In 2019, BONNEL will launch an new IoT control unit with integrated, stepper motor actuated valves, quiet and reliable in operation. Read more about BonBloc IoT soon!
Owners (private and public entities) and service staff can benefit from remote control and monitoring of the WWTP operation. BONNEL TECHNOLOGIE offers smart apps and advanced telemetry systems for this purpose. The IoT controllers have already been installed in many European countries. Moreover, BONNEL partners in countries, where decentralized wastewater treatment prevails, such as India, also implement IoT controllers in order to control and to supervise efficiently the treatment process worldwide.
Do you change your summer cottage for a mountain chalet in winter?
How can you adjust your sewage treatment plant for winter operation?
A biological SBR plant is already adjusted for this operation when it will be switched to an eco mode or even turned off from the inflow. Thanks to a control unit, the plant can be set up for winter months with a decreased inflow of effluent. It is necessary to keep the biological fuction of the plant. It means to protect live microorganisms in the tanks even without aeration and „feeding“.
Our partner TopolWater tested and operates its SBR plants with control units in demanding climatic conditions in Sweden and the company claims: „The operation has been tested under the conditions that a fully running plant was turned off from the inflow and after three months´ operation there was still 70 per cent of microorganisms present in the WWTP. According to the partner´s information from Sweden, even though the WWTP Topas 75 had been running 4 months in the winter time without any effluent, its biological function was preserved.“ www.topolwater.cz
At low temperatures technologies cannot freeze if they are in operation. If your plant is equipped with a control unit, our partner advises you to set up manually the operation which will make the wastewater circulate permanently and the blower will not switch off automatically.
Christmas season can mean a great load for your decentralized sewage treatment plant. WWTP manufacturers strongly recommend to avoid pouring the substances listed below into your plant.
They cannot be processed or even more they can be very harmful for your sewage treatment plant:
- strong lye (used in dishwashers), solvents
- chemicals and disinfectant liquids (concentrated or not biodegradable)
- sanitary items

Interview with Jan Bonn about the market trends in France
At the beginning of our interview with Mr. Jan Bonn, managing partner of BONNEL TECHNOLOGIE and professional in wastewater treatment (WWTP), we should be aware of the following facts:
At present there are 65 million inhabitants in France. In some regions without any sewage system, the French use decentralized sewage treatment. What is the current status in this branch?
Which types of decentralized sewage treatment plants can be found most frequently in France? Most frequently we can find biofilter sewage treatment plants or simple MBBR plants.
Which trends have you noticed during your October trip to the international fair in Dunkerque?
At the fair we noticed a great interest in monitoring of decentralized sewage treatment plants in particular regarding applications which have not been monitored until now. These are solutions with biofilter as well as simple MBBR plants. This monitoring should be ideally integrated into the "smart home" concept, the overall digital and long-distance monitoring of your home. In addition, applications for mobile devices, which enable to organize and optimize service trips more efficiently, were in focus.
Which trends has France followed in decentralized wastewater treatment recently?
In contrast to the Czech Republic or Germany, a solution based on biofilters is spread a lot in France. The fact is that in France their effluent values (= quality of water treatment) are often better than those of simple continuous sewage treatment plants without control unit. However, this solution is financially more demanding. MBBR plant manufacturers aim to offer intelligent concepts and control units which increase reliability and performance of these WWTP so that they can compete with biofilter-based plants.
How do biofilter producers respond?
This group of manufacturers tends to integrate monitoring and electronic solutions, which simplify the detection and analysis of failures, into their sewage treatment plants.
In which aspects do France and the Czech Republic differ significantly?
The Czech Statistical Office states that in 2016 the ration of sewage system coverage in the Czech Republic is 84.7%. In the capital city of Prague and in some regions, it is even higher than 90%. This ratio sets the conditions and regions where domestic sewage treatment plants can be used.
The overall situation in the Czech Republic and in France does not differ that much. The usage of decentralized WWTPs is limited in both countries by the fact that their types are tested only in testing institutions under laboratory conditions. For the real operation, often no explicit or neutral analyses of treated water are required. As a result, the end users do not obtain any information or overview which WWTP has which performance. The key factor for purchasing a WWTP is, therefore, its price.
The Czech Republic and France respond to this fact in a different way. The Czech Republic has announced an invitation to tenders which offers a subsidy program for decentralized WWTP under the condition that the municipality can prove that its WWTP has been cleaning wastewaters reliably for over 10 years. This approach is neutral, and it makes sense. A WWTP can reliably treat water for at least 10 – 20 years! However not all models. The cheapest ones often fail to do so in the day-to-day operation. Due to the financial possibilities from the subsidies and the project responsibility, municipalities have an opportunity to choose a WWPT which will provide a real contribution to environmental protection.
The French government subsidizes the WWTP types that have been proven successful on the French market and it means the subsidies go to WWTPs with a biofilter. At the first sight it is a logical but not neutral approach. In fact, it puts restraints on the development of quality technical WWTP which demonstrate good performance and excellent results of effluent water for example in Germany. In addition, compared to the WWTP with a biofilter they have a number of other advantages. In my opinion what makes a good functioning WWTP is its quality, intelligent design, suitable control units and service, not its type. Each customer / application case requires a tailor-made approach and some technologies are better suited in one case, some in another case.
BONNEL TECHNOLOGIE as a manufacturer of control units does not supply France directly. What are the advantages of working with a distribution partner?
The benefits are definitely their language knowledge, local market knowledge and options of service support. Our partner, the BIBUS company, offers control units made by BONNEL TECHNOLOGIE as well as SECOH blowers /air pumps, one of the most widely used high quality blower in the market. The BIBUS team has a wide portfolio of customers and they also demonstrate great know-how about systems of decentralized wastewater treatment.
Select the right battery – Ensure reliable operation of your control unit
The control units made by BONNEL TECHNOLOGIE, which monitor reliable operation of your decentralized sewage treatment plant, are complex electronic devices. In general, control units in continuous and SBR plants are exposed to demanding conditions. Among others the following operational parameters are crucial:
- Maximum temperature of WWTP ambience 50-55°C
- Batteries have to be of the right dimensions, capacity and type.
- Another criterion for their selection is re-charging through permanently low current.
BONNEL TECHNOLOGIE as a manufacturer of control units regularly checks and tests suitable battery types available on the market. Based on our experience we generally recommend:
- Type of the battery: Ni-MH
- Size: AA, HR6
- Capacity: ≥ 1800 mAh
- Execution: Suitable for permanent recharging with low current
Upon request with every control unit purchased we can supply 1 or more pieces of batteries.
You can buy the rechardable batteries in specialized shops, order them from your KKA supplier or from us.

How to take good care for your control unit
Do you have a family house, a weekend cottage or a challet? Do you have to deal with a location without a central sewage system?
Have you decided to benefit from modern decentralized sewage treatment plants which can enable you to re-use the treated water efficiently in your house for flushing the toilet or watering your garden?
Is a control unit part of your WWTP? Does it monitor its operation 24/7 and does it work in the eco and holiday modes? Does it prevent sludge from settling and smelling?
We asked BONNEL technicians how to keep your control unit – the brain of your WWTP – in the best shape for the longest time possible.
1. Install the device into suitable location.
Your control unit should be
- Outside your WWTP (or)
- In the well-aired space inside the WWTP
- Sufficiently high above the terrain to prevent a snowfall, flooding or dust from coming in
- In dry space – humidity can cause corrosion of electrical parts
- In a closed and well-aired object/box/pillar/wooden box. The blower will need fresh air not the air from WWTP.
- Inside, not in the direct sun. The control unit cannot be exposed to temperatures permanently exceeding 45-50 degrees Celsius. In the southern part of the control cabinet these values can be reached easily.
- Good access for the service staff and the owner
- No access for unauthorized persons and children
2. Check the control unit regularly – visually and by listening to it
Check once a week if your control unit sends any alarm.
Check if the WWTP smells like „rotten eggs“. This odour near the control unit may signal faulty functioning of your WWTP. These gases may cause corrosion of your control unit (electrical components) and the concrete tanks, too.
3. Take preventive care and maintain your WWTP regularly
Follow instructions and recommendations given by the producers regarding preventive maintenance.
Prevention and good care are two important steps to a reliable operation of your control unit and your WWTP.

4 reasons why you should use telemetry systems for your sewage treatment plant
The digital age and the concept of "smart cities" and "smart homes" have brought changes to the rigid field of wastewater treatment. Authorities and individual owners of sewage treatment plants no longer wish to wait for hours and days. They want to be informed continuously about their operation and be ready to tackle technical issues just in time. There are 4 good reasons why BONNEL telemetry systems are an invaluable tool for the WWTP monitoring now and in the future.
Monitor your sewage treatment plant 24/7
Embrace the IoT era and monitor your WWTP from your office, home or elsewhere thanks to BONNEL telemetry systems online. You can look up any details about your plant and its operation.
You can even pre-set the monitoring intervals when your WWTP will be called and asked for a status report. No need to wake up in the middle of the night, our telemetry system will automatically contact the plant and store the data for you. Sleep well while your service takes care. BONNEL telemetry systems can always guarantee a good operation.
Optimize your maintenance costs
Telemetry systems can make you some serious money. How, you may ask? BONNEL telemetry will help you schedule your service staff visits on sites and maximize their efficiency. Thanks to the SMS messages you will be informed of failure descriptions in advance. So, you can optimize business trips and save transportation and labor costs.
Monitor the whole network
Another good news is that you can include all your plants in the telemetry network at once. So, less paper work if you are a municipality with a high number of WWTPs. It will also foster trust among your fellow citizens - users if your service works flawlessly and if you keep them engaged in the community and ecology. If applicable you can even facilitate an operation model (BOOT, BOT...).
Report the data according to valid legislation
In many countries round the globe, environmentally friendly sewage treatment comes into focus. As a result, numerous legislations become stricter and they require accurate reporting from your WWTP. Go with the telemetry flow and provide precise reports on your WWTP operation to the local and national authorities.
If you wish to learn more about telemetry benefits, please contact our Sales team. We will be happy to schedule a presentation of BONNEL telemetry systems and share with you the best practices e.g. from Germany or Czech Republic.
