Reverse Osmosis Brackish Water

Reverse Osmosis Technology

Reverse Osmosis is a water purification technology that uses a semipermeable membrane to remove larger particles from drinking water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property,that is driven by chemical potential,a thermodynamic parameter. 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. In the normal osmosis process, the solvent naturally moves from an area of low solute concentration (high water potential), through a membrane, to an area of high solute concentration (low water potential). The movement of a pure solvent is driven to reduce the free energy of the system by equalizing solute concentrations on each side of a membrane, generating osmotic pressure. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis.

Performance
A single stage of Reverse Osmosis elements typically reduces the level of raw water salts, colloids, organics, bacteria, and Endotoxin by 90 to 99%. Single stage Reverse Osmosis product water does not normally meet the requirements of the USP without further purification steps. Some two-pass units (two sets of RO membranes in series) produce water that can pass the USP25NF20 conductivity requirements, allowing On-Line testing. Membrane selection should be based upon pre-treatment requirements, operating performance characteristics, sanitisation options, warranties, capital and operating costs, and the feed water source.

Advantages :
- Reverse Osmosis units eliminate or significantly reduce chemical handling and disposal, relative to regenerable ion exchange systems.
- Generally, RO has more effective microbial control than ion exchange systems.
- Integrity testing can be accomplished by salt challenge and measurement of differential conductivity.
- RO removes a wide variety of contaminants including ionised solids and non-ionic materials (e.g., colloids, bacteria, Endotoxin,and some dissolved organics).

Ultrafiltration Technology

Ultrafiltration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. A semipermeable membrane is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed for removal of bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts. As advancements are made in membrane production and module design, capital and operating costs continue to decline. Ultrafiltration uses hollow fibers of membrane material and the feed water flows either inside the shell, or in the lumen of the fibers. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. Performance UF is utilised to remove a variety of contaminants. The proper UF membrane must be selected to meet the performance requirements.Organic molecules can be rejected well, but the rating of UF membranes varies in molecular weight cut-offs from 1,000 to 100,000. Reduction of typical raw water organics is not as effective as Reverse Osmosis. Pressure drops vary with membrane selection and operating temperature. Some UF membranes are capable of continuous operation at temperatures up to 90ºC, to provide excellent microbial control. UF reduction of Endotoxin (pyrogens) varies from 2 log10 to 4 log10 as a function of membrane selection. UF has been shown to be capable of consistent production of purified water meeting the USP WFI Endotoxin limit of 0.25 Eu/ml in typical system applications. UF produces excellent microbial reduction with typical ratings of 3 log10 to 4 log10 reduction. UF produces excellent particle reduction and is frequently used in other applications, such as semiconductor production when particle control is far more critical than purified water.

Advantages:
- UF can remove contaminants, such as Endotoxin and organics.
- UF offers effective operating costs in high particle loading applications.
- Some UF elements can tolerate rigorous sanitisation procedures using steam or ozone.
- The waste stream is generally much less than waste from Reverse Osmosis units.

Waste Water Treatment

WASTE WATER TREATMENT WITH AOP SYSTEMS

Advanced Oxidation Process(AOP) in board sense, refers to a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and waste water by oxidation through reactions with hydroxyl radicals (•OH). In real-world applications of wastewater treatment, however, this term usually refers more specifically to a subset of such chemical processes that employ ozone (O3), hydrogen peroxide(H2O2) and/or UV light.

A goal of the waste water purification by means of AOP procedures is the reduction of the chemical contaminants and the toxicity to such an extent that the cleaned waste water may be reintroduced into receiving streams or, at least, into a conventional sewage treatment.

AOPs hold several advantages that are unparalleled in the field of water treatment:
- It could effectively eliminate organic compounds in aqueous phase, rather than collecting or transferring pollutants into another phase.
- Due to the remarkable reactivity of •OH, it virtually reacts with almost every aqueous pollutants without much discrimination. AOPs could therefore be applicable in many, if not all, scenarios where many organic contaminants are expected to be removed at the same time.
- Some heavy metals could also be removed in forms of precipitated M(OH)x.
- In some AOPs designs, disinfection could also be achieved, leading AOPs to an integrated solution to some of the water quality problems.
- Since the complete reduction product of •OH is H2O, AOPs theoretically do not introduce any new hazardous substances into the water.

Ion Exchanger

ION EXCHANGER

Ion exchange is a reversible chemical reaction where an ion (an atom or molecule that has lost or gained an electron and thus acquired an electrical charge) from solution is- exchanged for a similarly charged ion attached to an immobile solid particle. These solid ion exchange particles are either naturally occurring inorganic zeolites or synthetically produced organic resins. The synthetic organic resins are the predominant type used today because their characteristics can be tailored to specific applications. An organic ion exchange resin is composed of high-molecular-weight polyelectrolytes that can exchange their mobile ions for ions of similar charge from the surrounding medium. Each resin has a distinct number of mobile ion sites that set the maximum quantity of exchanges per unit of resin.

Most plating process water is used to cleanse the surface of the parts after each process bath. To maintain quality standards, the level of dissolved solids in the rinse water must be regulated. Fresh water added to the rinse tank accomplishes this purpose, and the overflow water is treated to remove pollutants and then discharged. As the metal salts, acids, and bases used in metal finishing are primarily inorganic compounds, they are ionized in water and can be removed by contact with ion exchange resins.

In a water deionization process, the resins exchange hydrogen ions (H+) for the positively charged ions (such as nickel. copper, and sodium). and hydroxyl ions (OH-) for negatively charged sulfates, chromates. and chlorides. Because the quantity of H+ and OH ions is balanced, the result of the ion exchange treatment is relatively pure, neutral water.

This technology offers a number of advantages in industrial water demineralization and softening, wastewater recycling and other water treatment processes-including high water recovery, low volume of waste and operational flexibility.

Ion exchange resins are also used in a variety of specialized applications such as chemical processing, pharmaceuticals, mining, and food and beverage processing.

Oxygen Generator

Oxygen Generator

OXYGEN GENERATOR Air contains 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% other gases. Oxygen Generating Systems separate oxygen from compressed air through a unique Pressure Swing Adsorption (PSA) process. The PSA process uses molecular sieve (a synthetic zeolite), which attracts(adsorbs) nitrogen from air at high pressure and releases (desorbs) it at low pressure. Oxygen Generators System use two vessels filled with molecular sieve as adsorbers. As compressed feed air flows through one of the vessels, the molecular sieve adsorbs nitrogen. The remaining oxygen passes through the vessel and exitsas the product gas. Before the adsorber becomes saturated with nitrogen, the feed air is diverted to the second vessel. At that point, the sieve in the first vessel regenerates by desorbing the nitrogen through depressurization and purging it with oxygen from the second vessel. This process is then repeated in the second vessel to complete a cycle that allows the oxygen generator to deliver a constant flow of product oxygen at 90% minimum purity. Under normal operating conditions, the molecular sieve is completely regenerative and will last indefinitely.
