Microfiltration (MF) Systems

Microfiltration systems employ membrane technology with pore sizes ranging from 0.1 to 10 microns to remove suspended solids, bacteria, and large particles from water through physical straining. The technology operates at low transmembrane pressures (5-30 psi), making it energy-efficient for large-volume applications. Cross-flow filtration configuration prevents particle accumulation on membrane surfaces while maintaining consistent permeate quality. Advanced hollow-fiber and spiral-wound membrane configurations maximise filtration surface area per unit volume while providing mechanical strength for long-term operation. Automated backwashing systems using filtered water or compressed air remove accumulated particles, maintaining membrane performance and extending service life. The technology achieves turbidity removal exceeding 99% with minimal chemical addition requirements. Control systems monitor differential pressure, flow rates, and permeate quality to optimise cleaning cycles and predict maintenance needs. MF systems integrate seamlessly with upstream and downstream treatment processes, providing reliable barrier protection and consistent water quality improvement.
