Corn starch based flocculation aid for water treatment. Zero toxicity, biodegradable, ecofriendly.
Greenfloc flocculants are recommended for use in drinking water treatment technologies and biotechnologies, where their non toxic character plays an important role.
Flocculants are generally used for the removal of suspended solid particles from water. Solved materials need to be precipitated before the application of flocculants for removal. In technologies and equipments designed for the removal of suspended solid particles (clarification, flocculation, sedimentation, flotation, filtration) the flocculants connect to solid particles and exit with the sludge.
The above technologies already use flocculants, but these are synthetic polymers produced from oil or natural gas. Synthetic flocculants can be toxic (especially acryl-amide derivatives, while those derived from allyl-amine and ethylene-oxide are less so), and they are non-degradable, or degrade into toxic wastes. This is why starch based flocculants make a perfect substitute for these synthetic products with a similar dosage of 0,2-1,0 ppm.
With the use of Greenfloc flocculants no toxic or contaminating material is added to drinking water or biotechnological liquid phase. Although less important, it can be advantageous in the case of waste water treatment, too.
Greenfloc flocculants remaining in the sludge degrade in 1-2 weeks producing 99% water and carbon-dioxide. It does not however contribute to the green house effect as the amount of carbon-dioxide produced during the degradation of starch is equal to the amount of carbon dioxide taken up by the plant (which is the source of the starch) during its growth.
Greenfloc products contain a small amount (approximately 1%) of phosphorus. Phosphorus input in the case of drinking water production is 1-5 ppb, but less than 5% of that gets into the clean water (it is under the measuring limit value).
