Design and optimisation of industrial Water Application Planning (WAP): modelling multi-contaminant processes with regeneration technologies
In the context of freshwater stress and scarcity, industries use and produce large volume of water with high toxicity. The challenge is to find creative ways to minimise freshwater use with emphasis on protecting the environment. One of such creative ways is Water application Planning (WAP), which …

Overhead sprinkler irrigation strategies to reduce water and nitrogen loss from container-grown plants
… was to determine the influence of intermittent water application via overhead irrigation on water and N leaching, substrate water distribution, and plant growth in a pine bark substrate. Intermittent irrigation was defined as the application of a plants' daily water allotment in multiple …

Laboratory Test Program of Rotary Plate Sprinklers
… the 1970's. These designs tend to produce small application areas resulting in high application rates that could exceed the infiltration capacity of the soil and result in runoff. In 1988, Nelson Manufacturing introduced their ROTATORTM and SPINNERTM series low pressure sprinkler heads that had …

Producer Preferences for Alternative Irrigation Practices in the Arkansas Delta
… practices in the state of Arkansas. As groundwater in the state becomes more limited, the use of scientific scheduling, flowmeters, and more efficient row crop water application systems will allow producers to better manage water resources. We find relatively large, positive relationships …

Sanitizer efficacy towards attached bacteria in a simulated milk pipeline system using pure and mixed cultures
… system, which consisted of a pre-rinse with warm water, application of the cleaning solution, post-rinse with warm water, and application of the sanitizing solution, allowed microorganisms to remain, when the bacteria were present as a pure culture, but resulted in the complete removal of bacteria …

Economic and environmental trade-offs of irrigation best management practices in the Lower Arkansas River Valley
… Implementing a series of regional land and water Best Management Practices (BMPs) is thought to reduce the negative impacts ("bads") of irrigated agriculture in the region and in some cases, increase the productivity of land and water ("goods"). A deeper understanding of impacts of proposed …

An experimental study of the environmental impacts of CCA-treated wood waste land application
… due to complexation reactions. With higher water application or where the adsorption capacity of the soil is exceeded, the metal(loid)s are transported through the soil column as leachate. Overall, there was a loss of metal(loid)s from the system that could be due to loss of water, …
