METHOD FOR CONTROLLING pH IN A DIFFUSIOPHORETIC WATER FILTER AND DIFFUSIOPHORETIC WATER FILTER WITH pH CONTROL

摘要

A method of filtering a colloid in a diffusiophoretic water filter including adjusting the pH value of the colloid by adding at least one of an acid or a base upstream of the diffusiophoretic water filter and filtering the colloid in the diffusiophoretic water filter to produce a waste stream and a filtrate is provided.
