The wastewater from a small section of a southwestern U.S. city was studied. Concerns of grease accumulation and the increasing cost of operation year after year of a current odor control chemistry gave rise to searching for a better solution. There was evidence that grease and slime layers within the pipes and lift station were increasing with the current chemical solution. The city substituted a novel Bio-organic Catalyst (BOC), manufactured by Neozyme International. Inc.. for the current chemistry in one lift station and studied the results through subjective daily observations. The results indicated a complete control of odor and an elimination of slime and grease.
Key words: grease, sewer, odor, bio-organic catalyst, hydrogen sulfide, dissolved oxygen.
