Impressive OriginClear EWS technology - from the article: "EWS is energy-efficient and can achieve up to a 99.9 percent removal of dispersed oil and a 99.5 percent removal of suspended solids and organics, as well as specific contaminants such as ammonia, phosphorus and hydrogen sulfide, the company says.

“Bundled together with a reverse osmosis system, we can reach an economic cost that is sustainable in the long-term,” Kindler said. “This is what we are trying to show in Bakersfield: reverse osmosis and EWS will make the whole solution sustainable in economic and technical terms.

“Reverse osmosis systems are doing a great job of purifying water but they have a cost: energy to provide the pressure that is needed for these systems to operate and the other cost is maintenance. The dirtier the water, the more often the membrane needs to be changed. What we propose is a solution where, because we have taken out most of the contaminants, reverse osmosis systems will have a much longer life and much lower operation costs.”

Water contracts for farmers in California can cost upwards of $2,000 per acre foot, Kindler says. For comparison, EWS, when used with reverse osmosis, costs between $1,000 and $1,300 per acre foot to treat water.

“Any technology to treat water has a cost,” Kindler said. “We know our solution is one of the most economically competitive on the market, but still it has a cost. And at some point there needs to be a realization that water isn’t just something that falls from the sky. It has to be paid for.”
