Decantorul este alimentat cu ap\u0103 la temperatura de 20\u00b0C care con\u0163ine particule de nisip \u00een suspensie. Particulele de nisip se consider\u0103 a fi sferice, cu diametru variabil \u015fi densitatea de 2650 kg\/m3<\/sup>. Concentra\u0163ia particulelor de nisip \u00een suspensie este de 1 kg nisip\/m3<\/sup> suspensie.
