Evaporation Systems
Energy-efficient evaporation technology for wastewater volume reduction and zero liquid discharge applications
Overview
What is Evaporation Systems?
Evaporation systems provide an effective thermal treatment method for reducing wastewater volumes and achieving zero liquid discharge (ZLD) compliance. By applying heat to convert water into vapor, these systems concentrate dissolved solids and contaminants, producing clean condensate for reuse and minimizing waste requiring disposal.
Advanced evaporation technologies including Multi-Effect Evaporation (MEE), Mechanical Vapor Recompression (MVR), and Agitated Thin Film Evaporators (ATFE) offer energy-efficient solutions tailored to different industrial applications. These systems can handle high TDS wastewater, corrosive streams, and temperature-sensitive materials while minimizing operating costs through heat recovery and optimization.
Spans Envirotech designs and implements customized evaporation systems utilizing state-of-the-art equipment and process control. Our solutions integrate seamlessly with crystallizers, dryers, and other ZLD components to achieve complete water recovery, reduce environmental impact, and ensure regulatory compliance for industries worldwide.
Process
Evaporation Technology
Feed Preparation
Wastewater is pretreated to remove suspended solids and scale-forming compounds. Anti-scalants and pH adjustments optimize evaporator performance and minimize fouling.
Heat Application
Wastewater enters evaporation chambers where heat from steam, thermal oil, or compressed vapor raises the temperature, causing water to evaporate at atmospheric or reduced pressure.
Vapor-Liquid Separation
Water vapor rises and separates from concentrated brine. Mist eliminators and demisters prevent liquid droplet carryover ensuring high-quality distillate production.
Vapor Condensation
Separated vapor is condensed in heat exchangers, producing clean water suitable for process reuse. In MVR systems, vapor is compressed and recycled for energy recovery.
Concentrate Management
Concentrated brine (20-30% solids) is sent to crystallizers for further processing or solidification for safe disposal, achieving zero liquid discharge.
