Filtration/Skimming System for Degreasing Tanks

Product Specifications

Technical details and manufacturing context for Filtration/Skimming System

Definition

A filtration/skimming system is a critical component of industrial degreasing tanks that maintains cleaning solution effectiveness by continuously removing particulate contaminants through filtration and separating floating oils and greases through skimming mechanisms. This dual-function system extends solution life, reduces maintenance frequency, and ensures consistent cleaning quality for metal parts. The system is designed for integration into degreasing tanks used in fabricated metal product manufacturing. It operates by pumping contaminated solution through filter media, such as cartridges, bags, or screens, to trap solid particles. Simultaneously, surface skimmers, which may be belt, disk, or weir types, attract and convey floating oils to collection containers. Some systems integrate both functions in a single unit with shared pumps and controls. Key parameters include flow rate (5–50 m³/h), filtration precision (5–50 µm, ISO 16889), operating temperature (20–80°C), operating pressure (0.2–0.6 MPa), motor power (0.75–5.5 kW), voltage (380–415 V AC, IEC 60038), ingress protection (IP54–IP65, IEC 60529), noise level (60–75 dB(A), ISO 3746), tank connection size (DN25–DN80, ISO 7005), weight (50–200 kg), dimensions (800×600×1200 to 1500×900×1800 mm), and skimmer capacity (10–100 L/h). Materials on file include stainless steel, polypropylene, synthetic filter media, and EPDM rubber seals. These values are reference ranges and must be verified with the legal manufacturer or supplier for specific models and applications. The system is a component, not a standalone machine, and its selection depends on tank volume, turnover rate, and contamination levels. Proper installation and maintenance are essential for optimal performance.

Working Principle

The system operates through two parallel processes: (1) Filtration: contaminated solution is pumped through filter media (cartridges, bags, or screens) that trap solid particles; (2) Skimming: floating oils are removed via surface skimmers (belt, disk, or weir types) that attract and convey oils to collection containers. Some systems integrate both functions in a single unit with shared pumps and controls. The filtration loop continuously recirculates the solution, while the skimmer removes oil that accumulates on the surface. The system is typically controlled by a pump and may include valves and gauges for monitoring. The filter media must be replaced periodically, and the skimmer collection container must be emptied. The system is designed to operate within specified temperature and pressure ranges; exceeding these can degrade seals and reduce efficiency. The system's effectiveness depends on proper sizing relative to the tank volume and contamination load.

Frequently Asked Questions

What is the purpose of a filtration/skimming system in a degreasing tank?

It removes solid particles and floating oils from the cleaning solution, extending solution life and maintaining cleaning quality.

What are the key parameters to consider when selecting this system?

Flow rate, filtration precision, operating temperature and pressure, motor power, voltage, ingress protection, noise level, tank connection size, weight, dimensions, and skimmer capacity. These must match the tank volume and contamination levels.

How often should the filter media be replaced?

Replacement frequency depends on the contamination load and the system's operating hours. Regular monitoring of pressure differential across the filter is recommended; when it exceeds the manufacturer's limit, replacement is needed.

What maintenance signals indicate a problem?

Reduced flow rate, increased pressure drop, poor oil removal, unusual noise, or leaks. If the system operates outside specified temperature or pressure ranges, seals may degrade, requiring inspection.
