Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
The webpage of Midwest Rural Energy Council (MREC) provides a wide range of information on implementing small- and mid-scale biogas plantations in order to produce electricity.
Wastewater Characteristics, Treatment and Disposal is the first volume in the series Biological Wastewater Treatment, presenting an integrated view of water quality and wastewater treatment. This book covers the following topics: wastewater characteristics (flow and major constituents), impact of wastewater discharges to rivers and lakes, overview of wastewater treatment systems, complementary items in planning studies.

A WASHTech literature review of existing frameworks for technology assessment reveals that there is a gap for a WASH technology assessment tool and a WASH technology uptake tool. The authors of the review, which supports the development of WASHTech’s Technology Assessment Framework, (TAF), conclude that a computer tool based on an algorithm is not appropriate because it is too rigid. Choosing a manageable number of appropriate indicators is key for assessing new technologies.

This paper describes experiments using chitosan coagulant (a natural organic polyelectrolyte) on textile industry wastewater. The results obtained proved that chitosan successfully flocculates the anionic suspended particles and reduces the levels of Chemical Oxygen Demand (COD) and turbidity in textile industry wastewater.

This research assesses the agro based materials like Surjana seed (Moringa oleifera), Nirmali seed (Strychnos pototorum) and maize (Zeemays) as a coagulant aid in conjunction with alum to determine their efficacy in water treatment. Experiments have been conducted simulating a conventional water treatment train consisting of coagulation-flocculation-settling and granular media filtration. They found that filtrate quality has improved with the use of agro-based materials.

This research was carried out in Matlab, Bangladesh in collaboration with the International Centre for Diarrhoeal Disease Research, Bangladesh. They found significant filtering of zooplankton (i.e. copepods) and colonial phytoplankton from household water by nylon and sari filtration, as well as reduction of cholera cases in the studied villages.
