ULTRA FILTRATION (UF) SYSTEM

Water Softning

Ultra filtration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients leads to a separation through a semi permeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentive, while water and low molecular weight solutes pass through the membrane in the permeate. This separation process is used in industry and research for purifying and concentrating macromolecular solutions, especially protein solutions. Ultra filtration is not fundamentally different from micro filtration, nano filtration or membrane gas separation, except in terms of the size of the molecules it retains - it is defined by the Molecular Weight Cut Off (MWCO) of the membrane used. Ultra filtration is applied in cross-flow or dead-end mode. Drinking Water drinking water

UF can be used for the removal of particulates and macromolecules from raw water to produce potable water. They have been used to either replace existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems employed in water treatment plants or as standalone systems in isolated regions with growing populations. When treating water with high suspended solids, UF is often integrated into the process, utilizing primary (screening, flotation, and filtration) and some secondary treatments as pre-treatment stages. UF processes are currently preferred over traditional treatment methods for the following reasons:

  • No chemicals required (aside from cleaning)
  • Constant product quality regardless of feed quality
  • Compact plant size
  • Capable of exceeding regulatory standards of water quality, achieving 90-100% pathogen removal
  • UF processes are currently limited by the high cost incurred due to membrane fouling and replacement. Additional pretreatment of feed water is required to prevent excessive damage to the membrane units.

In many cases UF is used for pre filtration in reverse osmosis plants to protect the RO.

“ION SAFE” high performance ultra filtration are designed with inside – out flow configure, the inside surface of the capillary. Membrane remains completely clean during the manufacturing process, providing uniform fiber structure. The plant are defect free low, low folding tendency, robustness and high surface integrity throughout the fiber. “

Ultra filtration, like reverse osmosis, is a cross-flow separation process. Here liquid stream to be treated (feed) flows tangentially along the membrane surface, thereby producing two streams. The stream of liquid that comes through the membrane is called permeate. The type and amount of species left in the permeate will depend on the characterizes of the membrane, the operating conditions, and the quality of feed. The other liquid stream is called concentrate and gets progressively concentrated in those species removed by the membrane. In cross- flow separation, therefore, the membrane itself does not act as a collector of ions, molecules, or colloids but merely as a barrier to these species

Custom Built Integrated Como-site Plant Consists of Ultra Filtration + Reverse Osmosis + Ultraviolet are also available.
