Facility Overview
Facility Type: Commercial swine production operation
Waste System: Anaerobic manure lagoon
Primary Challenge: Solids accumulation reducing lagoon capacity
Swine production facilities rely on anaerobic lagoons to manage large volumes of manure and organic waste. Over time, undigested solids accumulate on the lagoon bottom, gradually reducing treatment capacity and increasing odor and management challenges.
At this facility, long-term solids buildup had begun to significantly reduce the lagoon’s effective treatment volume.
The Challenge: Manure Lagoon Solids Accumulation
Manure lagoons gradually accumulate organic solids as manure, feed residue, and bedding materials settle and compact over time. Similar biological processes occur in municipal wastewater lagoons, where sludge accumulation in wastewater lagoons can gradually reduce treatment capacity.
Without intervention, this buildup can lead to several operational challenges:
- reduced lagoon storage capacity
- increased sludge depth
- higher risk of lagoon overflow during heavy rainfall
- increased odor generation
- more frequent lagoon pumping requirements
These issues are common across swine, dairy, and cattle operations using lagoon-based manure management systems.
Biological Treatment Approach
To address the solids buildup, the facility implemented a biological lagoon treatment program using ManureMagic, a microbial-based product designed to accelerate the breakdown of organic solids in agricultural waste systems.
ManureMagic introduces specialized bacteria that enhance the natural biological digestion already occurring in manure lagoons.
The goal of the treatment program was to:
- accelerate decomposition of organic solids
- reduce sludge accumulation
- restore lagoon treatment capacity
- stabilize lagoon performance
Observed Lagoon Improvements
The lagoon showed visible improvements in surface conditions and solids reduction after treatment.
Following implementation of the treatment program, the facility began observing improvements in lagoon conditions.
Reported improvements included:
- noticeable reduction in lagoon sludge accumulation
- improved manure digestion within the lagoon
- better lagoon operating conditions
- reduced solids buildup over time
Biological digestion gradually converts organic sludge into simpler compounds such as carbon dioxide, methane, and water, reducing the total solids volume within the lagoon.
Why Solids Accumulation Matters in Swine Lagoons
When solids accumulate in manure lagoons, several operational problems can develop.
As sludge depth increases:
- lagoon storage capacity decreases
- manure pumping schedules become more frequent
- treatment performance declines
- odor events can increase
Managing lagoon solids is therefore a critical part of long-term manure management planning.
When Swine Producers Should Evaluate Lagoon Solids
Producers operating manure lagoons may want to evaluate lagoon sludge conditions if they notice:
- visible solids buildup in the lagoon
- reduced lagoon storage capacity
- increased manure pumping frequency
- stronger lagoon odors
- signs of lagoon aging or reduced treatment performance
Environmental conditions such as temperature can also influence biological activity and sludge digestion within lagoon systems. Early intervention can help restore lagoon capacity and extend the operational life of manure storage systems.
Request a Lagoon Sludge Assessment
Every manure lagoon accumulates solids differently depending on herd size, feeding practices, lagoon design, and operating history.
A technical lagoon evaluation can help determine:
- sludge accumulation levels
- lagoon treatment performance
- opportunities to reduce solids buildup
- strategies to extend lagoon lifespan
