Product Description
30-50 TPH Capacity | SDI 5-8 Inlet Tolerance | Specialized for Challenging Water Sources
Product Overview
The FG-UF-HSDI is a specialized skid-mounted ultrafiltration system engineered to handle high SDI (Silt Density Index) water sources ranging from 5 to 8. Unlike standard UF systems that struggle with high particulate loads, this system incorporates enhanced pretreatment and robust membrane design to maintain consistent performance in challenging conditions.
With a flexible capacity range of 30-50 TPH (7,920-13,200 GPD), the FG-UF-HSDI is ideal for regions with turbid surface water, industrial effluents, and agricultural runoff where conventional pretreatment methods are insufficient or cost-prohibitive.
Technical Insight: Understanding SDI Challenges
SDI values above 5 indicate high fouling potential that can rapidly clog standard membrane systems. The FG-UF-HSDI incorporates:
- Enhanced hydraulic design for better particle distribution
- Anti-fouling PVDF membranes with reinforced fiber structure
- Intelligent backwash sequencing that adapts to feed water quality
- Optional in-line coagulant dosing for extreme conditions
Technical Specifications
SDI Tolerance Range Comparison
The FG-UF-HSDI is specifically engineered to handle the challenging SDI range where standard systems fail:
Note: For water sources with SDI >8, we recommend adding our optional coagulation-flocculation pretreatment module.

Specialized Features for High SDI Applications
The FG-UF-HSDI incorporates several design innovations specifically for challenging water conditions:
Adaptive Backwash Control
Intelligent PLC monitors trans-membrane pressure (TMP) and adjusts backwash frequency and duration based on actual fouling rate, not just time intervals.
Reinforced Membrane Design
PVDF fibers with 30% thicker walls and anti-fouling surface modification resist compaction and maintain flux under high particulate loading.
Enhanced Hydraulic Design
Wider feed channels and optimized flow distribution prevent particle accumulation and channel clogging common in high SDI applications.
Optional Coagulant Dosing
Integrated chemical dosing system with pH adjustment capability for inline coagulation when dealing with colloidal particles.
Application Scenarios
The FG-UF-HSDI is specifically designed for applications where conventional pretreatment is insufficient or impractical:
Southeast Asia Surface Water
River and lake water in tropical regions often has SDI 5-8 due to soil erosion, algal blooms, and seasonal variations. This system provides reliable pretreatment for municipal and industrial water supplies.
Typical Locations: Vietnam's Mekong Delta, Indonesia's rivers, Thailand's agricultural regions
Challenge: Seasonal variations with monsoon rains increasing turbidity and SDI dramatically
Industrial Wastewater Reuse
Many industrial processes generate effluent with high suspended solids that standard UF cannot handle. This system enables water recycling in challenging industrial environments.
Typical Industries: Textile dyeing, paper/pulp manufacturing, mining operations, metal finishing
Challenge: Variable wastewater composition with high and fluctuating particulate loads
Agricultural Runoff & Processing
Agricultural operations often generate water with high organic and inorganic particulates. This system can treat this water for reuse in irrigation or processing.
Typical Applications: Palm oil mill effluent, rice processing wastewater, livestock runoff, fruit/vegetable washing
Challenge: High organic content combined with soil particles creates difficult-to-treat matrices
