Water supplied to factories and commercial buildings meets standards set by the World Health Organisation (WHO). This assures taste and hygienic condition but for many manufacturing processes there are additional requirements for purity, which have to be met by onsite treatment.

e-RPM delivers a comprehensive range of filtering, softening, deionising and sterilising equipment founded on unitised designs which can deliver water to the precise standard required.

Traditional methods of purification using ion exchange are increasingly being replaced by membrane based technologies which avoid the use of chemicals.

Processes include:

• Ultrafiltration for solids and colloid control
• Nanofiltration for hardness removal without added sodium
• Reverse osmosis for deionisation to less than 10 microsiemens quality
• Electrodeionisation to produce water up to 18 megohms resistivity
