Simultaneous Nitrification and Denitrification in Biofilms of an Engineered Integrated Fixed-Film Activated Sludge (IFAS) System

The Florida coastal community of Green Cove Springs is experiencing sudden growth pressures from the expanding suburbs of the city of Jacksonsville. An engineering firm (Camp Dresser & McKee) was retained to plan a treatment upgrade of the Harbor Road Wastewater Treatment Plant. The objective was to meet a consent order from the Florida Department of Environmental Protection to meet an unionised ammonia limit of 0.02 mg/L for river discharge.

Safe Water Delivered Safely

This document will first review the types of water pipelines used throughout the U.S. and Canada, the types of structural problems some of these pipes experience and the costs that are incurred due to these structural problems. Because pipeline structural problems can lead to contamination, this document will also discuss the increased threat of waterborne diseases. Finally, because chlorine chemistry plays a major role in safely delivering water to homes, businesses and schools - through both disinfection and piping material - this paper will show how pipelines made from chlorine-based vinyl plastic are part of the solution to these water-transport challenges.

The Food and Agriculture Organisation of the United Nations (FAO) compiled a very comprehensive publication on water-lifting devices. Its purpose is to provide a basis for comparing and choosing between all present options for lifting irrigation water on small and medium sized land-holdings.

Targeting Appropriate Interventions to Minimize Deterioration of Drinking-water Quality in Developing Countries

In developing countries, it has been observed that drinking water frequently becomes recontaminated following its collection and during storage in the home. This paper proposes a semi-quantified ‘disease risk index’ (DRI) designed to identify communities or households that are ‘most at risk’ from consuming recontaminated drinking water. A brief review of appropriate physical and educational intervention measures is presented, and their effective use is discussed. It is concluded that incorporating a simple appraisal tool, such as the proposed DRI, into a community water-supply programme would be useful in shaping the overall strategy requiring only a minimum of organisational learning.

Guidelines for Drinking-water Quality. Second Edition, Volume 3

This volume of Guidelines for drinking-water quality describes the methods employed in the surveillance of drinking-water quality in the light of the special problems of small-community supplies, particularly those of developing countries, and outlines the strategies necessary to ensure that surveillance is effective. It is also concerned with the linkage between surveillance and remedial action and with the form that remedial action should take.
