Ultra Filtration Skid Packages
Ultra Filtration is a pressure‐driven membrane process that removes suspended matters from aqueous mediums like water. UF membrane has pore sizes range from 0.01to 0.1um.
The fine pores form an ideal physical barrier to remove impurities while allowing water molecules to pass through. The smaller the nominal pore size, the higher the removal efficiency. 
Parasites, bacteria, viruses, colloidals and suspended matters are effectively removed by UF membranes. The result is clean and clear permeate, water that is ready for use or further treated for process needs. Most materials that are used in UF are polymeric, such as polysulfone (PS), polyethersulfone (PES), polypropylene(PP), or polyvinylidenefluoride (PVDF).
Origin Water's Ultra-Spring UF membrane is made from high‐grade polymeric PVDF material to form a hollow fiber membrane that is very durable and less prone to breakage as some of the other materials exhibt. The hollow fiber has a dense layer and a skin on the outside surfaces, forming a asymmetric structure that contributes to its strength. Our proprietary asymmetric hollow fiber PVDF membrane provides excellent mechanical strength, greater elasticity and superb chemical compatibility. Our membrane with uniform pore size distribution characteristics produces very high quality filtrate (product water) that generally required no coagulants prior to the membrane. Turbidity of filtrate is usually much below 0.1NTU.

 The Work Principles of Ultra-Spring UF

Ultra-Spring UF modules utilize a Single‐walled, Asymmetric, Sponge‐like (no finger void) structure hollow fiber PVDF membrane with a very small uniform pore diameter for excellent removal of particulate matter and bacteria, and most viruses and colloids. Despite the small pore diameter, the membrane has a very high porosity, resulting in a stabilized flux similar to that of micro‐filtration(MF).

Typically, Ultra-Spring membranes are operated at a constant permeate flow. The transmembrane pressure (TMP) will naturally increase over time, and the module can be cleaned by back‐washing and air‐scouring to remove the fouling layer for longer service life.


Ultra filtration (UF) Membrane Skid Systems 


Ultra Filtration Skid System



With the professional knowledge and solid engineering experiences of membrane separation, we can provide the standard and custom UF Membrane skid to the clients site requirements.

Looks Smart, Performance Perfect!

Origin Water's Ultra filtration Systems are based on outside-in flow configuration ultra filtration modules, which allow for less plugging, higher solids loading, higher flow area and easy cleaning. The primary flow design is dead-end filtration which uses less energy and has a lower operating pressure than the concentrate bleed, therefore reducing operating costs. Our standard systems are designed for reliable, long term trouble free operation, with straight forward control.
