Organic matter removal in bio-filters to achieve biologically stable water downstream of the process
Organic removal contaminants reclamation has increased over the past years as it has many advantages over other treatments. Product water from water treatment plants can be chemically complex resulting in physical and biological changes during transportation in the distribution systems. The general aim of this study was to evaluate the effectiveness of biofilters for reducing the ...

Two cyanobacterial strains can be distinguished from each other and other eukaryotic algae by spectral absorption method
Spectral absorption method based on two step linear regression analyses (TSLR) was applied for detection of two strains of cyanobacterium, Microcystis (blue-green algae) from eukaryotic algae. Both blue-green algae, algae and dissolved organic carbon (DOC) were considered from freshwater bodies in Kanto region, Japan. The results show that blue-green species can be detected from other algal ...

Investigation of natural organic matter (NOM) character and its removal in a chlorinated and chloraminated system at Rand Water, South Africa
In its natural environment, natural organic matter (NOM) is not problematic. However, during water treatment NOM does affect water quality specifically during the disinfection step, where if NOM is present it reacts with disinfectants resulting in the formation of disinfection by-products. To emphasize the importance of NOM monitoring during potable water treatment this study aimed to ...

Bacteriological water quality changes in parallel pilot distribution systems
In a component of an extensive pilot distribution system (PDS) study, the effects of four different water qualities on biological stability in distributed water were investigated through identical (parallel) single-pass pipe arrangements. Through 24 months of monitoring, a number of key observations were made. Incorporation of a biological treatment step reduced the overall dissolved organic ...

Organic Matter in Drinking Water: A Guide for Simple Online Monitoring
Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics, emerging contaminants, and even counter-terrorism or water security. Despite the critical need, many plants still rely primarily on ...
