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
