    wet scrubber for producer of organic soil fertilizer

    Product: Wet scrubbers Sector: Composting

    Multi-stage wet scrubber system

    Client request

    An international producer uses pig manure to produce organic soil fertilizer. They want to expand the production facility. Consequence of the expansion is a higher emission of ammonia and odour. What is the best technique to reduce theses emissions?

    Pompen Pumpen Pumps


    After various meetings it was clear to the client that the multi-stage scrubbing system is the most effective solution for the expansion. In the scrubber the process air is being cleaned efficiently. In the first stage, sulphuric acid is added to the water. Together with the ammonia it forms ammonium sulphate, a high-grade fertilizer which is used to enrich the compost. In the second washing stage, the remaining smell components are washed out of the air by water and an additive.

    The system contains:

    • a double-walled storage tank for indoor installation with double-walled piping
    • a multi-stage scrubber
    • a chimney
    • complete automation (Siemens) of all components


    The water packages of the multi stage scrubber have an extra large surface area and offer a low air resistance at the filter during the cleaning of the air flow. A unique pump technology enables a continuous irrigation of the unit so that it keeps the complete system clean. The pump unit also lowers energy costs. The system, like all products of AEC Systems, is easily accessible and therefore maintenance friendly.

    These are all advantages why the composting plant chose AEC Systems.

    Air flow: 100.000 m3/h
