Effluent Treatment Plant (ETP)

A stripping column is used to remove volatile components like ammonia or VOCs from wastewater. It works by passing air or steam through the wastewater, transferring the volatile substances into the gas phase. This method is commonly used as a pre-treatment step. It helps reduce load on downstream treatment processes.

RO is a pressure-driven membrane process that removes dissolved salts, heavy metals, and other impurities. It is used to treat high TDS wastewater, producing clean permeate and a concentrated reject stream. RO is essential for industries requiring water reuse. It helps meet discharge standards and water recovery goals.

ATFD is designed to handle high-viscosity waste and convert it into dry powder or flakes. It works by spreading the feed as a thin film on a heated surface under vacuum, with continuous agitation. This helps in effective drying and zero liquid discharge (ZLD). It is commonly used for final solid waste recovery.

Electrocoagulation uses electric current and metal electrodes to destabilize contaminants in wastewater. It removes heavy metals, emulsified oils, and suspended solids efficiently. The process forms flocs that can be easily separated by sedimentation or filtration. It is compact, chemical-free, and eco-friendly.

UF is a membrane filtration process that removes suspended solids, bacteria, and large organic molecules from water. It operates under low pressure and provides high-quality filtration before processes like RO. UF is widely used for pretreatment in ETPs. It ensures longer membrane life and improved efficiency in subsequent steps

MEE is used to concentrate high TDS effluents by evaporating water using multiple steam-heated stages. Each effect uses the vapor from the previous one, making it energy-efficient. It reduces wastewater volume significantly. The concentrated residue is sent to the dryer or further treated.

The oxidation process involves using chemicals like chlorine, ozone, or hydrogen peroxide to break down harmful pollutants. It effectively degrades organic contaminants and neutralizes toxic compounds. This process is used in both primary and tertiary treatment stages. It enhances overall water quality and safety.

UASB is a biological treatment process where anaerobic microbes break down organic matter in the absence of oxygen. Wastewater flows upward through a blanket of sludge, producing biogas as a by-product. It is energy-efficient and reduces sludge generation. UASB is ideal for treating high-organic-load industrial effluents.
