Metazachlor, once a common herbicide in farming, can harm water sources by polluting rivers, watercourses, and marine environments.
Its use is being banned across the world so effective water treatments are extremely important to protect the environment. We can help using our Nyex Rosalox system.
Metazachlor is used to control weed growth in crops, trees and shrubs. BASF and Adama joined forces under the MTZ Matters brand to prevent water contamination in relation to land run-off. Pesticide pollution has meant that substances like metazachlor are now being banned from entering the environment.
The Nyex Rosalox™ system is very energy-efficient, reducing operational costs and contributing to sustainable water treatment practice in metazachlor water purification. Its modular design allows for scalability, making it suitable for various water treatment applications, from small-scale agriculture and aquaculture operations to large agrochemical manufacturing facilities.

Several metazachlor removal systems are currently in use for water purification. Each method has its advantages and limitations, making it essential to carefully consider the specific requirements of the treatment scenario.
Here are some of the commonly employed techniques:
Ozone treatment is a promising method for removing metazachlor from water due to its strong oxidation potential. When ozone enters water, it reacts with metazachlor, breaking it down into simpler and less harmful substances. This process is advantageous as it eliminates the need for chemical additives, reducing the formation of harmful byproducts.
However, handling ozone requires caution, as it is a toxic gas. Specialized equipment and safety measures are necessary to prevent exposure to ozone. Additionally, the cost of ozone generation and potential health and safety concerns can be limiting factors for small-scale applications.
In summary, ozone treatment is effective in breaking down metazachlor molecules into harmless byproducts. However, the handling and disposal of toxic chemicals like ozone pose challenges.
Many organisations use GAC in water treatment because it has exceptional adsorption capabilities. When water containing metazachlor passes through a GAC bed, the herbicide molecules are attracted to the carbon surface, effectively removing them from the water. GAC-based systems can be effective in treating large volumes of water and are relatively simple to operate.
However, GAC has a limited capacity to adsorb pollutants, and over time, the carbon bed becomes saturated. This necessitates the replacement and proper disposal of spent carbon, which can be a logistical challenge and adds to operational costs.
So because the spent carbon contains the accumulated pollutants, it requires secondary disposal, and this is really quite bad for our environment.

Among the various methods available for herbicide removal, the Nyex Rosalox™ system by Arvia Technology stands out as the most effective water treatment for metazachlor contamination. This innovative system combines adsorption with an electrochemical oxidation process, providing a comprehensive and sustainable approach to water purification.
The Rosalox™ system utilizes a unique adsorbent material – Nyex™. It is specially designed to target and remove organics like metazachlor from water. The adsorbent is highly effective and is regenerated in situ, extending its operational lifespan and reducing waste generation.
The electrochemical oxidation part of the process complements adsorption by breaking down adsorbed pollutants into non-harmful substances – essentially water and gas. This two-step approach ensures a thorough and reliable removal of metazachlor and other contaminants, resulting in cleaner water with minimal ecological impact.
