Water Treatment Plants

Reverse osmosis (RO) is membrane separation process that removes dissolved ionic solids. Reverse osmosis is the process of pushing a solution through a filter that traps the solute on one side and allows the pure solvent to be obtained from the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure .The membrane here is semi permeable, meaning it allows the passage of solvent but not of solute. The water goes into solution in the polymer of which the membrane is manufactured, and crosses it by diffusion .This process requires that a high pressure be exerted on the high concentration side of the membrane.

Ultra filtration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semi permeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. Ultrafiltration is not fundamentally different from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains.

Desalination is a process that removes dissolved minerals from seawater, brackish water ,or treated wastewater. A number of technologies have been developed for desalination ,including reverse osmosis (RO), distillation, electro dialysis and vacuum freezing Two of these technologies ,R0 and distillation are mostly being used all over the world.

Nanofiltration is a special process selected when RO and UF are not the ideal choice of separation. NF can perform separation applications that are not otherwise economically feasible, such as demineralization, color removal and desalination In concentration of organic solutes ,suspended solids, and polyvalent ions ,the permeate contains monovalent ions and low-molecular-weight organic solutions like alcohol.

Carbon filtering is commonly used for water purification and also used in air purifiers. Carbon filters provide fresh water and are easy to operate. These filters are most effective at removing chlorine, sediment, and volatile organic compounds (VOCs) from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds. The particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres. The efficacy of a carbon filter is also based upon the flow rate regulation. Carbon filters are used in individual homes as point-of-use water filters and also used as pre-treatment devices for reverse osmosis systems. Further, these filters are appreciated for their durability, simple installation and reliable performance.

Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. The industrial filter works on principle of retention and removal of physical impurity in a graded manner through voids of the filtering media. Industrial filters use advance technology and high quality equipments for filtration. These filters are used in various industries like Oil and Petroleum, Pharmaceutical, Refrigeration and Air Filtration, etc. Selection of filters depend upon various factors that include piping size, operating temperature, maximum flow rate, minimum and maximum operating pressure, contaminants to be removed, degree of filtration desired, etc. Moreover, these filters are highly acknowledged for their salient features that include durability, high efficiency, smooth functioning, reasonable prices, etc.

Water softeners are used to remove the hardness of water and imparting impurities. Water softening is the reduction of the concentration of calcium, magnesium, and other ions in hard water. These "hardness ions" can cause a variety of undesired effects including interfering with the action of soaps, the build up of limescale, which can foul plumbing, and galvanic corrosion. Water Softeners that are used in homes are depend on an ion-exchange resin in which hardness ions are exchanged for sodium ions. Water softening may be desirable where the source of water is hard. However, hard water also conveys some benefits to health by providing dietary calcium and magnesium and reducing the solubility of potentially toxic metal ions such as lead and copper.

Demineralization is the removal of minerals and mineral salts from water. Demineralization Plants use latest technology and are effectively used for removing mineral salts from water by using the ion exchange process. These plants exchange all cations and anions during Ion Exchange process, which consists of either twin bed or with mixed bed polisher. The charged resins exchanges hydrogen (H+) ions with all cations and hydroxyl (OH?) ions with all anions to de-ionize the water. These are widely used in applications like pharmaceutical plants, medical facilities, dialysis centers, and other industrial applications.

Sewage is waste water released by residences, businesses & industries. Our precision designed and developed sewage treatment plants help in reducing or removing organic matter, solids, nutrients, disease-causing organisms and other pollutants from waste water. The offered plants are designed to deliver superior physical separation of solids from raw waste water stream. This is followed by progressive conversion of dissolved biological matter in solid biological mass using indigenous, water - borne bacteria.

Once the biological mass is separated or removed, the treated water may undergo additional disinfection via chemical or physical processes This final effluent can then be discharged or re-introduced back into a natural surface water body (stream, river or day) and the water is further treated to be used for horticulture flushing, cooling towers & other auxiliary purposes.

The various stages of treatment are as
Screening & Equilisation
Waste water will flow through a bar screen chamber & oil & grease trap where large particles ,oil & grease is separated .The equalization tank is provided to nuetralise the peak flows and maintain a constant flow of plant.

Aeration
From the equalization tank , The waste is transferred to the aeration tank where it will be mixed with living organisms also called MLSS (Mixed Liquor Suspended Solids) in presence of air. The aeration system shall be designed in a way so as to achieve complete mixing of organisms with raw sewage.

Clarifications
From the aeration tank this mixed liquor passes into the secondary clarifier where the excess sludge is separated from the liquid.

Disinfection
The addition of a chlorine solution kills any pathogenic microscopic life,such as bacteria or viruses.

Filtration
Any remaining particles are trapped and removed during filtration. The almost clear water from the aeration tank is pumped into the pressure filters containing anthracite and activated carbon.

Kinds of Plants
FAB ( Fluidized Aerobic Bed)
MBR ( Membrane Bio Reactor)
MBBR (Moving Bed Bio Reactor)
SAFF (Submerged Aerobic Fixed Film)
SBR (Sequence Batch Reactor)
Extended Aeration
