No Chemicals. No Sludge.

Nantra™ will treat surface water with up to 3000 NTU turbidity without coagulation or other pre-treatment. Colour and DOC are reduced by up to 90%. There is nothing added to the reject streams of either process allowing the residuals to be returned directly to the environment. It, in effect, removed the water from the river, lake or dam, leaving the contaminates behind.

  • NO Sludges to deal with 
  • NO Chemical storage or handling 
  • NO Jar testing 
  • Fully automated with Nantra™ Smart IT 
  • Simplified Instrumentation and operation 
  • Low energy consumption 
  • High rejection of suspended solids and organic matter 
  • Good removal of pesticides and herbicides

Explore The Nantra Series


NantraDOC™ is a low energy membrane operating at less than 1.5 Bar without high recirculation. In the Nantra™ process, we protect the NantraDOC™ membranes with the most advanced solids and turbidity removal membrane process on the market, NantraUF™, which incorporates Koch Membrane Systems’ Puron MP membranes.

Akvotek’s NantraUF™ incorporates these membranes in a unique package with advanced control systems that virtually eliminate the need for operation of the plants.

The NantraDOC™ membrane is unique to Akvotek. It is neither a nanofiltration nor an ultrafiltration membrane, but has the most desirable of the properties of both when it comes to water treatment without the disadvantages normally associated with the use of these technologies. The system is specifically designed to remove organic compounds while minimising the removal of divalent ions that can result in reduction in alkalinity and increase ins corrosion potential.

Nantra™ S Series

Simple, reliable and operator friendly, the Nantra™ S Series has one small pump and all valves are identical reducing inventory and servicing requirements.

These units will deliver up to 100,000 L/d of treated water and can be operated on solar power or a single phase household power supply.

Nantra™ Q Series

NantraTM Q is for large scale installations. To keep it affordable these systems are optimised based on value for volume produced. The control system adjusts based on the internal performance of the plant and ensures that the balance of recovery, pressure and flow are optimised to give the community high quality water with low energy consumption.
