Schwing Bioset Nutrient Removal and Struvite Recovery

At plants utilizing anaerobic digestion, Struvite commonly forms and creates issues with pipes clogging and equipment being damaged as a result of scaling. Tanks also accumulate Struvite, which require periodic removal and additional expense to plant operations. Schwing Bioset’s nutrient removal system recovers Ortho-Phosphate and Ammonia Nitrogen from wastewater while offering benefits to the treatment plant. This controlled struvite formation significantly reduces phosphorus loads within the plant, and prevents unwanted scaling and accumulations while creating a valuable end product. The phosphorus forms a stable Struvite crystal that can be marketed and sold for beneficial reuse, thus keeping excess phosphorus out of the local waterways.
