Wastewater Engineering: Treatment and Resource Recovery, 5/e is a thorough update of McGraw-Hill’s authoritative book on wastewater treatment. No environmental engineering professional or civil or environmental engineering major should be without a copy of this book – describing the rapidly evolving field of wastewater engineering technological and regulatory changes that have occurred over the last ten years in this discipline, including: a new view of a wastewater as a source of energy, nutrients and potable water; more stringent discharge requirements related to nitrogen and phosphorus; enhanced understanding of the fundamental microbiology and physiology of the microorganisms responsible for the removel of nitrogen and phosphorus and other constituents; an appreciation of the importance of the separate treatment of return flows with respect to meeting more stringent standards for nitrogen removal and opportunities for nutrient recovery; increased emphasis on the treatment of sludge and the management of biosolids; increased awareness of carbon footprints impacts and greenhouse gas emissions, and an emphasis on the development of energy neutral or energy positive wastewater plants through more efficient use of chemical and heat energy in wastewater.

• Wastewater as a Resource: Shifting the perspective to view wastewater as a valuable source of energy, nutrients, and even potable water.
• Stricter Discharge Requirements: Addressing the increasingly stringent regulations regarding nitrogen and phosphorus discharge.
• Microbiology and Physiology: Deepening the understanding of the fundamental microbiology and physiology of microorganisms vital for removing nitrogen, phosphorus, and other wastewater constituents.
• Return Flow Treatment: Recognizing the importance of treating return flows separately to meet nitrogen removal standards and facilitate nutrient recovery.
• Sludge Treatment and Biosolids Management: Emphasizing the effective treatment of sludge and the responsible management of biosolids.
• Carbon Footprint Awareness: Increasing awareness of carbon footprint impacts and greenhouse gas emissions associated with wastewater treatment.
• Energy-Neutral Plants: Focusing on developing energy-neutral or even energy-positive wastewater treatment plants by optimizing the use of chemical and heat energy within wastewater.

This revision contains a strong focus on advanced wastewater treatment technologies and stresses the reuse aspects of wastewater and biosolids.
