Screenwashing Project

JBW understood that the client intended to install an in-line screen washing system on Line 1. The equipment was to be installed in the press pit area near the screen incline conveyor. This installation required modifications to the existing conveyor and frame/structure to accommodate the new screen washer frame, accordion coil, and collection trough. Additionally, new piping systems for process supply water, compressed air, and wastewater disposal were necessary.

The scope of services included a one-day site visit for two individuals to perform point cloud scanning of the conveyors in the screen wash area during an outage day. Mechanical design services encompassed evaluating the proposed screenwash equipment location, designing the required conveyor leg and support modifications, designing ultra-high pressure (UHP) piping from the UHP pump to the screenwash unit, designing process water supply piping, and designing a wastewater piping system including a reservoir tank, wastewater pump, pipe routing, and pipe supports to discharge wastewater to the existing wastewater pit. Electrical design services involved cable tray and power cable sizing for 80A and 15A feeds from the MCC room to the equipment supply points.

Deliverables included IFR, IFB, and IFC drawing packages featuring mechanical screen wash plans, sections, and details, mechanical conveyor demo and modification plans, mechanical compressed air, process water, UHP, and wastewater piping plans, electrical general arrangement, electrical device and power cable list, and electrical and mechanical scope of work documents.
