Problem: The facultative lagoon treatment system in Othello, Washington, had problems consistently meeting BOD and TSS permit requirements.
Solution: The city worked with EnBiorganic Technologies to implement the EBS-Di bioaugmentation system, which introduces organic bacillus soil bacteria into the wastewater treatment process. The additive is dosed with a continuous and automated approach.
Result: The process is expected to improve treatment efficiency and ensure compliance. “This trial enables us to see what impact the EBS-Di system will have,” says Shawn O’Brien, city engineer. “We hope it will improve our ability to meet our discharge requirements in all seasons.”. 888-356-8333; www.enbiorganic.com
