Steel/ Power Plant/ Sugar/ Cement plants

We offer customised water Treatment system for Industries like steel, power, Sugar, Cement etc.

Clarifier system

RAPID CF works on two basic principles of Coagulation/Flocculation and Hydraulic Separation.


  • Waste Water Treatment
  • Heavy Metal Removal.
  • Colloidal Silica Removal


  • Compact design and easy operation
  • It handles high inlet suspended solids up to 3000 ppm
  • Reduction in chemical requirement
  • Consistent treated water quality less than 10 ppm for raw water & 30 ppm for waste water
  • Hydraulic separation takes place based on the principle of Stroke’s law to settle down the sludge
  • Coagulation and Flocculation occur in the draft tube and flocculation zone

Multi-grade Sand Filters

RAPID MGF is used for removal of suspended solids from Raw Water.

These filters can be operated at high specific flow rates upto 200 m3/hr. while treating water containing suspended solids up to 25ppm and producing treated water having suspended solids up to 5ppm.


  • Less space requires for operations, specific flow rate is higher than conventional filters.
  • Ease in maintenance.
  • Lower backwash water requirement hence saving in cost.

Activated Carbon Filter

RAPID ACF - Activated carbon filter is provided in order to remove colour, odour, free chlorine & organics to some extent. The activated carbon media is a very good absorbent which absorbs the free chlorine from filtered water. This unit is charged with an activated carbon bed, which is supported on layer of cylix and pebbles. Free chlorine, colour & Organics to some extent from filtered water is removed by activated carbon.


  • Grantee reduction of chlorine from water
  • Designed with ss plate Stainer
  • Coal based Activated Carbon with Iodine value <950
  • Carbon contact time 7.5 to 15 minute
  • Proven System for Removal of Colour, Odour, COD BOD.
  • Easy maintenance
  • Steam Sanitize-able

Iron Removal Filter (IRF)

RAPID IRF is Iron Removal Filters are used to remove the Excess Iron content present in the feed water

IRF systems works on the principal of oxidation of Iron to convert it from a dissolve ferrous in water to a ferric or undissolved state.

Converted ferrous to ferric state is precipitated on a filter bed

For low Iron content in feed water, IRF r consists of Manganese Zeolite for low iron content, where the iron is oxidized to insoluble hydrated oxides that are removed by the mechanical filtering action of the Zeolite bed.

Dual Media Filter (DMF)

RAPID DMF is a combination of MGF+ACF, this system is used for lower side load of suspended matters, taste, odour, and chlorination then MGF+ACF and the end product is clean water with no objectionable taste & suspended matters.on.


  • Drinking Water Treatment
  • Pre-treatment in RO process
  • Wastewater Treatment


Raw Water containing scale forming hardness is not desired by the industry.

Rapid SOFT use the proven technique of ion-exchange for producing treated water with low residual hardness.


  • Consistent treated water quality.
  • Longer operating cycles.
  • Lower Regeneration cost.
  • Simple to install and operate.
  • Specially designed against high residual hardness.

Ultrafiltration Systems

Most waters contain colloidal particles, organics and fine suspended solids resulting in high SDI (silt density index) which is harmful to downstream water treatment processes.

Ultrafiltration is the ideal cost-effective method for reduction of SDI and Colloidal silica. RAPID ULTRA comes in flow rates up to 200 m3/hrs as standard units.

  • High retention rate for particles, germs, bacteria and viruses.
  • Considerably smaller systems which use conventional flocculation and filtration.
  • Modular design.
  • Less work for the operating personnel due to fully automatic operation.
  • Continuous Operation. & Low maintenance

Reverse Osmosis Systems

Reverse Osmosis successfully treats water with dissolved minerals and metals such as aluminium, arsenic, barium, cadmium, chloride, chromium, copper, fluoride, magnesium, iron, lead, manganese, mercury, nitrate, selenium, silver, sulphate, and zinc with the recovery of 85-90%. Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration.

Rapid SOFT use the proven technique of ion-exchange for producing treated water with low residual hardness.


  • Continuous process.
  • Low energy consumption.
  • High recovery.
  • Skid Mounted Plug & Play System.
  • Automatic & Manual Process (As per the client requirement).
  • With PQ (Performance Qualification).

Degasser System

RO system does not remove gas which was generated during reverse osmosis Water from RO unit outlet feeds in to de-gasser tower for removal of free carbon-dioxide in the feed water. De-gasser tower is a forced draft type atmospheric tower fitted internally with a top distributor plate and bottom collector plate. Polypropylene pall rings are filled in the tower to sprinkle water where carbonic acid dissociated in carbon dioxide and water, carbon dioxide removes by upper vent.

DM Plant

Raw Water containing dissolved solids is not desired by the industry.
RAPID DE-MINERIALIZATION use the proven technique of ion-exchange for producing treated water with low residual dissolved solids.

A strongly acidic Cation exchanger in Hydrogen form is used to exchange Hydrogen ions for sodium, calcium and magnesium, the cations, producing de-cat ionised water. This de-cat ionised water is fed to a column containing strongly basic Anion exchanger in Hydroxyl form. Here the anions i.e., chlorides sulphates are exchanged for the Hydroxyl ion, producing demineralised water suitable for the industry. The resins are regenerated with hydrochloric acid and the anion with sodium hydroxide at the end of each cycle. To further improve the quality of treated water, it is passed through single bed of cation and anion exchanger in mixed form.


  • Consistent treated water quality.
  • Lengthier operation cycles.
  • Minimise Re-generation cost.
  • Easy to Install and operate.


  • Boiler feed.
  • Food and beverage industry.
  • Pharmaceutical and chemical industry.
  • Electronic industry.
