Sažetak

Mogućnost da se ekstrakti semena pasulja (Phaseolus vulgaris), bagrema (Robinia pseudoacacia), rogača (Ceratonia siliqua) i bagremca (Amorpha fruticosa) primene kao prirodni koagulanti ispitivana je na sintetički mutnoj vodi. Ta voda je pripremana dodatkom kaolina u vodovodsku vodu, neposredno pre izvođenja ogleda. Aktivne komponente su ekstrahovane destilovanom vodom iz samlevenog semena. Efikasnost koagulacije ovako dobijenim ekstraktima semena je ispitivana standardnim džar testom u vodi različite početne mutnoće. Ispitivanje ovih prirodnih koagulanata je potvrdilo njihovu pozitivnu koagulacionu aktivnost. Od svih ispitivanih seme na, ekstrakt semena Ceratonia siliqua se pokazao kao najefikasniji koagulant za obradu vode. Doza ovog koagulanta od 20 mg/l pokazala je koagulacionu aktivnost od 100% za bistrenje vode početne mutnoće 17,5 NTU.
