Primary Treatment

The VTC (CVF SERIES) removes hydrocarbons and settleable solids from industrial wastewater and coolant.

In operation, this separator accepts industrial liquid waste in the inlet chamber. Here settleable solids fall to the bottom as sludge for periodic removal.

Then the waste stream enters the coalescing separation chamber. A matrix of vertically-postioned polypropylene tubes gives laminar flow characteristics to the liquid. The result is a liquid more responsive to gravity separation.

View the demo The tubes also provide a coalescing medium. Oleophilic in nature, they attract small oil globules which coalesce with other globules, increase in size and buoyancy, then break away to rise through the tubes to the top. Surface oil drains by gravity into a rotary pipe skimmer for discharge to a storage facility.

Performance that can be expected of the VTC(CVF SERIES) separator is:

  1. Removal of oil globules down to 20-micron size
  2. Reduction of oil content to 10mg/ltr

The VTC (CVF SERIES) removes even non-permanent mechanically emulsified oil. It leaves no visible sheen and traps solids too. In metalworking and similar applications, it removes more than 99% of tramp oils from coolants.

The VTC (CVF SERIES) incorporates a molded fiberglass construction. Internally reinforced, the structure withstands severe soil and hydraulic loadings.

The entire exterior surface is covered with corrosion-resistant gelcoat, integrally-colored and ultra-violet resistant. Since the envelope and fittings are corrosion-resistant, the separator can be installed in many hostile environments. No sacrificial protection required.

Animated Demo

Click the black “Begin Demonstration” button on the right:

  1. Start up – Unit is primed with clean water.Unit is now ready for operation.
  2. Industrial waste water enters the inlet and is dispersed thru two adjustable diffusers. Large oil droplets float to the surface, solids drop to the bottom and the small oil droplets attach to the coalescing tube bundles. When additional small oil droplets collide with previously attached droplets they form a larger more buoyant droplets and rise to the surface.
  3. Processed water flows under the oil retention baffle and over the final weir wall.
  4. Only the cleanest water exits the unit thru the bottom of the outlet tee pipe.
  5. Surface oil is periodically skimmed from the unit by manually rotating the slotted rotary pipe skimmer.
  6. Unit is designed for continuous operation.
