Clearas Water Recovery – Advanced Biological Nutrient Recovery (ABNR™)

Biological-Based Wastewater Treatment Solutions

About the Company:

CLEARAS originated from a desire to change the paradigm in wastewater treatment and design. This came with the foresight that water was a severely undervalued commodity and that wastewater treatment could be transformed from linear, disposal-based systems to more circular, resource recovery-based solutions.

Due to increasing water pollution (algae blooms and other forms of contamination) caused by excess nutrients, regulations governing nitrogen and phosphorus discharge continue to tighten. Wastewater dischargers everywhere face the same challenges: minimizing environmental impact, while simultaneously investing in plant efficiency and improved performance. CLEARAS recognized the problem (algae blooms) and that it may also be the source of a more sustainable solution.

Founded in 2008, CLEARAS set out to be the leader in providing natural wastewater treatment solutions that transform waste into value – delivering unique cost recovery opportunities to customers.

In 2010, CLEARAS designed and built its first Advanced Biological Nutrient Recovery (ABNR™) system. This ABNR™ system delivered a simple, and chemical-free biological wastewater treatment solution to achieve ultra-low nutrient results.

Today, ABNR™ technology is at the forefront of a paradigm shift in wastewater treatment from removal to recovery. Through a unique application of biomimicry, ABNR™ leverages and enhances nature’s time tested patterns of nutrient recovery by transferring the problem – algae blooms – into the solution.

About the Solution:

CLEARAS delivers a sustainable, low-carbon wastewater treatment solution that recovers nutrients and transforms waste to value for customers and partners. Through the unique application of biomimicry, ABNR™ leverages nature’s time-tested patterns of nutrient recovery by taking the problem (algae blooms) and turning it into the solution.

As a bolt-on solution to existing infrastructure, ABNR™ manages and controls the relationship between mechanical and biological processes in a continuous flow environment to recover phosphorus, nitrogen and other contaminants prior to discharge. The problem is the solution.

ABNR™ is a sustainable and regenerative approach to nutrient treatment. It achieves best-in-class water quality, is modular and scalable, and produces a plant-based biomaterial co-product. That co-product is up-cycled into diversified and growing markets including plastics, foams, feeds, and soil enhancements. Customers benefit from a residual income stream created from the sale and up-cycling of this valuable plant-based biomaterial.

Solution Strengths, Weaknesses and Critical Indicators

NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.

General Support & Other:

  • Can be an integral part of many manure management systems
  • Most projects have at least some equipment that supports operations of the main technology
  • This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.

Newtrient Comments/Opinions:

Newtrient is currently working to collect additional information on the CLEARAS Water Recovery process and how it would best fit as part of a dairy operation.
