The third generation rotating biological contactor (RBC) technology has arrived in the UK.

Wastewater treatment specialist WPL has brought a highly efficient rotating biological contractor to the UK municipal market. 

This third generation RBC technology with Its flexible modular design, means that it can be configured to serve communities ranging from 250 upwards population equivalent.

How it works

Repetitive rotation allows the discs to accumulate micro-organisms, which use the available oxygen to convert the pollutants in the wastewater into carbon dioxide and water.

  • The discs rotate faster
  • The innovative design has turned the traditional disc system around by 90 degrees, so that the flow runs through the rotating discs rather than along them.
  • This increases the surface area of media per square metre and the contact time between the bacteria and the settled sewage, increasing the efficiencies of the process
  • The WPL Miranda RBC has been designed to focus on the lowest possible whole life costs

The result is final treated effluent which exceeds the EU standards for discharge and can be safely released into the environment.

Save energy

Because of the modular design it is possible to bypass specified modules to reduce capacity and save energy. The packaged units are easy to transport and install – reducing onsite health and safety risks – and can operate in series or in parallel.

The WPL Miranda RBC has been available internationally since 2010, but an exclusive UK distribution agreement was recently signed with WPL.
