Description

30-50 TPH Capacity | SDI 5-8 Inlet Tolerance | Specialized for Challenging Water Sources

Model: FG-UF-HSDI

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

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

Why Choose FG-UF-HSDI?
