Filter Press Washing Efficiency: Why Your Wash Cycle Costs More Than You Think

The purchase price of a filter press is paid once, but the wash cycle is paid for on every batch. This post explains why two-sided cake geometry limits filter press washing efficiency, what that costs in wash water, cycle time, and labor, and how to measure it before it shapes your next equipment decision.

Filter Press vs. Belt Filter Press vs. Rotary Pressure Filter: Side-by-Side Comparison

Filter press, vacuum belt filter, and rotary pressure filter get compared constantly, and searches for “belt filter press” often blur two different technologies. This post defines each one clearly, compares them on the factors that drive a specification decision, and shows where BHS's testing lab fits into making that call.

The True Cost of Batch Filtration: Downtime, Labor, and Yield Loss

Cycle time and wash consumption only tell part of the story. This post breaks down the labor, unplanned downtime, and yield loss that build up around a batch filter press, why those costs rarely appear in a capital equipment comparison, and how testing puts a real number on them.

.. Plans change. Good equipment lasts. .. Quality process equipment is built to last, and sometimes project plans change before that equipment reaches the end of its useful life, or even before it is ever put into service. Whether a project is canceled, production requirements shift, or equipment was originally purchased to support a temporaryContinue reading

How to Spec a Filtration System for a New Process Line

Specifying a filtration system for a new process line starts long before anyone chooses a technology. This post walks through the process characterization, testing, and validation steps that produce a spec engineers can defend in a capital project review, including what a good test report contains and when pilot testing earns its cost.
