Algae control

The main causes of algae formation in water basins are exposure to the sun and temperature.
Algae growing in drinking water tanks or an aerated lagoon system increases both the TSS and CBOD5 of the effluent, deteriorating the taste of the water, risking filtration systems becoming clogged, increasing the cost of necessary chemical treatment.
Because algae reduce water quality and play no beneficial role in drinking water and wastewater lagoons, preventing their growth is important for systems to function properly.

Cover Ball reduces the surface exposed to UV rays by up to 91%, reducing the formation of algae and the passage of sunlight and therefore photosynthesis. This type of floating cover is used to shade tanks and lagoons, even aerated ones. In the case of the latter, the coverage must be sized so as not to cover the entire surface of the lagoon, especially in the presence of mechanical surface aerators where it is important to leave sufficient open space.

Cover Ball adapts to any shape and any change in water level providing perfectly adaptable surfaces for most aerators.

Technical Features

  • Easy installation. The spheres, once introduced into the tank, naturally assume an equal distribution over the area
  • Rain water. Unlike fixed roofs, the spheres allow rainwater to pass through. This allows you not to have any type of stagnation
  • No Maintenance. No type of maintenance or reintegration over time
  • The spheres follow the level of the liquid and allow any type of work inside the tank
  • The material with which they are built (HDPE – high density polyethylene) guarantees a long life to the cover
  • Virgin HDPE, therefore totally recyclable at the end of its life


  • Quick and easy installation
  • Each sphere is built to live a long time and free from "Biosphenol-A"
  • No type of maintenance
  • It allows any type of operation through the liquid
  • Fast and concrete solution against odor problems
  • Significant reduction of polluting gases
  • Reduction of UV exposure
  • Excellent deterrent against birds
  • Algae reduction
  • Wind resistant
  • Excellent behavior with frost, snow and rain water
  • Continuous coverage 365 days a year
