The ATD Manure System
Recycles Flush and Wash waters to reduce handling costs.
The ATD Manure System takes the manure daily and after initial processing for bedding or solids for transport will collect and discharge the remaining Suspended Solids with a concentrate of the Dissolved Solids and Nitrogen fertilizer to your Lagoon while returning clean, disinfected, drinking quality water to replenish the flush and wash water systems in the barns.
The result will be a significantly lower demand on your daily fresh water supplies, reduced lagoon volume with stronger nutrient values and the ability to upgrade freshwater quality if needed.
Examples of a dairy farm with presses installed:
| ONE PRESS INSTALLED: | Input L/day | Output L/day |
| Manure produced to Lagoon 12% solids | 17,000 | |
| Add Flushing to bring solids to 6% | 17,000 | |
| Drier solids under cover | 1,967 | |
| Flush water returned | 17,000 | |
| Wash water returned | 5,544 | |
| TDS concentrate to storage | 2,507 | |
| Lagoon storage | 6,982 | |
| TOTAL | 34,000 | 34,000 |
| Reduction in freshwater demand | 22,544 | L/day |
| Reduction in lagoon volume, new TSS | 72% | 14% |
| TWO PRESSES INSTALLED: | Input L/day | Output L/day |
| Manure produced to Lagoon 12% solids | 17,000 | |
| Add Flushing to bring solids to 6% | 17,000 | |
| Drier solids under cover | 3,327 | |
| Flush water returned | 17,000 | |
| Wash water returned | 5,544 | |
| TDS concentrate to storage | 2,507 | |
| Lagoon storage | 5,622 | |
| TOTAL | 34,000 | 34,000 |
| Reduction in freshwater demand | 22,544 | L/day |
| Reduction in lagoon volume, new TSS | 76% | 11.3% |
Example of a hog farm:
| Present Lagoon Contents | 97.8% | 2.2% | L/day | |
| Liquids | Solids | Total | ||
| Feed to ATD system | 97,800 | 2,200 | 100,000 | |
| Solids to Lagoon @23% DM | 7,365 | 2,200 | 9,565 | |
| Feed to RO | 90,435 | |||
| TDS concentrate to Lagoon | 10% | 9,043 | 9,043 | |
| Recycled | 81,391 | 81,391 | ||
| All nutrients in less volume uses less fresh water | Solids | Total | ||
| Old lagoon | 2.2% | 100,000 | ||
| New Lagoon, % Reduction, new TSS | 81.4% | 11.8% | 18,609 | |
| Reduction in daily fresh water L/day | 81,391 | |||
This reduction in freshwater demand conserves a natural resource and reduces field time and costs while retaining nutrients in a more easily distributed form.
Advantages with the ATD Dairy and Pork Manure Management System
At present, any move to expand or consolidate livestock operations has been inhibited by the cost to collect, store, and apply manure nutrients. There are moratoriums on new construction and citizen push back at hearings for new operations and now climate change is making it nearly impossible for some farmers to water their livestock. However, adaptations of existing technology now offer solutions – extract fresh water from the manure daily, reducing farm consumption by up to 50% and prepare everything else for other uses or sale off-site.
FEATURES
Can be installed in steps to suit time and budget
Time tested equipment from International Suppliers
Operates effectively in most climates
Can be adapted for digester operations
Adapts to installed solids separation equipment
Flush pits refilled daily with filtered water
Requires less space than biological treatments
Automated operation with remote support from suppliers
BENEFITS
Increased sustainability and the protection of legacy farm values
Reduces farm fresh water requirements by up to 50%
Reduces field time, compaction and fuel costs
Provides opportunity for new cash flow
Allows herd expansion on the same acreage if nutrient balance maintained
Eliminates slurry application and safety concerns in favour of manure solids and concentrate
Daily treatment reduces odours
Recognizes improved environmental management and husbandry
Improves air quality for healthier animals and staff
Reduces exposure to regulatory sanctions and adverse public opinion associated with manure management
