Abstract:
1. A method for mixing chemical additives into contaminated liquids, comprising the steps of: providing a liquid conduit having a flow path with a cross-sectional flow path area; positioning at least one vibratable element within the liquid conduit, such that the outer periphery of the at least one vibratable element is in close proximity to an inner wall of the conduit such that the liquid is forced to flow around the at least one vibratable element, the at least one vibratable element being a coiled helix disposed around a rigid central support to reduce the cross-sectional flow path area of the liquid conduit, the rigid central support having a first end and an opposed second end and being secured to the liquid conduit and the coiled helix having a first attachment point attached to the first end of the rigid central support and a second attachment point attached to the second end of the rigid central support; introducing a treatment additive into a contaminated liquid upstream of the vibratable element, the treatment additive selected to interact chemically with the contaminants in the liquid; and directing the liquid through the conduit, whereby the flow of the liquid in proximity to the at least one vibratable element causes the element to vibrate and mix the liquid and the additive.
