HiSep™ | High-Performance Ultrafiltration Technology
Precision Separation. Consistent Quality. Reliable Protection.
HiSep™ is InfraCorp’s proprietary ultrafiltration (UF) membranetechnology, engineered to deliver exceptional removal of suspended solids, bacteria,viruses, and colloidal matter from water. Utilizing advanced hollow-fibermembranes with pore sizes between 0.02 and 0.05 microns, HiSep™ creates a robust physical barrier to impurities, ensuring stable and consistent permeate quality even under challenging and variable feedwater conditions.
Designed as a critical pretreatment solution, HiSep™ protects and enhances the performance of downstream processes such as reverse osmosis (RO) and advanced oxidation processes (AOP). Its robust design ensures long-term operational stability and helps clients achieve compliance with the world’s most stringent water quality standards across industrial, municipal, and reuse applications

Performance Highlights:
BioMem™ process integrates a biological reactor, where organic matter is biologically degraded, with membrane filtrationmodulesthat act as a physical barrier to solids and pathogens. This eliminates the need for secondary clarifiers or tertiary filtration, producing highly purified effluent in a single step.
Typical Performance:
- BOD < 5 mg/L
- TSS < 1 mg/L
- Turbidity < 0.1 NTU
- Complete removal of suspended solids and pathogens
Key Applications:
- Desalination Pretreatment
- Reverse Osmosis (RO) Pretreatment
- Wastewater Reclamation & Reuse
- Potable Water Production
- Industrial Process Water Treatment
Why HiSep™?
When reliability, water quality, and system protection matter most, HiSep™ stands apart.
-
- Superior Filtration Efficiency :HiSep™ removes >99.99% of suspended solids, bacteria, and viruses through ultrafine hollow-fiber membranes (0.02–0.05 microns), ensuring SDI < 3 and turbidity < 0.1 NTU—ideal for downstream RO and reuse.
- Engineered for Challenging Waters :Whether treating industrial effluent, seawater, or secondary-treated municipal wastewater, HiSep™ delivers stable performance even under fluctuating feedwater conditions.
- Low Lifecycle Cost :With high membrane durability, low fouling rates, reduced chemical consumption, and optimized CIP protocols, HiSep™ minimizes OPEX and extends system lifespan.
- Modular &Scalable :From compact containerized units to large-scale skids, HiSep™ systems are plug-and-play, easily integrated into existing treatment trains or new builds.
- Backbone of Advanced Treatment :HiSep™ is the foundation of high-reliability processes such as:
- Reverse Osmosis (RO)
- Advanced Oxidation (AOP)
- Zero Liquid Discharge (ZLD)
- Water Reuse & Recycling
-
- Proven Across Sectors
Deployed in industrial, municipal, and desalination applications, HiSep™ helps clients meet the most stringent water reuse and discharge regulations (e.g., CPCB, EPA, WHO, EU).
Industrial Reuse | HiSep™ Value Proposition
HiSep™ provides industrial facilities with a robust and reliable pretreatment barrier that ensures consistent protection of downstream RO and ZLD systems—critical for water reuse and sustainability initiatives.
With proven resistance to high solids, variable effluents, and aggressive cleaning cycles, HiSep™ enables:
- Reduced downtime and RO fouling
- Lower total cost of ownership (TCO) through long membrane life and minimal chemical dependency
- Compliance with stringent internal and environmental reuse standards (e.g., cooling tower makeup, boiler feed, process reuse)
- Flexible design suited for retrofits and greenfield projects in sectors like textiles, petrochemicals, F&B, and pharmaceuticals
Desalination Pretreatment | HiSep™ Value Proposition
HiSep™ is engineered as a high-performance pretreatment barrier for seawater and brackish water reverse osmosis (SWRO/BRRO) systems. Its precision filtration protects RO membranes from fouling caused by suspended solids, biofouling agents, and colloids.
HiSep™ enables desalination operators to:
- Achieve stable RO performance and reduced cleaning frequency
- Maintain SDI < 3 and turbidity < 0.1 NTU for optimal membrane protection
- Withstand harsh coastal water conditions with durable PVDF fibers
- Maximize plant uptime and improve water recovery
Ideal for municipal desalination plants, island resorts, industrial coastal users, and offshore facilities.
Municipal Wastewater & Reuse | HiSep™ Value Proposition
In municipal wastewater reuse and tertiary treatment applications, HiSep™ ensures safe, high-quality effluent that meets or exceeds international reuse standards (e.g., WHO, USEPA, ISO 16075).
Key benefits include:
- >99.99% removal of pathogens (bacteria, viruses, protozoa)
- Consistently low turbidity and SDI for public safety and regulatory compliance
- Scalable systems for STPs, ETPs, and reuse schemes (e.g., irrigation, aquifer recharge, non-potable use)
- Lower operational costs compared to conventional sand or media filtration
HiSep™ is ideal for utilities aiming to close the water loop and support circular water economy strategies.
