A producer of cut flowers in Germany operates fields, greenhouses, and an online shop to grow and sell peonies. For this, the company needs a lot of water to irrigate the plants. The customer intended to generate some of this through wastewater treatment. The company itself produces about 15 m³ of wastewater per day. For this, the customer asked for a wastewater treatment plant.
The first challenge with this project was the space required on the company premises. The client wanted an underground installation, as there was already a simple sewer system on site. The ClearFox® team was to connect the new treatment plant to this. Therefore, the treatment solution had to be particularly reliable.
The second challenge was the strict regulations regarding use for irrigation. When taking wastewater samples, the in-house laboratory of PPU found a BOD5 of 400 mg/l on average and a COD of 700 mg/l on average. This means that the wastewater is predominantly organically polluted, which is why biological wastewater treatment was the obvious choice.
For this project, the ClearFox® team offered the customer a wastewater treatment plant with FBBR technology in below-ground concrete tanks. The engineers planned with their own concrete tanks, which they equipped with the fixed bed material and the aeration system in the main factory in Bayreuth. They delivered these ready-assembled to the customer, where they only had to be installed, connected to the sewer system, and put into operation.
The wastewater first flows into a buffer tank. Since this occurs very irregularly – the employees hardly produce any wastewater overnight or at weekends – the buffer tank enables the treatment plant to cope very well with the fluctuating wastewater loads. At regular intervals, the system pumps the wastewater into the fixed-bed reactor. This is where the biological treatment takes place. A third tank serves as storage for the sludge that accumulates. However, the system works so efficiently that the client only needs to empty the sludge storage tank very rarely.
For this project, the ClearFox® team took over the complete planning of the project, the provision of the concrete tanks, the manufacturing in the main factory, the transport to the customer, the below-ground installation, the commissioning, and the training of the employees. The fixed-bed treatment plant from PPU meets the customer’s requirements, which is why they can use their wastewater for irrigation.
Yes, the ClearFox® fixed bed treatment plant can be adapted to many projects. The solution is particularly suitable for organically contaminated wastewater and flexible volumes. Our engineers will examine your individual requirements and develop a tailor-made solution for your needs.
Underground installation is often possible and ideal for saving space. The tanks and the system are designed to take up little space. Our experts will check on site whether the conditions on your site allow underground installation.
Yes, the system is optimized for fluctuating wastewater volumes. The buffer tank compensates for the fluctuations so that the biological treatment can take place evenly and efficiently.
Maintenance is minimal. Sludge rarely needs to be removed and regular checks ensure that the system works reliably. Our team offers training for your employees and an optional maintenance service.
The duration depends on the specific requirements of your project. Typically, planning and manufacturing takes a few weeks, and installation can be completed within a few days.
