EM can be used to effectively conrol bad odour and improve the function of waste water. There are usually two issues around waste water that can be problematic:

  • Odour
  • Sludge build-up

EM is very effective at controlling bad odours coming from waste water. Initially this has a rapid suppressing effect, then as the function of the waste water system is restored to a biological one, the odour is not produced at all.

Over time the sludge will reduce and clarity and quality of the water will improve significantly making it suitable for applying to land and crops in many instances. In New Zealand many Wineries are using EM to control odour in their waste water systems.

Below is a testimonial from one of our winery customers who uses EM in their waste water system at a vineyard. As you can see from the below before and after photo, using EM has resulted in cleaner and clearer water, no sludge build up and also complete reduction of odour. 

"I have been using EM in our waste water environment for about 5 years, it has helped us to control odour, reduce sludge build up on pipes and tanks and helps keep our BOD below the required levels. I would recommend everyone try EM and see the results for yourself." - Bruce Walker - Winery Operations Manager Spy Valley Wines
