First Report

Pharem Filtration System by Pharem Biotech

Pharem Biotech, headquartered in Södertälje, Sweden, is applying biotechnology to water treatment for the removal of organic micropollutants. It has developed an enzymatic filtration process whereby enzymes used in a chemical-biological process break down biodegradable contaminants in a wastewater stream. The enzymes are tailored specifically to more difficult-to-break-down biodegradable pollutants and remove them to parts per billion (ppb) levels. The process claims to be energy independent and little to no external energy is required.


Xzero-MD by Xzero / Scarab

Xzero has developed a membrane distillation (MD) system initially aimed at the semiconductor industry for both producing ultrapure water as well as treating wastewaters (particularly spent rinse water) from the fabrication plants (fabs). The company is marketing the MD technology as an alternative to established technologies such as reverse osmosis and electrodeionisation. In an MD system, vaporised water overcomes surface tension and passes through a membrane before being condensed on the other side, while particles are left behind due to their inability to escape the surface tension. The company uses an air gap configuration, where there is an air gap between the membrane and a cooled wall within the system.
