Domestic wastewater treatment plant
AS-VARIOCOMP K ULTRA Asio

The treatment plant is designed in such a way that despite a small entrance, all equipment is well accessible and removable from the tank without necessity to empty the tank. With regard to its life period, it is recommended to place the blower in a building or a shaft outside the treatment plant. In case of leaving e.g. for holiday, it is easy to secure recirculation of water in the plant so that biology is supplied with nutrients from secondary settlement tank. Sampling can also be easily done considering placement of sampling point and design of outlet pipe. The plant may also be delivered with equipment for skimming floating sludge in the secondary settlement tank, and in case of need to remove phosphorus, a dosing device for coagulation agent may also be delivered. The operator is then responsible just for disposal of sludge and adapting the operation of the plant to local conditions consisting in setting the amount of excess sludge to be drawn off.
Service work is done by an authorised service company.
Maintenance of membranes and setting of how much excess sludge shall be drawn off is done so that in agreed in principle half-a-year intervals, the membrane module is exchanged for a new one and the current one is regenerated by a service company. During this operation, evaluation of amount of excess sludge is also carried out and draw-off mechanism is adjusted.
