Coagulation is an important step of drinking water treatment, while its course and efficiency is determined by many factors. In addition to the composition of treated (raw) water, coagulation is fundamentally affected by variable physico-chemical parameters such as the type and dose of a coagulant, coagulation pH value, water temperature, or mixing conditions. Within this field, we deal with optimisation of coagulation for water of diverse composition with an aim to achieve the maximum possible efficiency of undesirable pollutants removal. Additionally, we focus on the elucidation of mechanisms of coagulation and on the description of interactions between polluting substances and coagulants. We are capable to verify our lab-based findings at a pilot-scale, and we are involved in the transfer of our research results to practice at drinking water treatment plants.

Research Activities

  • Optimisation of chemical parameters of coagulation
  • Investigation of coagulation mechanisms (charge neutralisation, polymer bridging, adsorption onto colloid surfaces, enmeshment, etc.)
  • Investigation of interactions (electrostatic, hydrophobic, hydrogen bonds, van der Waals forces) between particles during coagulation
  • Elucidation of the effects of diverse pollutants on coagulation
  • Development and innovations of coagulation-based water treatment technologies
