SolarBee offers an economical, environmental friendly and green solution for natural or artificial fresh water bodies, oxbows and drinking water reservoirs. The SolarBee is uniquely capable of :

  • eliminating cyanobacteria (blue-green algae) blooms,
  • oxygenating lake bottom waters and sediments to prevent release of hydrogen sulfide, iron, manganese, and phosphorus,
  • preventing seasonal fish kills,
  • reducing nuisance aquatic weed growth without either toxic chemicals or fossil fuel consumption.
  • By ensuring high dissolved oxygen values in every segment of the water, SolarBee makes healthier conditions for aquatic life. According to experiences in the following years SolarBee had been installed fish spawning can be 20 times the rate it was before.

In fresh water lakes and reservoirs, the SolarBee can be deployed in two different methods regarding hose settings and spacing: (a) for blue-green algae and invasive macrophyte control or (b) for hypolimnetic aeration.

  1. When deployed for blue-green algae control, the SolarBee prevents phosphorus and nitrogen from being turned into inedible blue-green algae blooms that can cause toxic conditions. Instead the SolarBee mixing causes nutrients to be uptaken by “good” planktonic organisms which are then eaten by zooplankton which in turn are eaten by fish. Since the nutrients are being pushed through the food chain, controlling the levels of phosphorus and nitrogen becomes less important, and the lake become highly productive while at the same time water clarity and odor improves, dissolved oxygen (DO) increases, pH and chlorophyll a decline, diversity increases, and fish become more vigorous. We have also seen increased fish spawning rates, up to 20 times higher, than before SolarBees were installed. Another benefit appears to be a slow reduction of invasive weed species as the blue-green algae is eliminated. Another benefit may be mosquito control. PSI is conducting testing to determine the mechanisms behind all of the effects of SolarBees on the epilimnion of lakes.
  2. When deployed for hypolimnetic aeration, the SolarBee can transport oxygen down to the sediments to prevent the release of manganese, iron, H2S, and phosphorus. This is accomplished without disturbing the sediment or de-stratifying the lake, so that the cold water fishery is preserved. We have found, in most cases, that by controlling the blue-green algae in the epilimnion the oxygen demand on the sediment is reduced enough to minimize anoxic conditions in the hypolimnion.

Maintenance and service requirements of the SolarBee machines are minimal, and it consumes virtually no grid power for it’s operation.

In addition, the SolarBee is economical for virtually any size of lake or reservoir, requires no infrastructure changes, and can be installed on a rental basis until satisfactory results are proven.
