Indasitiri yemapepa echimbuzi kusvibiswa kwemvura yakakomba, ine, drainage (kazhinji inodarika matani mazana matatu emvura patani yepulp nebepa rechimbuzi), mvura ine tsvina mune yakakwira yezvinhu organic zvinhu, biochemical oxygen kudiwa (BOD) yakakwirira, yakamiswa solids (SS) zvimwe, uye ine chepfu zvinhu, ine ruvara rune hunhu hunokanganisa kunhuhwirira kwemaindasitiri, uye kuchengetwa kwemhuka uye vagari vemvura uye nzvimbo yezvakatipoteredza. Kuunganidzwa nekufamba kwemakore, zvimedu zvakaturikwa zvinonyorovesa chiteshi chengarava cherwizi, uye kuburitsa hydrogen sulphide inonhuwa ine muchetura, kukuvadza kunosvika kure.
Kusvibisa masosi Maitiro makuru muindasitiri yemapepa echimbuzi kugadzirira zvinhu, kupuruzira, kudzoreredza alkali, kuchena, kukopa bepa rechimbuzi uye zvichingodaro. Iyo mbishi yekugadzira nzira inoburitsa huruva, bark, huni machipisi, huswa hunopera; pulping uye alkali kupora, bleaching process inoburitsa gasi rekubuda, guruva, tsvina yemvura, lime residue, nezvimwe; Toilet paper copying process inoburitsa mvura chena, zvese zvine zvinosvibisa. Kusvibiswa kweindasitiri yemapepa echimbuzi kune zvakatipoteredza kunogona kukamurwa kuita zvikamu zvitatu zvekusvibiswa kwemvura (Tafura 1), kusvibiswa kwemweya (Tafura 2) uye kusvibiswa kwemarara.
