Industrial Coolant Filtration and Recovery Systems

Coolant is recovered by briquetting scrap through coolant recovery containers. The scraps must then be processed using a coolant filtration system before it can be re-used with machine tools. Applied Recovery Systems, Inc. provides with every briquetter, a collection system for cutting fluids along with a pump to transport the coolant to either your existing filtration system, or an ARS, Inc. compact and cost effective chip and coolant recovery system. Filtration systems will vary depending upon the type of coolant to be recovered, but in general coolant mist recovery systems consists of three (3) main components.

Removal of Suspended Solids

Coolant Recovery System Through the compression of the chips, small particles are released which are suspended in the coolant. The first step in coolant recovery is to use the coolant filtration system to screen out those particles. This is accomplished through the use of a pressure bag filter, as well as a chip and coolant recovery system. Recovered coolant is pumped through the bag filter where the suspended solids are contained. The picture shows a bag filter and the suspended solids that have been removed. The bag filters can be replaced as necessary for a low cost.

Removal of Suspended Oil

Coolant Filtration System The second stage of the coolant recovery system removes oil from the machine tools themselves. This oil can be removed by sending the pre-filtered oil through coalescing filters which cause the oil to separate from the coolant. Coolant recovery in machining allows the oil then floats to the top of a small reservoir where it can be drained off periodically. The picture shows a small settling tank with oil on the top and clean coolant underneath. The coalescing filter is contained inside the reservoir.

Coolant Pumping System

The engine that drives the coolant recovery system is an air diaphragm pump. This pump reliably pulls coolant through the pre-filter, then through the coalescing filters and into the settling tank. The cleaned coolant is then sent back to the tank and collected in coolant recovery containers.

The coolant recovery system typically requires two (2) holding tanks, which are alternated in order to provide clean coolant that is suitable for re-use. Your Applied Recovery Systems, Inc. sales professional can assist you in finding the best coolant recovery system for your application.
