Abstract
Apparatus for the biological purification of cutting oil, such as used in metal machining apparatus, is disclosed. The invention herein provides a suitable aerobic environment for remediating cultured aerobic bacteria. These beneficial bacteria act to break down the hazardous organic waste products of anaerobic bacteria and eliminate rank odors in the cutting oil. The cutting oil is aerated to encourage the proliferation of the aerobic bacteria, and to discourage the proliferation of the unwanted anaerobic bacteria.
Claims13
An apparatus for the remediation of an anaerobically fouled cutting oil, said apparatus comprising:
- (a) a housing comprising two chambers which is removably insertable into said cutting oil, said housing comprising:
- (i) an aeration chamber, said aeration chamber having a plurality of openings for the escape of air bubbles into the surrounding cutting oil;
- and
- (ii) a bacterial support chamber, said chamber supporting cultured aerobic bacteria on an inorganic particulate substrate therein, and said chamber permitting flow of the surrounding cutting oil into and out of the bacterial support chamber;
- and
- (b) an air compressor means for continuously providing air to said aeration chamber.
An apparatus for the remediation of an anaerobically fouled cutting oil, said apparatus comprising a two-chambered housing which is removably placed within a cutting oil reservoir and which is connectable to an air source, said housing comprising:
- (a) an aeration chamber, said aeration chamber having a plurality of openings for the escape of air bubbles into cutting oil;
- and
- (b) a bacterial support chamber, said chamber supporting aerobic bacteria on a surface therein, said chamber permitting flow of cutting oil into and out of the bacterial support chamber.
