In the context of increasingly serious climate change and environmental pollution. Advanced wastewater treatment technologies are being researched and widely applied to improve water quality. At the same time, improve investment efficiency and reduce operating costs. 2024 witnessed the remarkable development of many new technologies in wastewater treatment. Enterprises and localities meet green standards in the circular economy and increasingly high environmental standards. Help optimize the efficiency of water resource use.

This article will introduce the most advanced wastewater treatment methods today, focusing on improvements in technology, treatment efficiency and the ability to save operating costs.

1. Advanced Membrane Technologies

Membrane technology is one of the most advanced solutions in wastewater treatment. Especially when high quality water after treatment is required. In 2024, improvements in membrane technology have increased efficiency and processing capacity. Helping to reduce investment and operating costs.

• Nanofiltration and Ultrafiltration: These membranes are improved to treat wastewater with smaller particle sizes. This removes impurities, microorganisms, and even heavy metals. These membranes also have better filtration capacity at low pressure, which helps reduce energy consumption.
• Reverse Osmosis (RO) membrane): RO technology has been upgraded with membranes that are more durable and resistant to clogging. This allows the system to operate continuously, minimizing maintenance time and operating costs.

Nhờ các cải tiến trong vật liệu và cấu trúc màng, công nghệ màng lọc tiên tiến đã trở thành lựa chọn hàng đầu cho các ngành công nghiệp. Như trong: thực phẩm, dược phẩm, và sản xuất điện tử, các ngành yêu cầu chất lượng nước sau xử lý cao.

2. Cold Plasma Technology

Cold plasma is one of the latest technologies applied in wastewater treatment. Different from traditional methods such as biological or chemical treatment. Cold plasma technology uses gas ionization to create free radicals capable of destroying organic pollutants and microorganisms in wastewater.

• High efficiency: Cold plasma can effectively treat organic compounds that are difficult to decompose such as pesticides, pharmaceuticals and persistent chemicals. It is more effective than other traditional methods.
• Energy saving: This technology operates at low temperatures and does not require the use of chemicals. It helps to save operating costs and minimize environmental impact.

Cold plasma is gradually becoming a popular wastewater treatment method in industries with difficult-to-treat wastewater and hazardous wastewater. Highly effective in killing bacteria and toxic components for wastewater reuse processes.

3. Biological Wastewater Treatment (Bioaugmentation and Advanced Bioreactors)

Microbial wastewater treatment technology is no longer a new concept. But in 2024, this method has been upgraded with significant improvements in performance and wide applicability.

• Bioaugmentation: a method of adding special strains of microorganisms to the wastewater treatment system. To enhance the ability to decompose complex organic substances in wastewater. Bioaugmentation is especially effective in the chemical, pharmaceutical and food industries.
• Membrane Bioreactor (MBR): MBR technology combines biological treatment and membrane filtration. Helps to remove maximum pollutants and harmful microorganisms in wastewater. Advanced MBR systems in 2024 are designed with high automation capabilities. To minimize human intervention and optimize the treatment process.

Thanks to the development of special microorganisms and advanced control systems. Microbial wastewater treatment is becoming a popular method for businesses. With the desire to optimize the treatment process and reduce operating costs.

4. Electrochemical Water Treatment Technology

Electrochemical wastewater treatment is a new trend in 2024, with the ability to effectively treat difficult-to-treat wastewater such as wastewater containing heavy metals, grease and complex chemical compounds.

• Electrocoagulation: This method uses electric current to generate metal ions. This helps to coagulate impurities in wastewater and easily remove them. Electrolysis can effectively treat wastewater containing heavy metals and stable organic substances
• Electrooxidation: This method uses electricity to generate strong oxidants such as hydroxyl and ozone in wastewater. To decompose organic pollutants and kill microorganisms. This method is very effective in treating wastewater containing difficult-to-decompose organic substances and drug-resistant bacteria.

Electrochemical treatment technology is increasingly popular. Thanks to its flexible processing capabilities and low operating costs compared to traditional methods.

5. Reusing Wastewater Using Forward Osmosis Technology

Multi-step osmosis is not only an advanced wastewater recycling technology but also helps to reduce energy consumption. This is a newly developed technology that combines natural osmosis and filtration steps to recover clean water from wastewater.

• Energy saving: This technology uses natural osmotic pressure to separate water from impurities. There is no need to use high pressure pumps as in RO technology, which helps reduce energy consumption.
  Water reuse: Wastewater after being treated by multi-step osmosis can be reused. Applicable to production or irrigation activities, helping businesses save clean water costs and protect water resources.

Multi-step osmosis is being tested and applied in industries with large amounts of wastewater. Especially in heavy industries and agricultural production.

6. Do not discharge ZLD liquid with evaporation technology

Evaporation technology is a method of converting water from liquid to vapor to separate pollutants from wastewater. This technology is considered an advanced solution in treating wastewater with high concentrations of pollutants. Highly effective for wastewater that is difficult to treat with traditional methods such as biological or chemical.

Conclusion

The year 2024 marks the strong development of advanced wastewater treatment technologies. With many new solutions, helping to improve water quality and optimize operating costs. From membrane filtration technology, cold plasma, evaporation, to multi-step osmosis. Helping businesses and localities have many options to improve wastewater treatment efficiency, comply with environmental regulations and protect water resources.
