Multi Effect Evaporator (MEE) Plants Multi Effect Evaporator (MEE) Plants are advanced wastewater treatment systems used to concentrate high TDS and high COD industrial effluents by evaporating water through multiple stages (effects). At Sanskriti Enviro, we design and deliver efficient MEE solutions that help industries achieve maximum water recovery while minimizing waste and operational costs. Our MEE Plants are ideal for industries aiming for Zero Liquid Discharge (ZLD) and sustainable wastewater management. What is a Multi Effect Evaporator? A Multi Effect Evaporator is a thermal evaporation system where wastewater is heated and evaporated in multiple stages using the vapor generated from the previous effect as a heating medium. This process significantly reduces steam consumption and improves energy efficiency compared to single-effect evaporators. MEE systems are widely used to treat high-salinity, toxic, and non-biodegradable effluents that cannot be treated effectively by conventional ETP or STP systems. Our MEE Plant Solutions Sanskriti Enviro offers customized MEE systems designed to suit specific effluent characteristics and plant capacities, including: Forced Circulation & Falling Film MEE Systems Three to Seven Effect Evaporator Plants Integrated MEE with ATFD / Crystallizer Systems ZLD-based Evaporation Solutions Automated & PLC-Controlled MEE Plants Each system is engineered to deliver high evaporation rates with optimum energy utilization.

Feed Pre-Treatment Pre-treated effluent from ETP/RO is fed into the MEE system to prevent scaling and fouling. 2. Multiple Evaporation Effects Effluent passes through multiple effects where water is evaporated using low-pressure steam and recovered vapors. 3. Condensate Recovery The evaporated vapor is condensed to produce high-quality reusable water. 4. Concentrate / Reject Handling Concentrated effluent is further treated using ATFD or crystallizers for solid waste disposal.

Sewage Treatment Plants (STP) and Their Technologies A Sewage Treatment Plant (STP) is a treatment system designed to treat domestic wastewater generated from toilets, bathrooms, kitchens, residential townships, hotels, hospitals, commercial buildings and industries. The purpose is to remove suspended solids, organic pollutants, nutrients and pathogens so that treated water can be reused or discharged as per applicable pollution-control requirements. 1. Major STP technologies 1. ASP – Activated Sludge Process Conventional technology Uses biological treatment in an aeration tank followed by secondary clarification. Microorganisms consume dissolved and biodegradable organic matter. Main units: Screening, grit removal, equalization, aeration tank, secondary clarifier, sludge handling and disinfection. Suitable for: Residential townships, hotels, commercial buildings and large sewage flows. 2. MBBR – Moving Bed Biofilm Reactor Compact and robust Uses floating plastic carrier media on which microorganisms grow as a biofilm. Aeration and mixing keep the media moving. Main units: Screening, equalization, MBBR tank, media retention screens, secondary clarifier, filtration and disinfection. Suitable for: Apartments, hotels, hospitals, retrofit projects and space-constrained STPs. 3. MBR – Membrane Bioreactor High-quality treated water Combines biological treatment with membrane filtration. Membranes separate suspended solids and biomass from the treated water. Main units: Screening, equalization, biological reactor, membrane tank, permeate pumps, membrane cleaning system and disinfection where required. Suitable for: Premium residential projects, high-rise buildings, hotels and applications requiring high-quality reuse water. Key advantage: Small footprint and very low suspended solids in membrane permeate. 4. SBR – Sequencing Batch Reactor Treats sewage in batches inside a reactor, using timed cycles for filling, aeration, settling and decanting. Main units: Screening, equalization, SBR reactor, decanter, sludge handling and disinfection. Suitable for: Residential townships, institutions, hotels and developments with variable wastewater flows. Key advantage: Biological treatment and settling occur in the same reactor, reducing the need for a separate secondary clarifier. 5. Extended Aeration Process A variation of the activated sludge process that uses longer aeration time and generally lower organic loading. Suitable for: Small to medium residential complexes, schools, offices and institutions. Key advantage: Relatively simple operation and generally lower sludge production than conventional high-rate activated sludge systems, depending on operating conditions. 6. Anaerobic Treatment – UASB / ABR** Uses microorganisms that break down organic matter without oxygen. UASB means Upflow Anaerobic Sludge Blanket; ABR means Anaerobic Baffled Reactor. Suitable for: Certain large municipal sewage systems, warm-climate applications and projects where energy-efficient bulk organic removal is important. Important: Anaerobic treatment alone often does not achieve the final quality required for reuse or stringent discharge. Post-treatment is usually needed.
