Custom Submerged Drum Filter for High-TSS Applications

Product FAQs: Custom Submerged Drum Filter for High-TSS Applications

Q1: What is a Submerged Drum Filter and how does it work?

A1: A submerged drum filter is a filtration device that operates while partially submerged in the water body. It is typically installed directly within a sump tank or filtration channel. Its working principle relies on gravity (water level difference) from the aquaculture water to drive the flow through the drum. Solid impurities (TSS) in the water are trapped on the inner surface of the drum’s mesh screen. When impurities accumulate to a certain level, the system automatically triggers a backwash, using nozzles to flush the debris into a collection trough for discharge.

Q2: Why is this filter suitable for “High-TSS (Total Suspended Solids)” applications?

A2: A high-TSS environment means the equipment must handle more solid waste and endure greater wear. Our custom design addresses this challenge in the following ways:

• Robust Materials: The main body uses a stainless steel frame and drum for excellent corrosion resistance. For high-wear applications, we can upgrade key components (like the filter mesh and bearings) to 316 stainless steel.
• Reinforced Drive System: We offer optional brand-name motors with reinforced, widened gears and custom waterproof enclosures to ensure stable transmission even in humid, high-load environments.
• Efficient Backwashing: The system supports automatic, high-pressure backwashing linked to level sensors. When high TSS clogs the mesh and increases the water level differential, the high-pressure nozzles activate immediately to clean the screen, ensuring filtration flow is maintained.

Q3: What does “Custom” mean? What parameters can I customize?

A3: Yes, we offer comprehensive customization services. You can customize:

• Filter Precision: The standard mesh pore size is 60-74µm (microns), but this can be adjusted based on your aquaculture species or specific TSS particle size.
• Material Grade: You can select a 304 stainless steel body and upgrade key components to 316 stainless steel to suit seawater or highly corrosive environments.
• Size and Flow Rate: Our engineers will provide one-on-one design services using CAD and 3D modeling based on your existing channels, tank dimensions, or desired processing flow rate.
• Interface Standards: We can pre-fabricate flanges and openings to match European, American, or common Asian pipe standards.
• Electrical Specifications: We support global voltage and frequency adaptation (e.g., 110V/220V/380V; 50Hz/60Hz).

Q4: What are the advantages of a Submerged design compared to a Box-Type filter?

A4: The main advantages of the submerged design lie in its installation flexibility and hydraulic efficiency:

• Simplified Piping: It can be installed directly in a sump or channel, eliminating the need for complex inlet/outlet piping and additional pump head requirements.
• Energy Savings: It is ideal for low-head or gravity-fed systems.
• Space Savings: The installation is flexible and does not occupy extra floor space.
• Easy Retrofitting: It is particularly suitable for upgrading filtration systems in existing ponds or areas with limited space.

Q5: Is this filter difficult to install and maintain?

A5: We provide comprehensive support to simplify installation and maintenance:

• Installation Support: We provide detailed installation manuals and videos. For large-scale projects, we can dispatch engineers for on-site commissioning guidance.
• Ease of Maintenance: The open-frame design (similar to our KK series) allows for direct observation of the drum’s operation and mesh contamination. Components like the filter mesh, seals, and transmission parts are all designed to be quickly replaceable on-site.
• Important Note: The key to a submerged installation is the precise control of the immersion depth and water level, which is essential for optimal filtration performance.

Q6: How does YUTANK guarantee the quality of this custom filter?

A6: We ensure quality through a strict quality control process:

• Certification: We are ISO 9001 certified for quality management.
• Pre-Production Approval: For custom projects, we provide CAD drawings or 3D models for client approval before mass production.
• Final Inspection: Every unit undergoes a final functional and safety inspection before shipment.
• After-Sales Warranty: Core components (like motors and controllers) come with a 1-year warranty, and we provide lifetime remote technical support.

Q7: How can I get a custom proposal and quotation?

A7: Simply contact our sales team and provide as much of the following information as possible:

1. Your water treatment goal (e.g., aquaculture species, main source of TSS).
2. The total water volume or your desired processing flow rate ($m^3/h$).
3. Details of the installation site (e.g., channel dimensions, tank depth, indoor/outdoor).
4. Water type (e.g., freshwater, seawater, high salinity).Our engineers will then provide you with a one-on-one consultation and a detailed equipment configuration plan.
