This novel approach to the remediation of dredged sediments results in 100% neutralisation of acidity, the fixing in a non-leachable form of any metals present, more than 99% removal of all metal contaminants in leach waters and the stabilisation of any nutrients present.<\/p>\n
In the ViroSoil technology, a reagent known as ViroBind is central to the process; its application effectively neutralises acidity long-term and any metals present are bound tightly in a non-leachable form.<\/p>\n
The treatment solution also adds nutrients to the soil or spoil, creating an improved soil profile capable of supporting vegetative growth without the risk of metal uptake or acid generation in the future. This allows the potential for the creation of useable soils from previously barren and contaminated materials.<\/p>\n
ViroSoil is easily applied in situ and is extremely effective for the processing of contaminated acidic dredge spoils. Application of ViroBind to dredgings during the dewatering stage on land will counter the tendency to generate acidity as the spoils become exposed to air and oxidise, converting acidic and metal leaching materials into stable sediments with minimal impact on the surrounding environment.<\/p>\n
As Virotec points out, in addition to the remediation of various environmental contaminants, treated soil and sediment can produce a valuable by-product. By altering the physical and chemical composition of dredged sediment, a conditioned soil mix can be produced which has commercial resale value.<\/p>\n","protected":false},"excerpt":{"rendered":"
An innovative treatment solution for contaminated sediment has been developed by Virotec Europe in the UK, which believes that the problems associated with contaminated sediment – including acidity and heavy metals – can be effectively decontaminated in the long-term using the companys ViroSoil technology. \u00a0<\/p>\n","protected":false},"author":8,"featured_media":3116,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[14,15],"tags":[],"sponsor":[],"class_list":["post-3115","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-equipment","category-products-services"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/posts\/3115","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/comments?post=3115"}],"version-history":[{"count":1,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/posts\/3115\/revisions"}],"predecessor-version":[{"id":3117,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/posts\/3115\/revisions\/3117"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/media\/3116"}],"wp:attachment":[{"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/media?parent=3115"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/categories?post=3115"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/tags?post=3115"},{"taxonomy":"sponsor","embeddable":true,"href":"https:\/\/www.portstrategy.com\/coastlink\/wp-json\/wp\/v2\/sponsor?post=3115"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
