In our previous discussions, we explored how a filter press keeps a factory cleaner and more efficient. But many factory owners still face a practical question: How do you know when your current filtration system is no longer enough?

Just like any piece of industrial equipment, a filter press has a performance limit. When production volume increases, raw materials change, or wastewater becomes more complex, old systems may struggle to keep up.

Drawing from real experiences across ceramics, mining, chemicals, metallurgy, and environmental treatment, Fujian Province Tianfu Long Environmental Science and Technology Co., Ltd. summarizes the most common signs that indicate it’s time to upgrade.

1. Your Sludge Contains Too Much Moisture

If the filter cake still feels wet or heavy after filtration, it means the equipment is not applying enough pressure or the plate technology is outdated.

Common causes include:

• Low-pressure chamber plates

• Aging filter cloth

• Insufficient squeezing force

• Old hydraulic systems

Upgrading to a membrane filter press, such as Tianfu Long’s high-pressure membrane series, effectively reduces moisture content, cuts disposal costs, and increases material recovery.

2. Filtration Cycles Are Getting Longer

A filtration cycle that used to take 30–40 minutes suddenly stretches to over an hour. This usually means:

• The feed concentration changed

• The mud viscosity increased

• The existing press cannot handle new workloads

Longer cycles reduce daily output and increase energy consumption. A modern press with automatic plate pulling, fast-opening mechanisms, and optimized flow paths shortens the process and boosts productivity.

3. More Manual Labor Is Needed Than Before

If your operators spend more time adjusting pressure, cleaning filter cloth, or troubleshooting slurry leakage, this is a strong indication that your system has outgrown manual operation.

Tianfu Long’s intelligent systems offer:

• Automated plate pulling

• Automatic cloth washing

• Real-time pressure control

• PLC + HMI interfaces

By reducing manual intervention, factories achieve safer working conditions and more stable results.

4. Water Quality No Longer Meets Production Needs

When downstream equipment begins clogging or raw material quality becomes unstable, the filtration stage is often the source of the problem.

This typically occurs in:

• Ceramic and kaolin production

• Pigment and chemical plants

• Mineral refining lines

• Food ingredient processing

A modern filter press ensures consistent clarity, allowing factories to maintain product stability and meet increasingly strict industry standards.

5. Your Factory Must Meet New Environmental Regulations

Environmental requirements continue to rise worldwide. If your wastewater or sludge output is no longer compliant, upgrading your filter press is one of the most effective and affordable solutions.

High-pressure membrane filtration reduces:

• Sludge volume

• Residual chemical content

• Water turbidity

• Risk of environmental penalties

With over 20 years of technical experience, Tianfu Long’s equipment is widely used in river sediment treatment, municipal sewage stations, electroplating wastewater, stone polishing wastewater, and more.

A filter press is not simply a machine—it is a key factor in factory efficiency, environmental performance, and long-term cost savings. When any of the five signs above appear, upgrading your filtration system can:

• Improve output

• Lower operational costs

• Strengthen environmental compliance

• Protect downstream equipment

• Support long-term production stability

With proven technology, new materials, and high-standard manufacturing, Tianfu Long continues to help industries achieve cleaner, safer, and more efficient production.
