Removal of disinfection by-product precursors by ion exchange resins

Removal of disinfection by-product precursors by coagulation and an innovative suspended ion exchange process.

This investigation aimed to compare the disinfection by-product formation potentials (DBPFPs) of three UK surface waters (1 upland reservoir and 2 lowland rivers) with differing characteristics treated by (a) a full scale conventional process and (b) pilot scale processes using a novel suspended ion exchange (SIX) process and inline coagulation (ILCA) followed by ceramic membrane filtration (CM...

Removal of Disinfection By-product Precursors Using Hybrid Coagulation–Ceramic Membrane Systems

2016 © American Water Works Association JOURNAL AWWA OCTOBER 2016 | 108:10 Microfiltration (MF) membranes are low-pressure membranes that generally have pore sizes in the range of 1 to 0.1 μm. They can effectively reject bacteria, protozoa, and colloidal particles by size exclusion. The physical rejection of viruses and the dissolved fraction of natural organic matter (NOM) by MF (0.1 μm nomina...

Disinfection by-product minimisation by organic and inorganic precursor removal

[Ion exchange resins].

Ion exchange resins have been used to help formulate pharmaceuticals since the late 1950's. During that time they have proved to be safe and effective excipients and are now used in many commercial formulations throughout the world. In this article we will look at some of the common problems faced by formulators and how using ion exchange resins may be able to solve them. Ion exchange resins ar...
