Water Purification Process: How Your Water Gets Purified ...

2020-7-20 · Coagulation and Flocculation: This is often the first step in the purification process. This is where chemicals with a positive charge are added to the water in order to neutralize the negative charge of dirt and other dissolved particles in the water. As this happens, the particles bind the chemicals and form even larger particles, called floc.

A novel separation and purification process for 1,3 ...

2006-3-1 · Li et al. developed the 1,3-propanediol-purification process based on the ZSM-5 zeolite membrane, which still had some drawbacks such as a low flux and selectivity. Malinowski and Broekhuis et al. reported the recovery of 1,3-propanediol using an extraction method. In this method, the direct extraction of 1,3-propanediol was almost impossible ...
