Environmental Engineering 2 by BC Punmia PDF Download: A Comprehensive Guide for Students and Professionals

Environmental engineering is a branch of engineering that deals with the design, construction, operation and maintenance of systems and processes that protect human health and the environment from various types of pollution. Environmental engineering 2 by BC Punmia PDF download is a popular book that covers the topics of waste water engineering and air pollution in detail.

environmental engineering 2 by bc punmia pdf download

The book is divided into two parts: Part I deals with waste water engineering, which includes the collection and conveyance of sewage, wastewater flow rates, characteristics of sewage, sewage treatment methods, disposal of sewage effluent and sludge, rural sanitation and low cost treatment systems. Part II deals with air pollution, which includes the sources and effects of air pollution, meteorology and dispersion of air pollutants, sampling and analysis of air pollutants, control of gaseous pollutants, control of particulate pollutants, noise pollution and solid waste management.

The book is written in a simple and lucid language, with numerous examples, illustrations, tables and diagrams to aid the understanding of the concepts. The book also contains objective type questions, theoretical questions and numerical problems at the end of each chapter to test the knowledge of the readers. The book is suitable for undergraduate and postgraduate students of civil engineering, environmental engineering and related disciplines. It is also a useful reference for practicing engineers, consultants and researchers in the field of environmental engineering.

Environmental engineering 2 by BC Punmia PDF download is available online from various sources. However, it is advisable to purchase the original book from a reputed publisher or a reliable online platform to ensure the quality and authenticity of the content. The book is a valuable resource for anyone who wants to learn more about the principles and practices of environmental engineering.

In this article, we will review some of the main topics covered in the book Environmental Engineering 2 by BC Punmia PDF download. We will also provide some links to other resources that can help you learn more about these topics.

Waste Water Engineering

Waste water engineering is the branch of environmental engineering that deals with the collection, treatment and disposal of wastewater generated from domestic, industrial and agricultural sources. Wastewater contains various organic and inorganic pollutants that can pose a threat to human health and the environment if not properly treated and disposed. Waste water engineering aims to design and operate systems and processes that can remove or reduce these pollutants to acceptable levels before discharging the wastewater into natural water bodies or reusing it for beneficial purposes.

Some of the topics covered in the book Environmental Engineering 2 by BC Punmia PDF download related to waste water engineering are:

  • Systems of waste and sewage disposal: This topic covers the different methods of disposing human excreta and other wastes, such as conservancy system, water carriage system, low cost sanitation system, etc.

  • Collection and conveyance of sewage: This topic covers the design and construction of sewers, sewer appurtenances, pumping stations, etc. that are used to collect and transport sewage from its source to the treatment plant.

  • Wastewater flow rates: This topic covers the estimation of wastewater flow rates from various sources, such as domestic, industrial and storm water. It also covers the variations in flow rates due to diurnal, seasonal and other factors.

  • Characteristics of sewage: This topic covers the physical, chemical and biological properties of sewage, such as temperature, color, odor, solids, organic matter, nutrients, pathogens, etc. It also covers the methods of sampling and analysis of sewage.

  • Sewage treatment methods: This topic covers the various methods of treating sewage to remove or reduce its pollutants, such as preliminary treatment, primary treatment, secondary treatment, tertiary treatment, advanced treatment, etc. It also covers the design and operation of various treatment units, such as screens, grit chambers, sedimentation tanks, trickling filters, activated sludge process, anaerobic digestion, etc.

  • Disposal of sewage effluent and sludge: This topic covers the methods of disposing the treated sewage effluent and sludge generated from the treatment process, such as discharge into natural water bodies, land application, reuse for irrigation or industrial purposes, incineration, composting, etc. It also covers the standards and criteria for effluent and sludge disposal.

  • Rural sanitation and low cost treatment systems: This topic covers the issues and challenges of providing sanitation facilities in rural areas and developing countries. It also covers the design and implementation of low cost treatment systems that can provide adequate sanitation with minimal resources and maintenance requirements.

If you want to learn more about waste water engineering, you can refer to these online resources:

  • Water Supply and Sanitation Policy in Developing Countries Part 1: Understanding Complex Problems: This is a free online course offered by Coursera that introduces the key principles and concepts of water supply and sanitation policy in developing countries.

  • Environmental Engineering Applications of Fluid Mechanics: This is a free online course offered by MIT OpenCourseWare that covers the applications of fluid mechanics to environmental engineering problems such as pipe flow, open channel flow, groundwater flow, wastewater treatment, etc.

  • Wastewater Management: This is a website maintained by the US Environmental Protection Agency that provides information and guidance on various aspects of wastewater management such as regulations, permits, technologies, best practices, etc.

Air Pollution

Air pollution is the presence of harmful substances in the atmosphere that can cause adverse effects on human health and the environment. Air pollution can be caused by natural sources such as volcanic eruptions or forest fires or by anthropogenic sources such as combustion of fossil fuels or industrial activities. Air pollution can affect the quality of air at local or regional scales or even at global scales such as climate change or ozone depletion.
