Chlorate as a by-product of disinfection by sodium hypochlorite
Drdová, Š. ; Parschová, H. ; Pivokonský, Martin ; Janda, V.
The study deals with the formation of chlorate as a disinfection by-product when using sodium hypochlorite. The relationship between aging and storing conditions of sodium hypochlorite and the production of chlorite and other DBPs was investigated.
The adsorption of low-MW algal organic matter on granular activated carbon
Čermáková, Lenka ; Pivokonská, Lenka ; Kopecká, Ivana ; Pivokonský, Martin ; Janda, V.
This study deals with the adsorption of algal organic matter (AOM) onto granular activated carbon (GAC) with a special focus on compounds with low molecular weight (MW). These were isolated from cellular matter of cyanobacterium Microcystis aeruginosa. Two different types of GAC were used for the experiments (Picabiol 12x40 and Filtrasorb TL 830) and the influence of pH and ionic strength on the adsorption efficacy of the low-MW AOM was investigated.
The influence of algal organic matter on the coagulation of humic substances
Novotná, Kateřina ; Drdová, Š. ; Načeradská, Jana ; Pivokonský, Martin ; Janda, V.
The article deals with coagulation of humic substances (HS) in presence of cyanobacterial peptides/proteins produced by Microcystis aeruginosa. The results show that the peptides/proteins may have a positive impact on the coagulation of HS – under certain conditions, higher removal was achieved using lower coagulant dosage. Additionally, the existence of interactions between the peptides/proteins and HS was proved.
What is the impact of algal organic matter on drinking water treatment processes?
Pivokonský, Martin ; Janda, V.
The paper is focused on the influence of AOM (Algal Organic Matter) on coagulation during drinking water treatment. Composition and properties of AOM are discussed as well as the impact of these compounds on the mechanisms and efficacy of coagulation.
