Membrane Based System
Micro Filtration (MF Membranes)
Tilted / Corrugated plate Interceptors are gravity separators which utilize the difference in specific gravity between two phases of liquid (predominantly for removal of free oil in water) as the principle of separation. The high surface area for separation is provided by a lamellar arrangement of plates which also reduces the plot space requirement.
Paramount Limited designs & constructs Tilted / Corrugated plate Interceptors with technology acquired from M/s. PWT, Holland.

Microfiltration (MF) is a process which removes suspended & colloidal impurities from the liquid by passing it through a micro porous membrane, physically excluding particulate matter.
Microfiltration is a low-pressure cross-flow & dead end membrane process for separating colloidal and suspended particle. MF is used for fermentation both clarification and biomass clarification and recovery. Low pressure membranes were selected to remove turbidity and pathogens without chemical conditioning. Low pressure microfiltration membranes have become more popular & hence, it is being used for difficult waters, containing more solids, turbidity and higher levels of dissolved organics. Depending on the feed characteristics, some of these waters require chemical pretreatment such as pre-chlorination etc.
This technology is now being used for water treatment and wastewater treatment in the pretreatment of Zero Liquid Discharge system (ZLD).

Ultra Filtration (UF Membranes)
Paramount Limited provides ultra filtration membrane system. We manufacture skid mounted ultra filtration membrane systems of all capacity. Paramount offers pilot plan trials to check the suitability of ultra filtration membrane system for water, wastewater & process applications in all industries. One such installation has been for pigment industry where Paramount Limited provided the system with a flow of 14,400 cubic meters per day as pretreatment to RO system for recycling of Cooling Tower Blow Down (CTBD) water.
Ultrafiltration works using hydrostatic pressure to force the liquid against a semi-permeable membrane, often utilizing cross-flow membrane filtration. Water and low molecular weight compounds come in permeate through the membrane, whilst suspended solids and high molecular weight compounds remain as a reject. UF membranes are typically classified by their ability to retain solutes of a specific size, with Molecular Weight Cut-Offs (MWCO) ranging from 100,000 daltons to 1500 daltons.
Ultrafiltration is used in a lot of applications in a different segment of industries like chemical, pharmaceutical, food, pretreatment of RO & wastewater treatment. UF can be used in process applications as well as in recycling of treated wastewater based on the feed parameters. Ultrafiltration (UF) is used to remove essentially all colloidal particles (0.01 to 1.0 microns) from water and some of the largest dissolved contaminants. The pore size in the UF membrane mainly determines the type and size of contaminants being removed.
A major attraction of UF is the ability to purify, separate, and concentrate target macromolecules in continuous systems.

Nano Filtration (NF Membranes)
Paramount Limited provides Nanofiltration membrane system. We manufacture skid mounted Nanofiltration membrane systems of all capacity. Paramount offers pilot plan trials to check the suitability of Nanofiltration membrane system for water, wastewater & process applications in all industries. Paramount Limited has installed several Nanofiltration membrane system for Dye desalting & concentration. Using this technology, Paramount Limited has achieved Zero Liquid Discharge in distillery units. It was used for the treatment of spent wash at the outlet of biodigester having COD & BOD as high as 55,000 ppm 8,000 ppm respectively.
Nanofiltration (NF), in concept and operation, is more or less similar to reverse osmosis (RO). The main difference is the percentage of removal of salts & its operating pressure. Nanofiltration (NF) allows the monovalent ions to pass through the membranes such as chlorides. Nanofiltration (NF) removes 40% to 90% of monovalent ions, depending on the material and manufacture of the membrane; whereas RO Membrane, at higher operating pressure, rejects all kind of salts between 95% to 99% depending on the type of salts.
Nanofiltration technology is a crossflow membrane filtration which rejects particles in the approximate size range of 1 nanometer. Nanofiltration (NF) falls between Ultrafiltration (UF) and Reverse Osmosis (RO) Membranes.
Organic molecules with molecular weights greater than 150 daltons are rejected in Nanofiltration (NF). Also, dissolved salts are rejected in the range of 20-98% depending on type and concentration of salts. Typical applications of Nanofiltration (NF) include removal of color, total organic carbon (TOC) & hardness from water. Also, the overall reduction of total dissolved solids (TDS) occurs within the process.
Nanofiltration (NF) is being used for separation of organic & inorganic mixtures. Nanofiltration membranes are also used for desalting or deashing application These membranes allows chlorides to pass through the membrane in permeate and product remain in the concentrate. Nanofiltration (NF) membranes are sometimes referred to as softening membranes due to their ability to reject calcium and magnesium. Nanofiltration (NF) membranes also remove sulphate from the water.

Reverse Osmosis
Reverse osmosis (RO) is a separation process that uses pressure to force a solvent through a semi permeable membrane. Impurities in the solvent are excluded, whilst pure solvent passes through the membrane. In other words, it is the process of forcing a solvent from a region of high solute concentration through a semi permeable membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process.
Reverse Osmosis Technology is the tightest possible membrane process in liquid separation. In most cases the membrane is designed to allow only water to pass through the membrane while rejecting the salts. This process requires high pressure at the high concentration side of the membrane, Normally the operating pressure range is 8-60 bar depends on the type of water like fresh, brackish & sea water.
The RO membrane acts as a barrier to all dissolved salts and inorganic molecules as well as organic molecules with a molecular weight greater than approximately 100 daltons. Rejection of dissolved salt is typically 95 to 99%.
Paramount Limited provide the most economical process for desalination of brackish water and sea water. The system allows further integration with pre & post treatment such as media filters clarifier, microfiltration (MF), Ultrafiltration (UF) in the pretreatment side and ultra-violet sterilizer and chlorination system, degasser & pH correction are the part of post treatment. However, there are numerous other applications in the chemical, pharmaceutical, and food industry, as well as in effluent water recycling applications.
