Why Choose Jiuwu Hi-Tech's Non-Woven Tubular Membrane for Pharmaceutical Wastewater Treatment?

Pharmaceutical industry wastewater is characterized by complex composition, high organic concentration, poor biodegradability, and frequent presence of biologically inhibitory substances, making it difficult to treat. Traditional processes often involve long treatment trains and insufficient stability, making it hard to consistently meet discharge standards. In a pharmaceutical wastewater MBR project in Changzhou, Jiangsu, the customer adopted a Jiuwu Hi-Tech non-woven tubular membrane system. The effluent quality met the required standards, with a daily treatment capacity of 300 m³, fully satisfying the customer's production discharge and reuse needs. The system features simple operation and low maintenance costs, delivering an efficient and reliable wastewater treatment solution for the customer.

TMBR Process: Synergistic Enhancement of Biological Treatment and Membrane Separation

The TMBR process is essentially an integration of the activated sludge process and membrane separation technology. Unlike the traditional activated sludge process, which relies on a secondary clarifier for solid-liquid separation, TMBR directly replaces the secondary clarifier with tubular ultrafiltration membrane modules. Sludge is taken directly from the aerobic tank into the tubular membrane system, achieving complete retention of sludge.

Core Process Flow: Pharmaceutical wastewater first enters the biological reaction tank, where, under the action of high-concentration activated sludge, pollutants such as organic matter and ammonia nitrogen are decomposed and transformed by a large number of microorganisms. Subsequently, the mixed liquor flows through the membrane module driven by a suction pump or pressure. The membrane acts as a "high-precision sieve," almost completely retaining activated sludge and macromolecular substances within the system, while allowing only water molecules and a small amount of small-molecular substances to pass through, forming purified effluent. This design offers multiple advantages:

Excellent Effluent Quality: The membrane separation precision is extremely high, effectively retaining bacteria, viruses, suspended solids, and colloids. The effluent turbidity is very low, enabling direct reuse or subsequent direct feed into an RO system, and reliably meeting stringent discharge standards.

Enhanced Biological Treatment Efficiency: The membrane retains all sludge within the system, maintaining a mixed liquor suspended solids (MLSS) concentration in the reaction tank that far exceeds that of traditional processes. This significantly increases the treatment load per unit tank volume, enhances the efficiency in degrading refractory organic compounds, and greatly improves the system's resistance to influent quality shocks.

Simplified Process Flow and Space Savings: By eliminating units such as the secondary clarifier and sand filters, the system features a compact footprint, reducing floor space requirements by approximately 30% to 50%.

Flexible and Controllable Operation: The sludge retention time (SRT) and hydraulic retention time (HRT) can be completely decoupled, facilitating the optimization of biological population growth conditions (e.g., nitrifying bacteria) and enabling more precise process control.
