Land Application Of Waste Water

The Volume As Well As Strength Of Waste Water Generated From Different Sectors Has Increased Due To Rapid Industrialisation, Urbanisation And Population Growth. Ensuring The Basic Standard And Quality Of The Receiving Waters Has Therefore Become Extremely Crucial. Land Treatment Of Waste Water Provides An Economically Viable And Technically Feasible Method Of Achieving This.This Book Presents A Systematic Exposition Of The Various Aspects Of Land Treatment To Fulfil The Needs Of Professional Environmental Engineers.The Different Techniques Of Applying Waste Water And Mechanism For Removal Of Bod, Nitrogen, Phosphorous, Micro-Organisms And Other Pollutants Have Been Discussed. The Design Principles For Slow Rate (Sr), Rapid Infiltration (Ri) And Overland Flow (Of) Systems Have Been Explained With Suitable Illustrations. The Possible Hazards Associated With Land Treatment And Effects Of Long Term Application Of Wastes On Soil Matrix Have Been Highlighted. Irrigability Index Has Been Developed To Assess The Quality Of Waste Water And Soil System Numerically, As Well As The Treatment Site By 5 X 5 Soil Sewage Interaction Matrix.Both Practising Environmental Engineers And Civil Engineering Students Would Find This Book To Be An Excellent Reference Source.

This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

Biosolids (appropriately treated sewage sludge) can make an important contribution to sustainable environmental management, through the return of organic material, trace elements, moisture and nutrients to our soils. The Guidelines for Environmental Management: Biosolids Land Application enables this beneficial use of biosolids, by providing a management framework that ensures any chemical and microbiological risks are appropriately managed.
