    How ROTEC Is Improving Desalination Technology Around the World

    High-recovery reverse osmosis (RO) is becoming a vital solution for both municipal and industrial water portfolios around the world. It is a reliable, drought-resilient water source that in many cases can be more affordable than importing new surface water. RO is also a critical component in the advanced treatment and reuse of municipal wastewater and the mitigation of seawater intrusion into groundwater aquifers. Historically, RO has been limited in application because of its low recovery rate—the ratio of treated water to feed water in the desalination process. In a system with a 75 percent recovery rate, for every 100 gallons of feed water that enter the system, 75 gallons of…

    Oceanus’s Hybrid Pumped-Storage Desalination Facility

    Desalination plants typically deal with two major problems: the desalination process requires a large amount of energy, and it results in a large amount of brine, which is difficult to get rid of and can be harmful to the natural environment. Oceanus Power and Water has discovered an innovative solution to both of these problems: combining a pump-storage facility, which stores power in the form of elevated water that can be used to drive turbines, with a desalination facility. Gravity power alone can dramatically reduce the energy demands of the desalination process. Moreover, the resulting brine can be reinjected into the stored seawater as it is released back into the…

    Luka Erceg of Drylet

    The process to treat and recycle biosolids can be time consuming and expensive for water treatment plants, but a new product called Aqua Assist is changing that. Added to wastewater treatment systems, Aqua Assist, developed by Drylet, uses a specially engineered microbe-delivery platform to break down and reduce biosolids, resulting in cost and equipment savings for treatment facilities. Luka Erceg is the president and chief executive officer of Drylet. After spending more than 20 years in the chemical, utility, and energy industries, Mr. Erceg joined Drylet and helped market Aqua Assist to municipal treatment plants nationwide. Mr. Erceg recently sat down with Municipal Water Leader’s lead writer, John Crotty, to…
