New report on the formation of sludge and the composition of biofilm in wastewater drain fields

Published: 27 November 2019

The most common methods for on-site treatment of domestic wastewater are soil-based methods such as drainfields. In previous municipal projects, the occurrence of sludge in different parts of such treatment facilities has been observed.

The aim of this study was to investigate possible causes of sludge formation in on-site drain fields. Samples were taken from the sand below the distribution pipe and studied using NGS (Next-Generation Sequencing). However, the bacterial composition did not significantly differ across the investigated infiltration beds. In all samples, Betaproteobacteria, Gammaproteobacteria, Alphaproteobacteria, Sphingobacterii, Actinobacteria and Deltaproteobacteria dominated.
