Paper industry odour neutralisation

Odour neutralisation at a papermill in the Netherlands: nozzle ringline around the biofilter (1200 m³/h) and in the sludge thickening room (fogging ventilator).

In the paper industry there are several areas which need close attention for odor control. Off-gas stacks contain low odor levels but high volumes of air. The waste water treatment is often confronted with varying levels of COD causing the treatment plant to having to deal with intermittant odour nuisance. The paper pulp concentration proces will have to deal with high levels of H2S causing corrosion and ambient odor problems in the processing facility. For all of the above issues Lenntech has developed appropriate solutions targetting on neutralising the smell of the odour.
