Waste Water Treatment Plant

Wastewater treatment is a process used to convert wastewater into an effluent (outflowing of water to a receiving body of water) that can be returned to the water cycle with minimal impact on the environment or directly reused. The latter is called water reclamation because treated wastewater can then be used for other purposes. The treatment process takes place in a wastewater treatment plant (WWTP), often referred to as a Water Resource Recovery Facility or a Sewage Treatment Plant

Zero Liquid Discharge(ZLD) Evaporator

Description: 

Zero Liquid Discharge consists of industrial wastewater treatment processes developed to totally wipe out all liquid discharge from the industrial facility.A zero liquid discharge is a procedure that is beneficial to industrial and municipal governing bodies as well as the environment because it saves money and no liquid effluent, are discharged from the facility. ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced

Features and Benefits: 
  • Zero Liquid Discharge(ZLD) is a series of processes (Like Membrane filtration, reverse osmosis, eveporation and crystallization) that extract pure water from industrial effluents, leaving behind sludge, dissolved solids, suspended particles and salt crystals.
  • Pre-requisite for ZLD needs physical and chemical treatment and followed by biological system to remove organic load.
  • The treated effluents can be subjected for concentration and evaporation.
  • The concentration method quite often involves the adoption of Reverse Osmosis (RO) and Nano Filtration(NF) methods.
  • The evaporation methods involve incineration/drying/evaporation of effluent in multi effect evaporatores(MEE).

Applications :

  • Beverage & Distillery Industry
  • Bakery & General Industries
  • Tobacco Industries
  • Honey Industries
  • Pharmaceutical Industries
  • Food Processing Industries
  • Ice Creams
  • Herbal Cosmetics
  • Ultra Filtration System
  • Reverse Osmosis System
  • Sea Water RO System for High TDS
  • Evaporation System

Need of ZLD :

  • Most polluting industries such as Pharma, Pulp & Paper, Tanneries, Textile, Dyeing, Chemicals, Power Plants etc. generate wastewater with high salinity/TDS.
  • Conventional 'Physico - chemical biological' treatment does not remove salinity from the treated effluent. The TDS content is well above the statutory limit.
  • Discharge of saline but treated wastewater pollutes ground and surface waters.
  • TN has taken a lead on ZLD due ti absence of fully flowing perennial rivers.
  • Main motivatord - Water Scarcity, water economics, regulatory pressure.

Forced Air Evaporator

Description: 

Forced Air Evaporator Unit is a solution for evaporation of water out of the rejected effluent with friendly environmental way. Generally at Lagoon, only Upper thin layer of water gets natural evaporation. Such quantity is much less as compared to generation of large quantity of effluent. Thus a requirement is felt by the Industry for faster and efficient mechanical solution. We have developed an evaporator unit such that very fine size of water particles are generated and are forced to mix with high volume of Air and are then flown in to the atmosphere to take advantage of evaporation in abundant quantity of atmospheric air.

Fans supplied with the refrigeration equipment are used to cool the air by forcing it past the evaporator coils. These fans are not large enough, nor are they properly located in most cases, to force air directly past the produce. Furthermore, the chilled air leaving the evaporator coils is generally much too cold for most types of produce. It must be mixed with the warmer air inside the room to prevent chill injury. Therefore, additional fans are required to move the air past the produce. To achieve good air distribution, these fans should pull, never blow, the cooled air through the produce as fast as practical.

Features and Benefits: 
  • It decreases the time the produce remains at elevated temperatures, thereby reducing deterioration;
  • It results in shorter cooling times and thus more efficient use of the cooling facility;
  • It can cool produce effectively in a variety of unopened containers without wetting it or subjecting it to excessive handling;
  • It is often more energy efficient than room cooling when large volumes of produce must be cooled;
  • An available room-cooling facility with adequate cooling capacity can be converted to forced-air cooling with only a relatively small investment in fans

Design of Evaporator :

The theory of the evaporator is to mechanically expose more quantum of water mixed with compressed air in to the atmospheric air and to keep that water particles aloft long enough to evaporate them naturally. To achieve this performance we have designed Bipolar nozzles in which Air and water feed simultaneously to produce and send water droplets in to the air for long time to keep them aloft for long distance to evaporate them naturally.

For the same we recommend a pump with pressure of 50 mtrs Head and Air compressor with 6 kg/ pressure. As per general observation, about 60 to 70% of the water spray pump capacity would be evaporated in to the atmosphere on the driest day of the year. Water spray capacity of the pump, about 70% to 80% volume of the same would be maximum evaporated and thus it is estimated that about 70 to 80% of pure water would be evaporated from the sprayed mist.

Actual evaporation capacity will depend on percentage humidity, temperature condition, air wind velocity etc. on a respective day and thus above details are true for estimation only and may vary as per atmospheric condition. To reduce the cost of making Tower we can use you roof top to install the same.

Forced Circulation Evaporators

Description: 

Aman Water Tech offers a complete range of Forced Circulation Evaporators with options of crystallization and additional accessories like elutriation legs, hydrocyclones , post product centrifuge / spray dryer for crystal separation / drying.

Forced Circulation Evaporators are short tube evaporators and are ideally used when the boiling of feed liquid on the heating surfaces is to be avoided due to the salting and fouling characteristics of the liquid. Hence in these evaporators the flow velocity in the tubes is kept very high.

As the name implies, force is used to drive the liquid through the evaporator tubes thus producing high tube velocities. A high efficiency circulating pump, designed for large volume and sufficient head, is used to supply the force. Proper design results in controlled temperature rise, controlled temperature difference and tube velocities that give optimum heat transfer. This type is recommended for viscous, scaling and salting liquids. As the liquid is only heated in the steam chest with flashing taking place in the separator and no boiling taking place within the tubes, fouling on hot tube walls is reduced.

Features and Benefits: 
  • Suitable for widest variety of evaporator applications.
  • Ideal for crystallizing operation.
  • High heat transfer coefficients.
  • Positive circulation.
  • Freedom from salting, scaling and fouling.

  • Can use horizontal or vertical tubes.
  • Tubes are readily accessible for cleaning and inspection.
  • Suitable for single or multiple effects.

Multi Effect Evaporators

Description: 

Multi-Effect Evaporation is an important procedure adopted to economize the consumption of energy. The Multi Effect Evaporators are designed to economize the consumption of energy. These are designed in such a way that the steam from an outside source is condensed in the heating element of first effect. Further for second effect the boiling temperature of first effect is just too high that evaporated water can serve as the heating medium. The formed vapors than send to condenser, if it is the double effect evaporator. OR

An evaporator is essentially a heat exchanger in which a liquid is boiled to give a vapour, so that it is also, simultaneously, a low pressure steam generator. It may be possible to make use of this, to treat an evaporator as a low pressure boiler, and to make use of the steam thus produced for further heating in another following evaporator called another effect.

But in the multi effect evaporators, the feed is generally transferred from the one effect to another, which leads to ultimate product concentration which further reaches to one effect of evaporator

Features and Benefits: 
  • Efficiently uses heat from steam to evaporate water.
  • Uses distillation process.
  • Used for concentration of liquids in the form of solutions.

Applications :

  • Sugar beet factories
  • Pharmaceutical industries
