WEST BOUNTIFUL, UT – Today the South Davis Sewer District (SDSD) announces the selection and implementation of CLEARAS Water Recovery’s Advanced Biological Nutrient Recovery (ABNR™) technology at its 4,000,000 gallon per day South Plant. ABNR is a key component of a $24 million plant upgrade to sustainably meet current and future nutrient discharge regulations. The ABNR platform, which is highly modular and scalable, leverages the relationship between biological (algae) and mechanical processes to achieve best-in-class nutrient removal. The ABNR project, which broke ground this month (May 2017), will bolt-on to existing South Plant wastewater infrastructure and is part of a larger upgrade of the South Davis treatment facility which also includes the construction of a food waste to energy process, which will produce 2,500 decatherms of renewable natural gas.
“ABNR has the potential to change the way we think about wastewater treatment and we are excited to have partnered with CLEARAS to advance the next generation of wastewater treatment and resource recovery.”
These projects represent the District’s focus on creating value for their rate-paying customers using sustainable, environmentally friendly technology. The ABNR project is estimated to take 14 months to complete and will be featured in October 2017 at the Algae Biomass Organization (ABO) Summit being hosted in Salt Lake City, UT.
“The SDSD ABNR facility demonstrates how innovative technology can be implemented to recover resources, provide significant environmental benefits to the region, produce reuse quality water and generate co-product income to offset costs,” said Dal Wayment, General Manager of SDSD. He continued, “ABNR has the potential to change the way we think about wastewater treatment and we are excited to have partnered with CLEARAS to advance the next generation of wastewater treatment and resource recovery.”
ABNR addresses one of the U.S. Environmental Protection Agency’s and the State of Utah Division of Water Quality’s highest priority issues; nutrient removal and recovery. Phosphorus and nitrogen are a natural part of the Wasatch Front aquatic ecosystem. However, when excess amounts enter the environment through wastewater discharge, surface run off and other sources, the receiving waters can be stressed in various ways. This in turn can result in environmental, economic and human health concerns. ABNR offers a chemical free, economically and environmentally friendly method of nutrient recovery resulting in high water quality for reuse while recycling carbon dioxide.
“We are pleased to have found an innovative and forward-thinking partner in South Davis. Their board and management have a strong vision and plan which aligns perfectly with our technology and company culture. This is an important commercial milestone for our business, the future of wastewater treatment and technologies which advance the circular economy, said Jordan Lind, CEO of CLEARAS.”
The project includes collaboration between CLEARAS Water Recovery (technology inventor and supplier), South Davis Sewer District (customer), AQUA Engineering (consulting engineer) and Alder Construction (contractor).
About CLEARAS Water Recovery
CLEARAS Water Recovery was founded in 2008 to advance the concept of waste recovery to value. Our patented ABNR wastewater solution is an advanced, non-chemical treatment that recovers phosphorus and nitrogen while reducing other harmful contaminants.
As a modular and bolt-on system, this technology scales to any available footprint and integrates seamlessly into existing wastewater treatment infrastructure to prevent system downtime and flow disruption, while maintaining the flexibility to meet a variety of effluent discharge requirements. The ABNR system achieves best in class tertiary water quality, recovering both phosphorus and nitrogen to near non-detect levels.
About South Davis Sewer District
In 1959, the South Davis Sewer District was organized by Davis County as an independent special district to provide wastewater services to south Davis County; consisting of Bountiful, Centerville, North Salt Lake, West Bountiful, Woods Cross, and the unincorporated areas south of Lund Lane. A seven-member Board of Trustees governs the District.
The District currently serves a total population of approximately 95,000 with two treatment plants: The North Plant is located at 1800 West 1200 North in West Bountiful, and the South Plant located at 1380 West Center Street in North Salt Lake. The North Plant can treat up to 12 million gallons per day (MGD) of wastewater and the South Plant can treat up to 4 million gallons per day. In addition to the treatment plants, the District owns and operates the collection system made up of 370 miles of sewer lines, 8,565 manholes and 10 lift stations.
