Brewing

The brewing industry uses bag filters to separate grains from sugars, remove proteins from slowing the fermentation process, and also remove any unwanted solids prior to bottling. This requires different bags, as the tighter bags used towards the end of the process can have adverse effects if used in early stages.

Mining and Chemical

Bag filters used in these industries must be stainless steel, and frequently carry an ASME stamp. The filtration process must meet stringent regulations, and frequently must be capable of filtering sub-micron particles.

Water and Wastewater Purification

To remove contaminants from water, bag filters along with other purification methods, such as the use of activated carbon or reverse osmosis, are frequently used. Filtering wastewater for reuse means having the capacity to eliminate all types and sizes of contaminants to meet regulations and ensure safety. Industrial bag filters are used to filter water according to the type and size of particles that are in the water.

How Bag and Cartridge Filters Reduce Disposal Cost

Filtra-Systems uses some of the most advanced methods and technologies when it comes to implementing bag and cartridge filters as waste water filters in an industrial setting. With more than three decades of experience in designing, installing, and maintaining water filtration systems, we can provide your organization with the most reliable waste water filters. The high efficiencies of our bag and cartridge filters can help minimize your disposal costs.

Our Waste Water Filters Can Help You Save Money

The filtration of water can greatly reduce a company’s waste disposal costs. If suspended solids are removed from water, in many cases in can simply be disposed of to a sewer system. Levels higher than allowed can incur fines, and even necessitate the hauling of water off-site for disposal.

Even further savings can be achieved through the use of pleated bags. In industries where the filter medium is treated as a hazardous waste (i.e. frac water), the minimization of media to be disposed of is paramount. Pleated bags have a much greater surface area than standard bags, yet fit into the same housing. This allows for greater contaminant removal in a single piece of media. Pleated bags can remove up to 10X the contaminants as standard bags.

Industrial Water Filtration Solutions For Your Industry

Not all industries require the same industrial water filtration system, so Filtra-Systems provides a wide range of products, as well as customized solutions, for many different industries and needs. Some of our solutions include industrial process water systems, wastewater solutions, groundwater solutions, and units for cooling water. Whatever your industry’s needs, we provide systems to efficiently filter out contaminants and particulate.

Industrial Process and Wastewater Solutions

The STiR Walnut Shell Media filter provides solutions for both process water and wastewater. This system is aimed at reusing water, which has both an economical and environmental impact. This system uses a walnut shell media, which is adept at removing both total suspended solids (TSS) and oils from water, while also minimizing the amount of backwash water that is required. The STiR typically backwashes with less than 0.5% of the total water throughput, and in most cases clean water is not required for a backwash.

Groundwater and Cooling Water Systems

Cooling water systems frequently employ either walnut shell filters or bag filters to remove several different types of contaminants. Clean water can be sent back to the cooling source, and water is reused. Groundwater systems include applications where runoff water needs to be filtered. Bag filters are also frequently used, especially in situations where constant filtration is not needed (eg rainwater causes liquid levels to rise, and require filtration). Many different bags are available, and each bag has different properties for different applications. The bag material can be varied for changing liquid stream compositions, such as the addition of oil. Different micron ratings are available for different removal efficiencies. We provide systems which are easily maintained and flexible to your needs.

Overall, each business needs its own, individually selected solution to filter their water. Filtra-Systems is there to provide these different options for each companies preferred filtration system. These products will help your project as cost effective as possible, and our products stand the test of time so you can keep the same filtration system for many years to come.

Incorporating Bag Filters Into Your Treatment Systems

Deciding on which bag filters to use in your treatment system depends on many factors. For one, it’s important to consider which type of filter housing is necessary for your needs: single or multiple bag housing. Next, you must decide which type of filter bag the project requires.

Bag Filter Housing

The housing of the bag filters should be considered before any purchase is made. This ensures that the bag filters are sized correctly for the water treatment system. The first point to consider is the flow rate that the water needs to be filtered at. If the project calls for a high flow, selecting a multiple bag filter will allow all of the water to be filtered by only using one housing. However, if the project is smaller, it might not require the extra filtration afforded by a multiple bag unit. In this example, a single bag unit would be more appropriate.

The next point to consider is the material of construction of the housing. Industrial water and wastewater projects typically use 304 stainless steel. In applications where oils, coolants, or caustic fluids need to be filtered, carbon steel is much more commonly used. For filtration of acids, and other corrosive materials, 316 stainless steel, or other higher grades of steel are required.

Which Bag Filter To Choose?

Along with the choice of housing for the bag filtration system, selecting the correct filter for the job is essential. Anyone installing a filter system needs to consider the type of liquid to be filtered and the material that needs to be removed.

Starting with what is being filtered, an activated carbon impregnated bag filter is an excellent choice for the removal of heavy metals, VOCs, BOD, and other organic compounds. It is able to adsorb dissolved material from water. If oil needs to be removed from water, an Oil Absorption Bag Filter is the best choice. The multi-layer design increases the chances of oil droplets colliding with and absorbing onto the polypropylene material as the water passes through the bag. Nylon Mesh bags are frequently used in applications where more porous bags are needed (greater than 100 micron).

The two most common materials used in bags are polypropylene, and polyester. To decide which material to select, first consider the liquid being filtered. Polypropylene offers excellent chemical resistance, and is often selected when acids, bases, or water needs to be filtered. Unfortunately, polypropylene swells when it comes into contact with oil, which can prematurely clog the pores of a bag. For this reason, polyester is used when filtering oils, coolants, and solvents. Polyester can also be used for water or weak acids.

To create the perfect filtration system for your project, consider the above suggestions before determining which bag filter you need for your treatment system.
