News - Customer Case: 316L single-cylinder self-cleaning filter helps with online filtration of krill separation water

Project Background

The client is located in Malaysia and is engaged in aquatic product processing-related business. In their production process, after the cooked krill is separated by the horizontal screw centrifuge, a stream of separated water is generated, which needs to be filtered online before the downstream process to remove solid impurities in the water and protect the subsequent pipelines and equipment. Previously, the client used an artificial cleaning method, which had high maintenance frequency and long downtime. Therefore, they hope to introduce a self-cleaning filter with a simple structure and convenient maintenance.

Process requirements

The client clearly defined the on-site process conditions:

• Material: The separated water from the cooked krill after separation by the horizontal screw centrifuge
• Flow rate: 5 cubic meters per hour
• Required filtration accuracy: 5 millimeters
• Installation space: Pipe interface need to match the existing pipelines on site

Based on this, the client put forward several clear requirements for the equipment:

Adopt a single-cylinder drive cleaning method, the cylinder cover with lifting rings for easy maintenance, and the entire machine material should be 316L stainless steel to adapt to seawater and high-salt process water environment.

Solution

According to the customer’s working conditions and the requirements of the drawings, we have customized a JYSEC-200-316L self-cleaning filter unit for them. The main parameter configuration is as follows:

Model: JYSEC-200-316L

Material: 316L stainless steel

Flange: DN50 (in accordance with HG standards), sewage outlet DN32

Design pressure: 1.0 MPa; Design temperature: 90°C

Cylinder diameter: 219 mm

Inlet and outlet form: flowing from top to bottom, with the sewage outlet at the bottom

Surface treatment: Sandblasting

Sealing material: Dianqing

Cylinder cap design: Hanger ring

Cleaning method: Single cylinder drive

Cutter-type net: 316L, precision 5 mm

Configuration description: Does not include control cabinet, discharge valve, pressure sensor. It is customized by the customer according to the on-site system. Before production, we confirmed the dwg drawings with the customer to ensure that the equipment shape, flange specifications, and pipeline layout are consistent with the site, avoiding installation rework.

Key features of the solution

1. Precise matching of flow

The processing flow rate of 5 m³/h corresponds to the actual output of the horizontal screw centrifuge. The selection is not overestimated, avoiding energy and space waste.

2. 316L for high-salt water

The phosph虾 processing water has a high salt content. 316L stainless steel body and cutter-type net provide superior corrosion resistance for long-term operation.

3. Single cylinder drive

Simple structure with 219 mm cylinder diameter. Operation is reliable with few fault points, making daily maintenance easy and regular.

4. Optimized Flow Channel

Top-to-bottom flow with bottom discharge port. Gravity aids impurity settlement, ensuring thorough discharge and reducing screen blockage.

5. 5 mm Cutter-type Net

Wedge-shaped gap filter net is less prone to clogging compared to woven nets. Backwashing effect is excellent for intercepting solid impurities.

6. Thoughtful Maintenance

Cylinder cap includes a hanger ring for easy lifting. Sandblasted surface ensures a uniform appearance suitable for export projects.

7. Flexible Configuration

Allows direct connection to existing control systems, reducing procurement costs and allowing customer self-integration.

Customer feedback

“The customer expressed their approval for the customized approach based on the drawings, believing that confirming the validity of the dwg files before production effectively reduced the risks during on-site installation; the single-cylinder drive structure and the layout for bottom drainage were in line with the customer’s on-site operation habits, and the filtering effect of the 5-millimeter wedge-shaped net met the expectations. After the equipment was put into use, the frequency of manual cleaning significantly decreased, and the operational stability was improved.”

Case Summary

The core of this case lies in “customization based on operating conditions”: from a flow rate of 5 m³/h, a filtration accuracy of 5 millimeters, to 316L material, single-cylinder drive, DN50/DN32 interfaces, and the layout for bottom drainage, each parameter corresponds to the actual needs of the customer’s on-site situation. For scenarios involving solid-containing process water such as aquatic product processing and centrifuge separation water, the JYSEC-200-316L self-cleaning filter provides a simple structure, convenient maintenance, and flexible configuration for online filtration.
