Used as stand-alone packages, or with Dry Media polishing filters, ERG's bio-scrubbers provide trouble-free odour control for highly contaminated, small gas flows (<3,000m3/hr) emanating from waste water treatment processes.
ERG's bio-scrubbers are filled with durable, bio-inert pumice media, and are specifically designed to provide outstanding value for money and simple operation. Our bio-scrubbers need only a filtered final effluent supply and a drain connection - there is no requirement to dose chemicals into the bio-scrubber, and so the SHE (Safety, Health and Environmental) issues associated with their delivery and storage on site is removed.
A specially selected cocktail of bacteria, enzymes and nutrients are pre-seeded in the bio-scrubber to ensure rapid development of the odour neutralising bacteria which colonise the pumice bio-media. The bacteria digest the odour-causing compounds, which typically include H2S, mercaptans, organic sulphides and ammonia. The optimised environment for bacterial activity is maintained by controlled irrigation with filtered final effluent, or water dosed with low level nutrients if no final effluent is available.
Designed and built to BS4994 and fully compliant with WIMES 8.05, ERG's bio-scrubber systems offer assured performance and competitive costing.
All our systems are custom-designed for the odour control duty required, and include a vessel and irrigation system, biomedia, air extraction fan and ductwork, and electrical control panel.
The key advantages of ERG bio-scrubbers are:
