Screw Press Sizing Guide: How to Calculate the Right Capacity for Your Plant

Sludge Dewatering Equipment /

Selecting the wrong screw press capacity is one of the most costly mistakes in sludge dewatering design — yet most sizing errors are entirely preventable. This guide presents a 4-step methodology: estimating your daily DS load, converting it to required press throughput, applying the right safety factor for your application, and verifying hydraulic loading. Includes a full worked example, press capacity reference tables, and a guide to the 7 most common sizing mistakes.

Screw Press Sludge Dewatering: Dry Solids Content Benchmark by Industry

Sludge Dewatering Equipment /

The single biggest lever for reducing sludge disposal cost is dry solids content — yet DS benchmarks are rarely published by industry. This guide covers achievable DS ranges for 11 sludge types (municipal, food processing, pulp & paper, pharmaceutical and more), with a polymer selection guide, disposal cost calculator, and a diagnostic table for when performance falls below target.
