The ZEPHYR® Air Flotation System is extremely efficient in Pulp and Paper Mills, Petrochemical Industries, Meat Processing Industries, and Municipal Wastewater Treatment.

ZEPHYR® Features

  • Precisely separates liquid phases – ideally suited for oil and grease recovery.
  • Micro-fine bubbles adhere to minute solids, floating them to the surface – excellent for meat and poultry packing plants, vegetable processing plants, pulp and paper mills and petrochemical plants.
  • Greatly enhances skimming operations.
  • Ideal for incorporating gases into liquid media, including: CO2, ozone, CL2, methane, nitrogen, etc.
  • All stainless steel construction – The ultimate in corrosion and chemical resistance.
  • Solid shaft and sealed bearing design (patented) – Virtually no maintenance.
  • Standard components such as: motors, bearings, and couplings.
  • The diffuser disc is easily disassembled for cleaning with soap and hot water.

ZEPHYR® – How It Works

The ZEPHYR® unit mounted vertically in a tank with the motor above the water and the diffuser disc below. Each unit features diffuser disc that incorporates fine holes near its perimeter for ultra-fine bubble diffusion into the liquid. The motor spins the diffuser disc, creating a low-pressure zone at the disc’s diffuser ports, which draws air, or gas, from above the liquid surface. That air, or gas, then proceeds down through the draft tube, into the disc and out of the submerged diffuser ports. Each bubble exits through a hole in the edge of the diffuser disc. The spinning disc shears it into microscopic air bubbles measuring from 10-100 microns in diameter. These air bubbles adhere to minute solids such as oil and grease. The bubbles slowly rise to the surface around the unit, bringing the solids to the surface.

ZEPHYR installations are found in the petrochemical industry, pulp and paper mills, food processing facilities, and in municipal wastewater treatment.
