This chapter explores how water has been put to use to serve communities. Among the myriad uses that water has served, irrigation was certainly one of the earliest and most important, particularly to communities in arid regions. Indeed, the long-term viability of these communities depended on maintaining irrigation systems in the face of multiple ...

Water Production Reaction on Rh(110)
Journal of the American Chemical Society, 2005By means of scanning tunneling microscopy and density functional theory calculations, we studied the water formation reaction on the Rh(110) surface when exposing the (2 x 1)p2mg-O structure to molecular hydrogen, characterizing each of the structures that form on the surface during the reaction.

This chapter shows two not very widely known devices to obtain fresh eater from air. These devices could explain how ancient towns could resist to long sieges without any apparent source of fresh water. Moreover, these device are very simple to build and do not need any external source of energy, so they could be used even in the present days in ...

Productive Water Use in Rice Production: Opportunities and Limitations
Journal of Crop Production, 2000Summary It is crucial for food security to produce more rice with decreasing availability of water for rice production. This article seeks to answer the question “Does rice really require an abundance of water?” and discusses strategies and options to make rice production more water-efficient.

Water is the culture environment for fish or other aquatic organisms. It is the physical support, in which they carry out their life functions, such as feeding and excretion. Water properties can be divided into two main categories: physical characteristics, like density and temperature, and chemical characteristics, the concentration of solutes and ...

Water Footprint of crop productions: A review
Science of The Total Environment, 2016Water Footprint is an indicator recently developed with the goal of quantifying the virtual content of water in products and/or services. It can also be used to identify the worldwide virtual water trade. Water Footprint is composed of three parts (green, blue and grey waters) that make the assessment complete in accordance with the Water Footprint ...

Water disinfection and disinfection by products
Environmental Monitoring and AssessmentFor ecological safety and public health, it is essential to identify the causes of pollution in water sources and the effects of both natural and human activities. A class of secondary pollutants known as disinfection byproducts (DBPs) is produced when water is treated with disinfectant.

Optimised product and water recovery from batch-production rinsing waters
Waste Management, 2000Abstract Product concentrate can be recovered from rinsing waters [cleaning in place (CIP)] of surfactant and detergent batch production processes by using ultrafiltration and nanofiltration membranes. The problem in designing a separation process for the rinsing water is that the different compositions of the CIP-batches result in different ...
