Municipal waste water treatment

The daughter company of Norwegian Technology (NT) – Norwegian Process Services (NPS) provides the municipal waste water industry with technical solutions and product. The company was started as a results of a consultancy job in collaboration with IVAR. Norwegian Technology developed a portfolio of chemicals that will change the municipality standard for good.

Grødaland municipality plant built and drifted by IVAR is currently utilizing the N-SEP 438. The plant treats around 150 000 pe highly concentrated waste water with high fat content. IVAR has utilizing N-SEP 438 over a year with excellent and biogas suspended solids separation degree, biological treatment and biogas production.

The N-SEP 438 has proved to work very efficiently at several locations in Norway. A suspended solids separation degree of up to 85 percent is achieved along with several other advantages.

Dissolved Phosphor will not precipitate during treatment. As a result, significantly less Phosphor is needed for biological treatment.

The chemicals generate large fnocs which can easily be separated with several existing mechanical treatment equipment.
