Lab-scale research of water treatment with use of water glass and nanoiron

摘要

The article describes the partial outputs of the research focusing on alternative procedures and agents for water treatment. In this case, the possibilities are shown of using water glass and nanoiron as agents for removing heavy metals and nutrients from the water. In particular, laboratory experiments are presented simulating the processes of removing chromium and phosphorus from water. The purpose of the experiments was to show the efficiency of mentioned alternative agents when removing the pollution mentioned. The laboratory experiment was conceived as a series of jar tests as standard procedure used in connection with the control and optimisation of the coagulation process. Laboratory processes were carried out with model water whose main component was raw water from a surface water source enriched with a previously given concentration of selected pollution - chromium and phosphorus. During the experiments, the dependence was determined of the removal of the given pollution on the dose of the agent and simultaneous search for the optimal dose while applying water glass and/or nanoiron as innovative agents.
