Textile Wastewater Treatment

An experiment of advanced oxydation processes (AOPs) was applicated in textile wastewater treatment for color removal. The experiment was conducted in laboratory scale using ozon and hydrogen peroxide as oxidizing agents. The textile wastewater contains any organic and inorganic dyes that could not be effective treated by coagullation and and sedimentation as well as by conventional aerobic treatments. Result of the experiments concluded that the AOPs technologies could be applied effectively for removal of color. Addition of hydrogen peroxide with volume of 0.25 ml for 1 liter of wastewater exhibits the reaction. The reaction of AOPs for color removal was optimum at temperatur of 70oC. As higher as pH, the reaction become faster and the efficiency of color removal become higher.   Key words:  advanced oxidation processes, color removal, hydrogen peroxide, ozon,

Oxidation Processes

Textile manufacturing is a multi-stage operation process that produces significant amounts of highly toxic wastewater. Given the size of the global textile market and its environmental impact, the development of effective, economical, and easy-to handle alternative treatment technologies for textile wastewater is of significant interest. Based on the analysis of peer-reviewed publications over the last two decades, this paper provides a comprehensive review of advanced oxidation processes (AOPs) on textile wastewater treatment, including their performances, mechanisms, advantages, disadvantages, influencing factors, and electrical energy per order (EEO) requirements. Fenton-based AOPs show the lowest median EEO value of 0.98 kWh m−3 order−1, followed by photochemical (3.20 kWh m−3 order−1), ozonation (3.34 kWh m−3 order−1), electrochemical (29.5 kWh m−3 order−1), photocatalysis (91 kWh m−3 order−1), and ultrasound (971.45 kWh m−3 order−1). The Fenton process can treat textile effluent at the lowest possible cost due to the minimal energy input and low reagent cost, while Ultrasound-based AOPs show the lowest electrical efficiency due to the high energy consumption. Further, to explore the applicability of these methods, available results from a full-scale implementation of the enhanced Fenton technology at a textile mill wastewater treatment plant (WWTP) are discussed. The WWTP operates at an estimated cost of CNY ¥1.62 m−3 (USD $0.23 m−3) with effluent meeting the China Grade I-A pollutant discharge standard for municipal WWTPs, indicating that the enhanced Fenton technology is efficient and cost-effective in industrial treatment for textile effluent.

Textile Wastewater Treatment

The use of conventional textile wastewater treatment processes becomes drastically challenged to environmental engineers with increasing more and more restrictive effluent quality by water authorities. Conventional treatment such as biological treatment discharges will no longer be tolerated as 53% of 87 colours are identified as non-biodegradable. Advanced oxidation processes hold great promise to provide alternative for better treatment and protection of environment, thus are reviewed in this paper. An overview of basis and treatment efficiency for different AOPs are considered and presented according to their specific features.
