Process

Details
  • Technofluids, in its process, combines a novel application of gas flotation technique with its proprietary WaterWall® separation technology. This system is a once through system, i.e., the contaminated fluids are treated only once to completely remove tramp oils, suspended contaminants and bacteria.
  • In Technofluids’ process, bacteria are prevented to proliferate because an ozone generator applies a specific volume of ozone to the coolant, during the mixing into the liquid mixing zone, which kills mold, yeast, fungus, and bacteria.
  • Technofluids’ recovery system includes a first tank where the gas stream is passed into the liquid mixing zone, at a predetermined flow velocity and intimately mixed with the liquid stream to disperse or dissolve the gas stream into the coolant altering the specific gravity differential between aqueous liquid and the suspended contaminants.
  • This novel technology comprises forming a flowing stream of aqueous liquid containing the suspended contaminants and passing the flowing stream into a gas - liquid mixing zone under pressure at a desired flow velocity.
  • A stream of gas is also passed into the gas-liquid mixing zone to intimately disperse and dissolve the gas stream into the liquid phase and suspended contaminants phase to form a multiphase gas-contaminants liquid stream.
  • The flow velocity of the multiphase stream increased along with a substantially simultaneous decrease in pressure to finely disperse the gas throughout the liquid and suspended contaminants phase of the stream.
  • The flow velocity is then decreased with substantially simultaneous increase of pressure to further finely disperse and intimately dissolve the gas stream throughout the water phase and contaminants phase of the stream.
  • The abrupt alternate fluctuation of the stream flow velocity and pressure results in highly homogeneous multiphase mixture of the liquid, contaminants and gas.
  • The pressurized multiphase liquid contaminants-gas mixture is next passed into a zone having an increased volume flow area which is maintained at a reduced pressure relative to the stream to cause the dissolved gas to break out of solution and along with the dispersed gas form finely dispersed gravity-density reducing microscopic bubbles that attach to themselves and to the suspended contaminants to increase specific gravity differential between the contaminants and liquid.
  • The contaminants are thus caused to separate and float with the minute gas bubbles to the surface of the liquid, while the water phase is passing through the WaterWall® separator for complete and final oil separation.
  • It is important to notice that just because the final oil separation is not due to some kind of mechanical effect, but solely to natural strong molecular and/or electrostatic attraction/repulsion forces, the dispersed oily phase is inhibited to pass through the WaterWall® barrier remaining above the water film until macroscopic droplets are being formed by collision with some other arriving oil droplets, then buoyancy forces bring them towards the upper surface of the separator where they are dispersed into the existing oil layer that is continuously skimmed out recovering the oil phase, while, in the cleaned coolant tank the fresh coolant is mixed with the cleaned coolant in order to “recharge” the coolant prior to dispensing back to the machine tool.
