Evaporators are critical components in modern Zero Liquid Discharge (ZLD) systems and industrial effluent treatment plants. They concentrate and reduce wastewater volumes by evaporating water using heat, allowing for water reuse and easy solid waste disposal. At Ocean Envirotech LLP, we design, manufacture, and supply energy-efficient evaporators tailored for various industrial applications.
An industrial evaporator is a thermal processing system that removes water from industrial effluents, brine, or high TDS wastewater by boiling it and condensing the vapor. The clean water (condensate) is recovered for reuse, and the residue is either crystallized or safely disposed of.
Single Effect Evaporator – Simple & economical for small-scale operations
Multiple Effect Evaporator (MEE) – Energy-efficient; ideal for medium to large industries
Forced Circulation Evaporator – For high viscosity liquids and scale-prone effluents
Mechanical Vapor Recompression (MVR) Evaporator – Low energy usage & high recovery
Falling Film & Rising Film Evaporators – For temperature-sensitive solutions
Evaporation is being considered as an alternative process in an increasing number of wastewater treatment applications. It can be effective for concentrating or removing salts, heavy metals and a variety of hazardous materials from solution. Also, it may be used to recover useful by-products from a solution, or to concentrate liquid wastes prior to additional treatment and final disposal. Most applications of the technology also produce a high quality, reusable distillate-a very important feature where water conservation is a priority.
During evaporation, a solution is concentrated when a portion of the solvent, usually water, is vaporized, leaving behind a saline liquor that contains virtually all of the dissolved solids, or solute, from the original feed.
The process may be carried out naturally in solar evaporation ponds, or through the use of commercially available evaporation equipment.
Solar evaporation ponds usually are limited by land availability and cost, potential odor problems, or meteorologic and climatological conditions, whereas mechanical evaporators are relatively compact, reliable and efficient. Evaporators are heat exchangers that transfer heat from the process fluid into the refrigerant causing a phase change, evaporation. In
