Pharmaceutical wastewater

In biopharmaceutical production, the processes of fermentation broth concentration, extraction, separation, and purification often generate large quantities of dilute solutions containing salts or active ingredients. These materials are generally characterized by high heat sensitivity, significant batch-to-batch variability, and stringent hygiene requirements. Traditional evaporation methods, due to their high temperatures, high energy consumption, and susceptibility to cross-contamination, are ill-suited to the stringent standards of biopharmaceutical manufacturing.

In industries such as chemical, pharmaceutical, and environmental protection, the evaporation and concentration of sodium chloride-containing wastewater is a crucial step in achieving wastewater reduction and resource recovery. Triple-effect evaporation technology, with its mature reliability, moderate investment, and stable operation, has a broad application base in medium-scale treatment scenarios.

In the fields of fine chemicals, pesticide intermediates, and high-salinity wastewater treatment, the evaporation, concentration, and crystallization recovery of sodium chloride solution are crucial steps in achieving zero wastewater discharge and resource recycling. As one of the most common inorganic salts, the quality of sodium chloride's crystalline product directly impacts its downstream application value, while the energy consumption and stability of the evaporation system are related to the long-term operating costs of enterprises.

Sodium chloride, as a commonly used raw material salt, excipient, or reaction byproduct in pharmaceutical production, is widely present in wastewater from processes such as active pharmaceutical ingredient (API) synthesis, formulation production, and traditional Chinese medicine extraction and concentration. The recovery of sodium chloride from pharmaceutical wastewater not only involves resource reuse but also directly relates to environmental compliance and production cost control.

The "5th Sodium Chloride MVR Evaporator" is not just a piece of equipment, but a microcosm of the pharmaceutical industry's green transformation.

The "triple-effect countercurrent + TVR hot pressing" process is used to treat 5t/h of pharmaceutical high-salt wastewater.

This system validated the applicability of "triple-effect co-current + TVR + OSLO crystallization" in vitamin high-sulfate wastewater at a scale of 12.5t/h.

This unit validated the applicability of "triple-effect cross-flow + salt-nitrate separation" in pharmaceutical wastewater at a scale of 3t/h.
