Multi effect Evaporator
Multi-Effect Evaporators (MEEs) are a highly efficient solution for wastewater treatment and resource recovery, designed to concentrate and reduce liquid waste while recovering clean water for reuse. At RTW UK, we integrate MEEs into our treatment systems to help industries achieve sustainable water management, meet Zero Liquid Discharge (ZLD) goals, and recover valuable by-products.
How Multi-Effect Evaporators Work
The MEE system operates by using a series of evaporators (effects) where wastewater is heated to produce vapor, which is then condensed into purified water. The heat energy from one stage is reused in the next, maximizing thermal efficiency and reducing operational costs.
Process Steps
Preheating
The wastewater is preheated to increase energy efficiency.
Evaporation
Heat is applied to the first effect, causing the water to evaporate and separate from dissolved solids and impurities.
Energy Recycling
The vapor generated in one effect is used as a heating source for the next effect, significantly reducing energy consumption.
Concentration
The residual wastewater becomes progressively more concentrated through successive effects, resulting in a solid or semi-solid residue.
Condensation
The vapor is condensed and collected as distilled water, ready for reuse or discharge according to environmental standards.
Key Features and Benefits of MEEs
Energy Efficiency
By reusing heat energy across multiple stages, MEEs consume significantly less energy compared to single-effect systems.
High Recovery Rates
Efficiently recovers water for reuse, reducing fresh water demand.
Versatile Applications
Suitable for treating wastewater with high Total Dissolved Solids (TDS) and for recovering valuable by-products like salts or chemicals.
Scalability
MEEs can be customized to handle varying wastewater volumes and concentrations, making them ideal for industries of all sizes.
Environmental Compliance
Helps industries meet strict environmental regulations by minimizing liquid waste discharge.
