Softeners
Softeners: Used for removal of hardness. Hardness of water is due to the presence of dissolved salts in water.
Temporary Hardness: Temporary hardness of water is due to the presence of bicarbonates of calcium and magnesium. Ca(HCO3)2 and Mg(HCO3)2.
Permanent hardness: Permanent hardness of water is due to the presence of chlorides and sulphates of calcium and magnesium (CaCl2, CaSO4, MgCl2,MgSO4.
Softeners are available in semi automatic and manual models for all your softening requirements.

- Textiles mills
- CETP’s and Lechate treatment plants
Leachate treatment plants (LTP)
A leachateis any liquid that, in the course of passing through matter, extracts soluble or suspended solids, or any other component of the material through which it has passed. The most common method of handling collected leachate is on-site treatment. When treating leachate on-site, the leachate is pumped from the sump into the treatment tanks.
The objective of the LTP is to stabilize the decomposable organic matter present in the domestic landfill so as to produce an effluent and sludge, which can be disposed of into the environment without causing health hazard and nuisance.
- LTP at kottayam municipality, kerala
- LTP at kohima municipality, nagaland. Work under progress.
ZLD (Zero liquid discharge)
Zero liquid discharge system ensures essentially no discharge of pollutants into the environment, and in this process, recovery of water gains primary importance. This recovered water can be reused. Zero discharge system consists mainly of strippers, multiple effect evaporators, and agitated thin film dryer (ATFD) among other equipment
Steam stripping modular system:
Steam stripping is used to remove various organic contaminants from plant waste water in order to meet guidelines set by pollution controlling agency. The organics and steam from the top of the column are then condensed and separated using a decanter. The condensed steam is refluxed to the top of the column.
The system is used for treating the high TDS/ high COD stream effluent is fed to the solvent stripper to minimizing low boiling solvents from the feed of the evaporator by maintaining temperature 90 degrees. The low boiling solvent vapor condensed by passing through condensers. Mixed solvent is collected separately in solvent collection vessel.
Multiple effect evaporation plant
Multiple effect evaporator is an apparatus for efficiently using the heat from steam to evaporate water to concentrate dissolved salts in the water. In multiple effect evaporator, water is boiled in sequence of vessels, each held at lower pressure than the last. As boiling of water decreases with pressure, vapor produced in one vessel can be used to heat the next vessel. Only first vessel requires the source of external heat.
Advantages:
- Ease of operation
- Most proven system for evaporation
For better energy utilization, the following are used: Multi effect evaporation using thermal vapor recompression (TVR), evaporation with mechanical vapor recompression.
Solvent stripped effluent shall be fed to the MEE along with RO rejects for further evaporation to get product of 30% solids. Four effect evaporator with each of the calendria forced circulation type. Each calendria shall be provided with separate vapor separator. Water vapor condensed in condensers and collects separately for further treatment in ETP.
The evaporation process itself involves both a thermodynamic and mass transfer phenomena. The thermodynamic phenomenon of evaporation involves providing enough heat energy (waste oil, off-spec gas, natural gas, propane, oil, diesel, electricity, or steam) to convert water to water vapor. The mass transfer phenomenon of evaporation can best be described as the “carry off” of small droplets of water.
Agitated thin film dryer (ATFD)
Thin film dryers are characterized by a mechanically agitated thin product layer inside the dryer (Fig. Thin Film Dryer). Normally, the drying process in a vertical thin film dryer consists of a preheating, a slurry and a powder zone. In the preheating zone the product reaches boiling point. Evaporation starts and solids are formed. In the slurry zone, the concentration of solids increases. Many products during this phase tend to form agglomerates which are crushed by the pendulum blades. In the final powder zone surface moisture is further removed and the drying process is completed.
The length of the various zones depends for a given product largely on the feed rates and feed moisture content.
The concentrated product from MEE is the feed to this system. The equipment consists of a cylindrical shell of jacketed for steam heating. The inside of the shell in is used for heat transfer surface. A Cylindrical rotor of rotating at a speed of 150 rpm shall be mounted inside the shell. Concentric with the shell axis. Teflon scrappers specially designed for evaporation in the initial portion and the drying at the bottom portion. The vapors generated shall be discharged to the surface condensers from the top of the dryer. The thick sludge of the product shall be discharged at the bottom.
