All businesses produce wastewater of some kind. The content of the wastewater varies from industry to industry. Depending on the content and quality, this wastewater can either be discharged directly into the local sewer, or held in retention areas for treatment before being discharged or taken away for further treatment. Typical retention areas are effluent ponds, catchment ponds, septic tanks and grease traps.

The key element in breaking down human, animal and organic waste in wastewater is having large volumes of high quality, beneficial, bacteria. By using ETG bacterial based products, clients can ensure compliance with wastewater legal regulatory levels relating to;

• Biochemical oxygen demand
• Chemical oxygen demand
• Total suspended solids
• Oils and grease
• Total biological phosphorus, nitrates, nitrites and ammonia
• Faecal coliforms
• Odour

Because of water costs and licence conditions, industries seek to recycle wastewater or improve it to a suitable standard, after which it can be used for irrigation, wash downs, dust suppression etc. The waste landfill industry is successfully recycling its wastewater (leachate) and adding ETG products to create a ‘bio-reactor’. The cost savings are significant because they no longer need to purchase additional water or pay for the removal of wastewater. In addition, ammonia levels are reduced and toxic odours eliminated, much to the relief of site staff and surrounding residents.
