Process for treating wastewater

A method of treating wastewater and removing suspended solids therefrom comprising:

• a. mixing hydrated calcium hydroxide with bauxite and a carbon source to form a calcium hydroxide based reagent;
• b. mixing the calcium hydroxide based reagent into a slurry;
• c. directing wastewater having suspended solids and other impurities therein into at least one reactor;
• d. continuously feeding the calcium hydroxide based slurry into the reactor and mixing the calcium hydroxide based slurry with the wastewater;
• and
• e. wherein the calcium hydroxide based reagent acts to combine with the suspended solids within the wastewater, causing the suspended solids to settle in the reactor so as to remove suspended solids from the wastewater and generally purify the wastewater.

A method of treating wastewater by removing solids, reducing the concentration of pathogens, killing bacteria, removing ammonia and nitrogen, and removing odor and improving the general color of the wastewater comprising:

• a. mixing hydrated calcium hydroxide with bauxite and activated carbon to form a reagent;
• b. the reagent including, by weight, approximately 80-99% calcium hydroxide, 0.5-10% bauxite, and 0.5-10% activated carbon;
• c. forming the reagent into a slurry;
• d. feeding the formed slurry reagent into a reactor containing wastewater and continuously mixing the slurry reagent with the wastewater;
• e. introducing a flocculating agent in the form of a polymer into the wastewater, independently of the reagent, and mixing the polymer with the wastewater such that solids within the wastewater tend to form flocs and settle to the bottom of the reactor and thereby act to purify the wastewater;
• and
• f. introducing chlorine gas into the wastewater and mixing the chlorine gas with the wastewater such that the chlorine gas reacts with ammonia nitrogen found in the wastewater such that the chlorine gas effectively converts the ammonia and nitrogen to hydrochloric acid and elemental nitrogen.
