In systems where consistent, high pressure is required, shutting down the system to perform maintenance can be a serious and costly delay. Self-cleaning strainers are used in a number of industrial applications, including power plants, sewage systems, and water treatment plants, to reduce the amount of downtime due to cleaning. These industries and more have found automatic self-cleaning filters useful since they offer continuous flow and save on costly cleaning expenses.
How Automatic Self-Cleaning Strainers Work
Automatic self-cleaning strainers are a motorized strainer that is used to continually remove contaminants and debris from an industrial pipe system. The flow of liquid enters the strainer at the bottom and works its way upwards through the strainer and then out. Any unwanted debris is caught inside the strainer and pushed to the bottom. When the differential pressure reaches a set point the flush valve at the bottom opens and removes the contaminants.
Self-cleaning strainers differ from other strainers in how they are cleaned. Regular strainers require manual cleaning, but self-cleaning strainers do it themselves through tubular backwashing and mechanically cleaning technology, all while allowing the system to continue to work. The filter inside is cleaning in sections, allowing the rest of it to continue working. When one section is done it moves on to the next and so on. Even during the backwashing stage, the flow never stops.
Industries Benefiting from Self-Cleaning Strainers
Automatic self-cleaning filters can be used in a variety of different industries. They can be used to filter fresh, brackish, or salt water, slurries, sticky liquids, and other viscous fluids. With their versatility they provide benefits to many industries.
- Pulp and Paper Industry. Automatic self-cleaning strainers are used to remove and separate the bark and chips to help prevent nozzles from clogging.
- Sewage and Water Treatment Plants. Automatic strainers are used as a secondary strain before the discharge stage and to provide clean service water within the plant.
- Primary Metal Industry. Self-cleaning strainers are used to supply uncontaminated water for quenching and descaling and for blast furnace cooling.
Other industries, such as the process and power industries, use automatic self-cleaning strainers to help protect critical parts in the system such as the pumps, spray nozzles, valves and more.
Benefits of Automatic Self-Cleaning Strainers
Having an automatic self-cleaning strainer offers many benefits to users. Some of the major advantages of self-cleaning strainers include:
- Saving Money. With automatic self-cleaning strainers you require less supplies, such as disposable filter bags, so your cost to operate reduces over time
- Saving Time. Since they automatically clean themselves, you have less maintenance to perform. You also do not need to shut the system down to clean it, which saves time and allows you to continue operation as normal.
- Allowing for continuous flow. With automatic self-cleaning strainers the flow never stops, even during the backwash and cleaning cycles. This is especially helpful in high pressure situations.
