Task: Supplying labwater for a research institute in which consumption differs significantly.

Solution: Redundant AquaRO systems producing 2 x 200 l/d. The frequency controlled double pump station ensures that a continuous recirculation with minimized energy input can is achieved. The second system starts depending on time or on the remaining volume in the reservoirs.

Task: Supply of labwater to laboratories and steam production

Solution: Combined RO/EDI system. Reverse osmosis produces 3500 l/h at < 10 µS/cm to feed the steam production and an EDI-component, which produces 1000 l/h at < 0,5 µS/cm. The RO permeate is stored in a separate reservoir. The sensor controlled duplex softener protects the whole equipment from fluctuations in the drinking water quality.

Task: Local DI water supply at a conductivity below 0,5 µS/cm consuming minimum space

Solution: EDI compact producing 20 l/h feeding a 300l reservoir, minimized temperature increase using a frequency controlled booster pump. A UV system to insure low TOC-level. Complete unit is integrated into the lab furniture.

Task: High consumption of DI-water < 20 µS/cm and a significantly lower need of labwater.

Solution:Splitting of the 2 steps in an EDI-system. After passing the reverse osmosis step there is a tank that is filled with 1500 l/h. This water < 20 µS/cm is used to feed steam production and the autoclaves. It also feeds the EDI-component, that purifies 200 l/h labwater to < 1 µS/cm.·

Task: Production of DI water from drinking water , great variation in consumption

Solution: OPTIRO 15 feeding a 60 l pressure tank, where the DI-water is stored to cover the peak consumption.

The construction is simple, because further components like a booster pump, a level control, a venting system or a tank overflow are not needed. The pressure of this tank is sufficient to supply additional users. The stored volume can be adjusted to actual needs.
