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 its properties and the
  emulsion gets broken.

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
• (25,5 and 2 microns)
• Bacteria
• Due to water mixed for emulsion and suitably
  aided by Tramp oil. Removed by
• 1. UV Dis-infection.

Operational Sequence

• Water soluble coolants from machine tool is
  sucked out through Vacuum suction system present
  in the recovery system.
• This coolant is stored in the collection tank.
• Once suction phase is over, the coolant enters
  Desorber for floating oil removal.
• Then it passes through filtration systems.
• After filtration, the coolant passes through the
  bacterial disinfection unit.
• The coolant after disinfection can be reused for
  machining.

Vacuum Suction Unit

• Vacuum Unit
• Electrically operated vacuum motor with
  collection tank as a single unit. The collection
  tank capacity is 200 litres. The tank is provided
  with chip trap and motor protection seal to
  prevent coolant entry into Vacuum motor.

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.

Tramp Oil removal

• 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.

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 backwashable washable filters of
  capacities
• 25 microns
• 5 microns
• 2 microns

Suspended Solids Removal
Bag Filter

• Stainless Steel backwashable filter of capacity
  25, 5 and 2 microns.
• Filter media made from SS316 Dutch woven filter
  cloth
• One time investment media washed and reused again
  and again

11
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.

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
  its 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.
