The Clenviro MATRIX CLF1 Sewage Treatment Plant provides an extremely safe, efficient, reliable and cost effective solution to sewage disposal. All MATRIX sewage treatment systems meet and exceed all Environment Agency and regulatory requirements for process efficiency and final effluent quality. There are no mechanical components within the treatment plant itself thereby ensuring that maintenance is minimal, simple and safe.


The MATRIX treatment system is a three stage biological process contained within a single tank structure, based on the principles of a submerged bed reactor and designed in accordance with the requirements of BS6297. As part of the test procedure the MATRIX system was proven to have one of the lowest operating costs of all sewage treatment systems. Furthermore, all Matrix systems are complete with failure alarms as standard (as required by BSEN12566-3).
