FEED WATER & PRETREATMENT
Raw water enters the system. Depending on its quality, pretreatment may be needed to protect the membranes.

Advanced water filtration for cleaner, more reliable water.
Shivsu Watec ultrafiltration (UF) systems use membrane technology to retain fine suspended solids, colloidal particles and many microorganisms. Systems can be configured for RO pretreatment, process water or suitable commercial applications.

01 / UNDERSTANDING UF SYSTEMS
What Is an Ultrafiltration System?
A membrane-based filtration system that separates fine suspended solids, colloidal particles and many microorganisms from water.
MEMBRANE FILTRATIONPHYSICAL BARRIER
Separate particles from waterMembrane pores allow water through while retaining larger particles.
Water can appear clear while still containing fine suspended matter, colloidal particles and microorganisms. Ultrafiltration uses specialised membranes as a physical barrier to retain many of these contaminants.
Unlike media-bed filtration, UF separates contaminants at a membrane surface. It does not remove most dissolved salts, so additional treatment such as reverse osmosis may be needed when low-mineral water is required.
Retain fine suspended particles
Membranes hold back suspended solids and colloidal particles from the water stream.
Reduce many microorganisms
UF can retain many bacteria and other microorganisms, depending on membrane specifications and operation.
Prepare water for the next stage
Use UF as standalone filtration or as pretreatment before reverse osmosis, where suitable.
02 / THE FILTRATION PROCESS
How Does Ultrafiltration Work?
UF membranes provide a physical barrier to fine particles. System design and cleaning routines depend on feed-water quality, membrane type and required flow.
02
MEMBRANE FILTRATION
Water passes through UF membranes while fine suspended solids, colloids and many microorganisms are retained.
03
PERMEATE COLLECTION
Filtered water, known as permeate, is collected for use or directed to the next treatment stage.
04
BACKWASHING & CLEANING
Backwashing and periodic membrane cleaning help remove accumulated deposits and maintain filtration performance.
i
Important note — UF removes many particles and microorganisms but does not remove most dissolved salts or guarantee drinking-water safety by itself. Additional treatment or disinfection may be required for the intended use.
03 / WHERE IT IS USED
Ultrafiltration Applications
UF is used where fine-particle removal and consistent filtration matter. The right application depends on source-water quality, membrane specifications and the treated-water standards required.
01
RO plant pretreatment
Reduce suspended solids and colloidal particles entering downstream RO membranes.
02
Wastewater reuse
Support reuse schemes when UF is suitable for the source water and reuse target.
03
Industrial process water
Provide a filtration stage for manufacturing and industrial water systems.
04
Food and beverage
Help manage fine particles in process-water applications with suitable system design.
05
Pharmaceutical industries
Use as one stage in a treatment train designed for the required water quality.
06
Commercial buildings
Configure filtration for appropriate institutional and commercial water uses.
07
Pretreatment systems
Add membrane filtration where conventional filtration alone is insufficient.
08
Water quality improvement
Help provide more consistent filtered water when matched to the incoming water.
04 / SYSTEM SELECTION
Designed Around Your Water Quality
Ultrafiltration system selection depends on the water entering the plant, the required flow rate, membrane specifications and the quality needed at the outlet.
Water analysis Membrane selection Cleaning schedule
01
Incoming water analysis
Review suspended solids, turbidity and other feed-water characteristics that affect pretreatment and membrane operation.
02
Required flow rate
Account for normal demand, peak flow and operating hours when sizing the system.
03
Membrane type and specifications
Select a membrane configuration based on the application and required filtration performance.
04
Treated-water quality target
Define whether permeate is used directly or sent to another treatment stage, such as RO.
05
Cleaning and maintenance
Plan backwashing, periodic cleaning and performance checks to help maintain filtration efficiency.

MEMBRANEFILTRATIONUF SYSTEM GUIDE
UF systems remove suspended solids, fine particles and many bacteria and other microorganisms. Performance depends on the membrane used and how the system is operated.
UF removes suspended particles and larger contaminants through membrane filtration. Reverse osmosis also removes most dissolved salts and many other substances that UF cannot remove.
Yes. UF is commonly used as RO pretreatment to reduce suspended solids and colloidal particles reaching the RO membranes, which can help manage membrane fouling.
Not always. UF can remove many particles and microorganisms, but it may not remove dissolved chemicals, salts or all harmful microorganisms. Depending on source-water quality, additional treatment or disinfection may be needed.
Yes. Maintenance usually includes backwashing, periodic membrane cleaning and performance checks to help maintain filtration efficiency and membrane life.
