ATD’s 2 – Step System™

Description

ATD Tackles Adaptation to Climate Change for Dairies

ATD’s 2 – Step System™ will help to put the right nutrition and moisture where and when it is needed.

ATD presents a 2–Step system™ for the management of livestock manures that is cost-effective, efficient, and environmentally friendly. The system captures and concentrates virtually all nutrients (solid, liquid, and gas) daily for storage or sale above ground to reduce hauling costs significantly and, optionally, daily water demand. By separating nutrition from hydration, you will have more nutrients per tonne in lighter loads and irrigation-quality water year-round to match your crop needs.

ATD’s Step 1

We capture virtually all suspended solids daily with our Rotary Press and Clarifier and store them above ground.  Solids will be compact, lighter, and cheaper to apply.  It runs unattended.

The solids-free effluent is recycled to collect manure again with the rest sent to the Lagoon where more may be added direct from your source.  The Lagoon holds dissolved solids but will now create less GHG’s, won’t need agitation or an annual pump-out.

Benefits of Step 1 – the low hanging fruit!

• Solids weight and volume are reduced. Nutrients/tonne are increased five-fold.
• Daily solids separation reduces Phosphorus transfer to the liquid stream. Solids can be distributed more accurately to meet the Environmental Farm Plan.
• Soil compaction is reduced by lighter loads. Dryer solids can be applied with simple equipment to improve operational flexibility.
• Labour and fuel costs to distribute and apply solids are reduced.
• Barn air quality improved, Nitrogen saved, and struvite production is reduced.
• The Lagoon will hold a little more water with the solids removed and it can be enlarged to collect any newly available water.
• The Lagoon will no longer produce Carbon Dioxide or Methane, thereby eliminating a major source of farm emissions.
• Add Fresh Water equal to the recycled flush water direct to your Lagoon or reduce demand on your source.
• Optionally Install a floating solar power array on the Lagoon. Reduce evaporation losses and improve sustainability.
• Reduce transportation costs of solids to and from hub digesters.

This is what happens to your solids at the Digester

The Farm Rotary Press discharges 30% Dry Matter to a trailer for delivery to the Digester to be eventually discharged as digestate to the Hub Rotary Press. The Hub Rotary Press discharges 30% solids to a trailer to be returned to the dairy for storage above ground and the Press effluent goes to the Hub Clarifier and TDS concentrator to be discharged as concentrate to a tanker trailer to be returned to you for storage. The Concentrator’s clean water will dilute the next load at the digester.

ATD’s Step 2

Should water restrictions or water costs increase, install Step 2.

• Recycle more water and optionally improve it to drinking water standard.
• Capture and increase TDS and Ammonia for storage.
• This introduces new technology to the farm.

Benefits of Step 2

• TDS and Ammonia capture and concentration improves placement accuracy, reduces application costs and increases sales value.
• Reduces demand on aquifer by up to 60%.
• Irrigation volume is increased if surface water can be captured off-season to supplement lagoon contents.
• Potential recovery of some investment by sale of recycled water to unlicensed neighbor.
• Cleaner floors and cleaner barn air when flushed with recycled drinking water.

At What Cost?

Every farm is unique, requiring a customized solution:

• ATD’s Project Cost Estimates will be based on the Confidential Farm Data you enter on our Farm Facts Questionnaire.
• Download and complete our Farm Facts Questionnaire and Mutual Non-Disclosure Agreement, return them to ATD with any questions you may have to discuss the next steps.
