Renasys has developed a state-of-the-art fine particle filtration solution for wastewater removing 99% of particles above 5 microns, regardless of industry, scale, or wastewater composition. The purification capacity [measured in filtration level, cubic meters of water purified and per time unit] represents a quantum leap in relation to the current technologies on the market. Their proprietary solution is modular, compact, closed loop, operationally autonomous, energy efficient, and scalable with the potential to transform current infrastructure for water purification and current purification methods. The solution paves the way toward next-generation carbon harvesting accelerating Wastewater Treatment Plants towards Net-Zero energy consumers with climate-friendly operations, or even net renewable energy producers. In EUROPE alone, carbon energy potential from wastewater equates to 87,500 GWh per year - equivalent to the annual energy consumption of almost 14% of Europe's population.

The environmental benefits

  • Test data from our industrial pilot operating with a 40micron filter belt has demonstrated reduction of Suspended Solids (SS) from municipal sewage of 60%
  • Test data from our industrial pilot operating with a 40micron filter belt has demonstrated Chemical Oxygen Demand (COD) reduction of 42% and Biological Oxygen Demand (BOD) reduction of 36%
  • With a Renasys filtration solution reducing SS by 60% (BOD by 30%) we have estimated that a downstream biological treatment stage can be 30-49% smaller volume
  • Greater than 2X net energy recoverable from sludge for conversion to heat and biofuels
  • ZERO chemical + flocculant use results in a sludge that can be utilized as an alternative to synthetic fertiliser and soil conditioner
  • Solution is a provider of a nutrient rich sludge at a cost, quantity, and quality that was previously unimaginable, thereby catalysing a supply-chain for natural fertilisers that closes the loop of currently wasted bio-resources

The Financial benefits

  • Savings of +258MNOK to a customer over a 20yr time frame for the operation of a 45,000PE wastewater resource recovery facility
  • ZERO upfront capital investment
