About this file
This document is a Scope of Work for a small-scale filter press project located in Athens County, specifically for a mine drainage treatment plant and iron pigment facility. The project involves a 320 mm x 320 mm filter press designed to dewater pigment sludge from 3% to 30% solids, which is a critical step in the pigment production process. The filter press has specific technical specifications, including 6 chambers, overall dimensions of 69"L x 31"W x 32"H, an empty weight of 520 pounds, and a filtration area of 8 sq. ft.
The equipment features a manual pump hydraulic closure, polypropylene filter plates with EPDM gaskets, and a sidebar frame constructed of ASTM A36 carbon steel with 304SS side rail caps. The press includes additional features such as a dual air blow/even fill/cake wash manifold made of Schedule 80 PVC, an air-operated diaphragm feed pump, and a UV-resistant aliphatic acrylic polyurethane coating in RAL-5017 Traffic Blue. After dewatering to 30% solids, the pigment will be further dried to 70% solids and subsequently tested for purity and market compatibility.

Scope of work small-scale filter press
We are currently in design phase for a mine drainage treatment plant and iron pigment facility at the Truetown Discharge in Athens County. The 320 mm x 320 mm filter press allows the dewatering of pigment sludge from 3% solids (iron) to 30% solids (iron).
A key step in the pigment production process. Once the pigment is dewatered to 30% via the press it will be further dried to 70% solids and tested for purity and market compatibility.
Equipment Description Plate size: 320 x 320 mm plates Cake Thickness: 32 mm chambers Press Capacity: 0.3 cu. ft.
