BonBloc compact

• Outstanding price-performance ratio due to the integrated design and absence of 230V solenoid valves
• Up to two water levels can be evaluated by pressure sensing
• Easy to install and connect
• Quiet valve operation
• Saves approximately 95% energy compared to units using standard solenoid valves
• Up to 4 relay outputs offer a comfortable connection of accessory devices
• Processes can be easily created and modified using Excel^® table
• Password protected system - menu provides access to manual control and easy changing of step times
• IP54 casing, optionally UV-resistant for outdoor installation
   

SBR wastewater treatment plants normally use a Control Unit and a valve module. These are installed separately and must be connected using costly cables and connectors.
The BonBloc^® compact integrates both the Control Unit and the valves into a single compact and easy to install device. A economic solution with no more cable cutter and all the comfort you need!

Valves

Instead of conventional solenoid valves the BonBloc^® compact uses reliable stepper motors from the automotive industry. The main benefits of the stepper motors are up to 95% energy savings and that they are much quieter than solenoid actuated valves.

Water-level sensing by pressure measurement

The BonBloc^® compact is equipped with a pressure sensor and an evaluation logic to determine the water level during aeration or pumping. This level sensing can be used instead of failure-prone and costly float-switches.

Control Unit

Three buttons, three LEDs and an alphanumeric LCD display - regarding its operability our BonBloc^® compact leaves nothing to be desired. The device is equipped with pressure 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 2G/4G-module will send SMS if any alarm occurs. The BonBloc^® compact can even be remotely controlled and recalled by the module.

The BonBloc^® compact 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 to ensure continuous signaling during power outage or the function of the 2G/4G-module.
All electrical connections are implemented using cost-effective and universally compatible screw type terminals.

Generally, the Control Units are delivered with a menu, web pages and a process, which were developed according to the requirements of a sewage treatment plant manufacturer. As the development is time-consuming and thus not efficient at low quantities, BONNEL offers some standard processes which can be slightly modified according to customer requirements to lower the development costs. Please mind, that there are only dummy step times programmed. The preprogrammed processes do not replace know-how about decentralized sewage treatment at BONNEL’s customers. BONNEL is a market leader in control units, not in sewage treatment processes. BONNEL does not guarantee that plants with these standard processes will have good treatment results. BONNEL does not copy any processes or features that have been realized for a customer into its standard processes.

Currently, the following standard processes are available:

Air-SBR

• Eco-Mode via Filling airlift
• Eco-Mode and Overfill Alarm via float switch
• No Eco-Mode, optional Overfill Alarm via Float switch
  
   

Standard models are available in any quantity. Besides the standard models, customer specific versions / configurations are available at a MOQ of 100 units per year. For the Order Reference, please consult Order Reference table for standard models.

For customer specific models (MOQ 100pcs p.a.) please inquire according to the the Order Reference table for customer specific models.
