SolarBee Working

Reservoir Size:

3 ponds with acreage totaling 2.1 acres.

SolarBee Installation:

December 2000: Installed one (1) unit equal to SB2500* with 24-hour electrical kit into Pond 2 and a similar unit into Pond 3. March 2002: Installed one (1) unit equal to SB2500 with 24-hour electrical kit into Pond 1. December 2002: Units in all three ponds were upgraded to B10000s. September 2003: The SB10000s were replaced with the new SB10000-DM (duel mix) units.

Project Objectives:

Primary objectives were to solve the initial problems of high ammonia, some odors, high BOD, TSS,and energy consumption.

Project Results:

The first units installed in Pond 2 and 3 totally eliminated aerator run time in Pond 2, and reduced odors. After the 3rd machine was added to Pond 1 in March 2002, it brought up the next 8 months average pH to 8.36, and the average ammonia down to 9.83 mg/L for a 20% reduction. Electricity costs dropped from $14K to $4K (i.e., $10,000 savings) as the aerator in Pond 1 was reduced to 8-10 hours per day. After the duel mix units were installed in September 2003 and aeration timing corrected, great improvements were made in reaching effluent discharge limits and the SolarBees have met performance expectations since.
