Reuse resources with the auto strainer and reduce maintenance frequency!

We received a consultation from the Manufacturing Technology Department of a paper company regarding a section of the production line that requires showering. They were previously using a strainer (for washing) to circulate water, but now they are using it as disposable, leading to a significant increase in water usage, which has become a problem for them. 1. When using circulating water, dirty water frequently clogged the shower nozzles, which number in the hundreds, requiring frequent cleaning and replacement. 2. As a countermeasure, they used an auto strainer to reduce nozzle clogging, but the maintenance of the strainer was quite burdensome. 3. To reduce strainer maintenance, they increased the mesh size of the filter, but this led to frequent clogging of the shower nozzles, creating a vicious cycle that made cleaning more labor-intensive. Ultimately, they gave up on using circulating water and resorted to disposables, increasing their usage. They want to find a way to reduce waste of water resources.

basic information

We proposed an automatic strainer made by Asahi Machinery with the aim of minimizing clogging of the shower nozzle even when using circulating water, and reducing maintenance of the auto strainer to a minimum. 1. The automatic backwashing type automatically resolves filter clogging, saving effort. 2. During operation (filtration), it allows for filter cleaning (clogging resolution) and automatic drainage without reducing the flow rate of the passing water. 3. For measures against shower nozzle clogging, a variety of mesh types can be used to determine the particle size passing through the filter, allowing for high precision. 4. The filter is durable and resistant to breakage. 5. Maintenance tasks such as filter removal, cleaning, and reassembly are infrequent and can be completed with simple operations. 6. The automatic backwashing of the filter allows for both differential pressure and time to be set as desired. 7. The filter is not a single drum type but is divided into multiple elements, making disassembly and cleaning easy with only simple tools.
