Water restoration for swine operations
On a hog operation the lagoon is the part the neighbors notice. When it sours, the odor carries on a still evening and the complaint calls follow, and the hydrogen sulfide that builds under a crust becomes a safety matter every time you agitate or pump.
The problems we see on your water
What Alchemal installs and takes responsibility for
On a swine operation the lagoon is where the community relationship lives. When its biology runs out of oxygen the breakdown goes anaerobic, meaning without oxygen, and that turn gives off hydrogen sulfide (H2S, the rotten-egg gas) and ammonia. That is the odor that carries on a still evening, and it is the same gas that builds under a crust and releases in a rush when the lagoon is agitated.
Nanobubble oxygenation keeps the upper column aerobic, so more of the waste breaks down the aerobic way, which produces no sulfide. Less hydrogen sulfide leaves the surface, the sour swing settles, and sludge accumulates more slowly. It runs continuously, and nothing about the operation stops. Oxygenation lowers the standing sulfide load in the water; it does not replace the gas-monitoring and confined-space procedures that govern an agitation day, which is a distinction we keep honest.
We baseline the lagoon before sizing anything, and Stewardship carries the record: odor-complaint counts before and after, hydrogen sulfide readings where you take them, and sludge-depth surveys. The lagoon-duty N4 is built for high organic loads with no fine passages to clog and carries a published target price band, and what we measure and how is published. The published mechanism figure and its scope sit on the agriculture overview, attributed to nanobubble oxygenation rather than to any Alchemal unit.
Proof from swine operators
The first installations for this audience are being instrumented now, and their case files publish when the record is worth reading. The methodology is already public: what we record, how we calibrate, and how we report what didn't move.
From your first note to the assessment
- You describe the water. A specialist reads it, replies with a plain answer, and says whether an assessment makes sense.
- Your water goes on the schedule. The first assessments and installations are being scheduled now; requests are answered in the order they arrive.
- The assessment puts a baseline on paper: dissolved oxygen top to bottom, clarity, the condition of the sediment, and a plan with a prediction attached. If oxygenation isn't the right fix, the report says so.
Questions swine operators ask
Will installing this interrupt the barns or the pit schedule?
No. The system installs at the lagoon as it stands and runs continuously. Loading, pulling pits, and the operating schedule all keep going, and nothing is added to the water except oxygen.
Does this handle the odor the neighbors complain about?
It addresses the cause of it. The rotten-egg odor is hydrogen sulfide that anaerobic breakdown gives off, so keeping the upper column aerobic means less of it leaves the surface. We track odor-complaint counts and gas readings against a baseline rather than promise a number.
What about the hydrogen sulfide risk when we agitate?
Oxygenation lowers the standing sulfide load in the water, but hydrogen sulfide released during agitation and pump-out stays a recognized hazard governed by your gas-monitoring and confined-space procedures. Those still apply on an agitation day regardless of the standing load.
