- Abstract:
- Membrane scaling is one of the important limitations of membrane treatment process in waterworks, resulting in the decline of membrane flux and the shortening of membrane lifespan. The addition of antiscalants is a convenient and effective method to prevent membrane scaling. The scale inhibition mechanism, the various types of antiscalants available and their respective applications in membrane treatment processes are reviewed respectively. The structures, characteristics and synthesis methods of phosphorus antiscalants, polymeric antiscalants and environment-friendly antiscalants are also summarized. It further elucidates the application forms and scale inhibition performance of these antiscalants in membrane treatment processes within waterworks. Additionally, it identifies existing challenges in the application of antiscalants and offers prospects for their future development and utilization.
