Overview
Our planet’s water reserves are becoming more and more of a scarce resource. Water use for a series of domestic and industrial applications is governed by regulatory compliance requirements and numerous Health & Safety and Environmental (HSE) considerations. At the same time, disposal rules are also becoming increasingly stringent and pose demanding requirements which often require and dictate water treatment. On the other hand, water is priceless and irreplaceable. Every single drop needs to be managed carefully and sustainably.
Reverse Osmosis (RO) Desalination provides answers to all the above challenges.
