How We Help Livestock Farms Treat High-Solids Wastewater with EPC Contractor Expertise

The global livestock manure treatment policy system, with the US and EU as typical representatives, is shifting from end-of-pipe treatment to full-process nutrient management. This regulatory shift is reshaping how farms approach manure management worldwide. The US establishes a manure management framework covering the entire livestock production process through Comprehensive Nutrient Management Plans.

The EU, through the Nitrates Directive, strictly limits manure application amounts, with Germany and the Netherlands using tax instruments to mandate nitrogen and phosphorus recovery rates, and Denmark demonstrating distinctive features in livestock regulation and ecological compensation. The Netherlands uses a management mechanism linking manure treatment with phosphate quotas. China has issued a series of environmental regulations, with the current legal system providing comprehensive regulation of pollution from large-scale livestock operations.

Where USR Process Delivers Superior Performance

Dedicated process for agricultural high-solids wastewater, primarily suitable for large-scale livestock manure, livestock soaking water, agricultural straw leachate, and livestock slaughterhouse high-solids wastewater. For high-suspended-solids, high-organics, high-impurity wastewater conditions, it is the core process for rural livestock pollution treatment and agricultural organic waste resource utilization. Suitable for township decentralized wastewater treatment and small to medium-sized agricultural enterprise wastewater treatment. Can serve as the primary process for large livestock base manure resource recovery, combining wastewater treatment with biogas recovery. Also suitable for various high-solids, easily clogged, difficult-to-treat organic wastewater pretreatment, with superior suitability in agricultural environmental applications compared to other anaerobic processes.

Cost-Effective O&M for Livestock Wastewater Treatment

O&M costs are relatively low with excellent input-output ratio-the highest cost-effectiveness among the five wastewater types. Core treatment units are primarily physical separation, anaerobic digestion, and ecological polishing-no high-end precision equipment or expensive chemicals. Equipment is simple with low failure rates and low maintenance costs. Anaerobic digestion produces stable biogas for plant heating and power generation, offsetting energy costs. Ecological treatment units have virtually no ongoing O&M costs. Only periodic cleaning of sedimentation tanks and polishing ponds is required, with low labor costs. Manure solids, sludge, and digestate can be sold as resources, further reducing net treatment costs.

Bangladesh Large-Scale Poultry Farm Manure Resource Recovery Project

Targeting local poultry farm manure resource recovery with daily treatment of 47 tons. Influent COD, BOD, SS as high as 50,000 mg/L, 25,000 mg/L, 50,000 mg/L-after CSTR + UASB anaerobic treatment, all three parameters reduced to below 200 mg/L, 100 mg/L, and 100 mg/L-effluent compliant with local environmental discharge standards. Project produces approximately 4,900 m³ biogas daily-each m³ biogas can generate 2 kWh of electricity, with daily power generation of 9,800 kWh-simultaneously achieving pollutant reduction and clean energy recovery. This is a benchmark project for livestock waste recycling in Southeast Asia.

Single and Double Membrane Roof for Biogas Storage Projects

Single and Double Membrane Roofs are proprietary airtight tank cover systems for anaerobic digestion and biogas storage projects, specifically developed for biogas collection and odor containment, representing a benchmark lightweight sealing solution for fermentation tanks. The single-layer membrane roof features a simple structure with economical cost, meeting basic biogas containment needs. The double-layer membrane roof consists of inner and outer corrosion-resistant membrane materials, with pressurized air in the interlayer forming rigid support, providing outstanding thermal insulation that reduces biogas condensate formation inside the tank, with enhanced wind and snow load resistance suitable for high-altitude and windy outdoor sites. The membrane material is specialized aging-resistant and biogas-slurry-corrosion-resistant PVDF membrane, which will not leak or degrade from long-term contact with biogas or hydrogen sulfide.

The flexible structure accommodates tank settlement and slight deformation without cracking or gas leakage. The lightweight design eliminates heavy steel support trusses, significantly reducing the load on the tank and foundation, saving construction costs. The roof integrates biogas outlets, safety pressure relief valves, and access channels, fully enabling closed gas collection for anaerobic fermentation tanks, recovering biogas for power generation and heating while blocking odor diffusion to meet environmental odor control requirements. It is widely used in large-scale livestock biogas projects, municipal sludge anaerobic digestion, and food waste fermentation projects, compatible with large-volume glass-fused-to-steel anaerobic tanks, with fast construction and simple maintenance requiring only periodic membrane seal integrity checks, offering significant overall engineering advantages.
