Dissolved Air Flotation CPF/PWF type

The CPF and PWF flotation units are compact built flotation units which are suitable for the treatment of normally polluted wastewater.

The CPF and PWF units are designed to get a complete laminar flow through the unit in combination with a small footprint. Therefore the unit is executed with a counter current plate pack.

Due to this plate pack the internal surface is increased, which results in a very stable and laminar flow through the unit. Under these circumstances optimal separation of suspended solids, oils, fats and other flocculated materials takes place.

The flotation unit consists of a flotation tank equipped with the special "low friction" inlet compartment, an aeration system, a plate pack and a sedimentation discharge system with sludge compartment. The unique sedimentation discharge system contains a skimmer with static sludge thickener which results in a high dry solids load of the floating sludge.

Furthermore the flotation unit can be equipped with a unique self cleaning aeration system. In general an AISI 316 recirculation pump is used to prevent corrosion.

Depending on the type of wastewater a PWF unit (with auger) or a CPF unit (without auger) is applied. 

Advantages:

  • very compact built units.
  • suitable for non-chemical solutions.
  • suitable for normally polluted wastewater.
  • units up to 125 m3/h can be transported in standard sea container.
