Microfiltration is a physical separation process. The extent to which turbidity and micro-organisms are removed is determined by the size of the pores in the membranes. When pressure driven fluid flows through a membrane micron sized particles separates from fluid and the process is called Microfiltration. Microfiltration is generally defined to be the filtering of a suspension containing colloids or fine particles in the approximate range of 0.1-10 micron. This size range contains a wide variety of natural and industrial particles such as, silt, viruses, bacteria, clay, colloidal silica, carbon black, paint pigment, yeast cells etc. Micro filtration is a pressure-dependent processes, where large particles get separated from smaller ones along with dissolved solids.

Ultrafiltration is a membrane process with the ability to separate molecules in solution on the basis of particle size. Ultrafiltration is typically rated by molecular weight cutoff. Ultra filtration can also be applied for pre-treatment of water for nano filtration or Reverse Osmosis. The pores of ultra filtration membranes can remove particles of 0.01 – 0.1 µm from fluids. Ultrafiltration (UF) membranes are able to separate colloids, suspended solids, emulsions, metal hydroxides, bacteria, viruses, emulsified oils, dispersed material and other large molecular weight materials from water and other solutions.

It is a solute-solvent separation process that uses a dense asymmetric semi-permeable membrane that is highly permeable to water and highly impermeable to solutes. A pressurized feed solution is passed over one surface of the membrane. As long as the applied pressure is greater than the osmotic pressure of the feed solution, “pure” water will flow from the more concentrated solution to the more dilute through membrane. RO membrane is widely used to remove salts from seawater or brackish water. RO membranes can remove solutes in the 0.0001 to 0.1 micron size range.

Ultrafiltration is a membrane process with the ability to separate molecules in solution on the basis of particle size. Ultrafiltration is typically rated by molecular weight cutoff. Ultra filtration can also be applied for pre-treatment of water for nano filtration or Reverse Osmosis. The pores of ultra filtration membranes can remove particles of 0.01 – 0.1 µm from fluids. Ultrafiltration (UF) membranes are able to separate colloids, suspended solids, emulsions, metal hydroxides, bacteria, viruses, emulsified oils, dispersed material and other large molecular weight materials from water and other solutions.

Appropriate pre-treatment to the feed stream is essential for success of the membrane system and hence given utmost priority while designing a membrane plant. Clariflocculator, HRSCC, dual media filter, tube settler, PSF, CF, specially designed cartridge filter along with suitable dosing and back washable UF are used.

GMS provides mixed bed units to suit all of our customers requirements. Cation and Anion resins are combined in a MSRL vessel to produce ultra pure water. Usually a mixed bed unit contains strong acid Cation (SAC) resin and strong base Anion (SBA) resins combined to a ratio of approximately 40% Cation resin to 60% Anion resin. GMS can install mixed bed units after a standard Reverse Osmosis, to produce ultra high quality water. The Cation resins in our mixed bed units are of a higher specific gravity and settle at the bottom of the vessel whilst the Anion resin will automatically float to the top.

Best membrane modules depending upon its geometry, chemistry, inter membrane space are selected for the membrane system for trouble free long lasting performance. GMS provides ceramic membrane for MF in tubular configuration. GMS encourages customers to buy membranes directly from the manufacturers.

GMS provides service to its customers through evaluation of Chemicals in use and studying the problem faced in a particular scenario. Based on its evaluation GMS advices usage of Generic chemical or a particular formulation which ever is effective and cheap.

GMS has deep social commitments and tries to contribute towards providing safe drinking water to villagers at affordable price. GMS has installed RO plants for rural drinking purposes in water scares areas of Gujarat.  In order to provide safe drinking water to villagers GMS has developed very cheap Hand operated RO plant which can deliver safe drinking water at three paisa per liter in remote areas. The Hand Operated RO plant has proved to be a boon in areas where water is contaminated with arsenic and/or fluoride which can not be removed by boiling. The operation of the plant is very simple and therefore can be operated by anyone. It does not require any maintenance except for some cleaning and membrane replacement.

Nano filtration is a technique that has succeeded in the course of recent years which is used most often with low total dissolved solids water such as surface water and fresh groundwater. Divalent and larger ions are generally targeted to be removed by Nanofiltration. Monovalent ions pass through Nanofiltration membrane so it is widely used for desalting application. Removing hardness and dissolved organics from water, arsenic removal from drinking water, heavy metal ions recovery from electroplating wastewater and separation of pharmaceuticals from fermentation broths are some of the examples of industrial applications of nanofiltration. NF has properties that lie between Ultrafiltration (UF) and Reverse Osmosis (RO) with pore size of 0.01-0.001 µm. Since all NF membranes have their origins in reverse osmosis (RO) membranes, they are called loose reverse osmosis membranes or tight ultrafiltration membranes with respect to its permeate flux and separation performance.
