Abstract: Since rainwater is considered to be one of the safest sources of water, this study is focused on the rainwater quality parameters collected from the Savar area, Dhaka, Bangladesh. The main purpose of the study was to assess the rainwater quality variation in terms of drinking water quality standards given by the World Health Organization (WHO) to observe whether further treatment is needed or not for household applications. This location was selected due to the increased number of industries and textiles in the Savar area. For this investigation, four samples were collected in the months of April and May 2022 during rainfall. Several parameters were analyzed such as pH, electrical conductivity (EC), turbidity, salinity and total dissolved solid (TDS). The turbidity values varied from 0 to 2.21 NTU which suggested that the samples were optically clear enough. The pH, EC, salinity and TDS values, which are the chemical properties of the samples, ranged from 6.03 to 6.37, 21 to 62.2µS/cm, 0 to 0.1% and 10.51 to 27.8 ppm respectively. The results revealed that the quality of the rainwater samples found in this investigation was in the good range in terms of drinking water quality standards and it is safe for further applications.

Abstract: In the recent past, water contamination is an alarming topic for humans, the environment and other living beings. Water becomes wastewater after its use for different purposes in daily life or industries. As the population is growing rapidly, the amount of wastewater is increasing day by day for its high demand which has a large adverse effect on our environment and daily life. Industries are the major consumers of fresh water and so they produce a large amount of industrial effluents. Due to the large effluents containing toxic pollutants (e.g., dyes, heavy metals, surfactants, personal care products, pesticides, pharmaceuticals) from agricultural, municipal, and industrial resources, water becomes contaminated and its properties like the smell, color, COD, BOD, Turbidity, pH, TDS, etc. have been changed drastically. This change in water quality has a great effect on human health and the aquatic environment. To maintain the ecological environmental balance and to ensure fresh water for living beings, water has to be treated effectively. There are several techniques for the treatment of industrial wastewater such as adsorption, coagulation/Flocculation, chemical precipitation, advanced oxidation process, anaerobic system, stabilization pond, etc. The selection of treatment procedure varies from one type of industry to another as wastewater contains different pollutants. This paper focuses on the characteristics of industrial wastewater, its treatment steps, different treatment methods and sludge treatment used in industries for the treatment of effluents.
