WST Settling Tanks

The WST Series Settling Tanks are designed to remove suspended solids from wastewater generated by vibratory finishing and other mass finishing operations. By allowing solids to naturally settle out of process water, these tanks provide a simple and cost-effective method for clarifying water before it is discharged or recirculated back into the finishing process.

In many finishing operations, compounds, fines from media, and metal particles accumulate in the process water. Without treatment, this contamination can affect finishing consistency, increase maintenance, and lead to wastewater disposal challenges. The WST Series provides an efficient first step in wastewater management by separating solids through controlled settling and staged overflow.

Constructed with durable industrial materials and designed for a compact footprint, WST tanks integrate easily with existing finishing systems. Their internal weir and baffle configurations slow water flow and encourage suspended solids to drop out of solution, producing cleaner water that can either be reused in the process or sent to further filtration.

For operations looking to improve water quality, reduce waste disposal costs, and extend compound life, the WST Series offers a practical and dependable solution.

Key Features

• Durable carbon steel or stainless steel construction
• Compact footprint and low-profile design for easy installation
• Sloped tank floor with outlet for simplified sludge removal
• Internal weirs and baffles to promote efficient solids separation
• Available in multiple capacities to match system requirements
• Custom configurations available for specialized applications
• Optional water and compound automation systems
• Optional oil skimmer and flow meter integration
• Optional additional upper tray for faster, double separation, and easier to clean sludge (Model WST-54-D)

Applications

WST Series Settling Tanks are commonly used in industries where vibratory finishing, deburring, or surface preparation processes generate wastewater containing fine solids.

Typical applications include:

• Vibratory finishing systems
• Deburring and edge-radiusing operations
• Metal polishing processes
• Burnishing applications
• General mass finishing operations

By clarifying process water before reuse or discharge, settling tanks help maintain consistent finishing performance while reducing environmental impact and operating costs.

Available Models

Optional Paper Bed Filtration (Model WST-FB-5)

For applications requiring a higher level of water clarity, WST systems can be integrated with automatic paper bed filtration. These systems continuously remove fine particles from process water using disposable filter media.

Features of paper bed filtration include:

• Automatic filter bed advancement as media loads with solids
• Stainless steel clean water tank with two weirs and drain connections
• Sludge collection box for captured solids and used filter media
• Optional float valve for automatic water replenishment
• Optional metering pump for controlled compound addition

When combined with settling tanks, paper bed filtration provides a complete solution for wastewater clarification, helping maintain consistent finishing performance while minimizing water consumption and disposal costs.
