Flexible chicane system for liquid-solid separation equipment

A chicane system according to claim wherein said control means comprises a spring applying forces tending to rotate said support rod in a direction forcing said plow portions against said filter belt.

A method of cleaning a chicane system for a filter belt during operation, comprising the steps of:

• rotating a support rod mounted over a filter belt in a first direction to wind flexible leaf spring portions of flow turners about the support rod and to move plow portions of the flow turners depending from free ends of the leaf spring portions in an upstream direction toward the support rod in opposition to slurry flow, while maintaining contact between the plow portions and the filter belt;
• and
• rotating the support rod in a second direction, opposite to the first direction, to partially unwind the leaf spring portions from about the support rod and to move the plow portions back downstream with slurry flow, while maintaining contact between the plow portions and the filter belt.
