‘Relying on soil and purified wastewater’
Circularity and a sustainable living environment are clear-cut priorities the NTP Group. In addition to taking measures that save energy and resources within our organisation and projects, the NTP group is constantly searching for new methods and technologies that can help us bring sustainability into practice.
Perozone soil remediation is one of these methods. The perozone method allows for the proper remediation of many different types of soil contamination with natural ingredients such as ozone and hydrogen peroxide. These ingredients either break down a large number of substances in the soil immediately, or release a significant number of contaminated substances, which can then by pumped up.
The perozone method is a low-carbon process, because it does not require the transport of excavated and subsequently purified soil or the supply of new, clean soil. In addition, the method can be monitored and controlled digitally and remotely and leads to no potential environmental hazards after completion. The continued development of the perozone method has already led to an oxidising power of approximately 3.0 V. This allows us to break down substances that used to require extremely high temperatures of > 1000 °C in the past.
Removing drug residue from wastewater
The perozone method can also be used to remove drug residue from wastewater. According to the National Institute for Public Health and the Environment (RIVM) at least 140,000 kilos of drug residue ends up in our surface water every year. That is more than 8 times the amount of crop protection products that end up in the water each year (17,000 kilos).
At present, drinking water treatment processes manage to remove the vast majority of contaminants found in surface water. After purification, drug residue concentrations in our drinking water are too low to have a real effect on the human body, but due to the aging population and increasing medicalisation of society, drug use is only set to grow. Besides, climate change will increase the likelihood of periods prolonged drought and low-water levels, which can lead to significant increases in drug residue concentration levels.
The first pilots with perozone methods in the US and Germany seem to indicate that this method might be a real breakthrough. Because this method uses natural ingredients to remove drug residue, it is an environmentally-friendly way of obtaining clean, drug-free drinking water.
All in all, perozone soil remediation is environmentally friendly, effective and cost-effective, in addition to making a significant contribution to soil and water quality.
