Fokotsa Letamo la Hao ka Aluminium Sulphate

Metsi a matamo a nang le maru a eketsa kotsi ea mafu a tšoaetsanoang le ho fokotsa ts'ebetso ea li-disinfectants, kahoo metsi a letamo a lokela ho phekoloa kaflocculantska nako e loketseng. Aluminium Sulphate (eo hape e bitsoang alum) ke sebaka se setle ka ho fetisisa sa letamo bakeng sa ho theha matamo a hlakileng le a hloekileng a ho sesa.

Kamoo Aluminium Sulphate e Sebelisang Metsi a Letamo kateng

Ka phekolo ea letamo, ha e qhibiliha ka metsing aluminium sulphate e theha flocculant e hohelang lintho tse tiileng le litšila tse emisitsoeng le ho li tlama ho tsona, ho etsa hore ho be bonolo ho arohana le metsi. Haholo-holo, aluminium sulfate e qhibilihisitsoeng ka metsing e tla qhibiliha butle-butle ho theha Al(OH) 3 colloid e nang le "positively charged", e khonang ho kenya likaroloana tse emisitsoeng ka mokhoa o fosahetseng ka metsing, ebe e kopana kapele ebe e lula tlase ho metsi. Joale sediment e ka aroloa ho tloha metsing ka sedimentation kapa filtration.

Sediment se tlhotloa ka ntle ho metsi, ho fokotsa bongata ba lintho tse silafatsang ka metsing le ho fokotsa litšenyehelo tsa ho hloekisa litšila.

aluminium sulphate e fa letamo 'mala o hloekileng le o hlakileng o moputsoa kapa o moputsoa o motala.

Litaelo tsa ho Sebelisa Aluminium Sulphate ka Phekolo ea Metsi

1. Tlatsa bakete ea polasetiki hoo e ka bang halofo e tletseng metsi a letamo. Hlakola botlolo, 'me u kenye aluminium sulfate ka tekanyo ea 300 ho isa ho 800 g ka 10,000 L ea metsi a letamo ho ea ka nkhong, tsosa ka bonolo ho kopanya hantle.

2. Tšela tharollo ea aluminium sulfate holim'a metsi ka ho lekana 'me u boloke tsamaiso ea potoloho e sebetsa bakeng sa potoloho e le' ngoe.

3. Eketsa pH Plus ho boloka pH le kakaretso ea alkalinity ea letamo la ho sesa le phekoloang.

4. Lumella letamo hore le eme le sa khathatsehe ntle le hore pompo e sebetse lihora tse 24 kapa ka ho khetheha lihora tse 48 haeba ho khoneha bakeng sa liphello tse ntle.

5. Qala pompo hona joale 'me u lumelle maru leha e le afe a setseng hore a bokelloe ka har'a sefa, haeba ho hlokahala, sebelisa roboto e hloekisang ho tlosa sediment fatše letamong.

Qetellong, karolo eaflocculant letamo la ho sesaka disinfection ea letamo la ho sesa boleng ba metsi ke ea bohlokoa haholo, 'me tšebeliso e nepahetseng ea flocculant ea letamo la ho sesa e lokela ho ntlafatsa ka katleho boleng ba metsi a letamo la ho sesa le ho theha tikoloho ea ho sesa e phetseng hantle le e phutholohileng bakeng sa batho ba sesang.
