Kutsekera kwamadzi ndi chinthu chovuta kwambiri pamapulogalamu ambiri obisika, makamaka omwe amagwiritsidwa ntchito m'malo ovuta. Cholinga cha kutsekereza madzi ndikutchinjiriza madzi kuti asalowe chingwe ndi kuwononga omwe amawononga magetsi mkati. Njira imodzi yothandiza kwambiri yopezera kutsekereza madzi ndikugwiritsa ntchito madzi otsetsereka m'bwalo lomanga.
Madzi oyatsira madzi otsekemera amapangidwa ndi zinthu za hydrophilic zomwe zimatupa zikafika polumikizana ndi madzi. Kutupa kumeneku kumayambitsa chotchinga chomwe chimalepheretsa madzi kuti asalowe chingwe. Zipangizo zomwe zimagwiritsidwa ntchito kwambiri ndizokulirapo polyethylene (epe), polypropylene (ma pp), ndi sodium Polyacrylate (spa).
EPE ndi kapa kachulukidwe kakang'ono kwambiri, wolemera kwambiri polyethylene yemwe ali ndi njira yabwino kwambiri yamadzi. Pamene epe ulusi utakumana ndi madzi, amatenga madzi ndikuwonjezera, ndikupanga chitchinga chodzimadzi mozungulira omwe amachititsa bungwe. Izi zimapangitsa epe chinthu chabwino kwambiri pakuletsa ulusi, chifukwa limateteza kwambiri kumiza madzi.
PP ndi chinthu china chomwe chimagwiritsidwa ntchito nthawi zambiri. Zithunzi za PP ndi hydrophobic, zomwe zikutanthauza kuti amabweza madzi. Mukamagwiritsa ntchito chingwe, ma pp ulusi amapanga chotchinga chomwe chimalepheretsa madzi kuti asalowe chingwe. Zilonda za PP zimagwiritsidwa ntchito limodzi ndi ma epe ulusi kuti mupereke chitetezo chowonjezera ku Whess Stress.
Sodium Pulyacrylate ndi polymer polymer yomwe nthawi zambiri imagwiritsidwa ntchito. Mafuta a Sodium a Polyacrylate amakhala ndi mphamvu yotenga madzi, omwe amawapangitsa kukhala cholepheretsa kugwiritsa ntchito mankhwalawa. Akaluma amatenga madzi ndikukula, ndikupanga chitchinga chodyeramo mozungulira omwe amachititsa.
Madzi oyatsira madzi otsekemera nthawi zambiri amaphatikizidwa mu chingwe pakupanga. Amawonjezeredwa ngati wosanjikiza kuzungulira magetsi, pamodzi ndi zina zophatikizika monga kutukuka ndi kukopa. Zogulitsa zimayikidwa m'malo abwino mkati mwa chingwe, monga chikhocho chimatha kapena madera omwe amakonda kumiza madzi, kupatsa chitetezo chokwanira kuwonongeka kwa madzi.
Pomaliza, mitsinje yotsekereza madzi ndi gawo lofunikira mu zomangamanga zomwe zimafunikira kutetezedwa ku WOSRES. Kugwiritsa ntchito madzi kutsetsereka ulusi monga epe, pp, mas, ndi sodium polyaclate, ndikuwonetsetsa kuti kudalirika kwa chinsinsi.
