Sewage treatment systems for sustainable municipal water treatment

Domestic or municipal sewage treatment is crucial for safeguarding public health and protecting the environment. As wastewater from homes contains a complex mix of organic matter, nutrients, pathogens, and pollutants, effective treatment is essential to prevent waterborne diseases and pollution of natural water bodies.

For this reason, municipal sewage treatment utilizes a big range of sewage treatment systems. From traditional methods like activated sludge processes – in which microorganisms break down organic matter, to advanced techniques, such as membrane bioreactors – that employ membranes to filter out contaminants. Each method offers unique advantages depending on factors like space availability, treatment efficiency, and environmental impact.

Many civil servants responsible for sewage treatment systems are confronted with tighter discharge rules, higher energy bills, stricter CO2 emission guidelines, a need for increased capacity and decentralized treatment. Domestic sewage plants also urgently need to reduce activated sludge disposal to enhance operational efficiency and environmental sustainability and decrease costs.

In order to solve these challenges, municipalities are looking for specialized solutions. They seek cost-effective and sustainable retrofit solutions for municipal water treatment and public water filtration that can be retrofitted or can extend existing sewage treatment systems. Paques offers them exactly this kind of biological wastewater treatment systems.

Focusing on sustainability, low OPEX and resource recovery, Paques has developed a wide variety of sewage treatment systems.

Our unique UBOX^® sewage treatment system was created for municipal water treatment in tropical regions. By combining anaerobic treatment, aerobic treatment, secondary clarification and biogas scrubbing into one single tank, the UBOX^® guarantees great efficiency in BOD removal, the lowest OPEX (since sludge production and energy consumption are reduced) and the smallest footprint.

Paques also offers the CBD^® technology, which enables highly efficient activated sludge digestion, thus reducing the volume and cost of sludge disposal.

Furthermore, the ANAMMOX^® and PHOSPAQ^® technologies can be used for sidestream ammonia and phosphorus removal from the digestate of activated sludge digesters.

Finally, Paques offers the THIOPAQ^® technology to remove the H₂S from the biogas generated by existing UASB reactors at domestic sewage treatment plants and by activated sludge digesters, enabling municipalities and concessions to safely use the biogas as energy source.
