With new environmental regulations – and the costs associated with waste disposal – the way INDUSTRIES filter or disposed of, or eliminate waste filter is constantly changing. Selecting filtration equipment is the combined result of many considerations. In addition to removing unwanted material from a fluid stream, filtration method selected must also satisfy other requirements. Installed costs must be weighed against operating costs. the costs of waste management should be considered. Is continuous flow requirement of the application or the filtration equipment can work intermittently? Is employee exposure to the process fluid during filter cleaning or replacement of the problem? These and other factors must be weighed in choosing the right method of filtering for a particular application. Today, more than ever, self-cleaning filters (erasable media) is the best method – and many times what needs to be done – for many reasons. On the cleaned systems, you improve the security of staff, minimizing the workers, and the impact of the workplace for handling liquids. You minimize or eliminate the unlimited expense and inconvenience of replacing the media. You minimize or eliminate an endless and ever-increasing cost and hassle of disposing of the media. You dramatically reduce labor costs at the source, purchase, inventory, transportation, modification and recycling of removable media. You improve the quality and consistency of performance and productivity of the filter. To reduce confusion, when you evaluate various filtering methods / systems, I made a list of questions you might want to consider: Factors that should be considered: When selecting a filter for a specific application, the following criteria must be considered. 1. How large is the volume of the process? What is the rate of flow? 2. Is continuous or batch process? 3. What are the physical characteristics of the solids are removed? How big are the particles? Is the dangerous stuff? Whether the material is removed to be recycled back into the process stream at a different point? 4. What are the costs of waste disposal? How often do bags or cartridges need to be replaced? Can the amount of waste can be reduced or eliminated by switching to another method of filtering? 5. What are the labor and the cost of downtime or the filter cartridge replacement? Can downtime be reduced or eliminated by switching to another method of filtering?
