English Abstract

Among all biological processes for treatment of wastewater, biological filtration method is used as a secondary treatment technology for improving certain kinds of wastewaters.

The present work was aimed to illustrate several types of biofilters such as trickling filter (TF), rotating biological contactor (RBC), fixed bed filters, moving bed biofilm reactor (MBBR), and fluidized bed filters (FB).

An overview of each technique, operational parameters, typical standards, advantages and shortcomings of each method were revealed as well.

Moreover, applications suitability of various attached growth processes for the treatment of different wastewaters of other investigators were outlined.

Published works reported that applications of biofilm technology are efficient for treatment of weak wastewaters such as municipal wastewater with low strength rates.

In addition, biological filtration process particularly TFs are unproductive for treatment of strong wastewaters which contains high concentrations of organic matter, nitrogen compounds, heavy metals, phenols, grease and oil, and low biodegradability ratio.

Suggestions were outlined for enhancing efficiency of biological filtration process for treatment of high organic loading rate wastewaters.
