The solution? Recover phosphorus, especially that present in wastewater. <br \/>In most plants, phosphorus is removed in the sewage sludge through physico-chemical dephosphatation (precipitation of phosphorus using a chemical reagent, typically based on iron or aluminum) or biological methods (conditioning bacteria to accumulate phosphorus). The Extraphore\u00ae process, developed and patented by Saur-Stereau, aims to maximize biological dephosphatation to reduce the use of reagents and, consequently, costs. By instrumenting biological dephosphatation, it is possible to control the conditions needed to promote bacteria that accumulate phosphorus, especially in the anaerobic zone at the entrance of the biological basin.<\/p>\n<p>Phosphorus recovery potentially applies to all wastewater treatment plants with biological phosphorus removal, regardless of their size.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-3dfd0bb elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"3dfd0bb\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-0e51504\" data-id=\"0e51504\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-bf225ad elementor-widget elementor-widget-heading\" data-id=\"bf225ad\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">\"Phosphorus recovery potentially applies to all treatment facilities\nwith biological phosphorus removal, regardless of their size.\"<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f33ea72 elementor-widget elementor-widget-spacer\" data-id=\"f33ea72\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-7513556 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"7513556\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-b3636a4\" data-id=\"b3636a4\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-086669e elementor-widget elementor-widget-text-editor\" data-id=\"086669e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Phosphorus recycling, and thus resource preservation, represents a major challenge. <span style=\"font-style: inherit; font-weight: inherit; background-color: var(--ast-global-color-5); color: var(--ast-global-color-3);\">Current deposits are estimated at 16 billion tonnes and are primarily located in three regions of the world: Morocco and Western Sahara, China, and the United States. Global needs are estimated at 150 million tonnes per year, and in Europe, over 90% of the 950,000 tonnes consumed each year are imported. Given the nearly exponential increase in demand, the depletion of phosphate mines (the ore from which phosphorus is extracted) is projected to occur by the end of the 21st century. Recovering phosphorus from treated wastewater in sewage treatment plants alone could cover approximately 15% to 20% of the demand. Phosphorus recycling is of paramount importance as it contributes to optimizing the use of phosphorus, an essential element in the production of phosphate fertilizers, without which it would be impossible to feed the global population.<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-6e6c7f3\" data-id=\"6e6c7f3\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-f5959bc elementor-widget elementor-widget-image\" data-id=\"f5959bc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"837\" height=\"470\" src=\"https:\/\/www.stereau.com\/wp-content\/uploads\/2023\/05\/mine_phosphates.png\" class=\"attachment-large size-large wp-image-5995\" alt=\"Phosphate mining operation.
