Ultrafiltration is a pressure-driven purification process in which water and low molecular weight substances permeate a membrane while particles, colloids, and macromolecules are retained. The primary removal mechanism is size exclusion, although the electrical charge and surface chemistry of the particles or membrane may also affect the purification efficiency.
Ultrafiltration pore sizes range from approximately 1K to 500K daltons, thereby making ultrafiltration more permeable than nanofiltration (200 – 1000 daltons). The tangential flow of Hollow Fiber ultrafiltration allows the effective removal of colloids, proteins, bacteria, pyrogens (e.g., gram-negative bacteria), and other organic molecules larger than the membrane pore size.
Advantages of using Porelogix Ultrafiltration Systems over Traditional Filtration Technology (Clarification, Gravity filtration, Cartridge & Bag filtration)
- Ultrafiltration will eliminate bacteria, pathogens, viruses
- Ultrafiltration will provide consistent higher quality permeate
- Compact skid-based system design reduces footprint and increases mobility
- Touchscreen controls and interface designed for simplicity and effectiveness
- High degree of variation and combination for mechanical and chemical cleaning
The biggest advantage for utilizing Ultrafiltration over traditional technology is the fact that regardless of the degree of contamination of the original feed water source, the permeate from Ultrafiltration will always remain the same level of superb purity. Traditional Filtration technologies cannot match the membranes efficiency.
