Amanzi amdaka ekhemikhali yamalahle
Ishishini lemichiza ephuma kumalahle lisebenzisa amalahle njengemathiriyeli ekrwada ukuguqulwa nokusetyenziswa, kwaye amanzi amdaka afanelekileyo abandakanya ikakhulu imiba emithathu: amanzi amdaka acokisiweyo, amanzi amdaka afakwa ngamalahle kunye namanzi amdaka anyibilikisa amalahle. Amalungu omgangatho wamanzi amdaka antsonkothile, ngakumbi umxholo ophezulu we-COD, i-ammonia nitrogen, izinto ze-phenolic, kwaye ngaxeshanye iqulethe i-fluoride, i-thiocyanide kunye nezinye izinto eziyityhefu. Ishishini lemichiza yamalahle linosetyenziso olukhulu lwamanzi, kunye noxinzelelo olukhulu lwamanzi amdaka. Uphuhliso olukhulu nolukhawulezayo lweshishini lemichiza yamalahle lizise iingxaki ezibalulekileyo zokusingqongileyo, kwaye ukunqongophala kobuchwepheshe bokucocwa kwamanzi amdaka kuye kwaba yinto ebalulekileyo ethintela uphuhliso olongezelelweyo.
