Yabelana ngokugqwala okuvamile okuvamile abantu abavame ukungawanaki

I-angle yamanzi efile

Noma yimuphi umbhoshongo opholile ovulekile empeleni uyisihlanza somoya omkhulu ongasusa ukungcola komoya okuhlukahlukene. Ngaphezu kwama-microorganisms, ukungcola, izinhlayiya nezinye izindikimba zakwamanye amazwe, amanzi aphansi kepha abuye athuthukise kakhulu umsebenzi wokugqwala. Ngalesi simiso esivulekile, ngenxa yezindleko eziphakeme zamakhemikhali, ukwelashwa kwamakhemikhali kuhlale kugcinwa ezingeni eliphansi, okuholela ekulahlekelweni okukhulu kokugqwala. Ezimweni eziningi, ukuhlunga kwamanzi akwanele, kuvumela noma yiziphi izinhlayiya zakwamanye amazwe ezingena ohlelweni ukuze zihlale lapho unomphela. Ngaphezu kwalokho, amanani amakhulu we-iron oxide nolunye udaba lokuhlangana abuthane ndawonye, ​​ukudala izinkinga eziningi zesibili zokugqwala ezinhlelweni ezivulekile zamanzi avulekile.

 2. Amapayipi okushisa aphindwe kabili

Emuva ngawo-1950s, amafulethi athile azimele, amakhondomu, kanye nezakhiwo ezithile zehhovisi zazibonisa ukufudumala okuvame kakhulu ukufudumeza nokupholisa, futhi lezi zinhlelo zokushisa amapayipi okushisa ziseduze nokuphela kwezimpilo zazo eziwusizo ezweni lonke.

Lo mklamo omuhle futhi olula wokushisa nokushisa okulula uvame ukusetshenziselwa ukuhlinzeka ngamanzi ashisayo noma abandayo kuyunithi yabalandeli bewindows ngokubeka amashubhu anciphile futhi amashubhu amancane afakwe amashubhu angama-40-carbon ku-perimeter colommum Supports. Ezinye izinto zokufakwa okushisayo zivame ukuncishiswa njengezincane njenge-1-inch fiberglass, kepha azilungele ngokuphelele izinhlelo zokusebenza ngoba zingena kalula umswakama futhi kuhlale zinzima ukufaka endaweni efanele. Ipayipi lensimbi ngokwalo alikaze lidwetshwe, lihlanganiswe noma lilwa nokulwa nokuvikela ungqimba, ukuze amanzi angena ngaphakathi kongqimba lokufakelwa bese alwela ipayipi kusuka ngaphakathi.
