Descripción de producto

I.Overview
Ultrafiltration (UF) system is mainly used as the pretreatment unit of Reverse Osmosis (RO) in seawater desalination, which is used to efficiently remove suspended solids, colloids, algae and microorganisms from seawater, significantly reduce the risk of contamination of RO membrane, and improve the stability and efficiency of the overall system. As the “guardian” of RO, the system's stability and economy are greatly improved through efficient pretreatment.
 Its core value lies in: safeguarding RO membrane safety (reduce the risk of contamination, extend the life), energy saving and environmental protection (reduce chemicals, compatible with energy recovery), and adapting to complex water quality (high algae, high turbidity seawater can be treated).


II.Typical Process Flow 
Conventional Desalination Pretreatment Process :
Seawater → Sieve Filtration (1~5 mm) → Coagulation (optional) → Ultrafiltration → Reverse Osmosis → Post-treatment (Mineralization/pH Adjustment)


Submerged ultrafiltration (S-UF) process :
seawater → self-cleaning filter → submerged ultrafiltration → security filter → RO


Integrated energy recovery system :
seawater → UF → high-pressure pump → RO → energy recovery unit (e.g. PX) → produced water


III.Core Attribute Parameters

Performance Requirements for Ultrafiltration Membranes
Parameter Typical Value Description
Membrane Material PVDF, PES, Ceramic Resistant to seawater corrosion (PVDF is optimal), anti-biological fouling.
Pore Size 0.02–0.05 μm Balances flux and rejection rate (bacteria removal rate >99.9%).
Flux (LMH) 40–80 (20–30℃ seawater) At low temperature (<15℃), flux decreases by 20%–30%.
Operating Pressure 0.3–1.5 bar Submerged ultrafiltration operates at lower pressure (0.1–0.5 bar).
Recovery Rate 85–90% Concentrated water discharge: ~10–15%.
Outlet Water Quality
Index Ultrafiltration Effluent RO Inlet Requirement
Turbidity (NTU) <0.2 <1
SDI15 <3 <5
Total Bacteria Count <10 CFU/mL –
TOC (mg/L) <1 –


IV.Applicable Scenarios 
Large Desalination Plant 
Marine/Island Small Desalination System 
Hybrid Process (UF+RO+Energy Recovery)


V.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
