The efficiency of removal of cellular organic matter (COM) of cyanobacteria Microcystis aeruginosa from water with ferric sulfate is influenced primarily by coagulant dosage and reaction pH. Therefore, optimization of the reaction conditions is a prerequisite for efficient purification of surface waters. Because the isoelectric point of COM occurs at a low pH, the purification of waters containing this organic matter should take place in an acidic pH range. It was also found that proteins are removed more efficiently than other organic substances (mainly polysaccharides). Water Environ. Res., 81, 514 (2009).

The aim of this contribution is to investigate aggregation efficiencies when a fluidised layer of granular material (FLGM) is applied for a treatment of surface water with high DOC (Dissolved Organic Carbon) and low alkalinity in a pilot size operation. It was shown that the FLGM can be effective for agitation of a system using destabilised particles with the aim to form readily separable suspension. An aggregation efficiency of the FLGM reactor was evaluated by the degrees of destabilisation and aggregation of the particles of impurities. The maximal separation efficiencies of the pilot plant after filtration attained φAl = 0.96 and φDOC = 0.73. These values exceeded not negligibly the ones reported for the conventional aggregation processes.

Review question / Objective: The aim of the present study was to conduct a systematic search in order to find available tools for monitoring and evaluating the mental health literacy of children and adolescents under the age of 19 years. Condition being studied: Mental health literacy is an essential part of mental illness prevention and early-identification. Number of tools exist to assess mental health literacy in the adult population. However, very few studies focus on tools that are aimed at assessing mental health literacy of children and adolescents, and evaluate quality of these tools.
