The treatment of shale gas fracturing flowback fluid wastewater is a complex and critical process aimed at reducing environmental pollution, protecting water resources and realizing the resource utilization of wastewater.In the process of shale gas fracturing flowback fluid treatment, MVR evaporation technology introduces wastewater into the evaporator and uses heat energy to evaporate the water in the wastewater, thereby reducing the amount of wastewater.

To meet increasingly stringent environmental regulations and emission standards, petrochemical enterprises are actively seeking advanced wastewater treatment solutions that enable reduction, reuse, and recycling of industrial effluents. One of the most critical goals in this domain is achieving Zero Liquid Discharge (ZLD)—a process that ensures complete recovery of usable water and solid separation of all dissolved contaminants.

A comparison between Low-Temperature Evaporator (LTE), Mechanical Vapor Recompression (MVR), and Multiple-Effect Evaporator (MEE)

In the fields of industrial wastewater treatment, high-salt waste liquid concentration, biopharmaceutical purification, etc., low-temperature evaporation technology has gradually become the mainstream choice of the industry due to its high efficiency, energy saving and environmentally friendly characteristics. This article will give you a comprehensive understanding of the current mainstream low-temperature evaporation process from the perspectives of technical principles, core processes, and applicable scenarios.

Most methods for treating pesticide wastewater use physical and chemical methods, including adsorption, extraction, hydrolysis, oxidation, membrane separation, etc. Among them, thermal technology, as one of the supporting technologies for zero discharge of wastewater, mainly includes membrane distillation (MD), flash evaporation (MSF) technology, multi-effect evaporation (MED) technology, mechanical compression evaporation (MVR) and other technologies. Thermal method is to use heating and concentration to remove the light components of the solution in the form of fractions, and the heavy components are concentrated to increase the concentration of the solution.

Zinc-nickel alloy wastewater mainly contains harmful substances such as nickel, zinc, ammonia nitrogen, COD, etc. It has complex components and many complexes. Therefore, to treat this kind of wastewater, the complexing agent must be removed first, otherwise the heavy metal ions cannot be precipitated.

Through the case study of fluorine-containing high-salt mother liquor wastewater treatment in a large fine chemical enterprise in my country, the process of high-salt mother liquor wastewater treatment in fine chemical enterprises is explained.

This article will introduce in detail the entire process of wastewater treatment in six major industries, including fine chemicals, coal chemicals, petrochemicals, surface treatment, hazardous waste, mechanical processing and other industries, to help readers fully understand the wastewater disposal process of various industries.

In the field of environmental protection, the effective treatment of leachate has always been a very challenging task. Winsonda has achieved remarkable results in leachate treatment projects with its advanced technology and professional solutions. Two typical cases will be introduced in detail below.

At a time when the environmental protection industry is booming, there is a company that focuses on the comprehensive utilization of hazardous waste (hereinafter referred to as "the company"), which is constantly exploring and moving forward in the field of environmental services. With professional technology and perfect disposal lines, it is committed to contributing to environmental protection. However, in terms of wastewater treatment, the company has also faced many challenges.

In response to the current difficulties in oil and gas field wastewater treatment and to overcome the defects and shortcomings of traditional water treatment technology, Winsonda has continued to innovate and was the first to launch a low-temperature evaporation crystallization device, which has technical advantages such as short process flow, high stability, low treatment cost, strong anti-scaling performance, and resource-based disposal.

Common treatment methods for zero discharge of high-salinity wastewater include membrane separation, MVR and multi-effect evaporation technologies. Through these technologies, the salt concentration in the wastewater can be reduced so that the wastewater meets the environmental discharge standards.
