Investigation of Agricultural Waste as Economical and Effective Bio-Inhibitors for Inhibiting Scaling in Natural Hard Water

In this study, agricultural waste was utilized as new bio-inhibitors to prevent scale formation in hard waters. Aqueous extracts of strawberry and tomato leaves were for reducing the deposits formed on metallic surfaces by Bounouara ground water, which supplies Constantine city Algeria. Anti-scaling properties evaluated chronoamperometry impedancemetry techniques. The effect temperature concentration efficiency assessed. results showed that anti-scaling leaf started at very low 1 ppm, with 31% efficiency, reaching complete scaling inhibition 15 ppm (20ºC), whereas inhibitory noticed 2.5 36% total 20 (20ºC). 40∘C also confirmed, although attained a higher concentration.
