Yimaphi Amakhemikhali Okuhlanza Amanzi Adinga Ithangi le-NSF/ANSI 61
I-NSF/ANSI 61 isebenza kulokho okuthinta amanzi okuphuza, hhayi kumakhemikhali jikelele. Umbuzo uwukuthi ikhemikhali eligciniwe lizothinta amanzi aphuzwayo yini.
Ithangi lidinga isitifiketi se-NSF/ANSI 61 lapho ligcina ikhemikhali elisetshenziswa emanzini aphuzwayo futhi indawo yalo emanzi ingangena kulawo manzi, njengama-coagulant, i-chlorine, izilungisi ze-pH ne-fluoride, hhayi lapho ligcina amakhemikhali okusetshenziswa okungekona okuphuzwayo noma kwenqubo.
Ithangi le-NSF/ANSI 61 yilelo izinto zalo ezimanzi eziqinisekisiwe ngokwezinga lempilo yamanzi aphuzwayo. Isizathu ukuthinta amanzi aphuzwayo, hhayi ingozi yekhemikhali ngokwayo.
Izici Ezibalulekile, Izingxenye Nezinhlobo
Amakhemikhali asetshenziselwa emanzini aphuzwayo: Ama-coagulant (alum, PAC, ferric), izibulala-magciwane (i-chlorine, i-chlorine dioxide, ukuthintana ne-ozone), izilungisi ze-pH (i-caustic, i-acid), ne-fluoride konke kuthinta amanzi okuphuza futhi kudinga izindawo ezimanzi eziqinisekisiwe.
Ukugcinwa kanye nokuthintana: Ithangi elibamba ikhemikhali ehlanzekile ngaphambi kokufakwa kwesilinganiso lidinga isitifiketi uma ikhemikhali, noma indawo yaso yesitsha, ingangenisa izinto ezingcolisayo emanzini afakiwe.
Ukungafaki emanzini okuphuzwayo: Amathangi ezinhlobo zikakhemikhali ezingcolile, ezimbonini, ezindaweni zokuhlanza amanzi noma ezinqubweni ezingathintani namanzi okuphuzwayo awadingi i-NSF/ANSI 61.
Izinhlelo zokusebenza kanye Nezimo Zokusetshenziswa
Izitshalo zikamasipala zamanzi okuphuzwayo, izinhlelo zamanzi okuphuzwayo aphakethekile, kanye nanoma yisiphi isikhungo esigcina amakhemikhali okwelapha afakwa kamuva emanzini okusetshenziswa abantu.
Ukucatshangelwa Kwezobuchwepheshe
Umthetho osebenzayo uthi: landelela ikhemikhali kusukela ethangini kuze kufike empompini. Uma indawo yayo emanzi noma ikhemikhali ngokwayo ingafaka izinto ezincibilikayo emanzini abantu abawaphuzayo, ukumbozwa kwethangi, isembozo sangaphakathi, izivalo kanye nezinto zokuxhuma kufanele ngakunye kube ne-NSF/ANSI 61 ngokwakhiwa kwazo. Ithangi losuku noma ithangi lokuxhumana ngokusobala liyafaneleka; ithangi lokugcina elikhulu elingaphezulu nalo liyafaneleka ngoba ikhemikhali isuka lapho iya emanzini aphuzwayo.
Lapho ikhemikhali isetshenziswa kuphela ekwelashweni okungaphuzwayo (amanzi angcolile ezimbonini, ukupholisa, udaka), i-NSF/ANSI 61 akusona isilinganiso esifanele, futhi ukusicacisa kwengeza izindleko ngaphandle kwenzuzo. Hlanganisa imfuneko yamanzi aphuzwayo nezilinganiso zesakhiwo nokumboza okufanele zithangini ngomsebenzi walo.
Izinzuzo Nezingqinamba
Izinzuzo:
Ukusebenzisa i-NSF/ANSI 61 kuphela lapho kukhona ukuthintana namanzi okuphuza kwenza ukuhambisana kube nencazelo futhi kugweme ukukhokhela isiqinisekiso emsebenzini ongewona owamanzi okuphuza.
Imikhawulo:
Izinga lihlanganisa izinto ezincibilikayo ezinomthelela empilweni, hhayi ukusebenza kwesakhiwo noma ukugqwala, ngakho kufanele kuhambisane nalokho. Ukulandelela izindlela zokuthintana kudinga ukunakekela, ithangi elikhulu 'elingathinti amanzi okuphuza' lingase lisaphake umugqa womthamo wamanzi okuphuza.
Ukuqhathanisa & Umhlahlandlela Wokukhetha
Umsebenzi wamakhemikhali | Ingabe i-NSF/ANSI 61 iyadingeka? |
I-coagulant efakwa emanzini okuphuzwayo | Yebo |
Isibulala-magciwane (Cl, ClO2) kumanzi aphuzwayo | Yebo |
I-pH / i-fluoride kumanzi aphuzwayo | Yebo |
Ikhemikhali yamanzi angcolile ezimbonini | Cha |
Ikhemikhali yokupholisa / yenqubo | Cha |
Izinqubo Ezinhle Kakhulu Nokuthi Ungakhetha Kanjani
Landelela ikhemikhali ngayinye kusukela ethangini kuze kufike empompini; qinisekisa ukwakheka okumanzi lapho kungenzeka khona ukuthinta amanzi aphuzwayo. Cela izitifiketi eziqondene nokwakheka kwe-coating, i-liner, izivalo kanye nezinto zokuxhuma, futhi ungacacisi i-NSF/ANSI 61 emsebenzini ongewona owamanzi aphuzwayo ngempela.
Ithangi lidinga i-NSF/ANSI 61 lapho ligcina ikhemikhali efakwa emanzini aphuzwayo, okungukuthi indawo yayo emanzi ingancibilika kulawo manzi. Landelela indlela yokuxhumana bese uqinisekisa lapho, hhayi yonke indawo.
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe amathangi e-chlorine ne-coagulant adinga i-NSF 61?
Uma egcina amakhemikhali afakwa emanzini okuphuza, yebo, izindawo zawo ezimanzi zingafaka izinto ezincibilikayo emanzini okuphuza futhi kufanele ziqinisekiswe ngokwakheka kwazo.
Ingabe ithangi lokugcina amakhemikhali amaningi liyayidinga?
Uma leyo khemikhali kamuva ifakwa emanzini okuphuza, yebo, ngoba isuka ekugcinweni kwamaningi iye emugqeni wokufaka umthamo. Landelela indlela isuka ethangini iya empompini ukuze unqume.
Ingabe i-NSF 61 ayidingeki nini kumakhemikhali?
Kumakhemikhali asetshenziswa kuphela emsebenzini ongahlangene namanzi okuphuzwayo, njengamanzi angcolile ezimbonini, ukupholisa noma ukwelashwa kwenqubo, i-NSF/ANSI 61 ayilona izinga elisebenzayo.
Ingabe i-NSF 61 ihlanganisa ukuphepha kwekhemikhali?
Cha. Ihlanganisa umphumela wezempilo wezinto ezimanzi zethangi emanzini okuphuzwayo, hhayi izingozi zokuphatha ikhemikhali, okuyindaba ehlukile yokuphepha.
Kuthiwani ngezimpawu nezinto zokuxhuma?
Ingxenye ngayinye ethinta amanzi aphuzwayo, kufaka phakathi izivalo, ama-gasket kanye nezinto zokuxhuma, kufanele ibe ne-NSF/ANSI 61 ngokwakheka kwayo, hhayi nje i-coating yethangi.
