MAGNETIC PARTICLE TREATMENT FOR IRRIGATION WATER GREENER, BETTER, CHEAPER, FASTER

The wells of central California are the main water source for agriculture, but the brackish water contains high concentrations of total dissolved solids (TDS), and elements - like boron - in particular. Boron, while not a health hazard, can have unwanted consequences for tree health and yields. Farmers may want to reduce salinity of their wells, and typically use conventional reverse osmosis and ion exchange, but brine production, fouling of membranes, lack of adequate boron reduction, and high cost continue to hinder the use of treatment technology for well water meeting suitable quality for agricultural use.

ADS’s magnetic particle treatment adsorption system is the first-of-its-kind non-membrane technology to selectively remove contaminants with minimal energy consumption. The technology utilises synthetic small molecule receptors, coupled to magnetic particles, to bind and remove contaminants of concern from water.

The purification system is a reusable, specific, and relatively inexpensive tech- from saline source water derived from seawater wells. Kalaeloa Desalco has guaranteed to deliver 1.7 million gallons of potable water per day to BWS’s water system on a 24/7 basis. After commissioning, Kalaeloa Desalco will operate and maintain the plant for the following 20 years and potentially during two five-year optional extensions. The company expects revenue generated over the approximate 24-year base term of the contract to total about $204 million in current dollars. nique which dramatically reduces toxic brine and eliminates fouling of membranes, whilst reducing electricity demand, thereby reducing the cost and carbon footprint of water purification.

Advantageous systems (ADS) partnered with Isle’s Trial Reservoir to fund a successful pilot trial with Linneman Ranches in California, where the tested system provided greener, better, cheaper and faster results that will positively impact the water treatment and agricultural industry.
