Aquaculture yog ib qho kev lag luam tseem ceeb uas muab ib feem tseem ceeb ntawm lub ntiaj teb cov khoom noj nqaij nruab deg. Txawm li cas los xij, nws tseem tsim cov dej khib nyiab ntau uas muaj ntau yam kuab paug. Txhawm rau txo qhov cuam tshuam ib puag ncig, yuav tsum muaj txoj kev kho kom zoo.
Polyacrylamide (PAM) yog ib hom linear organic polymer, tab sis kuj yog ib hom ntawm polymer dej kho flocculant khoom, muaj peev xwm adsorption suspended hais nyob rau hauv dej, qhov kev sib txuas ntawm cov particles choj, kom cov zoo hais los tsim ib tug kuj loj flocculation, thiab ua kom nrawm nrawm ntawm nag lossis daus.
Cov txheej txheem no yog hu ua flocculation, vim nws cov nyhuv flocculation zoo PAM ua flocculant ntawm kev kho dej thiab yog siv dav hauv kev kho dej phwj. Tshwj xeeb tshaj yog nyob rau hauv aquaculture, muaj kev xav tau siab heev rau cov dej zoo thiab kev kho cov dej phwj zoo.
