Abstract
Effect of Aluminium Sulphate Aging on Coagulation Process for the Prut River Water Treatment
Highlights
The quality of river or reservoir water is commonly characterized by the content of suspended solids, colloidal particles, natural organic matter and other soluble, mostly inorganic compounds, present in different concentrations.when the river or reservoir water is intended for human consumption, an appropriate treatment process is usually considered as necessary to meet the respective drinking water standards
The influence of coagulant aging time on coagulation process performed on model solution The aged aluminium solutions show different coagulation behaviour than that of freshly prepared solutions
The lowest value of residual turbidity in raw water is recorded after 60 minutes of settling, being in limits 0.4 – 1.7 UNT in case of aluminium sulphate solution of 10% and 0.3 – 1.6 UNT in case of aluminium sulphate solution of 25%
Summary
The quality of river or reservoir water is commonly characterized by the content of suspended solids, colloidal particles, natural organic matter and other soluble, mostly inorganic compounds, present in different concentrations.when the river or reservoir water is intended for human consumption, an appropriate treatment process is usually considered as necessary to meet the respective drinking water standards. The aim of presented research was to highlight the influence of the aging of aluminium sulphate solution on the turbidity removal from water. The influence of coagulant aging time on coagulation process performed on model solution The aged aluminium solutions show different coagulation behaviour than that of freshly prepared solutions
