Waste water treatment and decontamination are usually included precipitation, coagulation, flocculation (P/C/F) agents such as alkaline solutions, metal chelating chemicals, and polymeric compounds. Currently, different biological molecules, such as chitin and chitosan, are being used to remove low concentrations of contaminants like metal ions and dyes from waste waters. Our solution is to use animal proteins such as hemoglobin – common by-products of meat industry to coagulate waste water and absorb heavy metals. Our product is being produced from animal blood by simple one-step procedure, has long storage stability and has been proven to be efficient flocculant in a number of laboratory model systems, e.g. kaolin clay suspension, and in real-life applications – rendering, meat processing and municipal waste water treatment facilities. Proteins are also known to be very effective absorption materials for heavy metals by forming chemical bonds with proteins, in which carboxylic acid (–COOH), amine (–NH2 ), and thiol (–SH) functional groups of the amino acids are involved. Our product (Floc-X) is biodegradable natural alternative to currently used flocculants.
