Introduction
Due to its high pollutant concentration, high inorganic salt content, high conductivity, and poor biodegradability, membrane concentrate presents significant challenges in treatment. Improper treatment of membrane concentrate can lead to secondary pollution, resulting in environmental damage that may be irreversible and immeasurable.

Process
To address the challenge of treating wastewater from phosphoric acid iron and trivalent precursor materials, WSD Environmental Protection has developed a low-temperature evaporative crystallizer, which reduces energy consumption by over 50% and lowers operating costs. When wastewater from phosphoric acid iron and trivalent precursor materials undergoes pre-filtration and enters the low-temperature vacuum evaporative crystallizer, it evaporates under vacuum and low-temperature conditions. The water vapor condenses into distilled water during the vacuum extraction process, which is collected in a clean water tank. The remaining residue in the distillation kettle is collected in drums for further processing. This process significantly reduces or even eliminates harmful chemicals and heavy metals in the wastewater. The evaporation rate of the equipment can reach over 60%. Through pre- and post-treatment processes, the effluent is clear and transparent, meeting biochemical water quality standards, allowing for water reuse or discharge to meet standards. Residues are automatically discharged and transported for disposal.
