Abstract
This invention relates to a biological activator for a septic tank of the type comprising a product in the form of solid particles, which is non-corrosive, non-toxic, finely divided, and of large specific area, comprising a colloidal phase in suspension and a flocculent phase, having a reducing power of mineral origin, its function being to form a support for anaerobic microbial flora in a septic tank in order to increase the bacterial saturation density in a septic tank for an equivalent quantity of nutrients, its specific area being (in m2/g) between about 25 and 66, more particularly between about 35 and 66, and advantageously between about 46 and 60, and a cation exchange capacity (in meq/100 g) between about 9 and 38, more particularly between about 14 and 38, and advantageously between about 24 and 35.
Claims21
A biological activator for a septic tank which activator comprises particles of essentially vitreous materials and kaolinite.
A biological activator for a septic tank which activator comprises in admixture about 87.5% particles of kaolinite and about 12.5% particles of at least one zeolite, and
- wherein the kaolinite particles have:
- (i) a specific area of between about 29 and 35 m2/g;
- (ii) a cation exchange capacity of between about 12 and 16 meq/100 g;
- (iii) a grain size of less than about 16 microns for at least about 91% of the particles;
- (iv) a density in water of between about 2.4 and 3 kg/m3;
- (v) a negative redox potential of about 400 to 600 mV;
- (vi) a pH of between about 6.8 and 7.3;
- and which kaolinite particles further comprise about 2% of Fe2O3;
- about 2000 mg/kg of Cu, and about 4500 mg/kg of Zn;
- and wherein the kaolinite particles have
- (i) a specific area of about 250 m2/g;
- (ii) a cation exchange capacity about 170 meq/100 g;
- (iii) a grain size less than about 180 microns for at least about 95% of the particles;
- (iv) a density in water of about 2.2 kg/m3;
- (v) a pH about 8.87;
- (vi) a positive redox potential;
- and
- wherein the zeolite particles further comprise about 46.5% of SiO2, about 15% of Al2O3, and about 10% of CaO.
