The Role and Development Trend of Water Treatment Agents

Water treatment is a crucial aspect of research on new water treatment agents. The emergence of new water treatment technologies will expand the production and application scope of these agents, significantly promoting the development of industrial water chemical treatment.

Research on industrial water treatment agents primarily includes:
Corrosion inhibitor-scaling agents
Flocculation-corrosion inhibitors
Flocculation-bactericides
Flocculation-bactericide-corrosion inhibitors
Flocculation-corrosion inhibitor-scaling agents
The standard for water treatment agents refers to the changes in key factors such as the interaction between corrosion inhibitor molecules, the interaction between corrosion inhibitor molecules and interfaces, and spatial geometric positions at the molecular level due to the interaction of different corrosion inhibitor molecular characteristic groups on the metal surface. This makes the adsorption layer denser, increasing and improving the protective performance of the corrosion-resistant film. Water treatment agents can enhance corrosion inhibition efficiency, expand the scope of use of corrosion inhibitors, make them suitable for harsher and broader environments, and reduce the cost of agents. This is a significant part of the theoretical research on corrosion inhibitors in water treatment agents.

To establish a molecular model of a water treatment agent with synergistic effects, it is necessary to consider the effects of different structural central atomic characteristics and the forces between the agents and the interface. This requires the introduction of more quantum parameters and calculations. Although challenging, this research has great theoretical significance and practical value, especially for designing specific molecules of water treatment agents that affect the chemical and electrochemical processes on the metal surface. Thus, it represents an important direction for future research on the mechanisms of water treatment agents.

Development of Green Water Treatment Agents
In the green development of water treatment, the focus is on non-toxic, harmless, and biodegradable agents. A typical green water treatment agent is the dispersed scale inhibitor polyaspartic acid (PASP), developed both domestically and internationally in recent years. PASP is a synthetic biopolymer with good biocompatibility and biodegradability. Toxicological studies have shown that PASP is non-toxic, non-sensitive, and non-mutational.

Development of Cost-effective Water Treatment Agents
Currently, new high-performance water treatment agents are generally expensive. We can develop high-performance products by finding cheap and readily available raw materials or by strengthening research on compounding technology. This involves adding inexpensive auxiliary agents to reduce the actual amount of agents needed while maintaining water purification efficiency, thus reducing costs.
