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.

Pre Treatment

Advanced oxidation processes (AOPs) have recently received attraction for treatment of different wastewaters. AOPs have an ability to oxidize a high quantity of refractory organic matters, traceable organic, or to increase wastewater biodegradability as a pre-treatment prior to an ensuing biological treatment. In this chapter, the fundamental mechanisms of different AOPs such as ozonation, hydrogen peroxide, UV, persulfate, and Fenton oxidation are summarized. The combination of different oxidation processes such as O3/H2O2, O3/UV, O3/Fenton+, O3/persulfate are evaluated. Several persulfate activation techniques are also summarized.

Oxidation Processes

Advanced oxidation processes (AOPs) are widely used for the removal of recalcitrant organic constituents from industrial and municipal wastewater. The aim of this study was to review the use of titanium dioxide/UV light process, hydrogen peroxide/UV light process and Fenton’s reactions in wastewater treatment. The main reactions and the operating parameters (initial concentration of the target compounds, amount of oxidation agents and catalysts, nature of the wastewater etc) affecting these processes are reported, while several recent applications to wastewater treatment are presented. The advantages and drawbacks of these methods are highlighted, while some of the future challenges (decrease of operational cost, adoption of strategies for processes integration) are discussed.

Abstract Various processes that have been suggested for the oxidation of organic compounds in wastewater are summarized. The most widely applicable are based on generation of hydroxyl radicals via the photolysis of hydrogen peroxide, ozone and titanium dioxide. Other methods of generating hydroxyl radicals and other oxidants, as well as other methods of oxidation that have been suggested for organic wastewater treatment are also discussed.
