Ultrafiltration System

The JUNDA Ultrafiltration System is specifically designed for electroplating wastewater treatment, rinse water recycling, and reverse osmosis (RO) pretreatment. Utilizing advanced PVDF ultrafiltration membranes, the system effectively removes suspended solids, colloids, metal hydroxides, emulsified oils, bacteria, and other contaminants before wastewater enters the RO system.

By reducing membrane fouling and improving feedwater quality, the UF system significantly extends RO membrane life, lowers operating costs, and increases water recovery efficiency.

Why Ultrafiltration is Essential Before RO

Reverse Osmosis membranes are highly effective for removing dissolved salts and achieving high-purity water. However, they are sensitive to contamination from suspended particles and colloidal materials commonly found in electroplating wastewater.

Without proper pretreatment, RO membranes can experience:

● Frequent fouling

● Increased cleaning cycles

● Reduced water production

● Higher operating costs

● Shortened membrane lifespan

JUNDA UF systems act as a protective barrier, removing particles as small as 0.01 microns and ensuring stable long-term operation of downstream RO systems.

How Ultrafiltration Works

Ultrafiltration is a pressure-driven membrane filtration process that removes suspended solids, colloids, bacteria, and high-molecular-weight organic compounds.

UF Membrane Specifications:

Pore Size: 0.01 – 0.1 microns

Material: PVDF / PES (hydrophilic, chemical-resistant)

Configuration: Hollow fiber (inside-out or outside-in flow)

Contaminants Removed by UF:

Suspended solids and silt

Colloidal silica and metal hydroxides

Bacteria and microorganisms

Emulsified oils

High-molecular-weight organics

TSS (Total Suspended Solids) to <1 mg/L

Contaminants NOT Removed by UF:

Dissolved salts (TDS)

Hardness (calcium, magnesium)

Low-molecular-weight organics

Small ions

This is why UF is typically used as pre-treatment for RO — UF handles the "big" contaminants, and RO handles the dissolved solids.

Frequently Asked Questions

Why is ultrafiltration necessary before RO?

UF removes suspended solids and colloids that can quickly foul RO membranes, improving overall system performance and membrane lifespan.

Can UF remove dissolved heavy metals?

UF removes metal hydroxide particles but cannot remove dissolved metal ions. RO is typically required for dissolved contaminant removal.

What is the expected membrane lifespan?

Under normal operating conditions, UF membranes typically last 3–5 years depending on water quality and maintenance practices.

Can the system be customized?

Yes. JUNDA provides customized UF systems based on wastewater composition, treatment capacity, and plant layout requirements.

Is the UF system suitable for ZLD projects?

Yes. UF is commonly used as the pretreatment stage in Zero Liquid Discharge (ZLD) systems together with RO and evaporation technologies.

Do you provide installation and commissioning services?

Yes. We provide equipment installation guidance, commissioning, operator training, and long-term technical support.
