A Single Source Supplier

Our broad range of water and wastewater treatment systems enables you to access one or multiple technologies for integration into a total water treatment solution specific to your feedwater source and application.

Global Sourcing

As a designer, manufacturer and supplier of water and wastewater treatment systems and services worldwide, we have developed a global sourcing network that can deliver maximum value through the elimination of non-value-added expense.

Flexible OEM/ODM Service

We believe that standard products are not always able to meet our customer’s demands.  To best service those needs, ROtek has an extensive OEM/ODM service where you can access our custom design service and see the project through to production with the help of our specialised  team.


ROtek use only the best available components in all our systems to ensure long operating life and reliability.  Wherever possible we use globally supported components in industry standard formats to give maximum choice of using new developments in membrane and filtration technologies as they become available.  We have developed a specialised surface modified reverse osmosis membrane for groundwater treatment as part of our ongoing development process and continue our research to improve all ROtek systems to give you the best possible solution.


ROtek water treatment systems are designed with a minimal footprint to ease installation space.  Systems are fully engineered with corrosion resistant stainless steel frames, high pressure rigid pipework, stainless steel braided flexible hose and high pressure membrane pressure vessels.


ROtek reverse osmosis systems provide the highest efficiency possible for conversion rates and power consumption.  Larger systems may be fitted with variable speed controllers for the high pressure pump to reduce energy consumption
