Hydration Technology Innovations (HTI) has reported that the company has manufactured a new thin film composite membrane, its latest addition to the OsMem Forward Osmosis (FO) membrane line.
The company has started the commercial production of this highly durable thin-film membrane and produces spiral elements, which have a flux rate and permeability twice that of the Cellulose Tri-Acetate (CTA) FO membrane.
Walt Schultz, HTI’s Chief Executive Officer stated that efficient filtration has been offered by the OsMem FO membrane line in order to treat industrial waste streams, and the efficiency level has been greatly increased. Plant designers and OEMs can possibly decrease the investment and footprint in FO systems, with the launching of high performance FO composite membrane line, according to Walt.
This thin film composite membrane has highly permeable, high rejection membrane, whose pH tolerance varies from 2.0 to 12.0. Also, it can survive severe pressure retarded osmosis (PRO) operating circumstances. The production membrane flat sheet flux averages 49 LMH in PRO and 20 LMH in FO mode. The new product’s salt rejection values favorably compare for polyamide membranes at a minimum of 99.3%.
The thin film composite membrane from HTI offers a cost-effective option to treat industrial wastewater, with the help of RO pre-treatment that leads several innovative system patterns. The new membrane can be potentially used in industrial applications like Osmotic Membrane Bioreactors (OsMBR), cooling tower make-up water, oil & gas wastewater and landfill leachate.
