A thin layer of a concentrated polymer solution is immersed into a bath of nonsolvent to produce immersion precipitation. The polymer solution becomes unstable by the interchange of solvent from the polymer solution and nonsolvent from the coagulation bath.
A polymer rich phase and a polymer lean phase are the products of liquid-liquid phase separation. Inside a matrix that was made by the polymer rich phase, which also forms the membrane, the polymer lean phase creates pores. The method that is employed the most frequently to create polymeric membranes is immersion precipitation.
The global immersion membrane market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The immersed ZeeWeed 500 membrane from SUEZ is made especially for hard-to-treat water sources. The strongest ZeeWeed membrane from SUEZ can generate water with exceptionally high purity and low silt density, which is useful for drinking water, wastewater treatment, water reuse, and industrial applications.
The compact NEOSEPTM method from Veolia Water Technologies combines immersed membrane filtration with activated sludge treatment. Water produced by NEOSEPTM technology is of very high quality and is appropriate for reuse, irrigation, or discharge.
The Eco-MBR is a membrane bioreactor that was created by Mitsubishi Electric that uses ozonated water to clean the membrane filter.
In comparison to typical membrane bioreactors, the device achieves high-speed filtration with roughly twice the flow rate of permeate per unit of membrane surface area, halving the number of membrane filters needed, enhancing compactness, and reducing energy usage by 25%.
