Unique Dual Purpose Algal Turf Scrubber® to Be Built In Indian River County, Florida

April 24, 2013

Vero Beach, Florida (April 25, 2013) –

Indian River County Florida requested construction bids for a groundbreaking Algal Turf Scrub- ber® (ATS™) expected to be operational in the first quarter of 2014.

Faced with the necessity to stop discharging brine from the South County Reverse Osmosis Water Treatment Plant, the County asked HydroMentia if an Algal Turf Scrubber® could pro- vide a less expensive, environmentally friendly alternative to deep well injection; a process in which waste fluids are injected below ground for disposal.

“The ATS™ technology is highly adaptable to a variety of needs and situations,” said Mark Zivojnovich, HydroMentia Vice President of Project Development. “Working with Indian River County we found a way to solve the brine problem and clean water from a nearby canal at the same time, saving money and alleviating environmental concerns regarding deep well injec- tion.”

The facility will blend water from the Indian River Farms Water Control District’s canal system, mix it with brine disposal water from the reverse osmosis plant, and treat it through an Algal Turf Scrubber®.

HydroMentia tested the blended flow through an ATS™ for six months, during which the sys- tem had to pass rigorous tests required by the Florida Department of Environmental Protection. “FDEP needed assurance that the system would meet specifications. Once they saw that we had a sustainable solution they green lighted the project and we worked with the County to de- sign and permit the system,” Zivojnovich said.

Construction bids for the 10 million gallon per day PC-South Algal Turf Scrubber® project are due on May 29, 2013 and construction should commence later this summer.
