Under the Water Resources Act it is now illegal to discharge oil contaminated condensate from a compressed air system direct to either ground or sewer. Contaminated condensate is discharged from virtually every compressor. On average about 50 times the level of hydrocarbons permissible by Local Authority Inspectors will find its way onto workshop floors, down drains and into the air. This commonplace pollutant is difficult and expensive to control, until now. In order to overcome this problem it is necessary to install a condensate removal system, which removes the oil contaminant to acceptable standards and allows clean water to be discharged.
The CF Unit is a cartridge based filtration unit that will remove oil from compressed air condensate from the compressors, receivers, dryers and coolers. The product is manufactured in the UK in stainless steel, with an integral throwaway filter cartridge. The CF filtration Unit protects the environment from oil contamination and enables the user to meet local authority discharge consent limits.
Condensate, at pressure, enters the expansion chamber at the top of the unit.
A tortuous path separates the oil/water liquid from the air and exhausts the
air from the top of the unit to atmosphere, while the oil/water mix passes slowly
through the filtration cartridge. The oleophilic material inside the cartridge
has the ability to tenaciously absorb the oil, but not the water (the cartridge
will absorb all types of oils including synthetic and Polyglycol based oil).
The filtered water will then exit the unit under gravity allowing the operator
to discharge into the foul water drain. Once the cartridge is saturated it can
be replaced. The cartridge is of manageable size and weight and can be changed
by one person in a few minutes; disposal of the saturated cartridge will be
to local authority guidelines.
