Provides integrated fixed-film activated sludge systems with two products: BioWeb and BioPortz. BioWeb is a rope-type fixed-film media system for use in activated sludge and lagoon upgrades to increase capacity. BioPortz is a dynamic media for use in activated sludge systems. This system includes millions of independently moving BioPortz carriers continually circulating through the aeration basin in a random motion ensuring substrate transfer to the biomass. The increased biomass provides additional capacity in a given tank size over conventional activated sludge. Visit their website at www.entexinc.com
