All processes and conditions in the SBR treatment plant are continually monitored so that at any time an accurate overview of the process can be made. The IT systems supplied by HST can provide, on request, information on any deviations and can initiate all necessary inputs to control the treatment process. The use of settling additives can be eliminated or reduced thanks to better Bio-P-elements. This leads to reduced operating costs and better protection of the environment. We have combined the various components of an SBR plant to a fully functioning composite unit.
