A Modern Solution - Sewage Treatment Plant

All sewage treatment plants are based on the same principle: to create the right environment for aerobic bacteria to be produced. The addition or presence of air creates microorganisms to break down the sewage within various treatment and settlement zones. The effluent quality from most leading manufacturers is 95 % or above clean effluent through the various stages of sewage treatment. Infinity Environmental are installers of all leading brands of package sewage treatment plants to the latest standard EN 12566-part 3. As independent installers we recommend the best product on the market to resolve your off mains drainage problem.
