Process Flow Chart
Closed loop Organics Management System
Excreted Manure
Vacuumed from the Feed Lane & Delivered to the Reception Pit
Holstein Cow Produces Approximately
112 pounds of manure per day
44 pounds of urine per day
Plus feed, bedding and other debris
Manure Pretreatment
Energy Source Plus - pre conditions the manure by adjusting the pH and Electrical Conductivity to preset levels
Instrumentation To Measure pH & EC
Bio-Organic Catalyst Enhances Methane Production
Sand Separator
All harvested feeds contain dirt and grit from the harvesting process.
Our testing and observations indicate approximately One Pound Is Consumed per day per cow and Excreted In the Manure
This is the cause of most digesters to lose temperature and shut down
Holding Tank
Manure in the holding tank is approximately 14% solids
Must be diluted to 8 to 10% solids prior to being fed into the digester
Cheese whey will be added to reduce the solids content and greatly increase biomethane production
Heat Exchanger
CSB Ultra Low NO x Burner Technology
Direct Steam Injection Heater - A Process Device To Inject Steam At Sonic Velocity For Heat Transfer
Heated From A Boiler
Fueled By Methane From The Digester
Anaerobic Digester
An Above Ground Tank or Series of Tanks
Controlled Sludge Blanket
Complete Mix
High Solids Content - 8 to 10%
Shortest HRT High Solids Digester On the Market - <7 days.
Anaerobic Digester
Can Be Operated at Mesophillic 95º F or Thermophillic 125º F Temperatures 55 -60 %Volatile Solids Destruction 600 + BTU Methane Small Footprint Expandable and Movable Anti-botics Can’t Shut The Whole Digester Down
Biomethane
Pumped from the Digester To Water Bath Scrubber
Fed To Co-Generation Equipment
Preheat Influent - Manure Feed Stock For Digester
Gas Conditioned PSA Technology
Biomethane
The Majority of Biomethane Production Pumped To Storage Vessel
Plasma Technology Kills Pathogens, Viruses & Microbes
Stattler Double Membrane Biogas Storage Tank
Hauled By Tube Trailer Off Site Inserted Into the Utility Pipeline
Gas Flare
A Gas Flare Is Installed as a Safety Device
Gas Scrubber Processes Any Biomethane Prior to Flaring
Two Disruptive Technologies
Tri-Pac Power Factor Correction - can save in excess of 15% of Dairy Power Demand
Adsorption Chiller - requires no electrical service
Operates from Hot Water - Saves up to 23% of Dairy Power Requirement
Co-Generation
Generate Power Requirement For The Dairy
Properly sized Generator For Summer Operations Will Have Surplus Power At Least Seven Months of the Year Sell Surplus Back to the Utility Grid
Hot Water Provided to Adsorption Chiller
Combined Heat, Power, & Cooling
Hot Water From The Gen-Set Engine or Boiler Fed To Adsorption Chiller 184º F Water Will Chill Milk To 38º F
Exhaust Gas Can Be Employed To Heat Water For Wash Down of Parlor and Equipment
Digester Effluent
Discharged Effluent - 4% Solids Effluent Discharged at the Same Rate as Manure Input Discharge Temperature 95º F Effluent To Holding Tank Manure To Auger Separator Manure Solids to Mixer Station Manure Water <1% Solids To Algae Farm
Separated Manure Solids
Manure Solids - Four Auger Mixer
Carbon Sources Added for 30 to 1 Carbon/Nitrogen Ratio
Input Into Aerobic Bioreactor
Superior Soil Amendment - High Market Value
Aerobic Bioreactor
In-Vessel Composting Technology
Patented Process -<72 Hours
Material is Pasteurized, Weed Seed Free, Odor Free, Nutrient Rich
High Value Compost for Landscaping
Employed For Bedding By Dairies
Sold As A Soil Amendment
Computer Controlled
Each of the Components are Computer Controlled and Monitored
Each Technology can be Installed & Operated as a Stand Alone System
Data Is Collected For Renewable Energy Credits
All Data Is Auditable
Closed loop System
Provides New Sources of Revenue Substantial Avoided Costs System May Be Monitored and Controlled Remotely - Better Control and Less Management Time Reduces Dairy Operating Costs Reduces/Eliminates Regulatory Compliance Costs
