For continuous extraction of humic and fulvic acids from peat moss at ~1,000 L/h, I’d recommend alkaline extraction with process intensification using the GlobeCore AVS vortex layer device. AVS significantly accelerates mass transfer and improves yield by activating peat particles in the liquid phase. After AVS, use centrifugation and fine filtration, followed by membrane concentration to obtain a stable liquid extract suitable for fertilizers or additives.

Beyond the equipment already mentioned (AVS machines for intensification, centrifugation, filtration, and membrane concentration), it’s important to consider the overall process logic for continuous production, especially at ~1,000 L
In industrial practice, the extraction of humic and fulvic acids from peat is almost always based on alkaline extraction, since these compounds are soluble in basic media (typically KOH or NaOH solutions). The key challenge is not just to dissolve them, but to do so efficiently and consistently in a continuous flow.
From a process perspective, a robust continuous setup typically includes:
 Raw material preparation (crushing and slurry formation) to increase surface area and ensure stable feeding into the system.
 Intensified extraction stage (e.g., AVS or similar high-energy mixing technology), where mechanical activation significantly accelerates mass transfer and reduces extraction time compared to conventional batch processes.
 Separation stage (centrifugation or decantation followed by filtration) to isolate the liquid phase containing humic and fulvic acids from solid residues.
 Polishing and concentration that often involve the use of membrane systems or evaporation, depending on the desired final concentration and stability.
The key advantage of intensified technologies (such as vortex layer-based or ultrasonic-assisted extraction) is that they can reduce extraction time from hours to minutes while improving yield and reducing reagent consumption, which is essential for continuous operation at an industrial scale.
Another important point is process stability: in continuous systems, maintaining consistent pH, temperature, and solid-to-liquid ratio is critical for achieving uniform product quality. This is where modular configurations (reactor → separator → filtration → concentration) provide better control than simple batch systems.
If you want to see how such process intensification techniques are implemented in practice (including equipment configuration and operating principles), it’s worth reviewing this article: https://globecore.com/milling/humic-fertilizers-production-from-peat/.

Your summary is exactly the right process logic for a continuous, industrial-scale humic/fulvic extraction line; to make it practical for ~1,000 L/h I’ll add the key operating details and control points you’ll need to lock in during engineering and pilot runs. Start with raw-material preparation that delivers a stable, pumpable slurry: crush or mill peat to increase surface area (targeting a consistent particle distribution that feeds reliably through a metering pump), and prepare the slurry at a controlled solids concentration so the downstream AVS and separators see a repeatable load. Use robust positive-displacement feed pumps (progressive cavity or diaphragm) and mass/flow metering so you can maintain a constant solids-to-liquid ratio and accurate alkali dosing; automatic pH and conductivity control in the mixing tank is essential to hold extraction conditions steady in continuous operation.

Run the activated extraction in an AVS loop in either inline or recirculation mode, using the electromagnetic vortex layer to break agglomerates and accelerate mass transfer; tune energy input (kWh/m3), residence time (or number of passes), and loop cooling to avoid overheating and to hit target dissolution in minutes rather than hours. Immediately downstream, remove coarse and heavy minerals with screens and hydrocyclones, then perform more complete phase split with a decanter or clarifier centrifuge to protect membranes. Fine polishing ahead of concentration should include depth or cartridge filtration sized for the expected turbidity and solids load; membrane concentration is usually the preferred final step for a liquid product—start with ultrafiltration to retain high‑molecular‑weight humic fractions and then evaluate nanofiltration if you need higher concentration or partial salt removal. Design CIP/backflush capability, prefiltration stages and a robust anti‑fouling strategy because membrane flux and cleaning frequency will control operating cost.

Operational stability comes from instrumented control and modular redundancy: jacketed tanks and loop heat exchange for temperature control, inline pH/turbidity/viscosity monitoring, and PLC logic to balance AVS throughput, centrifuge feed, and membrane flux. Plan solids handling (dewatered peat cake drying/valorization), washwater recycling and alkali management (recovery or neutralization) to minimize reagent cost and effluent load. Finally, size the AVS unit(s) and separators conservatively or use parallel trains (AVS-100/AVS-150 combinations) so you can handle peaks and perform maintenance without stopping the whole line; run a pilot loop to define exact alkali strength, number of AVS passes, separator cut points and membrane selection before committing to full-scale installation.
