Innovative solutions for water scarcity and water quality – 2014-2017

Innovative solutions for water scarcity and water quality – 2014-2017

Inrigo AS is one of the SME project partners in DESSIN.

Scientists, public and private water management organisations and end-users, technology providers (SMEs), support RTD experts and relevant public authorities within DESSIN testing and validation and demonstrate innovative solutions at five demo sites across Europe with a particular focus on urban areas. Inrigo’s contribution to DESSIN is to demonstrate a technology for point cleaning of overflow water from treatment plants and pipe systems for sewage handling. This is based on high-speed filtration (HRF) and adapted to the Nordic climate. Inrigo AS cooperated with Oslo municipality and was financially supported by SkatteFunn and by the 7. Framework programme for Research and Development in the EU.

Feasibility study – Future treatment plants for coastal sewage treatment – 2014

Feasibility study – Future treatment plants for coastal sewage treatment – 2014

Mapping needs and requirements linked to a future ’coastal sewage treatment technology’.

The technology is effective, cost optimal and adapted to the needs Norwegian municipalities and others will have for handling their emissions in the future. Inrigo AS cooperated with SINTEF and Leksvik municipality. The project received support from the VRI programme at the Research Council.

Micro-/Ultrafiltration for small water treatment plants – 2012-2014

Micro-/Ultrafiltration for small water treatment plants – 2012-2014

Developed compact water treatment technology for water plants with small production volumes.

The technology does not have any harmful effluents to the environment and is based on micro and ultra filtration. Inrigo cooperated with Rissa municipality and received support from SkatteFunn.

Purification of recycled water – 2012-2014

Purification of recycled water – 2012-2014

Developed, built and tested a prototype with advanced purification technology that combines the use of membranes, biology and oxidation (multistage MBR-AOP technology).

Tests that were done in cooperation with Trondheim municipality showed that 75-99% of micro-organic pollutants and trace-impurities in recycled wastewater were cleansed.  The technology provided a higher cleaning effect, required less space and used less energy than similar technologies. Inrigo AS collaborated with Normex AS, with support from SkatteFunn and the environmental technology scheme at Innovation Norway.

High quality reuse of grey water – 2012-2013

High quality reuse of grey water – 2012-2013

In collaboration with NTNU Inrigo AS implemented a Research and Development project whose main aim was to prepare a recommendation for the development of technology for cleansing of grey water for high quality reuse in so-called Smart Water systems.

The project received qualifying support from Regionalt Forskningsfond Midt-Norge (Norwegian regional research fund).

Feasibility study – specifications for wastewater treatment in semi-centralised systems – 2012

Feasibility study – specifications for wastewater treatment in semi-centralised systems – 2012

Prepared specifications for technology that satisfy the requirements and needs for wastewater treatment in semi centralised supply and treatment systems for water.

The specifications formed the basis for further technology development in a bigger follow-up project. The technical feasibility studies were carried out in collaboration with Inrigo AS and NTNU’s Institute for Water and Environment, supported by the VRI programme from the (Norwegian) Research Council.

Treatment plants with ceramic micro filter membranes – 2009-2011

Treatment plants with ceramic micro filter membranes – 2009-2011

Developed and built a protoype treatment plant for drinking water based on ceramic micro filter membranes.

Ceramic membranes are particularly suitable for raw water containing humus, have a longer lifespan and require less use of chemicals than traditional membranes. Micro filtration has far higher capacity than ultra filtration and nano filtration. Inrigo AS collaborated with Leksvik municipality, having gained OFU support (”Olje for utvikling” - oil development grant) from Innovation Norway.
