EnviQ®
Submerged Ultrafiltration Membranes
QUA’s EnviQ® submerged ultrafiltration membranes are engineered to enhance the performance, reliability, and efficiency of membrane bioreactor (MBR) systems. Developed by water treatment and membrane experts, EnviQ consistently delivers high-quality effluent while supporting stable operation across a wide range of municipal and industrial wastewater applications.
Each EnviQ membrane platform incorporates proprietary design features optimized for its specific membrane architecture, maximizing fouling resistance, hydraulic performance, and cleaning efficiency. The result is lower operating pressures, reduced cleaning requirements, extended membrane life, and long-term performance that helps operators lower lifecycle costs and maximize plant availability.
EnviQ® Technical Resources
High Quality Filtration
Our advanced membrane technology consistently delivers superior filtration (NTU < 1) to meet environmental regulations and extend the lifetime of downstream RO membranes.
Fouling-Resistant Design
Innovative reverse diffusion cleaning process maintains consistent productivity and stable TMP, preventing fouling buildup. It helps membranes operate at peak efficiency with stability for longer time.
Low Operating Cost
Our proprietary fouling-resistant membranes and advanced air diffuser design helps achieve consistent flux and transmembrane pressure (TMP), leading to reduced power consumption and less frequent cleaning.
Streamlined Installation & Maintenance
Our simple rack-type modular design makes installation and maintenance conveniently easy for the OEMs and operators resulting in saving valuable time and resources.
Compact Footprint
EnviQ offers higher mixed liquor suspended solids (MLSS) concentration compared to conventional processes, which reduces hydraulic retention time (HRT) and increases sludge retention time (SRT) to minimize space requirements.
How Does EnviQ® Work?
The EnviQ membrane has billions of microscopic pores on its surface that allow only water to pass, blocking impurities. Gentle suction draws the water through these pores, leaving solids behind and delivering high-quality effluent.
Peak performance is maintained with optimized fouling control, using a proprietary air process and diffuser to maintain an effective & efficient air scouring. This reduces cleaning frequency and maintains energy efficiency by preventing solids sticking to the membrane surface.
