Algae growing in any aerated lagoon systems, ponds or wastewater treatment plants can and often will increase both the TSS and the CBOD5 of the effluent. This can cause BOD and TSS levels to rise over the effluent permits and result in unwanted fines. Excess algae can also create nuisance surface scum, poor water clarity, and noxious odors.
Not all algae are alike though. Algae or cyanobacteria and tetrads that grow in wastewater ponds and lagoons are often times due to an excess of BOD instead of excess nutrient levels. Algae fix nitrogen from the sunlight and will quickly overtake the lagoons and cause serious TSS problems.
Modular floating pond covers can provide an efficient way to block sunlight, will adapt to complex contours and changes in water levels while providing open surfaces for most aerators (mechanical, diffuser, etc…).
Installing a pond cover such as the Armor Ball® cover (91% coverage) or the Hexprotect® AQUA cover (99% coverage) will block sunlight and eliminate algae formation. TSS and BOD levels will drop. Additionally, our modular covers will also camouflage the pond, make it less attractive to waterfowl and reduce fecal coliform count from animal waste.
Covering a lagoon has many added benefits besides eliminating algae growth.
All our covers offer substantial advantage over solid covers:
