5. Chapter 4. The Negative Impacts of Industrial Water Pollution on Human Health and Benefits of Zero Liquid Discharge System

   Asma Hasan, Baby Tabassum, Mohammad Hashim, Nagma Khan

   Abstract

   Rising populations and consumer demand have led to a rapid expansion of industrialization. As a result, the development of industrial setups has led to an increase in industrial waste generation. Untreated industrial wastewater is a major hazard to the environment because it contains harmful microbes, including viruses, fungi, bacteria, protozoa, and algae. Industries produce wastewater of different qualities. Some of the wastewater contains biodegradable components such as paper, wool, leather, textiles, etc., while other wastewater contains non-biodegradable waste such as heavy metals, radioactive elements, pesticides, and plastic. These pollutants can enter water sources through drainage systems, indiscriminate untreated effluent flow in water, disturb ecosystems, and threaten flora and fauna’s health as they move through the food chain. Industrial wastewater contains toxic, reactive, carcinogenic, or combustible substances that can cause acute toxicity, disturbed immune system function, and infertility. Therefore, it is essential to eliminate its toxicity through appropriate eco-friendly treatments in order to recycle water. Zero liquid discharge (ZLD) is a sustainable method of wastewater management that purifies liquid waste discharge. It is an ideal solution for industries that have to comply with stringent environmental regulations. The primary goal of ZLD systems is to collect and recycle waste water resources in order to decrease pollutants, leaving behind zero liquid waste. The present study highlights the benefits and uses of several ZLD technologies for sustainable water management, including thermal methods, reverse osmosis, membrane distillation, and soil biotechnology.

8. Chapter 7. Microbial Community Response to Waste Water Discharge in Water Bodies

   Devyani Ablankar, Udaykumar Reddy, Pranali Shete, Ashish Jain

   Abstract

   Earth has limited resources that humans may exploit, even if it is mostly covered by water. Furthermore, most of these constrained resources act as routes for the discharge of household and industrial waste. Water bodies that receive effluents exhibit significant changes in their biological life forms as well as their chemical and physical attributes. It is believed that anthropogenic activities, which contribute to population growth, are the main causes of the significant rise in effluents that ultimately cause changes in the dynamics of water bodies. It goes without saying that despite significant advancements in waste water treatment techniques, effluents still include a variety of organic and inorganic, hazardous and non-toxic substances, as well as microbial bioburden. Microbial populations can undergo both qualitative and quantitative changes as a result of effluent discharge and the resulting physical and chemical disturbances. Furthermore, the microbial populations in the receiving water bodies exhibit even greater variability as the effluent fluctuates in quantity and quality. Alterations in the composition of microbial communities can cause hazard to the environment because they can lead to the emergence of more drug- and pollution-resistant species. Knowing how the microbial population reacts to exposed effluents becomes crucial in light of these considerations. While uncultivable bacteria continue to be a worry for these objectives, approaches such as metagenomics and genome sequencing might be investigated. Designing techniques that address both the maintenance of native microbial populations in water bodies and wastewater control is crucial. As a result, the present chapter summarizes how various effluents alter microbial populations and how such changes may affect the ecosystem.

12. Chapter 11. Protection of Water Supplies from Contamination of Industrial Chemical Wastewater Disposal of Yavatmal District (MS) India—Case Study

    Priyanka M. Ramteke

    Abstract

    Jamwadi village in Yavatmal, Maharashtra, was a famous tourist attraction a decade ago due to its beautiful lake. Now, there is no lake to speak of, thanks to the Raymond factory in Yavatmal, which flows untreated into the lake, located 15 km away. This has severely affected the environment, health, and community life of Jamwadi village and six others in the area, namely Lohara, Yechuri, Tiwsa, Bhoyar, Varaz, and Chani. The paper is based on the results of the physicochemical characteristics of water in the village of Lohara, Jamwadi pond, and chemical analysis of water samples, both surface and groundwater, of Bhoyar village. Water quality is an essential criterion for evaluating the suitability of water for irrigation and drinking. An investigation was carried out to monitor the water. That water gets contaminated by industrial waste, domestic waste insecticide, etc., which is harmful for domestic use. This study aimed to estimate the current status of the physicochemical characteristics of Lower Jamwadi Reservoir in Yavatmal District, Maharashtra. Monthly changes in physicochemical parameters such as water temperature, pH, Colour, Acidity, Alkalinity, total dissolved solids, total solids, total hardness, chlorides, dissolved oxygen, and Chemical oxygen demand were analyzed in September 2014. The results indicated that the physicochemical parameters of the water were within the permissible limits and could be used for domestic, irrigation, and pisciculture.
