productnews New compact plate separators aimed at water applications With the launch of its new CSF model, USFilter's Zimpro Products group has expanded its line-up of inclined plate separators for removing solids from drinking water, industrial water, and filter backwash water. The design of the new model eliminates the need for support beams underneath the lamellar plates, decreasing the basin depth requirement and giving end users more space in which to achieve the required performance. The CSF, or channel supported frameless, plate separator model provides lamellar separation performance at flow rates of one MGD up to 300 MGD. Constructed entirely in stainless steel, the CSF model can handle influent turbidities of five to 500 NTU with anticipated effluent duties as low as 2 NTU or less. Custom-designed units can also be ordered to meet higher duty requirements. In common with all plate separators, the system uses closely spaced parallel plates to achieve separation in water duties. In operation, water enters via an inlet trough and is moved around by channels. These channels support the lamellar plates and are divided into an upper and lower compartment for conveying influent to the plates, where any solids are removed, and effluent to the basin, where it exits the system. This configuration ensures that no solids can re-enter the process. To enhance performance and improve flow control a V-shaped miniature weir arrangement also extends above the water surface between each pair of plates. According to USFilter, the lack of support beams underneath the CSF plate separator should mean that hydraulic control over how water enters and leaves each plate should be improved. Combined with the small footprint of the system, this is the major potential benefit of the new CSF model. Typical projected end uses include raw water sedimentation and backwash water solids removal in potable water treatments. The system can also be utilised as a tertirary wastewater treatment for solids and phosphorus removal.
