Ndi kutentha kwa zochitika zosambira ku Beijing 2008 Olympic Games, kutchuka kwa maiwe osambira ndi kusintha kwa kalasi, ena akhoza kukwaniritsa zofunikira za khalidwe lamadzi lapamwamba komanso luso lamakono lopulumutsa mphamvu, zida zatsopano, zamakono zatsopano, zimayikidwa pang'onopang'ono mu malo osambira ambiri. Kaya dziwe losambira kumene anamanga (natatorium) kapena dziwe losambira akadali mu kukonzanso dziwe akukumana ndi vuto la kusankha bwino dziwe madzi kufalitsidwa kusefera.

Makhalidwe a diatomite amatsimikizira gawo lake. Diatomite imadziwika ndi kuphulika kwakukulu, kutsika kochepa, malo akuluakulu enieni, osasunthika, kukhazikika kwa mankhwala, kusakhala ndi poizoni komanso kosakoma. Ndibwino kwambiri fyuluta wothandizira zakuthupi. Ukadaulo wosefera wapakhomo pazachimbudzi, mowa, kusefera kwazakudya ndi zakumwa zimakhala ndi ntchito zosiyanasiyana.

M'mayiko akunja, teknoloji ya diatomite filtration ndi zipangizo zakhala zikugwiritsidwa ntchito kwambiri poyendetsa madzi amadzimadzi osambira. Chifukwa cha kutengeka kwamphamvu kwa chithandizo cha sefa ya diatomite, imatha kuyamwa madzi 1.5-4 kuchulukitsa kwake. Kuthekera kwake ndi koyipa, mtengo wake wonse ndi waukulu, ndipo kuthekera kwake kotengera mtengo wabwino ndi wamphamvu. Chifukwa chachikulu chapadera pamwamba m'dera ndi pamwamba adsorption ndi zina zotero, kuvula khola colloidal osatetezeka adsorption pa diatomite, ndi adhesion pakati pa diatomite particles wa zoipitsa mu mutual adsorption mphamvu ndi lalikulu, kotero woyengeka kusinthidwa diatomite ntchito madzi mankhwala, akhoza mwamsanga kupanga lalikulu ndi flocs flocs ndi graty flocs ndi zabwino. pamene flocs anathyoledwa, komanso akhoza kuchitika kachiwiri flocculation. Zosefera thandizo ndi ena zitsulo zotayidwa mchere, mchere chitsulo, monga wamba zinyalala wa flocculant sangathe kufika, diatomite yaikulu yeniyeni pamwamba, adsorption amphamvu ndi pamwamba katundu magetsi, kupanga zake mu ndondomeko ya mankhwala madzi, osati kuchotsa mphira tinthu boma ndi kaimidwe wa zoipitsa, ndipo angathe kuchotsa chromaticity ndi kukhalapo mu kusungunuka thetrophi kutsogolera chifukwa chitsulo ndi phosphorous. ion, etc.
