Wastewater Treatment Case Studies
Wastewater Lagoon Treatment Case Studies
Case Study #1
Sludge: Sludge removal cost for cells 1 & 2 was $300,000.00+. Our lagoon program reduced sludge levels by 25% in year 1,saving $75,000.00 in removal costs.
H2S/Odor: This wastewater treatment lagoon averaged six odor complaints per year. After the program took full effect, there were 0 complaints.
Aeration costs: To help increase their dissolved oxygen numbers, two aerators were in use with a cost of $1,500.00 per month, plus man hours for maintenance and repair. Three months into our lagoon program, dissolved oxygen numbers increased, and the aerators were retired.

Case Study #2
Sludge: removal cost was 25% greater than average due to high metal content in the sludge. The sludge levels see 10% reduction annually each year it was measured with the Clearbrooke Technologies proactive pretreatment program.
Odor Control: Before our program, the customer had extensive odor from Cell #1 and the main lift station in town. After one week, all odors vanished and there was no odor from spring turn-over.
