Cov no nquag siv hauv tsev kho mob, chav phais, chav ua noj thiab chav dej uas cov kab mob muaj peev xwm loj hlob sai thiab kis kab mob exponentially. Cov tshuaj tua kab mob zoo tshaj plaws tuaj yeem ua kom tsis muaj menyuam tag nrho, tab sis nws tsis yog qhov xwm txheej ib txwm. Thaum cov tshuaj no tau siv qee cov kab mob ua kom tsis muaj zog tiv thaiv lawv thiab ua rau qhov xwm txheej tsis zoo. Yog li ntawd, qee zaum cov concentrations siv yuav tsum tau nce siab.
Cawv, aldehydes, oxidizing agents, thiab tshuaj bleach hauv tsev yog cov tshuaj tua kab mob nrov heev. Iodine, ozone, nyiaj, thiab tooj liab ntsev kuj siv nyob ntawm daim ntawv thov.
