membrane filtration

Membrane Filtration

Membrane filtration is a technique that uses a physical barrier, a porous membrane or filter, to separate particles in a fluid. Particles are separated on the basis of their size and shape with the use of pressure and specially designed membranes with different pore sizes. When pressure is introduced to the membrane, water and low molecular weight substances are forced through the membrane as larger particles and molecules are rejected. As the rejected particles collect in the membrane, the system automatically backflushes rejected contaminants to a holding tank or into the sewer system.

SageGuard Solutions offers four levels of membrane filtration:

Tubular, spiral wound and hollow fiber membranes available.


ultrafiltration

Ultrafiltration

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 affect the purification efficiency. Ultrafiltration pore ratings range from approximately 1K to 500K D, making ultrafiltration more permeable than nanofiltration. The tangential flow of ultrafiltration such as hollow-fiber allows for the effective removal of colloids, proteins, bacteria, pyrogens, and other organic molecules larger than the membrane pore size.


Reverse Osmosis

Reverse osmosis is a method for treating water and wastewater in order to reduce dissolved solids or “salts” in the effluent discharge. This technology is used globally in drinking water and industrial applications. The process involves applying pressure to the influent water stream to overcome osmotic pressure and reverse the natural osmosis process. This process removes 95-99% of TDS (total dissolved solids), organic matter, bacteria and 99%+ of all suspended solids. Each system is custom designed for the application.
