“i-DOSE” system to comply with this real-time control process for chemical treatment of wastewater, significantly reducing wastewater operational costs (e.g. chemicals, aeration, energy). The system also allows facilities to be operated at a maximum performance with reduced operator’s presence due to the intelligent dosing philosophy. As well as our existing and proven i-DOSE pre-treatment applications, i-DOSE can also be applied within secondary and tertiary water and wastewater treatments.
