  • Belt Filter Press Systems for Sludge Dewatering

    Before sludge enters the press it is chemically conditioned for dewatering with an emulsion polymer flocculant that helps form stronger flocs. After chemical conditioning a transfer pump drops the sludge onto a preliminary dewatering belt where free water molecules separate by gravity and fall into a collection trough.
