Membrane ultra-filtration unit AQUALITY® UF

for wastewater treatmentprocess water

Our AQUALITY®membrane Ultra-filtration and Reverse Osmosis solutions are designed for closing the water loop. Although both use membranes as a barrier, the process of reverse osmosis is not the same as filtration. Filtration is the removal of particles by size exclusion, while in reverse osmosis such physical holes may not exist. With reverse osmosis, water is able to diffuse through the membrane polymer by bonding between segments of the polymer's chemical structure. Our AQUALITY® membrane technology produces high-quality water and integrates seamlessly in any existing wastewater treatment or water recovery plant. • AQUALITY® UF Ultrafiltration • AQUALITY® RO Reverse Osmosis • AQUALITY® HRRO High Recovery Reverse Osmosis AQUALITY® UF. Setting a barrier to bacteria Our AQUALITY® Ultrafiltration (UF) is a variety of membrane filtration in which hydro-static pressure forces a liquid against a semi-permeable membrane. The permeable membrane becomes a barrier to suspended solids and bacteria, producing water with very high purity and low silt density. Ready for drinkwater and Reverse Osmosis applications The filtrate is typically characterized by a complete removal of suspended solids, a log 5 reduction (>99.999%) of bacteria such as Cryptosporidium, a filtrate turbidity <0.1 NTU (no matter what the feed-water turbidity is) and an SDI (Silt Density Index) < 2. This means that the filtrate is ready for reuse in drinking water applications or is perfectly pre-conditioned to serve as feedwater for a reverse osmosis installation.
