Iphepha le-Thermal sisixhobo esisetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo aquka ukuthengisa, ibhanki kunye nelolungiselelo.Iqatywe ngedayi ekhethekileyo etshintsha umbala xa ifudunyezwa, iyenze ilungele ukuprinta iirisithi, iilebhile kunye nezincamathelisi zebhakhowudi.Nangona kunjalo, iphepha le-thermal alikwazi ukuphinda lisetyenziswe ngeendlela zemveli zokuphinda zenziwe ngokutsha ngenxa yobukho beekhemikhali kunye nokungcola.Ngoko ke, iinkqubo ezikhethekileyo zifunekayo ukuphatha ngokufanelekileyo kunye nokuphinda kusetyenziswe iphepha le-thermal kunye nokunciphisa impembelelo yalo kwindalo.Kweli nqaku, siza kuphonononga amanyathelo abandakanyekayo ekusetyenzweni nasekusetyenzisweni ngokutsha kwephepha le-thermal.
Isinyathelo sokuqala kwinkqubo yokubuyisela kwakhona kukuqokelela iphepha elisetyenzisiweyo le-thermal.Oku kunokwenziwa ngeendlela ezahlukeneyo, ezinjengokubeka imigqomo yokuqokelela ezinikeleyo kwiivenkile ezithengisayo nakwii-ofisi, okanye ukusebenza neenkampani zokurisayikilisha ukuqokelela inkunkuma yamaphepha ashushu.Ukwahlula okufanelekileyo kubalulekile ukuqinisekisa ukuba iphepha le-thermal kuphela liqokelelwa kwaye lingaxutywanga kunye nezinye iintlobo zephepha.
Xa sele iqokelelwe, iphepha le-thermal lihanjiswa kwindawo yokubuyisela kwakhona apho lihamba ngeendlela ezininzi zokususa idayi kunye nezinye izinto ezingcolileyo.Isinyathelo sokuqala kwisigaba sokucubungula kuthiwa yi-pulping, apho iphepha le-thermal lixutywa namanzi ukuze lihlehlise libe yimicu yodwa.Le nkqubo inceda ukwahlula idayi kwimicu yephepha.
Emva kwe-pulping, umxube uhlolwe ukususa nayiphi na i-particle esele eqinile kunye neengcoliseko.Ulwelo oluphumayo luthi ke lufakwe kwinkqubo yokudada, apho amaqamza omoya aziswa ukwahlula idayi emanzini.Idayi iba khaphukhaphu kwaye idada ngaphezulu kwaye iyacolwa, ngelixa amanzi acocekileyo alahlwayo.
Isinyathelo esilandelayo kwinkqubo yokubuyisela kwakhona kukususa imichiza ekhoyo kwiphepha le-thermal.Ezi khemikhali ziquka i-bisphenol A (BPA), esebenza njengomphuhlisi wedayi ephepheni.I-BPA sisiphazamisi se-endocrine esaziwayo esibeka umngcipheko kwimpilo yabantu kunye nokusingqongileyo.Iintlobo ezahlukeneyo zobuchwepheshe, ezifana ne-carbon adsorption kunye ne-ion exchange exchange, zingasetyenziselwa ukususa i-BPA kunye nezinye iikhemikhali emanzini.
Emva kokuba idayi kunye neekhemikhali zisuswe ngokufanelekileyo emanzini, amanzi ahlambulukileyo angaphinda asetyenziswe okanye akhululwe emva kokunyanga okufanelekileyo.Iintsinga zephepha eziseleyo ngoku zinokulahlwa njengeendlela zemveli zokurisayikilishwa kwephepha.Ipulp iyahlanjwa, icocwe kwaye ifakwe ibleach ukuphucula umgangatho wayo phambi kokuba isetyenziswe ukwenza iimveliso zephepha ezintsha.
Kufuneka kuqatshelwe ukuba ukuphinda kusetyenziswe iphepha le-thermal yinkqubo enzima efuna iteknoloji ephezulu kunye nezixhobo.Ke ngoko, kubalulekile kumashishini nakubantu abasebenzisa iphepha lobushushu ukuba basebenze nesibonelelo esivunyiweyo sokurisayikilishwa kwakhona ukuze kuqinisekiswe ukuphathwa ngendlela eyiyo kunye nokurisayikilishwa kwakhona.
Ukuqukumbela, iphepha le-thermal, nangona lisetyenziswa ngokubanzi, libonisa imingeni yokuphinda isetyenziswe ngenxa yobukho beekhemikhali kunye nokungcola.Ukusetyenzwa kunye nokuhlaziywa kwephepha le-thermal kubandakanya amanyathelo amaninzi, kubandakanywa i-pulping, i-flotation, ukususwa kweekhemikhali kunye nonyango lwefayibha.Ngokuphumeza iindlela ezifanelekileyo zokuqokelela kunye nokusebenza kunye nabahlaziyi, sinokunciphisa ngokufanelekileyo impembelelo yokusingqongileyo yephepha le-thermal kunye nokukhuthaza izenzo zokulawula inkunkuma ezinzileyo.
