Exploring backflush filtering with Croft Filters

Keeping an industrial plant running smoothly is no easy feat.

Whether you’re in the Pharmaceutical, Oil, Gas & Energy, or Food & Beverage industry, many parts of your business need to run correctly at all times. If one thing doesn’t run properly – even something as small as a filter – it can throw your entire production line off balance. According to research conducted by OneServe, downtime is a serious detriment to productivity in the workplace. Around 3% of all working days are lost each year because of downtime, equating to around £31,000 in lost revenue per incident. At Croft we invested in a state-of-the-art laser cutting system in order to produce customised filters for our clients faster in-house, as well as creating more advanced tools to reduce the impact of downtime.

Investing in the fight against downtime

Many of the filtering solutions that our clients rely upon today use in-and-out technology. This simply means that water and other substances move through the filter, allowing for debris and dirt to be captured by a carefully constructed metal cage. These filters work very well for a time, providing the consistency in results that today’s companies need. However, they do eventually need to be removed and cleaned so that the debris captured by the system doesn’t clog the operating mechanisms. Unfortunately, it’s difficult to predict when a filter needs to be removed and maintained. This means that many plants experience unexpected downtime when their system suddenly stops working due to a clog. Thanks to our investment in the new in-house laser cutting machine, Croft Filters can produce backwashing filters, which can keep unplanned downtime to a minimum.

How the backwashing principle works

When a filter clogs, usually the only option is to remove the component from its machine and clean it thoroughly. This means shutting down the entire workflow for a time. For most manufacturers, downtime is the single greatest source of lost production time and income. The biggest expense usually comes from unplanned downtime. Unfortunately, 82% of companies have experienced unexpected disruptions over the last few years. Generally, most companies will know that their filters will eventually need to be cleaned, regardless of their capabilities. However, using our advanced laser cutting service, we can create durable and robust backwashing systems that allow for water to be pumped back through the filter. This form of preventative maintenance shakes up the inside of the filter cage, dislodging clogs, and allowing the machine to operate for longer. The backwashing process means that companies can complete a project before they need to remove and clean the filter. It may even be possible to wait until the end of the production day to perform maintenance, which makes the downtime as inexpensive as possible.

Designing backwash filters

The backwash filters designed by Croft reduce the expensive interruptions that companies encounter when their systems unexpectedly clog and fail. You can extend the longevity of your filter temporarily and schedule your downtime for a more appropriate period. Before investing in the state-of-the-art cutting machine, we had not been able to produce backwash filters, as they require exceptional strength and high-level material cutting. The laser cutting technology allows us to offer high-quality products faster, and to bring more diversity and flexibility to our manufacturing process. More robust materials can be used to protect the filters from being crushed or damaged by the significant pressure of a backwashing system. Our advanced laser cutter can cut through virtually any material, from the thinnest materials to the most durable alloy. This has given us the freedom we need to continue producing incredible bespoke filters for a range of applications.

Services to suit you

In any environment, filters need to be properly maintained, with regular cleaning to remove particulates and debris. However, an effective backwashing filter will allow you to get more time out of your machines and reduce the risk of unplanned downtime. With our help, you can get rid of the costly disruptions that might be hampering your workflow, and make sure that maintenance happens at a time that suits your schedule.
