2. Ukuzwela kwesinciphisi samanzi se-polycarboxylic acid kokuqukethwe udaka
Okuqukethwe kodaka ezintweni ezingavuthiwe zikakhonkolo, isihlabathi namatshe, kuzoba nomthelela ongenakuhlehliswa ekusebenzeni kukakhonkolo futhi kunciphise ukusebenza kwesinciphisi samanzi se-polycarboxylic acid. Isizathu esiyisisekelo siwukuthi ngemva kokuba isinciphisi samanzi se-polycarboxylic acid sikhangiswe ubumba ngobuningi, ingxenye esetshenziselwa ukuhlakaza izinhlayiya zikasimende iyancishiswa, futhi ukuhlakazeka kuba mpofu. Lapho udaka esihlabathini luphezulu, izinga lokunciphisa amanzi le-polycarboxylic acid enciphisa amanzi lizoncishiswa kakhulu, ukulahleka kokuwa kukakhonkolo kuzokwanda, uketshezi luzokwehla, ukhonkolo uzothambekela ekuqhekekeni, amandla azokwehla, futhi ukuqina kuzowohloka.

Kunezixazululo ezimbalwa ezijwayelekile zenkinga yamanje yodaka:
(1) Khulisa umthamo noma ukhuphule Engeza i-ejenti evimbela ukugoqeka kancane kancane engxenyeni ethile, kodwa ulawule inani ukuze uvimbele ukuphuzi, ukopha, ukuhlukaniswa, ukubanjwa okuphansi kanye nesikhathi eside kakhulu esimisiwe sikakhonkolo;
(2) Lungisa isilinganiso sesihlabathi noma wandise inani le-ejenti yokungenisa umoya. Ngaphansi kwesisekelo sokuqinisekisa ukusebenza okuhle namandla, ukunciphisa isilinganiso sesihlabathi noma ukwandisa inani le-ejenti yokungenisa umoya ukwandisa okuqukethwe kwamanzi mahhala nokunamathisela umthamo wesistimu yekhonkrithi, ukuze ulungise ukusebenza kokhonkolo;
(3) Engeza noma uguqule izingxenye ngendlela efanele ukuze uxazulule inkinga. Ukuhlola kubonise ukuthi ukwengeza inani elifanele le-sodium pyrosulfite, i-sodium thiosulfate, i-sodium hexametaphosphate ne-sodium sulfate kusinciphisi samanzi kunganciphisa umthelela wokuqukethwe kodaka kukhonkolo ngokwezinga elithile. Yiqiniso, lezi zindlela ezingenhla azikwazi ukuxazulula zonke izinkinga zodaka. Ukwengeza, umthelela wodaka ekuqineni kukakhonkolo udinga ukucwaninga okwengeziwe, ngakho-ke ikhambi eliyisisekelo ukwehlisa okuqukethwe kodaka lwempahla eluhlaza.
