Areservoir is a natural or artificial storage pond which is used to storewater.

Aeration is a process that is used to remove unwanted gases from water. Cascade Aerators induct air into a water flow in order to oxidize iron and reduce dissolved gases.

CASCADE AERATOR

The stilling chamber is used to remove air bubbles from the liquid. Water flows to the Stilling Chamber to break the turbulence.

STILLING CHAMBER

As the liquid passes through the stilling chamber, its velocity becomes very low due to the large diameter of the stilling chamber. This permits the fine air bubbles in the liquid to rise to the top of the stilling chamber. The automatic air vent in the top of the stilling chamber removes the air as it collects at the top of the stilling chamber.As the liquid passes through the stilling chamber, its velocity becomes very low due to the large diameter of the stilling chamber.

Chlorine is a strong oxidizing agent. The effect of chlorine in water are:DisinfectionControl of algaeControl of the color and taste of water.

CHLORINATION

FLOW DIAGRAM

Reactions of Chlorine Gas with Water

When chlorine gas enters the water, the following reaction occurs:Chlorine + WaterHypochlorous Acid + Hydrochloric Acid Cl2+ H2OHOCl + HCl

Hypochlorous acid may further break down, depending on pH:Hypochlorous AcidHydrogen Ion + Hypochlorite Ion HOClH++ OCl-

ACTIFLO

ACTIFLO IS A COMPACT, CONVENTIONAL TYPE CLARIFICATION SYSTEM.IN ACTIFLO WE USE PHYSICAL, CHEMICAL TREATMENT, INCLUDING COAGULATION, FLOCULATION AND SETTLING TO GET CLARIFIED WATER.

BASKET FILTER NORMALLY USES A SCREEN MASH AS ITS FILTERING MEDIUM. ALSO USED FOR THE REMOVAL OF COARSE BULK SOLIDS (very fine insoluble particles).

Ultra filtration(UF) is a variety ofMembrane filtrationin which forces likepressure to separation through asemi permeable membrane. UF's main advantage to purify,separate, and concentrate targetmacromolecules in continuous systems.

TO REVERSE OSMOSIS PROCESS WE NEED TO APPLY ENERGY TO REMOVE SALINE SOLUTION.A REVERSE OSMOSIS MEMBRANE IS A SEMI PERMEABLE MEMBRANE THAT ALLOWS THE PASSAGE OF WATER MOLECULES, BUT NOT THE MAJORITY OF DISSOLVED SALTS, ORGANICS, BACTERIA & PYROGENS.

RO SYSTEM

Reverse osmosis is the process of forcing a solvent from a high solute concentration through a semi permeable membrane to low solute concentration by applying a pressure.

Electrode ionization (EDI)- Its a water treatment technology which utilizes electrodes for ionizing water molecules as well as separating dissolved ions (impurities) from water.ELECTRODEIONIZATION

Simple and continuous operationChemicals for regeneration completely eliminatedCost effective operation and maintenanceLow power consumptionNon pollution, safety and reliabilityIt provides complete removal of dissolved inorganic particlesIt removes more than 99.9% of ions from the water
