Efficient method for removal of aromatic carbons At soil remediation and drainages ground water may be contaminated with mono- and polycyclic hydrocarbons. These components are often present in concentrations which do not allow further processing unless the water is treated. An appropriate solution is required to handle this. Familiar treatment methods apply the use of activated carbon. This generates a downside: after saturation the carbon is to be regenerated or to be wasted. Biological degradation in a continuous moving bed media filter is successfully applied to convert both mono-cyclic and poly-cyclic hydrocarbons into harmless components. The oxygen required for the … Read more

Is direct continuous filtration thé solution to treat surface water?   The straight answer is: no, not always, but sometimes it might be! If it is suitable it is a wonderfully simple process set-up: after feed strainers you apply a continuous sand filter with in inline feed dosing of coagulants. The filter acts as a flocculator and a floc separator, resulting in a stable high quality filtrate.   But how do we know when this is feasible? We tried to offer you some guidance.   For surface water treatment the solids loading to the filter is based upon variable feed … Read more
