Chilean mine utilises new desalination plant
After an investment of $100 million (£63.7 million), Chile is now the proud owner of the Mantoverde desalination plant – the first of its kind in the country. The desalination plant works by sourcing seawater in its catchment tower 300m from the seashore. It then begins a process to filter and purify the water, removing impurities such as salt and excess residue so that the water can ...

Flood water protection in the city of Buenos Aires - Case study
The Arroyo Mendrano is the second largest channeled stream of water running through Buenos Aires. In case of heavy rainfalls it overflows its banks and causes considerable material damage. When the retention basin which had been especially built to collect large quantities of water during strong precipitation events also overflowed, the government decided to have an alarm-system installed to ...

Tackling rainwater shortages during dry seasons using a socio-technical operational strategy
The management of water resources during the dry season is a major challenge associated with rainwater harvesting (RWH) technology, but is necessary given the human suffering that follows from resulting conditions of water scarcity. In this study, the parameters for dry season assessment are defined in terms of ‘no water days’ (NWD) and rainwater usage ratio. A simple socio-technical ...

Water turbidity detector introduction
Water turbidity detector Turbidity detector is an instrument used to measure the turbidity of water samples. It determines the turbidity of a water sample by measuring the degree of scattering of light through it. Turbidity detector is widely used in water treatment, environmental protection, health supervision and other fields.The working principle of the turbidity detector is based on the ...

Review of toxicological effects caused by episodic stressor exposure
Water quality monitoring tools that rely on data from stress‐response tests with continuous exposure at constant concentrations are not always appropriately protective when stressor exposure in the field is episodic in nature. The present study identifies various approaches that have attempted to account for episodic stressor exposure, describes the development of a toxicological effects database ...

The Function of an Ultrasonic Flow Meter
Running a water management operation requires taking a wide range of measurements. In addition to measuring the flow in your system, many systems must measure the water level of their channel, and one of the best tools for accomplishing this goal is an ultrasonic flow meter. If you’re considering using an ultrasonic flow meter in your operation, it’s a good idea to learn how this ...

Stakeholder engagement in multi-objective optimization of water quality monitoring network, case study: Karkheh Dam reservoir
Reservoir water quality is important for water quality management downstream. A hierarchical approach is developed to present the monitoring locations within a format that satisfies the objectives of social stakeholders for making final decisions. First, a CE-QUAL-W2 model is applied to simulate water quality variables in the reservoir for a long time using a set of historic data. Second, ...

Identifying water quality monitoring stations in a water supply system
Despite good quality assurance and conformance to the standards at the treatment plants, water quality could vary considerably within the distribution network. As water flows through the pipe network, its quality undergoes various transformations due to many factors such as the properties of the finished water, pipe materials, water temperature, water age and low level of disinfectant ...

Water quality index as a tool for wetland restoration
Worldwide, wetlands are subjected to increasing anthropogenic pressures resulting in loss of their hydrological and ecological functions. Such impacts are more pronounced in the case of wetlands in urban areas which are exposed to land use changes and increased economic activities. In many Indian cities, natural water bodies such as lakes are heavily polluted due to runoff from farmlands in ...
