Characterization and Treatment of Textile Wastewater covers fundamental knowledge of characterization of textile wastewater and adsorbents; naturally prepared adsorption and coagulation process for removal of COD, BOD and color. This book is intended for everyone actively working on the environment, especially for researchers in textile wastewater, as the problem of disposal of textile influent is worldwide. Potential technical environmental persons like engineers, project managers, consultants, and water analysts will find this book immediately useful for fine-tuning performance and reliability. This book will also be of interest to individuals who want effective knowledge of wastewater, adsorption and coagulation. - Includes definitions of pollutions, sources of wastewater in textile wastewater, various treatment methods, remedial measures and effect of waste - Examines research carried out and in progress worldwide by different researchers - Covers sampling procedures and determination of various parameters of textile wastewater

Chapter 2 Characterization of Textile Wastewater
Abstract
In this chapter, the collection, preservation, analysis method, and report of physicochemical and microbiological parameters of textile wastewater are mentioned. Principle, apparatus, interface, limitations, pretreatment, and procedure in short and detailed forms of 22 parameters are summarized. Water quality parameters are divided mainly into two parts: (i) titrimetric method [pollution-indicating parameters like chemical oxygen demand (COD) and biochemical oxygen demand (BOD), color, total hardness, magnesium hardness, and calcium hardness] and (ii) instrumentation parameters (pH, color, metals, etc.). The analysis report of 22 parameters for combined textile wastewater before treatment, collected from July 2009 to July 2010 bimonthly at GIDC Pandesara, Surat, Gujarat, is included. These parameters are compared with permissible limits of parameters for textile wastewater given by various firms including Central Pollution Control Board and US Environmental Protection Agency, which shows that COD and BOD values are 5 and 10 times, respectively, higher than limits. Characteristics of textile wastewater that were investigated and analyzed by different scientists are well fitted with one another. It shows that textile wastewater is highly polluted and treatment is necessary prior to discharge of it in environment.
