Gandras Energoefektas

JSC “GANDRAS ENERGOEFEKTAS” supplies air diffusers for aeration systems, and also can design new one or make reconstruction of existing aeration system.

• Waste water treatment plant (aeration basins, silt storage tanks, balancing tanks, etc.)
• Fish industry (air supply to the ponds, aquariums)
• Preservation of the environment (lakes, rivers, harbours recovery)
• Beer / wine industry (to increase oxygen content in the wort and must for barmes multiplication and fermentation beginning)
• Other

Coarse bubble air diffusers   Positive air pressure opens the valve allowing forward flow. Reverse differential pressure seals the bills, preventing backflow into the manifold piping. The patented “duckbill” check valve design eliminates clogging of air manifolds, saving end users thousands of dollars in maintenance and repair costs. The all-elastomer construction is flexible and non-fouling; making them suited for long-term, maintenance free service.

Fine bubble air diffuser

At the heart of the diffuser is an integral check valve that prevents backflow of sludge and debris into the air diffuser manifold piping. The diffuser virtually eliminates clogging and ensures maximum efficiency.
