For biological treatment of sludge in fish farms, lakes and clarifiers but even in the sewers economically optimized and at the same procedurally flexible ventilation systems with maximum oxygen transfer efficiency and minimum energy consumption are required.

With our DANA ™ watermanagement system, a sludge removal can be achieved up to 80%. A dump of the water or a resettle of the animals is not necessary. The long life of our watermanagement system and the minimal energy consumption and the  control systems achieve a fast amortization.
