How We Help Livestock Farms Treat High-Solids Organic Wastewater with Anaerobic Technologies

Global livestock inventories such as swine remain stable, yet the pressure to manage manure sustainably continues to grow. The US has developed technical models represented by integrated crop-livestock systems with on-field application and Comprehensive Nutrient Management Plans; Denmark, the Netherlands, and others have developed centralized biogas projects with digestate application systems.

China's large-scale farms still have considerable room for improvement in supporting biogas project coverage, and digestate resource utilization rates lag behind advanced European levels. Greenhouse gas emissions from livestock account for a significant proportion of total global anthropogenic emissions, making manure management a critical battleground for agricultural carbon reduction. Latin American countries started later in manure management but are accelerating relevant infrastructure development. Against this backdrop, selecting the right Anaerobic Technologies and a reliable EPC Solutions partner has become essential for farms aiming to turn waste into value.

What Is the USR Process?

USR, or Upflow Solids Reactor, is an upflow anaerobic process modified for high-suspended-solids, high-solids organic wastewater, specifically designed to solve problems of clogging, sludge washout, and uneven reaction common in traditional anaerobic processes for high-solids wastewater. The process eliminates complex three-phase separators, simplifies internal structure, and relies on upflow hydraulics to promote thorough mixing of solid materials and anaerobic sludge. No strict granular sludge formation conditions are required-flocculent sludge can operate stably. The key feature is high solids tolerance and impurity resistance, with very high influent suspended solids tolerance. It is a dedicated high-efficiency anaerobic process for livestock manure, agricultural organic waste, and high-solids livestock wastewater, specifically developed for agricultural and environmental applications.

Where Livestock Wastewater Comes From

Livestock wastewater is the core agricultural pollution wastewater from large-scale poultry, livestock, and aquaculture operations, generated primarily during farming operations and facility cleaning. Poultry and livestock wastewater is the main component, including wash water from pig, cattle, and poultry housing, manure and urine seepage, and facility washdown-rich in livestock metabolic residues. Aquaculture wastewater comes from periodic pond water exchange and pond cleaning, with feed residues and metabolic waste as pollutants. Wastewater is primarily generated in peri-urban and rural farming areas. Small-scale farmers lack adequate collection facilities, with wastewater discharged directly to land and water. Large-scale farms have collection systems for centralized treatment, with water production varying with production cycles and cleaning frequency. Understanding these sources is the first step in designing effective Anaerobic Technologies and tailored EPC Solutions.

Professional Construction Team Manpower Reserve

Center Enamel has established its own domestic and international certified construction teams, with regular practical training on GFS tank installation and overseas construction standards for various countries. Domestically, regional construction teams cover multiple zones, capable of simultaneously deploying multiple teams for large tank farm projects. Internationally, cross-border professional installation teams are equipped to various country construction standards-sufficient manpower reserves ensure uninterrupted construction delivery for remote African sites, high-standard European/American facilities, and other projects.

Center Enamel R&D Team

Center Enamel has built a full-chain professional team covering R&D, design, marketing, installation, and after-sales. The R&D team is led by national-level materials technology experts, specializing in enamel frit and tank anti-corrosion core technologies. External senior environmental engineering and mechanical structure engineers are retained to strengthen R&D capabilities, focusing on anti-corrosion coating formulations, specialty corrosion-resistant tanks, and anaerobic supporting integrated equipment-continuously breaking through industry technological barriers.

The team operates through proprietary laboratories with external university research collaboration-conducting year-round new material and new process durability pilot testing and long-term corrosion simulation testing. Specialized enamel formulations are iteratively developed for extreme conditions such as high-salinity wastewater, strong acid/alkali POME, and high-organic livestock manure-providing core technical support for the company's annual new invention and utility patents-building a proprietary material technology barrier.

Innovative Material Technology

Center Enamel has independently developed over 200 anti-corrosion enamel formulations, with proprietary double-sided double-layer enameling technology-GFS tank anti-corrosion service life exceeds 30 years-far surpassing concrete and ordinary equipment-suitable for global high-corrosion wastewater and biogas fermentation conditions.
