Customer Case: Project for Retrofitting the Circulating Water Filtration System of an Australian Water Treatment Enterprise Customer

2026-04-02

Background

The client is a large water treatment service provider headquartered in Queensland, Australia. It mainly offers solutions for circulating water treatment and reclaimed water reuse to municipal sewage treatment plants, industrial parks, and commercial complexes. As the business scale expanded, the client's original filtration equipment gradually failed to meet the increasing project demands in terms of processing capacity, maintenance efficiency, and operational stability.

Challenges and Requirements

The client needs to intercept suspended solids in the circulating water, cooling water, and pretreatment water at multiple project sites, ensuring the normal operation of subsequent process equipment. The core requirements are as follows:

The filtration accuracy needs to be stable at 100 micrometers, effectively removing silt, suspended particles and biological sludge.
The equipment needs to be capable of operating continuously for 24 hours, with high reliability and low maintenance frequency.
The on-site operators have limited skills, so the equipment should be simple in structure and easy to maintain.
All project sites need to adopt the same equipment model to facilitate spare parts management and personnel training.
The interface should comply with the ANSI standard to facilitate a quick connection with the existing pipeline system.

Solution

In response to the multi-project and large-scale demands of customers, we recommend and provide the JYSF-#2/304 stainless steel single-bag filter. The specific configuration is as follows:

Main Material 304 stainless steel, with sandblasting treatment, featuring excellent corrosion resistance and suitable for humid and outdoor environments.

Structural Form Side-in, side-out. Installation is flexible and can adapt to different on-site pipeline layouts.

Filter Element PE filter bag, 100 microns, fully heat-melt-welded plastic mouth, completely eliminates leakage around the edges.

Monitoring & Emission Inlet/outlet equipped with pressure gauges (NPT); top cover includes vent valve; bottom equipped with drainage valve.

The customer purchased 30 units at one time and deployed them at 6 water treatment project sites, covering various application scenarios such as circulating cooling water filtration, pre-treatment water interception, and reclaimed water reuse.

Implementation Effect

Filtering effect is stable: The 100-micron filter bag effectively intercepts suspended solids, reducing cleaning frequency of subsequent equipment by approximately 40%.

Maintenance efficiency improved: Quick-opening design enables bag replacement without tools. A single maintenance operation only takes 5 minutes.

Operation status visualization: Pressure gauges assist personnel in quickly identifying blockages, preventing unnecessary shutdowns.

Equipment operates reliably: Continuous operation for 8 months with zero leakage or malfunctions across all 30 units.

Operational cost optimization: Unified model reduced spare parts inventory costs by 35% and shortened installation time.

"We chose the JYSF series filters because we were impressed by their simple structure and stable performance. The 30 devices are distributed across multiple project sites, and the uniform model greatly facilitates operation and management. The configuration of pressure gauges and discharge valves is very practical, and the on-site workers have reported that the operation is simple and maintenance is convenient. The manufacturer has also provided adequate guarantees in terms of supply cycle and technical support. We will still give priority to this model for new projects in the future."
