Our patented system can be used for a wide variety of municipal and industrial applications.
Ammonia recovery and BOD treatment for small towns and municipalities
Total nitrogen and phosphorus recovery for medium-to-large cities
Nutrient recovery and surcharge prevention for industrial applications
Secondary Treatment with Nutrient Removal
The RAB™ system is well-suited to be located on the front end of an existing wastewater lagoon when additional Biochemical Oxygen Demand (BOD), Ammonia (NH3), Total Nitrogen (TN), and/or Total Phosphorus (TP) Treatment are needed. When the BOD concentration is higher, the RAB™ system will grow a mixed culture of both bacteria and algae, which can simultaneously remove BOD, NH3, TN, and TP.
Sidestreams at wastewater treatment plants, such as anaerobic digestion effluent and sludge thickening supernatant typically are recirculated back to the front end of the plant. These waste streams are typically very nutrient-dense with relatively low flows (compared to the rest of the plant). Sidestreams have nutrient concentrations ideal for algae growth and our RAB™ system.
The RAB™ is unique in this application as it is the only technology that can simultaneously remove both nitrogen and phosphorus from the sidestream.
Fixed-Film Tertiary Treatment
The RAB™ system can be a simple retrofit on the back end of an existing wastewater treatment plant for polishing TN and TP to meet stricter effluent discharge limits. This allows plants to keep their existing infrastructure, preventing costly upgrades to the entire plant. Specifically, the RAB™ is an excellent addition for fixed-film plants that require additional treatment to meet total nitrogen and/or total phosphorus permits.
Many industries in the food and beverage space are facing higher surcharge rates. This pushes a decision to either invest in infrastructure to bring pollutant levels down or continue to pay high surcharge rates. The RAB™ system is well-suited to be a pre-treatment solution for these industries. The RAB™ system provides a low-energy, sustainable technology that can cost-effectively bring surcharge rates down, and reduce a company’s carbon footprint.
