The PROBLEM

Air compressors, widely used throughout industry, can produce considerable amounts of oil-contaminated condensate. This contamination must not be discharged directly into open drains, public sewers or natural watercourse.

Oil quickly reduces the dissolved oxygen content of water, which sustains animal and plant life and the bacteria essential for the aerobic digestion of sewage in Water Treatment Plants. As a result, most countries now have environmental laws placing strict limits on the discharge of industrial effluent containing oil.

The SOLUTION

The low cost, effective solution is a SAO oil/water separator from General Air Products. Installed as part of the compressed air system, it simply reduces the oil concentration in the condensate to permitted levels, so that clean water condensate can discharge safely into the drains. This leaves a relatively small amount of concentrated waste oil to be disposed of by the most economic of legitimate means.

OPERATING PRINCIPLE

The oily condensate enters the expansion chamber of the SAG under pressure. Here, the excess pressure is eliminated without creating turbulence in the separation container. The larger particles of dirt are retained in the removable waste collector. Inside the separator, the oil accumulates on the surface by means of spontaneous separation and is eliminated through the outlet by means of an adjustable overflow into the collection can with an overflow protection (included in supply). The partially separated condensate then flows through an oleophilic pre-filter, then through an activated carbon filter (SAG340 and SAG 1020 two activated carbon filters) and is finally drained through the outlet. The pre-filter retains the remaining drops of oil, while the activated carbon filter captures all the residue oil. The water level can be checked by means of the level indicator while samples of water can be taken through the bleed valve.

The performance of oil/water separators and the economic service life of activated carbon are dependent upon the degree of oil dispersion and emulsification. The frequency with which activated carbon filter bags require changing will therefore be determined by the following factors; compressor type and capacity; lubricant used, condensate collection system, temperature, humidity and maximum legal oil discharge limits.
