Professional China WWTP Project Contractor: Advanced EPC & Turnkey Wastewater Solutions

As China’s environmental regulations under the "14th Five-Year Plan" drive a national shift toward (pollution reduction and carbon synergy), industrial and municipal entities require a specialized WWTP (Wastewater Treatment Plant) project contractor capable of delivering high-efficiency, compliant, and sustainable infrastructure.

Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is a premier high-tech environmental engineering contractor. With over 30 years of history, we provide integrated EPC (Engineering, Procurement, and Construction) services and proprietary Process Packages that address the most challenging water treatment requirements across China and globally.

 

Comprehensive Wastewater Treatment Expertise & Technical Scope

Center Enamel is recognized as a "one-stop" solution provider for diverse wastewater challenges. We bridge the gap between advanced biological process engineering and robust mechanical manufacturing:

  • Industrial Wastewater: Specialized treatment for Textile, Palm Oil (POME), Food Processing, Brewing/Distillery, Starch, and Pharmaceutical sectors.
  • Municipal Sewage: Full-scale urban and industrial park WWTP construction and upgrades.
  • Livestock Wastewater: Energy-ecological solutions for high-capacity pig and poultry farms.
  • Food/Kitchen Waste: Advanced anaerobic digestion systems for waste-to-energy conversion.

Proprietary Process Packages

The core of our success as a contractor lies in our mastery of high-rate anaerobic and aerobic process sections, ensuring stable effluent quality and high removal efficiencies:

  • IC (Internal Circulation Reactor): A compact, high-rise reactor ideal for high-load industrial effluent (e.g., Brewing and Starch).
  • UASB (Upflow Anaerobic Sludge Blanket): A global standard for efficient organic removal and biogas recovery.
  • CSTR (Continuous Stirred Tank Reactor): Optimized for high-concentration organic slurries, including livestock manure and kitchen waste.
  • EGSB & USR: Specialized reactors designed for granular sludge management and high-solids applications.

Vertically Integrated Equipment Supply

We ensure the long-term operational resilience of our WWTP projects by manufacturing the critical mechanical systems in-house:

  • Storage Solutions: Our signature Glass-Fused-to-Steel (GFS) tanks provide superior corrosion resistance (pH 1-14) and meet AWWA D103-09 and NSF/ANSI 61 standards.
  • Mechanical Integration: Including high-efficiency mixing systems, specialized tank covers/roofs for odor control, sludge treatment systems, and integrated heating units.
  • Ancillary Components: Precision pumps, piping, valves, and industrial boilers.
