Wastewater a resource for phosphorus recoveryWastewater a resource for phosphorus recovery<div class="ExternalClass954C0BD5ACFC455BAB3E7CA41247150E"> <p>A trial at the Annacis Island Wastewater Treatment Plant last year has demonstrated it's possible to recover high quality phosphorus fertilizer from the region's wastewater.</p><p>The trial, funded by the Sustainability Innovation Fund and using equipment supplied by Ostara Nutrient Recovery Technologies, Inc., demonstrated that a full-scale phosphorus recovery system at the Annacis Island Wastewater Treatment plant could recover an additional 20 per cent of the phosphorus entering the plant. About 100 kilograms of high quality phosphorus fertilizer was recovered during the trial.</p><p>The findings will be used to inform Metro Vancouver's decisions regarding potential installation of phosphorus recovery equipment at existing and planned wastewater treatment plants.</p><p>Phosphorus is an essential resource to society, as well as a key ingredient in fertilizer, which is crucial to agricultural production. It is also a limited resource globally and in the future, wastewater treatment plants may be crucial sources of phosphorus.</p><p>Extra phosphorus that our bodies do not need passes through us, enters the sewerage system and is transported to Metro Vancouver's wastewater treatment plants. Some of the phosphorus, along with other nutrients that arrive at our wastewater treatment plants, is captured in the biosolids removed during treatment and is recycled through the production of Nutrifor and by land application of the biosolids. </p><p>At our Annacis Island Wastewater Treatment Plant, 40 per cent of the phosphorus that enters the plant is recycled in this way.  Additional phosphorus recovery can be achieved by advanced recovery technologies, such as the Ostara process. This form of recycled phosphorus can be sold as a fertilizer, replacing traditionally mined resources.</p></div>http://www.metrovancouver.org/metroupdate/PublishingImages/wastewater.jpg2017-05-25T07:00:00ZGP0|#3b8f3b80-a7ab-4371-9209-a63c0676026a;L0|#03b8f3b80-a7ab-4371-9209-a63c0676026a|Issue 32;GTSet|#d14ffe11-45dc-48fb-8684-ff109cf15a74<div class="ExternalClass051941BAB37B461599725854A0D18A51"><p>A trial at the Annacis Island Wastewater Treatment Plant last year has found it's possible to recover high quality phosphorus fertilizer from the region's wastewater.
