Converting Waste to Value
Inrigo designs and delivers advanced solutions that meet the strictest regulations in the EU and Norway. We tailor the solution based on the specific characteristics of the wastewater and the requirements for treatment.
We use advanced filtration systems that effectively remove organic pollutants, nitrogen, phosphorus, and micropollutants. With our solutions, wastewater can be recovered and reused in Class B, Class A/A+ (non-potable or potable) standards. Our compact designs make the solutions ideal for urban and industrial environments where space is a limited resource.
