Ukwethulwa kokwelashwa kwe-XJY sludge Ngaphambi kuka-1950, imiphakathi eminingi yase-United States yayichitha amanzi ayo angcolile, noma indle, emifuleni nasemifuleni ngaphandle kokwelashwa okuncane. Njengoba abantu basemadolobheni banda, ikhono lemvelo lemifudlana nemifula...

Inqubo yokwelashwa kwe-XJY sludge ibandakanya izigaba ezimbalwa ezibalulekile, okuhlanganisa ukubola kwebhayoloji, ukuqeda udaka, ukomiswa kodaka, kanye nemishini yokususa uthuli.

Amanzi asebenzisekayo ayinsiza encipha ngokushesha e-United States. Ngaphandle kokongiwa kwemvelo, izinhlelo ezifakwa ezimbonini zokukhipha usawoti emanzini zinikeza indlela ekahle yokukhiqiza amanzi athembekile, ahlanzekile. Ezifundeni ezifana neFlorida, iTexas neCalifornia lapho amanzi ahlanzekile eyivelakancane ukuqala, imiphakathi iyaphoqeleka ukuthi icabangele eminye imithombo yamanzi aphuzwayo. Ngaphandle kokongiwa kwemvelo, izinhlelo ezifakwa ezimbonini zokukhipha usawoti emanzini zinikeza indlela ekahle yokukhiqiza amanzi athembekile, ahlanzekile.

Njengoba inani labantu emhlabeni liqhubeka nokukhula kanye nokushintsha kwesimo sezulu kwandisa izinkinga zokushoda kwamanzi, isidingo samanzi ahlanzekile, aphuzwayo sifinyelela emazingeni angakaze abonwe. Imithombo yamanzi yendabuko iyancipha, okuholela ekukhathazekeni okukhulu mayelana nokutholakala okusimeme kwamanzi okuphuza ahlanzekile. Kulo mongo, ukuchithwa kweziqukathi usawoti kasawoti kuvela njengesixazululo esisha, esinikeza izindlela eziphathwayo neziphumelelayo zokuguqula amanzi olwandle anosawoti abe amanzi ahlanzekile asebenzisekayo.

Ngenxa yokukhula kokuntuleka kwamanzi emhlabeni wonke, ikakhulukazi emiphakathini yasogwini naseziqhingini, ukukhishwa kwamanzi olwandle usawoti kuye kwavela njengobuchwepheshe obubalulekile ekukhiqizeni amanzi ahlanzekile, aphuzwayo. Izitshalo zendabuko zokususa usawoti emanzini, nakuba zisebenza kahle, zivame ukudinga ingqalasizinda ebalulekile nezinsiza. Kodwa-ke, ukuvela kwezinhlelo zokususa usawoti emanzini olwandle aneziqukathi kuye kwayishintsha kakhulu le ndawo, kwanikeza enye indlela evumelana nezimo, eyongayo, futhi evumelana nemvelo.

Igesi eliwudoti lingeniswa embhoshongweni wokuhlanza ngokusebenzisa ipayipi lomoya, lidlula ungqimba lokupakisha, futhi igesi engcolile kanye noketshezi lokumuncwa kuthintwa ngokugcwele futhi kudonswe ukusabela kwe-gas-liquid kwezigaba ezimbili ze-neutralization.

Ama-Electrostatic precipitators (ESPs) angamathuluzi abalulekile asetshenziswa izimboni ezihlukahlukene ukususa izinhlayiya kumagesi akhipha umoya ukuze kulawulwe ukungcoliswa komoya. Ziyinketho ephumelelayo, esebenzayo futhi enobungani nemvelo yokugcina izinga lomoya. Lesi sihloko...

Asebenza kanjani ama-electrostatic precipitators? Umgomo oyisisekelo ngemuva kwe-ESPs ukukhanga kwe-electrostatic phakathi kwezinhlayiya ezishajwayo kanye nezindawo ezishajwe ngokuphambene. Inqubo ingahlukaniswa ngobubanzi izigaba ezine: 1.Ukushaja: Njengoba i-exhaust gas ente...
