Industry Pain Points in High-Suspended-Solids Wastewater Treatment
Coal-containing wastewater generated in coal yard spraying, coal conveying system washing, and other processes in thermal power plants has a suspended solids concentration as high as 2000–5000 mg/L, with particle diameters generally less than 0.1 mm. This type of wastewater is extremely difficult to treat in terms of turbidity and chroma. Traditional processes such as coagulation sedimentation or electrocoagulation face four major challenges: incomplete collection systems, inadequate primary sedimentation tank design, equipment corrosion and clogging, and insufficient treatment capacity during the rainy season. Especially in water-scarce regions such as Southeast Asia and the Middle East, these issues directly impact power plant compliance with discharge standards and cost control-and ceramic membrane for oil water separation technology is becoming a key solution to break through these challenges.
1. Efficient Nanoscale Separation: Precise Interception of Suspended Pollutants
The core challenge of coal-containing wastewater is the difficulty in settling ultrafine coal powder (particle size < 0.1 mm). Tubular ceramic membrane, with its precise pore size of 0.01–0.1 μm, can efficiently intercept nanoscale particles, reducing the effluent suspended solids to a stable 10–20 mg/L. Compared to traditional processes, it does not rely on chemical flocculants, avoiding secondary pollution caused by reagent failure.

2. Extreme Environment Tolerance: Zero Corrosion in Acid-Alkali and High-Temperature Conditions
Coal wastewater often contains acidic coal gangue leachates or alkaline cleaning agents. Zirconia membrane has chemical stability far exceeding that of organic membranes, withstanding strongly corrosive environments at pH 0–14 , short-term temperature resistance up to 130°C, and recommended long-term operation at ≤80°C. It can directly treat high-temperature drainage from thermal power plants, eliminating the need for cooling stages.
3. Anti-Fouling and Low Energy Consumption: Ensuring Stable Operation During Rainy Seasons
Traditional microporous ceramic filter media is easily clogged by coal powder, requiring frequent backwashing. In contrast, the smooth surface of tubular ceramic membrane alumina membranes employs a "cross-flow filtration" design, where coal powder is flushed away from the membrane surface by the water flow, reducing clogging risk. Combined with Taihe Environmental's patented pulse backflushing technology , the cleaning cycle is greatly extended.
Economic Comparison: Reduces energy consumption by 30% compared to traditional processes, with significantly improved treatment capacity during rainy seasons.
4. Modular Integration: Flexible Solution for Old Plant Retrofitting
Power plants in the Middle East and Southeast Asia commonly face space constraints. The ceramic membrane system occupies only one-third the area of inclined plate sedimentation processes and supports stacked modular design. Taihe Environmental ceramic ultrafiltration membrane can be seamlessly integrated into existing coagulation tanks without rebuilding infrastructure.
Application Scenarios: Adapts to complex scenarios such as mine drainage, coal washing wastewater, and coal yard rainwater reuse, with recycled water quality meeting industrial cooling standards.
5. Full Membrane Process Resource Recovery: Core Technology for Zero Emission Strategy
In response to the "zero liquid discharge" policy in the Middle East, Taihe Environmental innovates a Ceramic-based membranes for water and wastewater treatment process chain: ceramic membrane pretreatment → RO concentration → evaporation crystallization, achieving coal powder recovery and freshwater regeneration.
Conclusion: Technology Driving the Future of Sustainable Water Management
Tubular ceramic membrane, with its high-efficiency separation, extreme tolerance, and low maintenance, is reshaping the paradigm of coal-containing wastewater treatment. As one of the few domestic companies mastering the entire ceramic membrane industry chain technology, Taihe Environmental's solutions have served multiple projects. Its oil-resistance properties extend to the ceramic membrane for oil water separation field, providing new pathways for refining and oilfield wastewater treatment.
