Cyanobacteria, Taste & Odor Control for Raw Water - Case Study
Dramatic decrease in taste & odor complaints, beneficial increase in biodiversity.
Topics: raw water, cyanobacteria, blue-green algae, cyanotoxins, taste and odor, algaecides
- Man-made drinking water impoundment fed by a feeder canal.
- Surface Area: 160 acres.
- Average Depth: 42 feet.
- Max Depth: 79 feet.
Pre-Deployment Conditions: Frequent applications of algaecides were needed to control cyanobacteria. The Customer also experienced floating algal mats and numerous taste & odor complaints per day during the peak season.
Project Objectives: Control harmful cyanobacteria blooms and associated taste & odor issues via epilimnetic circulation.
Solution: Five (5) SolarBee Lake Circulators (2017).
Results: No algaecides have been needed since the SolarBee installation. If this continues through 2019, the entire project will be paid for with algaecide cost savings.
The Customer only had one (1) taste & odor complaint the entire 2018 cyanobacteria season and this report was minor at best.
No floating algae mats were observed in 2018.
Cyanobacteria peaks are trending less each year. They are seeing more zooplankton, diatoms and other good forms of good green algae. The reservoir’s fish population is reported to be very robust.
