate and has a built in automatic self cleaning system. Separated particulate in the form of sludge is collected automatically in standard 200 litre drums. Total throughput capacity up to 2000 litres/min.

As with all our systems the Decantor is classed as a lean maintenance unit, once set up it requires little in the way of human intervention and uses zero consumable media.

Application: Hard metal grinding, honing, EDM fluids
Separation quality: Down to 10µ (option 3µ)
Throughput capacity: Up to 2.000 lpm/unit


Application Example

Carbide grinding is a perfect application for our Decantor system. The waste stream is not difficult to separate using conventional filter systems and often the waste is contaminated with the filter media. The Decanter is media free and the resulting waste stream is collected automatically in barrels ready for recycling this valuable commodity.


The barrel here has only to be capped off with a lid, replaced with an empty one and the process continues automatically. The carbide is extremely concentrated and has little of the grinding fluid left in the mix so is more acceptable to recycling companies. Its also very heavy!
