- Subject: alternative for phosporic acid cleaners?
- From: "Ms. Tracy Wyhlidko" <email@example.com>
- Date: Tue, 06 Apr 1999 10:50:39 -0700Dear Mr. Barron, I attended your Janitorial Products seminar at the CWEA Industrial & Hazardous Waste Conference in Berkeley, CA on February 18, 1999. I am interested in a less toxic alternative for phosphoric acid scale remover. I am the Pretreatment Coordiator for the City of Eureka, CA. In our city we have a tortilla chip factory called Bien Padre Foods. Every Saturday Bien Padre removes the cooking oil from their tortilla chip fryer, cleans the fryer with a sodium hydroxide solution (pH 12), then cleans with a phosphoric acid solution (pH 2.0), rinses the fryer a few times, and adds the cooking oil back. Currently the facility does not blend the caustic and acid wastes prior to discharge to the sewer. I am looking into adding a waste blending requirement to their wastewater discharge permit, but I am also interested in alternative chemicals they could use. Can you recommend any alternatives to phosphoric acid scale remover that could be used in a food processing facility? If you also know alternatives to the sodium hydroxide that information would be helpful, but I am more concerned with the acid product at this time because our pH discharge limits in the City are 5-12.5. Thank you, Tracy Wyhlidko Pretreatment Coordinator City of Eureka (707) 441-4362 fax (707) 441-4366 email firstname.lastname@example.org
