Microfiltration for Solids Management
High-Performance Solids Separation — Oil & Gas and Mining Wastewater
Microfiltration — 0.1–0.2 µm Hollow Fiber Membrane
The Microfiltration (MF) System is a modular, pressure-driven membrane solution engineered to remove suspended solids, emulsified oils, colloids, and biological matter from complex industrial wastewater. Designed for upstream and midstream oil & gas and mining operations, it delivers consistent filtrate quality, high uptime, and low lifecycle cost — even in harsh, variable feedwater conditions.
PVDF or PES hollow fiber/flat sheet membranes in crossflow or dead-end configurations deliver reliable clarification and pretreatment for the full downstream treatment train.
Key Benefits
- Removes TSS, turbidity, colloids & emulsified hydrocarbons to sub-NTU filtrate levels
- Produces effluent suitable for RO, IX, evaporation, or direct process reuse
- Stable performance across variable feedwater composition and loading
- Significantly reduced coagulant/flocculant vs. DAF and clarifiers
- Lower sludge volumes — reduced disposal frequency and hauling costs
- Fully automated; minimal operator intervention required
- Modular, scalable skid packages — pilot through permanent installations

Integration with Downstream Treatment
| Tech | Process | How MF Helps |
|---|---|---|
| RO | Reverse Osmosis | Protects RO membranes from colloidal fouling; extends membrane life and reduces cleaning frequency |
| NF | Nanofiltration | Stabilizes feedwater quality ahead of NF trains; reduces scaling potential and improves flux stability |
| MVC/MVR | Thermal Concentration | Reduces suspended solids and oil loading to evaporators; minimizes scaling, carryover, and tube fouling |
| IX | Ion Exchange / Softening | Extends resin bed life; improves regeneration efficiency and capacity |
| ZLD | Zero Liquid Discharge | Enhances overall system recovery; reduces brine volume and concentrate disposal requirements |
