The product Ydro 20 is a specialized product which has been formulated to treat sewer grid and collection systems. It cleans out the pipings, pumping stations and manholes, eliminates rising grid odors and decomposes the wastewater organic matter before it reaches the treatment plant which then requires less effort and energy to be treated. Basic parameters such as BOD, COD, SS etc. are reduced by at least 60% up to 90% while treated with Ydro 20 within the sewer grid. This reduction strictly depends on the length and the design of the sewer system and the initial wastewater parameters. Furthermore, when industrial wastewater is added to the sewer grid, the product can be customized and formulated according to the specifications and even added within the pre-treatment of each industry.
