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.
