SPELFilter: Water Quality Outcomes & Heavy Metal Removal

Heavy metal removal is a leading requirement for stormwater filtration across the New Zealand region, and SPEL’s flagship device for water quality applications is the SPELFilter. With proven heavy metal removal efficacy, this innovative device is currently approved for use across Auckland, Waikato and Christchurch regions.

Stormwater events often result in the conveyance of heavy metals, particularly in industrial areas and car parks – with typical pollutants including copper, aluminium, nickel, and mercury. Accompanying the SPELFilter, SPEL Stormwater offers a versatile range of devices to accommodate your site needs including the Hydrochannel, SPELBasin & Hydrosystem.

Dissolved heavy metals are dangerous compounds when it comes to our local ecology. Traditional filtration often removes particulate heavy metals – but may not be as effective when it comes to dissolved heavy metals. With a full scope of stormwater treatment systems to help remove these ‘nasty’ environmental contaminants, SPEL can help you meet your sustainability outcomes and environmental objectives on-site.

Ensuring these outcomes is particularly relevant to the New Zealand marketplace, as heavy metals and stormwater contaminants are pollutants of concern – and require management in accordance with local environmental protocols.

SPELFilter: Tackling Stormwater Filtration Requirements

Heavy metal removal rates vary by inlet concentration and application, and our knowledgeable team can help you to specify appropriate stormwater treatment configurations to meet your application and design specifications.

SPELFilter is a versatile and innovative system that can be tailored to a range of on-site scenarios. Supported by SQIDEP verification through Stormwater Australia’s rigorous standards – SPELFilter’s confirmed data shows pollution removal rates of 85% TSS (Total Suspended Solids), 74% TP (Total Phosphorus) and 59% TN (Total Nitrogen).
