Product Description

Odor control covers for sludge tanks and clarifier tanks

Our odor control covers are designed to minimized odors and gaseous pollutants, as well as suited to cover pre-tanks and post digestion tanks. 

M1 Cone are suited to cover pre-tanks and post digestion tanks. They can be designed to cover the tank for odor containment and rainfall protection or even to be gas tight and to serve as gas storage.

Claricover is a new and unique solution to cover the primary and secondary clarifier tanks of the waste water treatment plants. They consists of a main supporting structure in stainless steel, a side membrane wall made in polyester PVC coated fabric, a permeable inner membrane, an air cover pressurization system as well as an entrance box that works as a pressure compensation chamber.

FLC Membrane covers are custom designed to minimize odors and gaseous pollutants, and avoid evaporation and diffusion into the atmosphere caused by wind action. The covers are made with flexible sheets of closed cell poly-ethylene foam that is resistant to acids and weathering. Its covers are installed on existing and new construction tanks of any size and shape. Their main advantage is that they mostly eliminate odors from manure storage tanks, and industrial storage plants.
