Abstract
Methods of using cleaning compositions for reducing fat, oil, and grease (FOG) and enhancing soil removal for improved FOG discharge are disclosed. Cleaning compositions comprising a demulsifier, an alkalinity source and at least one additional functional ingredients to effectively destabilize FOG in a waste water source, a discharge, drain, grease trap or grease interceptor, or the like are provided. Methods of using the compositions to substantially decrease FOG discharges into water sources with or without the use of drain cleaners are also provided.
Claims20
A method of reducing fat, oil, and grease discharge comprising:
- adding a demulsifier to a cleaning composition to form a use solution to contact the demulsifier with a source of fat, oil and grease;
- contacting the use solution with the demulsifier and cleaning composition with the source of fat, oil and grease for a sufficient amount of time to destabilize the fat, oil and grease in a waste water source, wherein the sufficient amount of time is at least about 10 minutes;
- and
- decreasing the fat, oil and grease discharge from the waste water source to less than or equal to about 250 ppm (mg/L);
- wherein the demulsifier comprises a capped block copolymer, a reverse EO/PO block copolymer, an alkyl capped alcohol ethoxylate, an alkyl pyrrolidone, a silicone polyol and/or silicone polyether;
- and
- wherein the cleaning composition comprises an emulsifying surfactant;
- and
- wherein the use solution comprises from about 10 ppm (mg/L) to about 100,000 ppm (mg/L) of the demulsifier.
A method of using a demulsifier to destabilize fat, oil and grease in a water source comprising:
- contacting a water source with fat, oil, and grease with between about 10 ppm (mg/L) to about 100,000 ppm (mg/L) of a demulsifier to form a treated water source;
- wherein the contacting provides a dwell time of at least about 10 minutes that is a sufficient amount of time to destabilize the fat, oil, and grease;
- and
- reducing the fat, oil, and grease discharged with the treated water source to less than or equal to about 250 ppm (mg/L);
- wherein the demulsifier comprises a capped block copolymer, a reverse EO/PO block copolymer, an alkyl capped alcohol ethoxylate, an alkyl pyrrolidone, a silicone polyol and/or silicone polyether.
A composition for reducing fat, oil, and grease discharge comprising:
- a demulsifier comprising a capped block copolymer, a reverse EO/PO block copolymer, an alkyl capped alcohol ethoxylate, an alkyl pyrrolidone, a silicone polyol and/or silicone polyether;
- an alkalinity source;
- and
- at least one additional functional ingredient,
- wherein the composition is a liquid or solid.
