The term “evaporator” refers to process equipment used to extract liquid by vaporization. A single liquid, a liquid mixture, solutions or slurries, or any combination of these may be used as the feed material. To create vaporization, heat is delivered through some type of heat transfer surface. Evaporation systems are intended to concentrate feedstock into a heavy solution or slurry to reduce its volume for subsequent processing, use, or disposal.
Single effect evaporators and multiple effect evaporators are the two most common types of evaporators in the market. The benefits of multiple effect evaporators include their suitability for large-scale and continuous operation. When compared to a single effect, it is extremely cost-effective. Multiple effects are employed to reduce the amount of energy required to evaporate unwanted water content.
What is a multiple-effect evaporator/ MEE Evaporator?
A multiple-effect evaporator is a device that efficiently uses steam heat to evaporate water. Water is boiled in a series of containers, each at a lower pressure than the last, in a multiple-effect evaporator.
It is made up of several stages or “effects.” The feed water is heated by steam in tubes at each stage, commonly by spraying saline water on them. Some of the water evaporates, and the resulting steam flows into the tubes of the following stage (effect), heating and evaporating even more water.
MEE Evaporators are commonly used for product concentration and are currently being utilized to collect water from wastewater that may be reused for industrial processes, lowering the industry’s overall freshwater consumption and leading to zero liquid discharge and sustainable development.

What is Mechanical Vapor Recompression (MVR) Evaporator?
Mechanical Vapor Recompression (MVR) is a proven energy-saving evaporative concentration method that decreases evaporation energy usage by 90% or more. MVR Evaporator employs condensate energy to produce pure liquid distillate and concentrated product/waste.
Why MVR evaporator?
Many industrial applications use vapor recompression, including those in the dairy, saline, and distillery sectors. Mechanical vapor recompression, in particular, is frequently used in industrial evaporators for solids concentration in distillation facilities. The goal is to transfer waste heat from a wasted vapor stream by increasing its pressure and reusing it to collect its usable energy.
To do this, the vapor produced by evaporator steam is compressed, causing its temperature and pressure to rise. As the pressure rises, so does the saturation temperature. This temperature rise results in a temperature differential between the exhaust vapor and the working fluid. The temperature difference allows heat to be transferred between the two fluid streams through a heat exchanger.
