HWT Bioreactor

Our classic design is a multi-chambered underground bioreactor arrangement.  This method of construction ensures that the treatment plant is almost completely hidden from view.  The HWT bioreactor has been used extensively at wineries and ENGEN One Stops.  Treated effluent is compliant with the DWS General Limit and this has been achieved via the Hydrossis Process.
