Introduction to Industrial Wastewater Treatment
Industrial wastewater treatment is a critical process utilized to treat wastewater generated as a byproduct of industrial or commercial activities. It aims to remove pollutants and contaminants to produce a safe discharge or to enable water reuse. Key parameters such as Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solids (TSS) are monitored to ensure compliance with environmental standards.
Stages of an Industrial Wastewater Treatment System
Preliminary Treatment
The preliminary treatment involves screening and grit removal. This stage removes large solids and debris to prevent damage to subsequent treatment processes. Typically, bar screens with openings of 1-3 inches and grit chambers designed for a minimum flow velocity of 0.3 m/s are used.
Primary Treatment
This stage involves sedimentation tanks that allow heavier particles to settle. A typical design flow rate is 500 cubic meters per day with a retention time of 2-4 hours. Removal efficiencies of up to 60% for TSS and 30% for BOD are achievable.
Secondary Treatment
The secondary treatment utilizes biological processes to degrade organic matter. Activated sludge systems, with aeration tanks, ensure an oxygen transfer rate of 1.2-2.0 kg O2/kg BOD5. Contact times range from 6 to 8 hours, achieving up to 85% COD reduction.
Tertiary Treatment
This stage involves advanced treatment processes like filtration, nutrient removal, and disinfection. Membrane filtration systems operate at transmembrane pressures of 0.1-0.4 MPa, with removal efficiencies for pathogens reaching 99.99% using UV disinfection.
Sludge Treatment
Sludge generated from the treatment process is stabilized, typically through anaerobic digestion. This process reduces sludge volume by up to 50% and produces biogas with a methane content of 60-70%.
