Zisebenza njani iikhemikhali zedama lokudada?

Ukuba unedama lakho lokudada ekhaya okanye sele uza kuba ngumlungisi wedama lokudada. Ngoko ke siyakuhalalisela, uza konwaba kakhulu ekugcinweni kwedama lokudada. Ngaphambi kokuba idama lokudada lisetyenziswe, igama elinye ekufuneka uliqonde lelithi “Iikhemikhali zedama".

Ukusetyenziswa kweekhemikhali zedama lokudada yenye yezona zinto zibalulekileyo ekugcinweni kakuhle kwedama lokudada. Kwakhona yeyona nxalenye ibalulekileyo yokulawula idama lokudada. Kufuneka wazi ukuba kutheni ezi khemikhali zisetyenziswa.

Iikhemikhali eziqhelekileyo zedama lokudada:

Izibulali-ntsholongwane ze-chlorine

Ii-chlorine disinfectants ziikhemikhali eziqhelekileyo ekugcinweni kweedama zokudada. Zisetyenziswa njengezibulali-ntsholongwane. Emva kokuba zinyibilikile, zivelisa i-hypochlorous acid, eyinxalenye yesibulali-ntsholongwane esisebenzayo kakhulu. Ingabulala iintsholongwane, iintsholongwane kunye nokukhula okuthe ngcembe kwe-algae emanzini. Ii-chlorine disinfectants eziqhelekileyo yi-sodium dichloroisocyanurate, i-trichloroisocyanuric acid, i-calcium hypochlorite, kunye ne-bleach (isisombululo se-sodium hypochlorite).

I-Bromine

Ii-Bromine disinfectants zizinto ezinqabileyo kakhulu. Ezona zixhaphakileyo yiBCDMH(?) okanye i-sodium bromide (esetyenziswa ne-chlorine). Nangona kunjalo, xa kuthelekiswa ne-chlorine, ii-bromine disinfectants zibiza kakhulu, kwaye kukho abantu abaninzi abadadayo abanovelwano kwi-bromine.

Isilungisi se-pH

I-pH yiparameter ebaluleke kakhulu ekugcinweni kwedama lokubhukuda. I-pH isetyenziselwa ukuchaza ukuba amanzi ane-asidi okanye i-alkaline kangakanani. I-Normal iphakathi kwe-7.2-7.8. Xa i-pH idlula isiqhelo. Inokuba nefuthe elihlukeneyo ekusebenzeni kakuhle kokubulala iintsholongwane, izixhobo kunye namanzi edama lokubhukuda. Xa i-pH iphezulu, kufuneka usebenzise i-pH Minus ukuze wehlise i-pH. Xa i-pH iphantsi, kufuneka ukhethe i-pH Plus ukuze unyuse i-pH iye kuluhlu oluqhelekileyo.

Isilungisi soBulukhuni beCalcium

Olu luvavanyo lobungakanani bekhalsiyam emanzini echibi. Xa inqanaba lekhalsiyam liphezulu kakhulu, amanzi echibi ayazinza, nto leyo ebangela ukuba amanzi abe namafu kwaye abe ne-calcium. Xa inqanaba lekhalsiyam liphantsi kakhulu, amanzi echibi "aya kuyitya" ikhalsiyam ephezu komphezulu wechibi, onakalise izixhobo zesinyithi kwaye abangele amabala. Sebenzisaikhalsiyam chlorideukwandisa ubulukhuni be-calcium. Ukuba i-CH iphezulu kakhulu, sebenzisa i-arhente yokususa iikali ukususa isikali.

Isilungisi se-Alkalinity iyonke

I-alkalinity iyonke ibhekisa kubungakanani beekhabhohayidreyithi kunye nee-hydroxide emanzini echibi. Zinceda ukulawula nokulungisa i-pH yechibi. I-alkalinity ephantsi inokubangela ukuguguleka kwe-pH kwaye kwenze kube nzima ukuzinza kuluhlu olufanelekileyo.

Xa i-alkalinity iyonke iphantsi kakhulu, i-sodium bicarbonate ingasetyenziswa; xa i-alkalinity iyonke iphezulu kakhulu, i-sodium bisulfate okanye i-hydrochloric acid ingasetyenziselwa ukuthomalalisa. Nangona kunjalo, eyona ndlela isebenzayo yokunciphisa i-Total Alkalinity kukutshintsha inxalenye yamanzi; okanye ukongeza i-asidi ukulawula i-pH yamanzi echibini angaphantsi kwe-7.0 kwaye uvuthele umoya echibini nge-blower ukuze ususe i-carbon dioxide ide i-Total Alkalinity yehle iye kwinqanaba elifunekayo.

Uluhlu olupheleleyo lwe-alkalinity yi-80-100 mg/L (kwiidama ezisebenzisa i-CHC) okanye i-100-120 mg/L (kwiidama ezisebenzisa i-chlorine ezinzileyo okanye i-BCDMH), kwaye ukuya kuthi ga kwi-150 mg/L kuvunyelwe kwiidama zeplastiki.

Iiflocculants

Ii-Flocculants nazo zizinto ezibalulekileyo kwiikhemikhali ekugcinweni kwedama. Amanzi edama amdaka awachaphazeli nje kuphela inkangeleko kunye nokuvakala kwedama, kodwa anciphisa nefuthe lokubulala iintsholongwane. Umthombo ophambili we-turbidity ziisuntswana ezixhonyiweyo edamini, ezinokususwa zii-flocculants. I-flocculant eqhelekileyo yi-aluminium sulfate, ngamanye amaxesha i-PAC nayo iyasetyenziswa, kwaye ewe abantu abambalwa basebenzisa i-PDADMAC kunye ne-Pool Gel.

Ezi zingentla zezona zixhaphakileyoiikhemikhali zedama lokudada. Ukuze ukhethe kwaye usebenzise izinto ezithile, nceda ukhethe ngokweemfuno zakho zangoku. Kwaye ulandele imiyalelo yokusebenza yeekhemikhali ngokungqongqo. Nceda uzikhusele xa usebenzisa iikhemikhali.
