“…Indirect (pipe) freeze crystallization (IFC) principles are based on the basics of freez crystallization but with a distinctive indirect approach. As wastewater undergoes con trolled freezing, ice crystals form, acting as carriers for targeted contaminants and valua ble resources [23,81]. The indirect nature of IFC involves the subsequent separation o these ice crystals from the liquid phase, offering an efficient method of resource recovery These principles aim at exploiting the differential solubilities of various components i wastewater at freezing temperatures.…”

This paper explores the efficiency and potential of indirect freeze crystallization (IFC) as a valuable resource-recovery technology in wastewater treatment, particularly focusing on acid mine water and hazardous material wastewater-treatment plants. Wastewater treatment poses challenges to recovering valuable resources effectively, enforcing the need for sustainable and resource-efficient technologies like freeze crystallization. Through a thorough examination of IFC principles and mechanisms, this paper aims to highlight its applications, advantages, and limitations. The investigation includes a comprehensive literature review and detailed methodology from one of the IFC pilot plants, as well as a critical analysis of the environmental and economic implications of IFC. By addressing scaling challenges in reverse osmosis and proposing an environmentally friendly brine disposal method through IFC, this paper contributes to reducing the environmental footprint associated with wastewater treatment. Additionally, this paper highlights the importance of extracting valuable resources from highly saline water and emphasises the potential economic and environmental benefits of resource recovery, particularly focusing on the promising technology of IFC.

“…The process of malathion "captured" by ice is influenced by both the ice growth rate and the malathion diffusion rate. When the ice growth rate is greater than the diffusion rate of malathion, malathion is not able to diffuse and is "captured" by the ice [ 50 ]. The freezing temperature is a major factor in the growth rate of ice.…”

The effect of malathion in ice is a poorly researched area, and ice is an important habitat for organisms at the base of the food web. This study presents laboratory-controlled experiments designed to investigate the migration rule of malathion during lake freezing. Concentrations of malathion were determined in samples of melted ice and in under-ice water. The effects of the initial sample concentration, freezing ratio, and freezing temperature on the distribution of malathion in the ice–water system were investigated. The concentration effect and migration capacity of malathion during freezing was characterized by the concentration rate and distribution coefficient. The results showed that the formation of ice led to the concentration of malathion appearing as follows: concentration in under-ice water > concentration in raw water > concentration in ice. This implied that malathion tended to migrate from the ice to the under-ice water during the freezing process. The increase in the initial malathion concentration, freezing ratio, and freezing temperature caused a more pronounced repulsion of the malathion by the ice and increased the migration to the under-ice water. When the solution of malathion with an initial concentration of 50 μg/L was frozen at –9 °C and the freezing ratio reached 60%, the concentration of malathion in the under-ice water was concentrated to 2.34 times the initial concentration. The migration of malathion to under-ice water during freezing may pose a potential threat to under-ice ecology; therefore, the environmental quality and impact of under-ice water in icebound lakes needs to be given more attention.

“…It uses a two-by-two comparison of attributes to calculate weights, integrates the opinions of several experts, eliminates some obviously unreasonable data, and has a certain degree of objectivity ( Beskese and Bozbura, 2014 ). The main objective weighting methods are the entropy method ( Sun et al, 2017 ), the coefficient of variation method ( Qi et al, 2021 ) and the correlation coefficient method ( Abdelmoaty et al, 2021 ). When more complete sample data is available, objective weighting can be used and the results can be modified by cross-sectional comparisons between indicators.…”

At present, China’s cross-border e-commerce has ushered in a golden period of development. When developing cross-border e-commerce, enterprises should first assess the market climate of the target country and reasonably select the target country. Based on the PESTEL theory, an evaluation index system is established for China’s cross-border e-commerce overseas strategic climate. Taking “One Belt, One Road” as the opportunity and background, the overseas strategic climate of cross-border e-commerce in 62 countries along the “One Belt, One Road” is selected as the research object, and the Decision Tree and Adaptive Boosting classification methods in machine learning are applied to train and predict the established index system. Finally an overall picture of the overseas strategic climate of the 62 countries is obtained. The results are compared and analysed in depth to identify the most suitable countries for cross-border e-merchants and to provide reference for cross-border e-merchants investors.
