The plywood effluent is one of the high polluting effluent amongst the effluents obtained from wood industries. The wastewater after birch wood hydrothermal treatment contain hemicelluloses and lignin substances (HLES). The coagulation is one of the cheapest process for treatment of various organic effluents. It is necessary to combine the method of coagulation with the method of post-treatment for providing the technology reliability and possibility of return of the purified water in a main technological cycle. It is set that the process of ozonation got the widest use as the second stage of purification. Thus, the removal of HLES, lignin, chemical oxygen demand (COD) and colour of wastwater is studied using coagulation and ozonation process
