Float and Unit Installation

DionErgy’s products sit on floats and push air into waste liquid, such as slurry. The effect is to reduce nutrients, such as phosphorous, in slurry, which is of great value to piggery managers as it reduces the size of the land bank they must maintain and thus simplifies their nutrient management planning. Our solutions were developed based on what we learned from the treatment of anaerobic sludges in our own trials and from similar academic research in the US. DionErgy’s products create an environment in slurry in which odours dissipate and solid content and nutrients diminish significantly.


Solution Benefits

  • No downtime as units are retro-fitted without requiring the emptying of tanks
  • Minimal annual operating costs. DionErgy, units run on 0.75 kw and 2.2 kw motors
  • Immediately operational. DionErgy products generally installed within a 2-3 hour timeframe

DionErgy offers rental and sales options.

Characteristics of aerobic sludge digestion

  • Active sludge is kept in an aerobic environment without feed
  • Volatile solids concentration in tanks is reduced and
  • The oxygen provided is consumed

Benefits include

  • Sludge stabilisation – removal of odours
  • Decanting of liquids from solids, significantly reducing volume of solids for treatment and disposal
  • Significant reduction in transportation and gate costs for waste sludge disposal
  • Significantly reduced energy consumption and nominal maintenance costs
  • No downtime – pop in, pop out unit

Site-specific factors that need to be considered when selecting the most appropriate Dionergy product for aerobic sludge digestion include

  • Estimated quantities to be processed
  • Oxygen requirement based on quantities
  • Sludge Retention time
  • Solids loading rates
  • Efficiency required (volumes digested)

Characteristics of aeration in both open and slatted tanks

  • Reduction of total solids, nitrogen and phosphorus
  • Stabilisation of volatile solids in the slurry - removing odours
  • Minimise risks from Hydrogen Sulphide (H2S) poisoning


  • Reduced ratio of nutrients (ammonia and phosphorous) in slurry by volume
  • Pre-plan spreading by controlling solids volumes
  • Installation at agitation points enables mobility across tanks
  • Treated slurry is immediately bio available to grass (breakdown occurs in tanks), reducing the risk of run off

Site-specific factors that need to be considered when selecting the most appropriate Dionery product for nutrient management planning include:

  • Slurry quantities to be processed
  • Slurry age and storage time
  • Existing NH3, P levels in soil
  • Desired P and NH3 levels in slurry and volatile solids content
  • Desired levels of nitrate reduction
  • Oxygen requirement based on above
  • Slurry retention time and type of tanks
