Water restoration for food and beverage processing
A processing line makes a high-strength waste stream, sugars, starches, fats, and wash water, that runs the oxygen demand up fast. When the basin cannot keep up, the sludge stops settling, the plant smells, and the discharge numbers climb, all while aeration runs the power bill. You want the water handled without slowing the line.
The problems we see on your water
Filamentous bulking: sludge that will not settle
When aeration cannot keep up: low dissolved oxygen under load
Headworks and basin odor: hydrogen sulfide off a plant that ran short of oxygen
The energy cost of aeration: paying for oxygen that never dissolves
Wet weather and shock loads: when the demand arrives all at once
What Alchemal installs and takes responsibility for
A food or beverage plant makes a waste stream with a heavy biological load: the sugars, starches, fats, and wash water a processing line sheds carry a high biochemical oxygen demand (BOD, the oxygen the waste demands as it breaks down). That load runs the oxygen demand up fast, and when the basin cannot keep dissolved oxygen (DO, the oxygen carried in the water) at setpoint, the culture slows, the sludge bulks and stops settling, and the plant sours. Nanobubble oxygenation keeps more of the oxygen you supply in the water, so the basin holds its setpoint under a strong load instead of losing it at the surface. It runs continuously, and the line it sits beside keeps running.
The proof is operational. We baseline the dissolved oxygen, the settling readings, and the numbers your discharge permit turns on, then log them against that baseline through the processing season. An N-Series unit you own does the work; the high-organic-load unit is the N4, built for heavy loads with no fine passages to clog. The assessment sizes it to your stream, and where the limit is capacity rather than oxygen it says so; Stewardship carries the record.
What the published work shows, and where we need the field
The mechanism has been measured in a treatment reactor, where nanobubble aeration reached a higher removal of the organic load than a fine-bubble system. The figure, its scope line, and the limit sit on the wastewater overview, attributed to nanobubble aeration as a mechanism rather than to any Alchemal unit. Our own installations publish their own record as case files, and we are looking for processors willing to help build it on a working plant.
Proof from plant managers
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 processors ask
Our waste is high-strength and seasonal. Can this handle it?
A high biochemical oxygen demand (BOD, the oxygen the waste demands as it breaks down) is exactly the load that outruns aeration. Holding oxygen in the water keeps the culture working at that load, and the assessment sizes to it, including the seasonal peaks a processor sees.
We have a bulking and settling problem. Will this help?
Where low oxygen is favoring the filaments that keep sludge from settling, holding oxygen shifts the balance back toward floc that settles. Bulking has other causes too, so we baseline the settling and the DO profile and read whether oxygen is the lever here before sizing anything.
Will installing this slow production?
No. The system installs at the basin as it runs and feeds oxygen continuously. The line, the wash cycles, and the loading schedule all keep going, and nothing is added to the water except oxygen.
Does it help with the plant odor?
Where the odor is sulfide made in water we can keep aerobic, holding oxygen shifts the biology off the path that generates it, so less comes off the surface. Where it is made upstream, the assessment says what a basin reaches and what it does not.
