In our previous article, “Which Type of Filter Press Is Right for Your Factory?”, we discussed how different filter presses — chamber, membrane, and automatic — serve different industrial needs.
But here’s another important question: How do you know when your old filter press needs an upgrade?
Just like any other industrial equipment, a filter press won’t last forever. Its performance slowly decreases over time, and this can silently affect your production efficiency, water recovery rate, and even final product quality.
So let’s look at the five key signs that tell you it’s time for an upgrade.
If your filtration process used to take 30 minutes but now takes nearly an hour — that’s your first red flag.
As plates, cloths, and hydraulic systems age, filtration resistance increases, causing longer cycles and lower output.
👉 Quick tip: Check for clogged filter cloths or worn seals. If cleaning and maintenance don’t help, an upgrade might be your best move.
When the moisture in your filter cake starts rising, it means your pressing pressure is no longer effective.
Old systems often can’t reach the original high pressure levels (like 2.5 Mpa in modern membrane filter presses), leading to wetter cakes and higher drying costs.
In other words — you’re literally paying more for water!
Every hour of unplanned downtime hurts your productivity.
If your filter press requires constant attention — leaking pipes, broken cloths, unstable hydraulics — it’s not just maintenance; it’s a cost sink.
Modern presses, such as Tianfu Long’s fully automatic filter presses, use upgraded PLC systems and intelligent sensors to reduce manual intervention and improve stability.
So if maintenance is eating up your weekends (and your patience), that’s sign number three.
Still operating your filter press manually?
Today’s smart factories prefer automatic filter press systems with digital controls, real-time monitoring, and safety interlocks.
They not only improve filtration consistency but also reduce human error.
Plus, automation helps in energy optimization — meaning less electricity waste and lower operational costs over time.
This one’s obvious — but often overlooked.
If your company has expanded into new production lines or industries (like food processing, chemicals, or environmental wastewater treatment), your old filter press might not meet the higher throughput or purity demands anymore.
For example, if your chemical plant now handles finer particles or more corrosive materials, switching to a membrane or automatic type with anti-corrosion components can make a huge difference.
Upgrading your filter press doesn’t mean starting from scratch.
Many users of Tianfu Long filter presses appreciate our modular design, which allows partial upgrades — such as switching from manual to PLC control, or replacing chamber plates with membrane ones — without changing the entire system.
That means you can modernize your filtration process step by step, minimizing cost and downtime.
With over 20 years of professional experience, Fujian Province Tianfu Long Environmental Science and Technology Co., Ltd. continues to lead in filter press design, manufacturing, and after-sales service.
Our products are widely used in chemical, ceramic, food, metallurgy, and wastewater treatment industries.
We offer:
Advanced solid-liquid separation solutions
High-efficiency, low-moisture filtration
Full-machine warranty up to 18 months
Professional technical support
When your factory is ready for the next level of productivity and sustainability, Tianfu Long Filter Press will be right there with you.
Your filter press might still “work,” but if you’re noticing longer cycles, wetter cakes, or rising maintenance costs — it’s probably costing you more than you realize.
Upgrading to a modern membrane or automatic filter press can dramatically improve efficiency, lower energy use, and reduce waste.
