BDP® Waste Sludge Reactivation and Recycling Project Menifee, CA

• Project Overview: Implementation of BDP technology for the reactivation of

waste sludge in order to reduce bad odor for Menifee Lake

residents and communities.

• Total Project Duration: 4 Months BDP performance results could be seen after 1 month of

operation.

Reactivated sludge was recycled back into the wastewater

treatment facility, providing healthier activated sludge to the

treatment tanks for future treatment needs.

After one month of operation all complaints of foul odors

were resolved.

Higher concentrations of healthy activated sludge in the

activated treatment tank resulted in better discharge effluent

quality and lowered operation costs.

Plant has been active since March 2016.

BDP ® - Non-stop and Simple Maintenance

Non-Stop Maintenance Anti-clogging Operation System Non-Stop Diffuser Replacement System

• Non-Stop Maintenance Anti-clogging Operation System

Aeration system is installed with a “self-cleaning” function, by which the foulants can be

dislodged easily.

• Non-Stop Diffuser Replacement System

A single diffuser is changeable within 10 minutes, without interfering with WWTP operation.
