The service water should be nearly free of suspended material, nearly odourless, and will not stagnate within a 5-day period - Freewater guarantee these standards will be met.

Hygienic safety

The treated greywater flows through a UV-reactor before it comes to use. The UV-radiation disinfects the cleaned water. Should the plant malfunction, the photo-optical UV-control interrupts the flow into the storage tanks. The storage tanks are automatically replenished with drinking water to ensure a water supply for the consumer.

User comfort

The cleaned greywater is odourless, clear and free from suspended material. The user suffers no loss of comfort in comparison to the use of drinking water (see figure: UV Transmission Data).

Convenient maintenance

All units function automatically and are made of high-grade industrial components which do not require special maintenance. The micro fauna of the RBC regulates itself naturally, and the accumulated biological sludge is let off regularly. The pumps are controlled by pressure, and if necessary by the water current. The UV-reactor is run continuously. The maintenance consists of a regular plant control and simple cleaning activities which can be performed by the user.

System controls

Only components of the highest quality and reliability are used in the manufacture of the control systems: flotation switches, programmable timers and interval relays.
