1.Description of Ultrafiltration System RO plant water treatment machine

Ultrafilters (UF) can be obtained either as spirally wrapped membrane devices or as a bundle of hollow fibres. The nominal molecular cut-off (NMWCO) range for ultra filtration devices is between 5,000 and 150,000 Daltons.
They can be used in both pre-treatment and polishing duties in water purification systems. For pre-treatment a UF device with a (NMWCO) of between 80,000 and 150,000 Daltons would be used for the removal of colloidal contaminants. For the removal of Endotoxin material from purified water, the pore size would be reduced to between 5,000 and 20,000 Daltons.
To maintain performance, UF membranes will require frequent back-flushing and ocassional cleaning using chemicals. For critical applications, hot water can be used to thermally disinfect the membranes; this will depend on the materials of construction used in the UF membrane.

Our membrane filtration system uses advanced hollow fiber or ceramic technologies which operate in the outside-in or inside-out direction of flow. Given the small membrane pore sizes used with these technologies, fouling due to deposition of organic and inorganic compounds on the membrane may occur if the ultrafiltration system is not properly designed and operated. Therefore, we use automated backwashing, air scour and chemical flushing processes to restrict the rate of membrane fouling within acceptable limits. Chemical cleaning is employed once the maximum transmembrane pressure has been reached. Typical cleaning agents utilized include acids, caustic, surfactants, enzymes and certain oxidants, depending upon membrane material and fouling type.

Reverse osmosis can remove many types of molecules and ions from solutions, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.
