CB/T497 Marine Filter for Bilge Water and Ballast Water Treatment Systems
Product Spotlights
As a dedicated manufacturer with a focus on marine fluid control solutions since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our specialized CB/T497 Marine Filter. Engineered specifically for the demanding environments of bilge water and ballast water treatment systems, this filter is a critical component for vessel compliance, operational efficiency, and environmental protection. Our commitment to quality, backed by ISO9001 certification, ensures that every unit delivers reliable separation of solids, protecting sensitive pumps, separators, and treatment units downstream. We understand the challenges faced by ship owners and operators, and our filter is designed to offer a robust, low-maintenance solution that contributes to smoother voyages and reduced operational risks.
The core function of our marine filter is to provide effective solid-liquid separation. It is strategically installed within bilge and ballast water lines to capture debris, rust particles, sand, and other contaminants before they can cause damage or clog critical equipment. This pre-filtration is essential for the optimal performance and longevity of oily water separators (OWS), ballast water treatment systems (BWTS), and associated pumps.
Key Product Features & Technical Advantages:
- Robust Construction for Marine Service: The filter housing is fabricated from corrosion-resistant materials such as Stainless Steel 316 or Duplex stainless steel, chosen for their exceptional resistance to saltwater corrosion. For less corrosive applications, carbon steel with protective coatings is available.
- High-Capacity Filtration: Designed with a large dirt-holding capacity in the filter basket, it extends service intervals and reduces the frequency of cleaning, which is crucial for unmanned machinery spaces (UMS) compliance.
- Minimal Pressure Drop: The optimized internal flow path and cleanable mesh design ensure a consistently low pressure drop across the filter, maintaining system efficiency and minimizing pump energy consumption.
- Versatile Installation & Maintenance: Features a top-mounted cover for easy and quick access to the filter basket without requiring the disconnection of pipeline flanges. This design simplifies inspection and cleaning procedures.
- Customizable Configuration: We offer various options to match specific system requirements, including different micron ratings, pressure gauges, differential pressure switches for automatic cleaning initiation, and drain valves.

Frequently Asked Questions (FAQ):
-
Q: What is the primary purpose of this filter on a vessel?
A: Its main role is to act as a pre-filter, removing solid contaminants from bilge water (wastewater in the ship's hull) and ballast water (used for stability) before it enters treatment systems like oily water separators or UV ballast water treatment units, preventing damage and ensuring they function correctly. -
Q: How do I determine the correct micron rating for my application?
A: The ideal micron size depends on the sensitivity of your downstream equipment. We recommend consulting your treatment system manufacturer's specifications. Common ratings are between 100 and 250 microns for general bilge protection. Our technical team can assist you in selecting the most suitable option. -
Q: Is the filter easy to clean and maintain?
A: Yes, it is designed for straightforward maintenance. The top-opening design allows crew to remove the filter basket for manual cleaning without major disassembly. For higher automation, an automatic backwash version is available that cleans itself based on a preset pressure differential. -
Q: What materials are typically used, and how do I choose?
A: The standard housing material is Stainless Steel 316 for superior corrosion resistance in seawater applications. For highly corrosive environments or chlorinated ballast water, Duplex stainless steel is recommended. Carbon steel with epoxy coating can be a cost-effective option for certain bilge applications. -
Q: Are your filters compliant with international maritime regulations?
A: Our filters are designed and manufactured in accordance with the Chinese CB/T497 standard and general principles aligned with IMO (International Maritime Organization) guidelines for machinery and system protection. They are a key component in helping vessels meet the performance standards required by regulations like MARPOL. -
Q: Can you provide filters with specific flange standards or dimensions?
A: Absolutely. We regularly produce filters with ANSI, DIN, JIS, and GB flange standards. Please provide your required nominal size, pressure class, and flange facing details (RF, FF) for an accurate quotation. -
Q: What is your typical lead time for production?
A: Lead times vary based on order quantity, material selection, and customization. For standard specifications, production can often be completed within 4-6 weeks. We provide a confirmed schedule upon order confirmation. -
Q: Do you offer technical support after installation?
A: Yes, we provide comprehensive technical documentation, including installation and maintenance manuals. Our engineering team is available to offer support for installation guidance and troubleshooting if needed.
