Bio filtration Pretreatment

Biofouling control is known to be a major problem in operating membrane systems.
A laboratory-scale Reverse Osmosis (RO) system was set up at a water reclamation plant to study the effectiveness of using Expanded Clay Aggregate (ECA®) as a bio-filter in the pretreatment process to control the biofouling.
The biological activity in the Reverse Osmosis system such as product, feed, and rejected streams was tested using the standard serial dilution technique.
Parameters such as permeate flow rate and differential pressure of the system were also discovered. Effects of bio-filter on Dissolved Organic Carbon and Assimilable Organic Carbon removals were carried out.
Bio-filtration, using Expanded Clay Aggregate (ECA®) as a bio-filter was discovered to be an ideal way of Dissolved organic carbon and Assimilable Organic Carbon removals.
It has removal efficiencies of 45 – 49% and 40 – 45% at a contact time of 25 - 30 minutes.
It was also discovered that using bio-filtration as a pretreatment minimized the rate of biofouling. This study showed the suitability and the importance of the bio-filter (ECA®) as a simple and economical way of biofouling control for Reverse Osmosis membrane.
