“…Some materials bind irreversibly on the resin and continuously reduce the ion exchange capacity of the resin (Simandi 2011). Ma et al (2021b) demonstrated the effectiveness of magnesium and calcium ion removal from chemical wastewater with the combination of coagulation and ion exchange. Reclaimed water can be recycled with their integrated process, thus achieving near-zero liquid discharge.…”

In the chemical industry, a typical problem is the appropriate treatment of the process wastewaters. The biological treatment cannot be usually applied because of the high content of organochemical compounds. However, phsycicochemical methods can significantly contribute to the proper treatment of the process wastewater and usually also allows the recovery of the polluting materials. This phenomenon opens the application area of physicochemical methods for the treatment of process wastewater and can contribute not only to the aims of the circular economy but also to the zero liquid discharge. Besides literature studies, authors’ own results and innovations have been also presented. The treatment strategy for pharmaceutical process wastewater is reviewed in detail, which also serves to point out that hybrid methods can be usually efficient to solve the primary goal–maximum recovery and reuse of polluting materials.

“…Thermal-based techniques can treat a broader range of wastewater with less stringent pretreatments, and the concentrated liquid can be recycled to be evaporated after producing solid material from its crystallizer. Membrane-based and thermal-based processes could be integrated into a saline organic wastewater treatment system to boost the efficiency …”

Mechanical vapor recompression (MVR) is an energy-saving evaporation and crystallization process for saline wastewater treatments; however, its proper application depends on many conditions. We performed evaporation experiments on 57 wastewater samples, with ten parameters generated for each sample, then performed decision tree models to determine if the samples were directly suitable for mechanical vapor recompression. Our results indicated that the decision tree analysis successfully classified our samples, and exergy analysis demonstrated MVR had great energy saving potential.

“…It has been estimated that 4.7 billion tons of wastewater are generated annually in the coal industry, with the numbers projected to increase further. 1 Meanwhile, coal chemical wastewater has a complex water quality and composition, and contains large quantities of phenolic pollutants. Their high solubility in water and carcinogenicity make them the most harmful class of pollutants.…”
