Making process and waste water reusable within the plant; lowers water cost and discharge load together.
Water recovery is the reuse of treated process or waste water within the plant instead of discharging it. It reduces two items at once: the volume of water purchased and the volume of waste water discharged.
The recovery configuration depends on which process the water will return to. The quality expectations of cooling tower make-up water and boiler feedwater are not the same; no stage can be selected before the intended use is known.
Which stream will be recovered and at what flow rate is established.
The stream’s contamination profile is determined; the recovery target becomes clear.
The water is brought to the target quality with filtration, UF and, where needed, RO.
The recovered water is fed to the designated process; the concentrate is managed.
Using the recovered water as tower make-up.
Feeding back into non-production utility lines.
Returning water of suitable quality to the production line.
Lowering the waste water volume and the cost tied to it.
The most frequently overlooked subject in recovery projects is the concentrate. As the recovery rate rises, what remains becomes smaller in volume but more heavily loaded; discharging it is a separate engineering problem.
That is why we set the recovery rate not at the highest possible figure but at the figure that is sustainable together with concentrate management.
It depends on your unit water cost, your discharge cost and the flow rate to be recovered; we make that calculation specific to the plant as part of the efficiency work.
Technically most streams can be, but it is not always economical. After characterisation we select together which stream is worth recovering.
Frequently yes. An existing treatment outlet is assessed as the feedwater for the recovery line.
