“…This can be accomplished by using zero or near-zero liquid discharge (ZLD) procedures, which remove all the liquid waste from the system and produce solid waste (Ahirrao, 2014). Several physicochemical methods described later can be used on this principle, mainly thermal technologies (Liang et al 2021).…”

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.

The potential of increasing use of soft water in a circulating cooling water system can solve scaling problem and improve water conservation efficiency; however, it will bring corrosion to equipment and pipelines. In this study, isothioureaterminated pentaerythritol core dendrimers with 0−2 generations (PETA/4ITU-0G, PETA/8ITU-1G, and PETA/16ITU-2G) were developed as phosphorus-free corrosion inhibitors for carbon steel in soft water. The corrosion inhibition performance and mechanism of these dendrimers were studied by weight loss analysis and electrochemical measurements, surface morphology analysis, and molecular dynamics (MD) simulations. The results show that the corrosion inhibition efficiency isand they can spontaneously adsorb on the carbon steel surface to form a protective film. The sulfur and nitrogen atoms in the terminal isothiourea of the dendritic polymers bound with iron through physical and chemical processes. The performance of isothiourea-terminated pentaerythritol core dendrimers was better than that of isothiourea-terminated pentitol core dendrimers. PETA/8ITU-1G was the most cost-effective inhibitor and showed a better inhibition performance than PETA/4ITU-0G owing to its numerous terminal isothiourea groups in the molecular structure, which helps form a stronger protective film. The central core and number of terminated groups of dendrimers both play a role in the corrosion inhibition performance.

“…Environmental and human health have been put at risk by the discharge of industrial effluents. Reclamation of industrial effluents is gaining attention from the academic and industrial communities in order to create a win-win situation of water conservation and pollution control, with ZLD technologies that support this viewpoint rising (Liang Yinglin et al, 2021). This system uses cutting-edge scientific water treatment procedures to reduce the amount of liquid waste produced at the conclusion of your industrial process to zero, which is both effective and environmentally friendly.…”

Due to the increased demand for water over the past ten years, the recovery and recycling of wastewater has become a major trend. An ambitious wastewater management technique known as ZLD aims to completely remove all liquid wastes from leaving the plant or facility boundaries, with the bulk of water being recovered for reuse. This system uses cutting-edge scientific water treatment procedures to reduce the amount of liquid waste produced at the conclusion of your industrial process to zero, which is both effective and environmentally friendly. It is a procedure that benefits industrial, municipal and environmental groups because no effluent or discharge is generated. The treatment of industrial wastewater from two different companies was examined in this study over an 8-month period utilizing two ZLD treatment plants. Two ZLD processes were identical, but they were differed at two steps where batch evaporator and rotary kiln replaced each other with MEE and ATFD. In order to assess which process is reliable, two ZLD treatment plants were evaluated in terms of quantity, time, steam consumption, power consumption, and operational cost.
