Digest-it for Effluent

Formulated to improve the breakdown of solids, and the retention of nutrients in captured animal effluent. It provides a range of food sources and metabolites that promote aerobic digestion in effluent streams.

Digest-it for Effluent (formulated for both pond use and compost/manure piles) or Digest-it for Dairies (formulated for pond use only) are produced by fermentation of microbial cultures and contain a rich source of vitamins, minerals, proteins, enzymes, amino acids, carbohydrates, and growth promoters. In effect, Digest-it provides a rich food source for aerobic microbial species. It aims to create and maintain a balanced microbial environment in effluent ponds, stimulating aerobic microbial digestion of organic matter.

Non-performing effluent systems are instantly recognisable by the presence of persistent surface crusting and their pervasive odour. The depletion of oxygen in the water, combined with a lack of sunlight, reduces microbial digestion. The proliferation of anaerobic bacteria can increase hydrogen sulphide (i.e. rotten egg gas), ammonia gas, and increased pH (i.e. alkalinity).

Use of Digest-it for Effluent or Dairies will result in a number of physical and chemical changes in ponds within four to six weeks of treatment, including the breakdown of crust and the dissolution of sediment. The time taken for these changes to occur will depend on several factors, such as the quantity of solids, weather conditions etc.

  • Reduces losses of nitrogen and sulphur as gasses to atmosphere
  • Stimulates aerobic microbial activity in effluent ponds
  • Digests suspended solids into plant-available liquid nutrients
  • Reduces turbidity and increases the liquids to solids ratio
  • Reduces surface crusting, solid waste and the need for desludging
  • Reduces unpleasant odours
  • Reduces Biological Oxygen Demand (BOD) of resulting waste streams
  • Reduces withholding periods after application of waste streams to pastures
  • Can also be used as a silage inoculant or to reduce odours in stock bedding
  • Can be used as a shed floor or dairy floor inoculant
  • BioAg Digest-it for Effluent or Dairies are a certified organic input

BioAg’s Digest-it is widely used in Ireland and the United Kingdom (as Digest-it and Slurry Mate), across more than 1,000 dairy farms. It is also sold in South Korea (as Digest-it Sludge Zero).

Made here in Australia in our Narrandera NSW plant, BioAg exports significant quantities of Digest-it each year to overseas markets.

Digest-it for Effluent resources

  • Dairy case study, Merrigum VIC

    The creation of an active and stabilised microbial population in an effluent pond on one northern Victorian dairy farm has all but eliminated a half-metre-thick, stinking surface crust and significantly increased its operating capacity. Kevin Fitzsimmons and his wife, F...

  • Dairy case study, Katunga VIC

    A Northern Victorian dairy farmer is gradually eliminating a football field-sized crust on his effluent pond by using a new 'biologically active' microbial culture. Maarten and Sharon van Tilborg milk 610 Holstein, Jersey and crossbred cows, producing 4.5 million litres...

  • Dairy case study, Mount Gambier SA

    The use of a ‘biologically active’ microbial culture is playing a small but significant role in helping to turn seven megalitres of liquid waste into $150,000 worth of nutrients, on one of Australia’s largest dairying operations. James Mann and his wife, Robyn, milk alm...

  • Dairy case study, Torrumbarry VIC

    A belching effluent pond is a beautiful sight for people who know what it means. For Scott and Jade Sieben it is money in the bank. The couple milk 250 cows at Torrumbarry, 20 minutes from Echuca, in northern Victoria. The couple’s 250-cow herd, which includes 30 percen...
