Abstract
The invention describes a composition and method for biochemical and mechanical remediation of wastewater or river in which the biomineral is an oxygen releasing material that increases dissolved oxygen, decreases biochemical oxygen demand and chemical oxygen demand and neutralized strong odor through the use of organo-minerals, The claimed composition comprises of dolostone, organic limestone, rocks, petrified wood, clay minerals and zeolites. The claimed composition is utilized either in powder form and applied through dispersion.
Description
water would be allowed to flow to a fourth chamber until day 14. Cumulatively, said . water has received 1.5 kg/m3 treatment of prepared organominerals. Day 14 would mean the opening of effluent pipes for treated wastewater.
In another aspect of invention, organominerals were applied to wastewater from a concentration of 0.5 kg/m? — 1.5 kg/m3.
In another aspect of the invention, the application of the organomineral mixture is proven effective in the treatment of wastewater as shown in the following results.
A. Odor Removal
Odor was determined by five (5) panelist with a keen sense of smell and were determined to be free from cold and allergies. Samples were diluted with odor-free distilled water using varying proportion until they were of the same odor as the standard odor - free distilled water. The number of dilution gives the TON or threshold odor number (TON) determined through stated formula
TON = (Volume of Sample) + (Volume of added odor — free water)
B. Volume of sample
In another aspect, reduction of odor in the wastewater through TON (Threshold Odor Number) was done. The wastewater before remediation generally had a foul or rotten egg odor with a TON value of 110. The remediation is effective in reducing the odor or wastewater to TON ranging from 1 — 6 only. Higher concentrations of biomineral showed higher % odor reduction. 0.5 — 1.0 kg/m? concentration can reduce odor by 95% while 1.5 kg/m? concentration can reduce odor by as much as 98% after 10 days. The reduction in foul odor can be attributed by the application of biomineral which enhances the growth of bacteria and microorganisms present in wastewater. Bacteria and microorganisms then digested the pollutants present that caused the foul odor. In addition, the organominerals significantly increased the amount of oxygen in wastewater thereby promoting aerobic decomposition reaction while limiting anaerobic reaction.
