CLEAN WATER SERVICES TO ADD SECOND OSTARA NUTRIENT RECOVERY FACILITY AT ROCK CREEK WASTEWATER PLANT

FOR IMMEDIATE RELEASE – HILLSBORO, OREGON and VANCOUVER, CANADA – March 1, 2011 – Clean Water Services and Ostara Nutrient Recovery Technologies Inc. have partnered to install an innovative nutrient recovery facility at Clean Water Services’ Rock Creek Advanced Wastewater Treatment Facility in Hillsboro, OR. This will be Ostara’s second installation of a commercial Pearl® Nutrient Recovery System at a Clean Water Services’ facility. Upon completion, the Rock Creek facility will be the largest Pearl facility in the world. Ostara’s first commercial Pearl Nutrient Recovery System began operating at Clean Water Services’ Durham Advanced Wastewater Treatment Plant in June 2009.

The Rock Creek facility will commence construction this summer as part of the plant’s expansion, and is expected to be fully operational by fall 2011. The facility will feature two Pearl 2000 fluidized bed reactors, significantly larger than the systems currently installed at the Durham facility in Tigard, and in Ostara’s other commercial facilities in York, PA and Suffolk, VA. Clean Water Services’ Rock Creek Advanced Wastewater Treatment Facility cleans 39 million gallons of wastewater a day from the municipalities of Hillsboro, Beaverton, Forest Grove, Cornelius, North Plains, Banks and Gaston as well as Aloha, Bethany, Cedar Mill, and Rock Creek.

“Our continued partnership with Ostara is a testament to the success of our first nutrient recovery system at the Durham facility,” says Bill Gaffi, General Manager of Clean Water Services. “This technology provides benefits to our ratepayers and the environment by extracting valuable nutrients – which would otherwise clog our pipes – to create an environmentally safe, revenue producing commercial fertilizer.”

A common challenge for wastewater treatment facilities such as Rock Creek is the over-accumulation of phosphorus in the equipment resulting in the formation of struvite scale, a concrete-like mineral deposit which congests processing equipment adding significantly to operating and maintenance costs and threatening plant reliability. Ostara’s Pearl process will help Clean Water Services overcome these challenges at Rock Creek with the recovery of up to 95 per cent of the phosphorus and 20 per cent of ammonia from the liquid wastewater stream at the Rock Creek facility, which will then be transformed – through a chemical reaction in Ostara’s proprietary fluidized bed reactors (Pearl 2000) – into an environmentally friendly, slow-release fertilizer marketed as Crystal Green®.

The Pearl 2000 reactors at Rock Creek will have the capacity to produce 1200 tons of Crystal Green fertilizer every year. Combined with the Durham facility, which has an annual capacity of 500 tons, Clean Water Services will become the largest producer of Crystal Green in the world.

With the Ostara process, phosphorus and other essential nutrients are recovered and transformed into Crystal Green which can be used locally by nurseries and other businesses within Washington County. Crystal Green provides a key environmental benefit – the protection of the Oregon waterways – as the fertilizer has limited runoff due to its unique slow release properties.

“Clean Water Services has always been a leader in adopting progressive solutions in wastewater management,” said Phillip Abrary, Ostara’s president and CEO. “We view Clean Water Services as a partner in reaching cost-effective and environmentally sound goals to recover nutrients for the highest beneficial re-use, and we are looking forward to our continued partnership with Clean Water Services on this state-of-the-art Pearl 2000 deployment at their Rock Creek facility.”

The production of Crystal Green is significantly less carbon-intensive compared to fertilizers produced from mined phosphorus. Further, once the recovered nutrients are transformed into Crystal Green, the fertilizer is dried using energy derived from the digestion of wastewater solids, further optimizing the economic and environmental efficiency of the project.

As the world’s first environmentally safe, slow-release fertilizer made from recovered nutrients, Crystal Green is ideally suited for the nursery, turf and specialty agriculture markets. It is sold through national and regional commercial fertilizer blenders across North America. A single application of Crystal Green on turf can replace multiple applications of phosphorus from other fertilizer blends, potentially reducing costs.

“Phosphorus, a key building block of life, is mined today in a limited number of areas but used globally as an essential agricultural input,” added Abrary. “We’re recovering phosphorus and other nutrients and transforming them into a useful, premium fertilizer while reducing the carbon footprint in its manufacture and preventing runoff in its use. By bringing the process full circle, we are truly creating value from waste.”

Gwinnett County is unveiling this week a system that will allow it to extract phosphorus from its wastewater to sell as fertilizer.

17 October 2015 – With the new technology, the county could profit from something that has cost money to dispose of in the past.

Phosphorus exists in human waste, and has to be removed before treated water can be sent back to lakes and rivers. Under the old system in Gwinnett, phosphorus built up in pipes and hardened when it was mixed with other chemicals. It had to be scraped out at a cost of about $100,000 a year and sent to landfills.

The county’s new nutrient recovery process removes phosphorus before it hits those pipes. Instead of throwing the phosphorus away, the county now sells it to the Canadian company Ostara, which in turn provides it to golf courses and farms.

Gwinnett spent $15.2 million to became the ninth facility in the world to have the technology produced by Ostara and is currently responsible for about 20 percent of the company’s production of fertilizer “pearls,” known as Crystal Green, Ostara CEO Phillip Abrary said.

Abrary said the process allows the county to “upcycle” what had been waste phosphorus in the past into a slow-release, environmentally friendly fertilizer.

The county expects to make about $220,000 a year through fertilizer sales. In addition to saving $100,000 annually in pipe cleaning costs, Gwinnett expects to save $600,000 a year in chemicals that it no longer needs to purchase and $250,000 a year in reduced waste disposal costs, said Ron Latimer, vice president of Hazen & Sawyer, a consulting firm.

“The problem was getting worse,” Latimer said. “The problems were more than creating a heartache for the plant.”

The project is expected to recoup its cost in 10 to 15 years.

Gwinnett has one of the strictest phosphorus limits in the country because of an agreement with the Lake Lanier Association, said Jeff Boss, deputy director of facilities for the Department of Water Resources. Letting too much phosphorus back into Lake Lanier, where the plant discharges its water, leads to algae blooms.

After phosphorus-heavy liquid is drained from solid waste at the treatment plant, it is mixed with an ammonium-filled liquid. When the two mix in a reactor, they create small, phosphorus-heavy seeds. Instead of coating pipes, the phosphorus pearls are now being sold back to Ostara as fertilizer.

Gwinnett is the first place in the state using the technology, but the city of Atlanta recently requested proposals for a similar project.

With the installation of the nutrient recovery system, the county is moving even further away from using the F. Wayne Hill Water Resources Centeras simply a facility for treating water, Boss said.

In addition to making fertilizer, the plant uses excess methane to power a generator at the site. It has recently purchased electric vehicles for travel around the area, which are powered by the generator. The department is also beginning a study to clean wastewater well enough that it can be used as drinking water without having to be released back to Lake Lanier and cleaned again.

“We want people in Gwinnett County to know how we’re spending their money. We want them to be proud,” Boss said. “If this was a pig, there’d be nothing left. We even use the squeal.”

The county will continue to look for ways the plant can make money off the waste it processes. In addition to helping to save money, Latimer said, the processes are better for the environment.

“There’s going to be a time when nothing leaves this plant as a debit,” Boss said. “We have a lot of irons in the fire.”
