Elga Labwater Pou Biofilter Unit EA. The elution of filtration steps into the effluent stream by the action of chlorine ions ads an inhibitory layer that allows the transformation of oxygen free radicals to non-toxic water products such as aerated mud and urine significantly reducing the concentration of these contaminants in drinking water. Imperfections in the ether resulting from the elution of these products into the environment can also greatly impact the safety and reliability of lab water systems. To protect against this Elga Labwater developed the pre-filtration stage of the elution process. The initial mixing of the incoming water with the pre-filtration stage ensures that only one chemical is absorbed onto the surface of the water before any reactions can occur. This feature allows the pre-treatment stage to be precisely and safely performed once the desired level of contamination has been attained. There is then an additional phase of elution through the activated carbon layer. The resulting mixture passes through the bag and into the medium further reducing the volume of material that must be filtered through the bag before it reaches the user.
