Abstract

Przedmiotem zgłoszenia jest preparat bentonitowy do poprawy sedymentacji osadu czynnego wykorzystywanego do biologicznego oczyszczania ścieków, charakteryzuje się tym, że zawiera ił bentonitowy o wysokiej dyspersyjności, przy czym za preparat o wysokiej dyspersyjności uznaje się preparat, którego wodna zawiesina o stężeniu 200 g/l uzyskana poprzez mieszanie przez 5 minut za pomocą mieszadła obrotowego z prędkością 11000 obr/min posiada lepkość o wartości co najmniej 78 cP, mierzoną reometrem obrotowym o współosiowych cylindrach typu Fann dla 300 obr/min. Zgłoszenie obejmuje też sposób zastosowania przedmiotowego preparatu oraz jego wytwarzania.The subject of the application is a bentonite preparation for improving the sedimentation of the activated sludge used for biological wastewater treatment, characterized by the fact that it contains bentonite clay with high dispersibility, the preparation with a high dispersion with a concentration of 200 g / l obtained by mixing for 5 minutes with a rotary mixer at a speed of 11000 rpm has a viscosity of at least 78 cP, measured with a rotary rheometer with Fann coaxial cylinders for 300 rpm. The notification also includes the method of using the preparation and its preparation.
