2. Introduction:
Water soluble coolants get contaminated during course of operation in machine tools.
Major cause of disposal is bacterial contamination felt by bad smell and skin irritation.
Coolant is forced for disposal and treatment.
The idea behind the system is to apply the concept of “Treat and Reuse” instead of “Treat and Dispose”.
Recovered coolant is fit for reuse; back in the machine tool.
Recovery rate as high as 85%.
Recovered coolant can be reused many times till the coolant oil loses it’s properties and the emulsion gets broken.

3. Contaminants and their removal:
Tramp Oil:
Essentially due to lube oil present in machine tool. Removed by:
1. Desorber;
2. Tramp Oil Remover;
3. Activated Carbon Filter.
Suspended Solids:
Due to machining action. Removed by:
1. Stainless Steel washable strainer;
2. Tramp Oil Remover (till 40 microns);
3. Stainless Steel washable Bag Filter
(5 microns);
4. Spun Polypropylene cartridge
(5 microns).
Bacteria:
Due to water mixed for emulsion and suitably aided by Tramp oil. Removed by:
1. UV Dis-infection.

4. Tramp Oil removal:
Desorber:
Gravity based system to remove majority of free floating tramp oil. Oil removed through an adjustable funnel provided in the system. Separated oil can be sold.

6. Tramp Oil removal:
Activated Carbon cartridge
Spun polypropylene

Tramp Oil Remover:
Pressure membrane system where the coolant with oil is passed through oleophilic membrane and oil particles are trapped inside the membrane.
Activated Carbon cartridge:
Coolant passed through carbon for microscopic oil particles removal.

7. Suspended Solids Removal:
Suction Strainer:
Stainless Steel washable strainer of filtering capacity 150 microns
Tramp Oil Remover:
In addition to its application of Tramp oil removal, the membrane consists of filter cloth which filters the suspended solids level to less than 40 microns.
Bag Filter:
Stainless Steel washable filter of capacity 5 microns.
Spun Polypropylene Cartridge:
Filtering capacity 5 microns.

8. Suspended Solids Removal:
Bag Filter:
Stainless Steel backwashable filter of capacity 5 microns.
Filter media made from SS316 Dutch woven filter cloth
One time investment media washed and reused again and again

9. Suspended Solids Removal:
Spun Polypropylene Cartridge:
Filtering capacity 5 microns.

10. Bacterial Disinfection:
U-V Disinfection unit:
Coolant is passed in front of UV light as thin film exposing bacteria to them.
UV light at a wavelength of 253 nm penetrates the DNA of bacteria killing it.
The heat generated at that point vaporizes the bacteria without leaving any residue.

Main Skid- coolant recovery system
Standard Configuration:
Standard system comes with all the listed contaminant removal components.
Tank skid is optional.
This is recommended for companies with large number of machine tool sump capacities less than 200 litres.

12. System Illustration: Single Skid System:
For companies where large number of machine tool sump capacities are more than 200 litres.
Tank skid is not provided. Instead the main skid is taken near the machine tool for treatment.

14. Benefits: Waste coolant converted to usable coolant.
Nearly 85% of the coolant is recovered for reuse. (the losses are due to evaporation, tramp oil and chip drag out). There is no process losses.
Coolant can be removed for treatment as and when bacterial contamination is observed, refreshed and reused back in the machine tool.
Coolant can be recycled till the coolant loses it’s property and emulsion breaks.
There is no change in concentration because of treatment.
There is no need for conventional coolant treatment requiring emulsion breakage.
Systems are modular and can be augmented for increased capacities.
