IDEA
SBR wastewater treatment plants normally use a control unit and a valve module. These are installed separately and have to be connected using costly cables and connectors. The BonBloc® compact integrates both, the controller and the valves into a single compact and easy to install device. No more cable spaghetti! The unit is equipped with a reduced set of features than its bigger brother, the BonBloc®. Nevertheless it offers all the comfort you need for most of the applications at a very competitive price.
VALVES
Instead of conventional solenoid valves we use reliable stepper motors from the automotive industry. These new valves have been successfully tested since 2008 in real waste water treatment plants.Why stepper motors? First, they consume energy only during opening or closing of the valve, therefore saving 95% of energy when compared to conventional valves. That is about 90kWh per year or 15€, and the trend is rising. Secondly, our valves are, due to the smoother and slower movement, much quieter than solenoid actuated valves of other sewage treatment plant controllers.
CONTROL UNIT
Three buttons, three LEDs, an alphanumeric LCD display - regarding its operability our BonBloc® compact control unit for decentralized wastewater treatment plants leaves nothing to be desired. The device can be equipped with pressure and current sensing to monitor the compressor. Using the digital inputs up to three float switches or other signal sources can be connected (depending on equipment version). Up to four reliable relays can control the compressor and other devices (e.g. UV-lamp, dosing of chemicals). The GSM-module will reliably send SMS if any alarm occurs. The BonBloc® compact compact can even be remotely controlled and recalled by GSM. The BonBloc® compact control unit is also equipped with features, such as acoustic signaling of predefined conditions, a sequence program permanently saved in the EEPROM and a set of NiMH rechargeable batteries (or normal batteries) to ensure continuous signaling during power outage or the function of the GSM-module. All electrical connections are implemented using cost-effective and universally compatible screw type terminals.
