Sewage treatment is facing challenges such as climate change, low resource efficiency and poor environmental and human protection. More than 30 million people are not connected to wastewater treatment plants (WWTP) in the EU yet. EU water body quality is still low ecologically and chemically not fulfilling current water directives. Moreover, new water pollutants are arisen (pharmaceuticals, drugs, microplastics, etc.).
For this reasons, collecting and treating wastewater has required huge investment across Europe in recent decades. However, EU water body quality status is still low ecologically and chemically. New innovative technologies must be brought to the market to overcome these challenges, increase water quality in rivers, lakes and seas and give raise to the advanced 21st century WWTP.
Sewers collect sewage and transport it to a wastewater treatment plants. There, differing levels of treatment can be applied and usually include:
As Figure 3 shows, SewaTOR can be used at different locations within the WWTP:
SewaTOR breaks through technology defragments the sewage sludge out of the different WWTP stages to create a more homogeneous material, with less viscosity, much easier and fast to process and transport. This cuts down WWTP energy consumption, lowering electricity related CO2 emissions and increases the biogas production yield leading to a more resource efficient WWTP.
The processing time is greatly reduced enabling the downsizing of the WWTP and lowering CAPEX requirements. Moreover, the amount of disposed sludge decreases (up to 100%) alongside its harmful pathogen and chemical load. With its sterilization effect, also accompanied by integrated sanitization with UV-C and/or O2, SewaTOR also eliminates germs and all organic material in the discharged water accomplishing the new EU sanitation requirements, enabling water recycling, and solving the climate change scarcity problems.
herefore, SewaTOR is an innovative wastewater treatment technology that strongly contributes to accomplish the water quality required by the EU WFD in water bodies and to overcome the new challenges devised by the EEA for the European WWTP industry in the 21st century.
