Ultra-filtration Membrane Module for Pure Water Purification with PVDF material
Ultrafiltration is a specialized membrane filtration technology that enhances pressure-mediated suspension of pathogenic and solid waste from waste mixture. The product produced after ultrafiltration is highly pure and free of any pathogenic waste. Most of the characteristics of ultrafiltration are quite similar to membrane-based filtration as ultrafiltration strategy is aligned with semipermeable membrane utilization. The membranes used for ultrafiltration process can be of various types. For instance, micellar enhanced membrane can filtrate complex chemicals using pressure-driven ultrafiltration process. Both micellar and surfactant-based filters can remove heavy metals from waste using ultrafiltration strategies (Tortora et al., 2016; Huang et al., 1994). Besides, artificially produced chemical membranes are also found useful to isolate a wide range of pollutants using ultrafiltration strategies . Thus, as per the users demand and necessity, ultrafiltration membranes are designed to separate specific types of pollutants from waste materials using a pressure-driven process.
