Next to pre-,treatment, one can perform a chemical dosage (,acid,, anti-scalent), to prevent scaling and precipitation of insoluble solids, such as calcium carbonate and barium sulphate on the ,membrane, surface. The applied acids are hydrochloric ,acid, (HCl) and sulphuric ,acid, (H 2 SO 4). Sulphuric ,acid, is the most widely used chemical for this purpose.

Preconcentration can be done by RO, ED/EDR (electrodialysis), FO (forced osmosis) or MD (membrane distillation). 8. MD (membrane distillation) uses the different vapor pressure between both ends of the membrane allowing heat and mass transfer of the volatile solution components, such as water. It is a relatively simple method that can use waste heat.
