BOSTON, February 28, 2008 — Skyhaven Systems, LLC (RIL) has been awarded a contract from the Environmental Protection Agency to develop a chlorination process for treating surface groundwaters in small communities. Over 250 drinking water systems exist for small communities in Puerto Rico that serve 25-500 individuals. These water systems fall outside of the Puerto Rico Aquaduct and Sewer Authority and, thus, have no or insufficient water treatment systems. Water sources for these communities are from ground and surface water with flow rates up to 50,000 gallons per day for a community of 500 people. To improve upon this water treatment process, the EPA desires improved novel filtration and chlorination methods that can disinfect and filter these drinking water sources. To address this need, Skyhaven Systems, LLC will be developing an on-site hypochlorite generator that can continuously chlorinate surface groundwater. In this contract, RIL will apply its electrochemical reactor technology toward a compact and inexpensive system to produce hypochlorite on-site and on-demand for varying water flow rates and required disinfection levels. This will involve producing the reactor specifically for treating upwards of 50,000 gallons/day of surface water, developing the balance of plant and control system, and evaluating the system for disinfecting water. The improved design of RIL’s electrochemical reactor will help lower the system cost, one of the major drivers for deploying a water disinfection system into the marketplace.

The immediate application of this electrochemical reactor technology is toward an improved chlorination process for small communities in Puerto Rico. The modular design of the reactor technology will allow it to be scaled to medium and large water disinfection systems as well as scale it to produce higher levels of sodium hypochlorite for wastewater cleanup.
