Abstract

The present invention relates to a method and a use of naphthalene sulphonate salts) under granulated form or as a con-densed or diluted solution, and a solution of one or several polyethylene oxide having a molecular weight varying from 1 x 10 6 to 13 x 10 6, allowing for a mixture comprising lignocellulosic particles and an aqueous medium to significantly improve the retention of particles such as fines and fibers, on a wire screen and the drainage of the aqueous medium.
