Upgrading Rotating Biological Contactor Systems

ClearFox Retrofit of a rotating biological contactor

Rotating biological contactors, also known as rotating biological reactors, have been an established biological wastewater treatment process for decades. In Germany, this technology is particularly common at small and medium-sized wastewater treatment plants. Many of these systems have now been operating for 25 years or more. At the same time, treatment requirements continue to increase. […]

Small Municipal Wastewater Treatment Plants in Germany

ClearFox upgrade of a municipal wastewater treatment plant

Small municipal wastewater treatment plants in Germany now perform far more than the basic treatment of domestic wastewater. Fluctuating influent flows shape their day-to-day operation. Wet-weather impacts, limited space and ageing infrastructure add further complexity. Operators therefore need a fully integrated technical concept. The system must operate reliably, meet all applicable requirements and remain economically […]

Modern Measurement Technology Makes Industrial Wastewater Treatment More Efficient

Grebenhain containerized wastewater treatment plant

The food and beverage industry produces large volumes of contaminated wastewater every day. Fats, oils and organic matter significantly increase the level of contamination. At the same time, local authorities are tightening the requirements for wastewater discharge. Operators therefore need reliable technologies that combine high treatment performance with transparent process monitoring.This is precisely where PPU […]

Modular Wastewater Treatment Plants

What is a Modular Wastewater Treatment System? A modular wastewater treatment plant is a prefabricated, scalable wastewater treatment solution consisting of standardized process modules. These modules are either skid-mounted or containerized units manufactured according to the plug-and-play principle, enabling rapid on-site assembly with minimal civil works and commissioning effort. Generally, these modular treatment systems are […]

From wastewater to resource

Mixing section for pH value adjustment

From wastewater to resource – optimising recycling processes for plastic packaging Plastics recycling – especially the recycling of plastic packaging – is becoming increasingly important for a functioning circular economy. However, in addition to the actual recycling process, one aspect is increasingly coming into focus: the treatment of the wastewater produced. Washing plastics produces large […]

Further development of wastewater treatment in the oil and gas sector

Wastewater treatment system for Saudi Arabia ClearFox®

Advanced electrochemical oxidation with boron-doped diamond (BDD AEOP) The oil and gas industry is facing growing challenges in wastewater treatment. Upstream and downstream processes generate complex wastewater streams that contain large quantities of hydrocarbons, heavy metals and persistent organic substances. Processes such as biological or chemical-physical treatment are reaching their limits. Although activated carbon and […]

Wastewater treatment in extreme climate fields

Wastewater treatment in extreme climate fields ClearFox®

Efficient wastewater treatment in hot and cold regions: Temperature management in containerised wastewater treatment plants Biological wastewater treatment is a central component of modern, decentralised water infrastructure. Containerised wastewater treatment plants in particular offer flexible solutions for remote, mobile or climatically extreme locations. An often underestimated but decisive factor for the stable operation of these […]

Treating more wastewater for less money

Clearfox modernization of a pond treatment plant

Developments and challenges in municipal wastewater treatment Germany began targeted investments in wastewater treatment plants in the 1970s to respond to growing public pressure and increasing pollution. The Water Management Act (WHG) of 1976 created a binding framework for the first time, requiring industry and municipalities to treat wastewater before discharging it into the environment. […]

Modular wastewater treatment for the Food and Beverage sector

Potato washing wastewater treatment

Water, wastewater and the food and beverage sector The food and beverage industry is a major contributor to wastewater production in Europe, with significant environmental implications. In the European Union, the food and beverage sector is responsible for approximately 60% of all water consumption, highlighting the substantial water footprint associated with this sector. This industry […]
