| Abstract | FIELD: treatment of sewage water sediments, in particular, slime lignin of wood-pulp and paper industry. SUBSTANCE: method includes treatment of slime lignin with flocculant, water-repelling agent, and dewatering. Water-repelling agent is used in the form of ammonium salt and octylbetathiopropionic acid. Due to increased water loss of sediments and reduced dwell time of sediments on dewatering stage efficiency of vacuum filters, filter presses, flotation machines increases. EFFECT: higher efficiency. 2 tbl |
