Main Characteristics Mobile, low cost, not compatible with hard blockages Capable of handling hard and viscous materials, large volume of water treatment Small area and water volume, requires more time with larger area Operates in series, expensive treatment agents Compatible with long distance operation, only for pipe work of the same diameter No water, partial removal and not long distance compatible
