QUA – Pure Technology

EnviQ®

Submerged Ultrafiltration Membranes

QUA’s EnviQ® submerged ultrafiltration membranes are designed by our water experts to improve the performance and reliability of MBR facilities. EnviQ’s unique design provides high-quality product water quality and is optimized for robust operation, enabling reverse diffusion and purpose-designed air diffusion to optimize scrubbing efficiency, reduce operating pressure and minimize cleaning frequency.

The EnviQ membrane technology is engineered for superior performance, high quality filtration, small footprint and low OPEX. It is available in two variants – a flat sheet membrane and PVDF hollow fibre membrane to provide consistent ultrafiltration-quality effluent.

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 diffuser to maintain consistent & continuous air scouring. This reduces cleaning frequency, maintains energy efficiency by preventing solids sticking to the membrane surface, and eliminates the potential for septic conditions due to solids settling at the tank bottom.

Applications of EnviQ®

Municipal wastewater treatment

Wastewater treatment for industries like pharma, food & beverage, and manufacturing

Surface water filtration (non-biological mode)

Institutional sewage water treatment for IT parks, hospitals, and hotels

EnviQ® – Product Variants

This high strength submerged ultrafiltration membrane comes in two variants – EnviQ XL and EnviQ RF.

EnviQ XL -Submerged Ultrafiltration Membranes

EnviQ XL, QUA’s latest innovation brings the proven technology of EnviQ Flat Sheet to cater higher flow capacities while providing a much smaller footprint. This robust offering has been designed to reduce the installation footprint by offering higher membrane area, with the proven reliability QUA is known for.

Less Space, More Water

Higher flow in smaller footprint to boost capacity in less space. Ideal for applications where large flow water is required and space is a big constraint.

Optimized Energy Consumption

Low air flow requirement and high productivity allow for optimized energy consumption resulting in lowering the operating cost.

Unmatched Durability

Our well-anchored, self-supporting PVDF flat sheet UF membrane ensures superior performance and longevity, even in challenging wastewater environment.

Reverse Diffusion

Innovative reverse diffusion with clean water maintains consistent productivity and stable TMP, preventing fouling buildup.

EnviQ RF is next-gen submerged ultrafiltration membranes that redefines wastewater treatment with its innovative reinforced PVDF hollow fiber membrane and unique airflow distribution system, ensuring high-quality effluent despite high turbidity.

High Durability Membranes

This reinforced, robust hollow fiber membrane has high tensile and mechanical strength that effortlessly handles very high MLSS feed water. It offers excellent durability and performance in challenging applications.

High Quality Product Water

Provides ultrafiltration quality water with >99% TSS reduction.

Extended Membrane Life

These are back washable membranes which ensure efficient cleaning and consistent transmembrane pressure. It not only improves filter efficiency but extends membrane life while minimizing downtime significantly.

Unique Dual Airflow Distribution System

Optimizes power consumption and reduces cleaning requirement.
