Virotec ViroSewage technology

ViroSewage technology is easily integrated into existing sewage treatment facilities and may be successfully applied to both biological nutrient reduction (BNR) and trickle filter treatment plants using a relatively simple engineering retrofit and the application of ViroSewage reagents.

The technology delivers good results, including: substantial odour reduction minimising local impacts from sewage treatment facilities; reduced residence time in the final clarifier potentially allowing existing plants to significantly increase capacity without substantial increase in capital expenditure; economically achievable removal of up to 99.9% of phosphorus; removal of heavy metal, reduction of BOD and TSS in the effluent stream and other contaminants; and biosolids that are free from objectionable odour, phosphate enriched and environmentally safe due to unmatched heavy metal immobilisation.

Virotec has recently won contracts from Queensland Urban Utilities for the installation of ViroSewage Technology, including the Beaudesert sewage treatment facility. This adds to the growing number of regional councils that are using the benefits of this technology. The use of ViroSewage Technology at Beaudesert has resulted in substantially reduced phosphate levels and an improvement in overall water quality.
