Odor Control

Cover Ball offers a simple and quick solution against the problem of odors and harmful gas fumes deriving from the collection basins of livestock/industrial wastewater. Once placed inside the storage tank, the spheres arrange themselves over the entire surface, covering up to 91% of the entire area and reducing evaporation by up to 90%.

Subject to the best available techniques described in the European BAT, it is a floating cover system suitable for all surfaces, but even more, for all those collection basins of zootechnical and industrial waste which, due to their size, cannot use other cover systems for the reduction of emissions into the atmosphere.

Odor is a sensation resulting from the interaction of volatile chemical species inhaled through the nose, including among these sulfur compounds (sulphides, mercaptans), nitrogen compounds (NH 3, amines) and other volatile organic compounds (esters, acids, aldehydes, ketones, alcohols).

Cover Ball offers a quick solution, free of maintenance and any replenishment, for the reduction of odors deriving from storage of processing water:

  • Animal waste processing industry
  • Landfills
  • Farms
  • Oil & Gas industry (storage park)
  • Paper industry
  • Composting activity
  • Liquid wastewater treatment plants

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
