Mmetụta nzacha enyemaka nke Diatomite

A na-arụ ọrụ nzacha nke enyemaka nzacha diatomite site na ọrụ atọ ndị a:

1.Sieving mmetụta

Nke a bụ mmetụta nzacha elu. Mgbe mmiri ahụ na-agafe n'ụwa diatomaceous, oghere nke ụwa diatomaceous dị ntakịrị karịa nha nke ihe na-adịghị ọcha, nke mere na ihe adịghị ọcha enweghị ike ịgafe ma na-egbochi ya. A na-akpọ mmetụta a sieving. N'ezie, elu nke keki nzacha nwere ike na-ewere dị ka sieve elu na nha nha nha nha nha. Mgbe dayameta nke ihe ndị siri ike na-erughị (ma ọ bụ ntakịrị ihe na-erughị) na dayameta nke pores nke diatomite, a ga-ewepụ ihe ndị siri ike "si na nkwusioru". Kewapụ, rụọ ọrụ nke nzacha elu.
2. Mmetụta miri emi

Mmetụta dị omimi bụ mmetụta njigide nke nzacha miri emi. Na nzacha miri emi, usoro nkewa ahụ na-eme naanị na "n'ime" nke ọkara.
