Dried up reservoirs, cracked dirt and empty swimming pools are just a few of the visual reminders of the ongoing California drought. But what most people don’t see is the water providers, like Mark Sprague at the City of Fountain Valley, working tirelessly to keep the water running.
When high levels of arsenic were found in the drinking water in the community of Alto Lampa outside of Santiago de Chile, municipal water provider Aguas Adinas faced a predicament. AdEdge Water Technologies was contacted to design a treatment approach. This case study describes how iron oxide adsorption helped Alto Lampa reduce arsenic levels in treated water to non-detectable concentrations.
The Little America West Hotel complex located near the town of Granger, Wyoming, used an outdated surface water treatment plant that provided poor quality water during storm events.
The client's reverse osmosis system utilized coagulants, antiscalants and cleaners to produce high quality water. With the current chemicals, the reverse osmosis system was cleaned every 90 days due to scaling or deposits.
“You can’t manage what you don’t monitor”, an adage first attributed to Lord Kelvin applies to practically everything, including water distribution systems.
Kibbutz Reim had to convert salty groundwater into a high quality irrigation resource in this desert-like region. High recovery was essential to this customer, both because of the limited amount of groundwater available and the challenge of brine disposal from their inland location.
The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.
Iron is one of the earth's most plentiful resources, making up at least five percent of the earth's crust. In well water iron is usually found as ferrous iron, which is in a dissolved state and may appear clear when first drawn from the tap.
