# Water restoration for dairy operations

A dairy moves water every day, and the lagoon takes the alley flush and the parlor washdown along with the manure. When it sours, the odor reaches the neighbors, the crust and sludge slow the pumping you schedule around cropping, and the nutrients you count on for the fields get harder to read.

## The problems we see on your water

- [Lagoon odor and sludge: keep the column aerobic Odor complaints, crusting, and sludge that makes pumping harder. One anaerobic cause sits behind all three.](https://alchemal.com/problems/lagoon-odor-sludge/)
- [Lagoon surface crust and lost freeboard: the anaerobic column beneath A hardening surface crust that traps gas, fouls pumping, and eats into freeboard sits over an anaerobic column. See how oxygen addresses the biology beneath the mat.](https://alchemal.com/problems/lagoon-surface-crust/)
- [Lagoon sludge and lost capacity: the slow anaerobic digest Sludge that eats capacity and makes each pump-out harder is the load an anaerobic lagoon never finished digesting. See how oxygen speeds the breakdown so less settles.](https://alchemal.com/problems/lagoon-sludge-capacity-pumpout/)
- [Lagoon BOD and nutrient load: readings a permit turns on BOD and nutrient readings are what a lagoon permit turns on, and an anaerobic lagoon runs them high. See how an aerobic column brings the biological load down, measured against a baseline.](https://alchemal.com/problems/lagoon-bod-nutrient-permits/)

## What Alchemal installs and takes responsibility for

A dairy lagoon carries a working load all year: the manure, the alley flush, and the parlor washdown together. When its biology runs out of oxygen, the breakdown goes anaerobic, meaning without oxygen, and that single shift is behind the rotten-egg odor the neighbors call about, the crust and sludge that slow pumping, and the high biological load your readings carry.

Nanobubble oxygenation keeps the upper column aerobic, so waste breaks down instead of souring: less hydrogen sulfide (H2S, the rotten-egg gas) leaving the surface, slower sludge accumulation, and a biological load that comes down against the baseline. It runs continuously, and nothing about the operation stops. Where the water is land-applied, keeping the column aerobic can change the nitrogen forms, so we measure them rather than promise a result, and your nutrient management plan governs throughout.

We baseline the lagoon before sizing anything, and [Stewardship](https://alchemal.com/stewardship/) carries the record from there: odor-complaint counts, sludge-depth surveys, and the readings themselves. The lagoon-duty [N4](https://alchemal.com/technology/n-series/n4/) is built for high organic loads with no fine passages to clog, and [what we measure and how](https://alchemal.com/technology/how-we-measure/) is published. The published mechanism figure and its scope sit on the [livestock overview](https://alchemal.com/livestock/), attributed to nanobubble oxygenation rather than to any Alchemal unit.

## Proof from dairy operators

The first installations for this audience are being instrumented now, and their case files publish when the record is worth reading. The [methodology](https://alchemal.com/technology/how-we-measure/) is already public: what we record, how we calibrate, and how we report what didn't move.

## From your first note to the assessment

1. You describe the water. A specialist reads it, replies in writing, and says whether an assessment makes sense.
2. Your water goes on the schedule. The first assessments and installations are being scheduled now; requests are answered in the order they arrive.
3. 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 dairy operators ask

**Will installing this interrupt milking or the flush schedule?**

No. The system installs at the lagoon as it stands and runs continuously. The flush, the washdown, and the loading schedule all keep going, and nothing is added to the water except oxygen.

**How does this fit our nutrient management plan?**

Your plan governs, and we integrate with it rather than replace it. Keeping the column aerobic can shift the nitrogen forms in the water, which matters for land application, so we measure the forms against a baseline rather than predict them, and the readings are built for an inspector.

**How do you size a system for our lagoon?**

The assessment reads the load the herd and the flush put on the lagoon and sizes to hold the upper column aerobic at that load. A heavily loaded lagoon needs a load-matched size; an under-sized system fails, so we will not quote one to win on price.

## Start with a conversation.

Describe the water and a specialist replies in writing, before any commitment. Your water, your numbers.
