LJJW Aquasolutions is focused on technology to help wastewater treatment plants not just to meet with nitrogen and/or phosphorous limits in their NPDES permit, but to recover nutrients from high strength sidestream generated from anaerobic digestion process as slow release fertilizer. Adoption of ammonia recovery technologies for sidestream treatment is very limited in the wastewater industry. only about 20% of ammonia in sidestream is recovered by Struvite formation, with the remaining 80% still returned to main stream for further treatment. The firm has developed a new process in which ammonia reacts with a commercially available additive to form a short chain polymer (or oligomer). The recovered product is a composite of struvite and oligomer, with analyzed nitrogen and phosphorus values comparable to commercially available N-P fertilizer.
