After the sewage aeration tanks in the water settles in the secondary clarifier. Purified
water is then chlorinated and then enters the post-treatment in the evaporation ponds, as the
quality of its still does not conform to clear the pond cultural purpose
Quality of treated water is tentatively as follows
рН - 6,5-8,5
BOD5, mg / l - 25
COD mg / l - no more 120
Phenols, mg / l - less 0,15
Petroleum products, mg / l - 2,0
Benzene, mg / l - 0,05
Benzapyrene, mg / l - 0,05
Ammonia nitrogen, mg / l - less 5,0
Suspended solids, mg / l - 20
