WATER TREATMENT

Water treatment includes removing impurities such as sand, suspended solids, dissolved salts, ions, hardness from natural water bodies for its use in industries and households. With stringent pollution and specific water quality requirements for industries, it is necessary to treat water from various sources for further uses.

Chemical Dosing

Chemical dosing is the adding of chemicals into water/fluid or sludge to achieve required conditioning. This would make the treatment effective by various mechanisms such as charge neutralisation, settling of solids etc.

Clarifiers

Clarifiers are the settling tanks used to separate solid particulates from liquids.

Filters

Filtration is a process to remove finer impurities from water by using a physical barrier.

Softeners

Softeners are widely used for reducing hardness from water. Softening is a reversible ion exchange process wherein the hardness forming ions are exchanged with sodium ions present in the resin group.

Demineralisation (DM)

Demineralisation is the most proven and reliable technology used in water treatment to remove minerals, using the principles of ion exchange. De-gasification & polishing are used to produce mineral-free water.

Membrane Filtration

Reverse osmosis (RO), Nanofiltration (NF), Ultrafiltration are membrane filtration based processes used for separation of dissolved salts. Water is pumped against the surface of a membrane resulting in separation of dissolved constituents.

WASTEWATER TREATMENT

Various constituents get added in water after its use and water becomes wastewater. Wastewater treatment processes remove those constituents as organics, solids, heavy metals etc. Wastewater include mainly industrial wastewater and domestic sewage. Wastewater treatment plants are designed using a combination of physical, chemical and biological processes, so that treated water could be discharged in the environment or reused further.

ZERO LIQUID DISCHARGE

Zero Liquid Discharge is a wastewater recycling process used to limit liquid waste. As the name indicates ‘Zero Liquid Discharge’ the aim is to remove all liquid waste from the system. The conventional way is to reach ZLD with thermal technologies such as evaporators like Multi Effect Evaporation (MEE), Mechanical Vapour Compression (MVC) and Agitated Thin Film Dryer(ATFD). Many Industries are considering ways to reduce their water discharges with Zero Liquid Discharge technology. Implementation of the ZLD system increases the cost of production, but water scarcity & strict norms are the key drivers for ZLD installations.

DESALINATION

Desalination processes separate dissolved salts and other minerals from seawater. The process operates at high pressure and the water is ideal for industrial application. Water for human consumption can also be produced . Feedwater may include brackish water, seawater, wells, surface (rivers and streams), wastewater, and process waters. Membrane separation requires driving force which is provided by a high pressure pump. We have several successful installations that also incorporate energy recovery systems to improve the returns from the system. With the rising cost of freshwater and its growing scarcity, the economical treatment of seawater treatment offers the possibility of bridging the demand supply gap.
