Hydro International Receives $225,000 Deal to Supply Sixth Grit-Removal System in Puerto Rico

PORTLAND, Maine - Hydro International today announced the receipt of a $225,000 contract to supply a grit-removal system to serve the wastewater treatment plant in Isabela, Puerto Rico.

The Puerto Rico Aqueduct and Sewer Authority will use the Grit King® Separator unit to separate grit from water as the influent wastewater enters the treatment plant. The agency moved to upgrade its grit-removal system to meet the requirements of a consent decree issued by the United States Environmental Protection Agency’s Puerto Rico Aqueduct and Sewer Authority (PRASA). The installation of the system is scheduled to be complete by mid 2008.

The Grit King is an advanced hydrodynamic separator that removes grit by augmenting gravitational forces. It runs without the use of an external power source, and it does not contain any moving parts. It is one of a number of successful products in Hydro International’s wastewater portfolio, which includes the Grit-Cleanse™, a high energy vortex separator device, and the Reg-U-Flo® Vortex Valve, a device which optimizes flow control.

Hydro International has successfully implemented Grit King systems in a large number of locations throughout the world, including North America, the United Kingdom and Egypt. The company has five other Grit King installations in Puerto Rico, in San Lorenzo, Utuado, Santa Isabel, Lajas and Naranjito.

The City of Isabela is located along the coast in Puerto Rico’s northwest corner. The treatment plant serves 21,109 residents over approximately 20 square miles.

“Our grit-removal systems have enjoyed great success in Puerto Rico, providing our customers with a high level of service at an economical cost with minimal maintenance requirements,” said Stephen P. Hides, CEO, of Hydro International, based in Portland, Maine. “We are proud that the Puerto Rico Aqueduct and Sewer Authority has issued this latest vote of confidence, and we look forward to continued success in Isabela.”
