The effective treatment of distillery wastewater has always been important, particularly at locations which require the removal of copper. Many distilleries operate with old technologies and some with limited treatment. There are new treatment technologies, based on aerobic, anaerobic and membrane processes, which are of great interest to the industry.
Wee offered a membrane bioreactor (MBR) process and was able to design a system that fully integrated into the distillery along with new pre-treatment facilities. The crossflow MBR process offered a number of distinct advantages, compared to the old bio-filtration processes, including reliable and enhanced treatment performance, which ensured good treated water quality. 

DM (demineralised) water plants are systems used to carry out industrial water treatment. To be more precise, the DM plant remove dissolved solids or minerals from process streams and feed water. These plants remove minerals using any one of the following procedures:

•  Deionisation
•  Distillation
•  Electrodialysis
•  Membrane filtration (nanofiltration or reverse osmosis)

Demineralised water or deionised water is water devoid of its mineral ions. Water in its natural form typically contains mineral ions like anions (sulphate, chloride, nitrate, etc.) and cations (iron, calcium, sodium, copper, etc.).

The main purpose for which a DM plant is used is preventing metal oxidation and scale formation.
