According to BONNEL's intention to be a one-stop-supplier for all electronics around decentralized and domestic wastewater treatment plants, we have developed useful accessories for control units.

Currently we can offer you:

• BonFlash strobe beacon: These handy alarm beacons can be powered out of the rechargeable batteries of our control units for decentralized sewage treatment plants. Like this you have an alarm at mains failure and do not have to care about recharging batteries. Versions with batteries and rechargeable batteries inside the control unit are available, as well.
• BonRelay contactor relay: Used to connect higher loads to the outputs of our control units for wastewater treatment plants.
• Memory keys to transfer software, electronic operating books and event logs to / from our Sequetrol^® control unit for decentralized wastewater treatment.

BONNEL offers a wide range of control units for SBR sewage treatment plants for both, submersible-pump operated plants and plants using airlifts. From the low-budget Sequetrol^® compact LED up to the powerful Sequetrol^® IoT with graphical LCD, Wi-Fi, integrated webserver and GSM - all SBR applications should be covered.

All SBR control units can handle Eco- and Normal modes, most of the control units support water level measurement by pressure sensing, so a float switch is not necessary anymore.

The Sequetrol^® control units are easy to program, programming can be done by yourself or BONNEL can support you.

The BonBloc^® series control units for decentralized sewage treatment plants was developed, to meet the following customer requirements:

• enhance cost efficiency - integrated design
• BonBloc^® = (control unit + valves + water level sensing) in one unit
• reduce noise and energy consumption - stepper motor valves
• ease installation - easy to install due to an intelligent mounting

It stands out due to its cost-efficient integration of the control and the valve unit. As a result of the complete abandonment of solenoid valves, the energy consumption of the valve unit was reduced by 95% compared to units using standard valves. 

The BonBloc^® control units, especially the BonBloc^® compact, are easy to program, programming can be done by yourself or BONNEL can support you.

BONNEL offers a wide range of control units, valve manifolds and accessories for decentralized sewage treatment plants.

We do not offer standard products, such as PLCs adapted for sewage treatment plants, but all our control units and devices are developed with respect to the special requirements of decentralized wastewater treatment. All products are a result of the feedback from our customers and many years of experience supplying control units and accessories all over the world.

Some of the technologies invented or optimized by BONNEL are now industrial standard at small and medium-size sewage treatment plants. Here are some examples:

• Stepper motor technology for silent, energy-saving and reliable valves
• Water-level measurement by pressure sensing through diffusor or airlift of an decentralized sewage treatment plant
• Blower power measurement to monitor blower pressure
• Wireless float switch without batteries

Why to use control units for decentralized sewage treatment?

Benefits for manufacturers

• Prove that your wastewater treatment plant is working well: Operating hours counter, alarm hours counter, pressure / current monitoring, mains failure alarm, service alarm
• Design more robust sewage treatment plants: No inaccurate manual valves, easier adoption to different site conditions, alarms
• Design more attractive sewage treatment plants: Beautiful “face” for your plant, “cool” technologies like SMS monitoring and operation. 
• Ease servicing: User guidance, clear text alarm messages, objective parameter setting, shorter servicing (no manual backwash)

Some background about our control units in general

Our control units are developed and manufactured in our production plant in the Czech Republic. Those are self-developed PLCs, that are optimized for the use in decentralized sewage treatment plants. Therefore, they are free programmable, but “prepared” for a lot of tasks you’ll have to solve frequently in wwtp. For example water level measurement by pressure sensing using the diffusor or the airlift, is already prepared. The menu structure is also programmable, but things like manual operation, operating hours counters and similar are easy to realize. Mostly BONNEL implements the programs according to customer’s requirements, but you can do it on your own or modify our suggestion with our free, graphic programming tools.
Our integrated valve units are designed to replace the common solenoid valves. They use reliable stepper motors from automobile industry instead of solenoids. The benefits are a lower price, an integrated solution, a smooth operation without noise and the saving of 10W during operation, which is about 1/7th of the total energy consumption of a 4PE/IE plant.

BONNEL - always one step ahead!
