Pure water is used in the make-up of liquid soap and therefore reverse osmosis (RO) or deionised (DI) water quality is required depending on the desired result.

When making lotions and shampoos, muslin was traditionally used as filtration, however this is replaced by bag filtration in production as a high surface area option with greater efficiency. Bag filtration is used in the early stages to remove large deposits of unmixed product and anything that could produce an uneven finish. These are typically housed in stainless steel housings due to the flows, pressures and cleaning regimes involved.

Stages of Filtration & Water Treatment

RO Water Production

Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.

DI Water Production

The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.

Bulk Solids Removal

To remove a high quantity of solids, gels and other irregular shaped particles, a filtration solution with high surface area and flow properties is required.
