Covered Ponds

Covering ponds with translucent membranes or the use of greenhouses overcomes this problem, allowing the more productive strains to be grown free of atmospheric contamination.

In raceway ponds, large contaminants can be removed regularly by placing a suitably sized screen in the water flow. Heavy contaminants that sink to the bottom can be trapped in pits arranged at right angle to the flow and can then be removed from these sediment traps.
