03 / How the solution works
How the solution works
Livestock projects begin by separating the different streams and defining an outlet for every product. Manure or slurry, barn-wash water, and domestic wastewater can have very different solids and organic loads, so they should not automatically enter one treatment unit.
Screening, grit removal, equalization, and solid–liquid separation stabilize the feed.
A CSTR can suit pumpable higher-solids slurry, while USR, UASB, or other anaerobic configurations may suit different feed characteristics. The gas line then removes condensate and hydrogen sulfide as required before storage, flare, boiler, power, or upgrading interfaces; wastewater and digestate receive separate post-treatment and reuse routes.
Featured Application
Livestock wastewater treatment and biogas recovery.
Huida develops integrated treatment trains for pig, dairy, and poultry operations. We coordinate wastewater control, anaerobic digestion, gas conditioning, downstream polishing, and digestate management around the farm’s actual collection method, climate, land, and energy-use conditions.
Recover and handle biogas safely
Select USR, CSTR, UASB, or another suitable anaerobic configuration from solids content and organic loading, then coordinate heating or mixing, gas collection, condensate removal, desulfurization, storage, flare, and utilization interfaces.
Plan every outlet
Match aerobic polishing, clarification, filtration, disinfection, reuse, or discharge to the water target, while coordinating digestate separation, storage, composting, or land application with local nutrient and seasonal capacity.

Feedstock & wastewater line
Collection zoning, screens, grit removal, equalization, pumps, piping, odor interfaces, and solid–liquid separation selected for the manure-handling method.
Digester & auxiliaries
Reactor selection, feed distribution, mixing or recirculation, heating, insulation, level and temperature control, sludge withdrawal, and maintenance access.
Gas line & safety
Condensate control, gas–water separation, desulfurization, pressure control, storage, gas detection, emergency isolation, flare, and boiler or power-generation interface as required.
Digestate & effluent line
Post-treatment, separation, storage, dewatering, disinfection, reuse, discharge, composting, or land-application interfaces defined for the local outlet route.
04 / Process
Typical process configuration
Map streams & outlets
Confirm livestock type, headcount, housing, manure collection, wash schedule, seasonal flow, and the intended water, energy, and nutrient outlets.
Pretreat & balance
Separate unsuitable materials, remove coarse solids and grit, equalize flow, and apply solid–liquid separation where it improves digestion or downstream treatment.
Digest & condition gas
Select and operate the anaerobic reactor around solids, loading, temperature, mixing, and retention needs; then manage condensate, sulfur, pressure, storage, flare, and use interfaces.
Polish & recover
Treat wash water and liquid digestate for the agreed discharge or reuse route, while coordinating separated solids, storage, composting, or land application.

06 / Project Value
Engineering advantages
One coordinated material balance
Water, solids, gas, heat, and nutrient routes are sized together so that one outlet does not become another operating bottleneck.
Reactor matched to the feed
The anaerobic configuration is selected from solids content, pumpability, organic loading, temperature, and mixing needs instead of using one reactor for every farm.
Safer gas handling
Condensate, hydrogen sulfide, pressure, storage, flare, detection, and isolation are addressed as an integrated gas system.
Reuse planned from the beginning
Effluent and digestate routes are developed around actual land, crop, storage, season, discharge, and local acceptance conditions.
