Center Enamel Provides IC Technology for Industrial Wastewater
Pretreatment
Industrial wastewater treatment is a critical challenge due to its
high organic load, complex composition, and strict environmental
regulations. To meet these demands, Shijiazhuang Zhengzhong
Technology Co., Ltd (Center Enamel) provides advanced Internal
Circulation (IC) Reactor technology, a highly efficient anaerobic
solution for industrial wastewater pretreatment.
With decades of expertise in anaerobic digestion technology, Center
Enamel delivers cost-effective, energy-efficient, and
environmentally friendly solutions that help industries comply with
discharge standards while recovering biogas energy for sustainable
operations.
Challenges in Industrial Wastewater Pretreatment
Industrial wastewater varies significantly depending on the
industry, often containing:
High levels of Biological Oxygen Demand (BOD) and Chemical Oxygen
Demand (COD) – Leading to oxygen depletion in receiving waters
Complex organic compounds – Including fats, oils, proteins, and
starches from food processing, petrochemicals, and paper mills
Toxic or inhibitory substances – Such as heavy metals, sulfates,
and nitrogen compounds
High temperature and fluctuating pH levels – Affecting microbial
stability in biological treatment systems
To handle these challenges efficiently, IC technology has emerged
as an ideal anaerobic pretreatment solution, particularly for
high-strength wastewater with COD concentrations exceeding 5,000
mg/L.
What is IC (Internal Circulation) Technology?
The Internal Circulation (IC) Reactor is an advanced high-rate
anaerobic digestion system designed to maximize the breakdown of
organic pollutants while producing biogas. The IC reactor is widely
used for treating industrial wastewater with high organic content,
making it an ideal pretreatment technology before secondary aerobic
treatment.
How IC Technology Works for Industrial Wastewater Pretreatment
Wastewater Inflow & Pre-Treatment
Removal of large solids, grease, and suspended particles
Equalization and pH adjustment to ensure stable anaerobic
conditions
IC Reactor Anaerobic Digestion
Wastewater enters the two-stage reactor, where microbial
communities degrade organic matter
Upflow liquid circulation enhances contact between wastewater and
anaerobic sludge, increasing efficiency
Biogas (methane & carbon dioxide) is continuously produced and
collected
Biogas Recovery & Utilization
Biogas is captured and used for electricity generation, heating, or
steam production
Reduces reliance on fossil fuels, lowering operational costs
Effluent Treatment & Discharge
Pre-treated wastewater undergoes further aerobic treatment,
nutrient removal, and polishing
Ensures compliance with environmental discharge regulations
Advantages of IC Technology for Industrial Wastewater Pretreatment
High COD & BOD Removal Efficiency
Reduces organic pollution loads by 85–95%, enabling effective
secondary treatment
Compact Footprint & High Loading Capacity
Requires less space compared to conventional anaerobic reactors
Handles high-strength wastewater (>10,000 mg/L COD) efficiently
Energy Recovery through Biogas Production
Converts wastewater pollutants into valuable biogas, reducing
energy costs
Stable Performance & Low Sludge Generation
Internal circulation system ensures high microbial activity and low
sludge production
Cost-Effective & Environmentally Sustainable
Minimizes chemical consumption, reducing operational costs and
carbon footprint
