Using A Walnut Shell Filter As An RO Protection Filter

The purity of boiler feed water can be a critical part of the manufacturing process. This water needs to be free from contaminants in order for the boiler to operate correctly, without frequent shutdown for maintenance.

For this reason, a membrane filtration train is frequently used. Unfortunately, the exposure of plant water to the manufacturing process means that the feed water can be contaminated with both high levels of oils and solid material.

Frequently, the membrane filtration will need an upstream filter, to extend the life of the filters and protect membranes.

The STiR walnut shell filter was selected by a global tire manufacturer to solve these issues related to its’ membrane filtration train.

Their train included reverse osmosis and nanofiltration, and was made unviable because of high levels of oil in its’ boiler feed water. Oil levels were so high the train was taken offline until a solution could be found, and the recirculated water could not be used in the boiler.

Walnut shell media was selected because of its’ ability to remove free oils and greases without causing damage to the media bed.

You see, sand filters and carbon filters may blind prematurely when exposed to free oils, necessitating frequent bed changes.

Walnut shells catch oil droplets on their surface, which are easily removed during backwash cycles. This means that a walnut shell media bed does not need to be replaced when exposed to oil, and has a lifespan of approximately 20-25 years.

The walnut shell filter protects the RO system and nanofiltration membranes, significantly reducing the oil load to them. The free oil concentration was reduced from as high as 85 ppm to less than 1 ppm. This reduced the frequency of membrane fouling, reducing the total purchasing cost.

It also reduced the maintenance requirement of the membrane filters, while protecting the RO system from oil slugs which had caused it to rapidly foul.

Additionally, water heating costs were reduced, as water could now be sent directly back to the boiler.

How Bag and Cartridge Filters Reduce Disposal Cost

Bag and Cartridge Wastewater Filters Can Help You Save Money

Water filtration can greatly reduce your waste disposal costs. How? When suspended solids are removed fromyour waste water, in many cases, it can simply be disposed of to a sewer system.

However, levels higher than allowed can incur fines, and even force the hauling of water off-site for disposal. Even more savings can be achieved with the use of pleated bags.

Seriously, 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.

Bag and Cartridge Filters for a Variety of Projects

However, we do more than simply offer wastewater filters. Filtra-Systems carries a wide line of bag and cartridge housings and filters providing you the flexibility needed for your industrial water filtration challenges.

We stock activated carbon filter bags, oil absorption bags, nylon monofilament mesh, polyester and polypropylene. Cartridges are available in polyester, polypropylene, and nylon and come in a wide variety of micron sizes.

The reality is, bag and cartridge filter products are ideal for any number of different water filtration systems.

These filters can handle a range of operating temperatures and are designed for operation near-freezing to up to 338 degrees Fahrenheit.

Common Pitfalls of Poorly Designed Coolant Filtration Systems

Coolant filtration systems are essential for any mechanized production.

Filtering coolant eliminates small particles from the fluid, including little pieces of metal that can cause problems with pumps, nozzles, and part cleanliness if not removed.

However, if designed improperly, coolant filtration systems can cause serious problems for your other systems and the workspace.

Keep reading and discover some common pitfalls of some systems, followed by Filtra-Systems’ solutions to some of these problems.

Common Filtration Pitfalls

One potential pitfall of poorly designed coolant filtration solutions is their location in a building.

Some coolant filtration systems require massive trenches or pits to accommodate them. Once the position of the trench has been established, the location of the filtration system is locked.

Conversely, the location of all other equipment in the plant is locked by the positioning of this fluid.

Since the piping for coolant also takes up space, it is frequently placed under the work floor, in trenches. Again, the location of cutting tools is limited by its proximity to the trenches.

Pumps must also be sized to pull coolant from the tool to the coolant system, and sent back to the tool at the correct temperature,  flow and pressure.

Without taking these items into consideration, the whole workspace may need to be remodeled, costing you time and resources.

Filtra-Systems Solutions

Filtra-Systems works with you from setup to installation to ensure that all customized equipment is implemented in the correct way.

We offer two separate solutions for our coolant filtration system.

The first is a drum filter system. Traditionally, this system requires a sloped trench in the workplace, making it imperative to plan the location of the trench and the surrounding equipment. A location for a central pit is also needed.

More common now are Hydro-Vac Central Coolant Filtration Systems. These centrally located systems are placed on the plant floor, instead of in trenches.

Clients have the freedom to place this unit wherever it is best suited, with other materials and machinery already in place. This also provides the freedom to make adjustments once the plant is up and running.

Both of these systems are designed and constructed with great care to ensure the system works according to your company’s specifications.

Bag Filter Magnetic Inserts

Did you know the buildup of ferrous material poses a serious risk to not only coolant filtration systems but to the quality of products produced by a manufacturer?

This unwanted material can damage cutting tools and compromise the quality of finished parts.

Many companies in a variety of industries use bag filter systems to help eliminate this material from their operations.  While bag filters are a great first step in combatting this problem, magnetic inserts offer significant benefits to companies that use bag filters in their factories.

Magnetic Inserts For Improved Performance

Magnetic inserts can improve the lifespan and effectiveness of bag filters.  A typical bag filter system would use just the bags to remove material from the coolant.

Unfortunately, bags have a limit to the size of particles they can remove (bags that are sized too tightly will remove important coolant additives in addition to waste).

On the other hand, magnetic bars do not suffer from this deficiency.  These bars are able to remove magnetic particles that would otherwise pass through the pores of bags.

To remove even the smallest particles, the flow should be limited so that the fluid has the greatest possible contact time with the magnets.  To maximize fluid contact time, the system should always operate with a laminar flow.

Less Maintenance & Longer Lifespan

Bag filter systems that do not take advantage of magnetic bars solely rely on the bag to filter out ferrous material.

Naturally, bags that have reached the end of their useful life have to be replaced by plant personnel to complete the changeover.

The fact is, magnetic inserts increase the longevity of the bags by removing particulate before it even contacts the bag.

As a result, bags last longer, which directly translates to fewer man-hours that will be spent changing bags.

Cleaning the magnets is itself simple as well.  When bags eventually plug, simply removing the magnet from its frame and wiping it off is all that’s needed to properly maintain them.

Our magnets have an endless life, meaning that they do not need to be replaced over the life of the product.

Let’s talk and see how adding magnetic inserts to your bag filters can save you time, media and headaches. Call now 248-427-9090.

How To Size A Filter Press

One of the most common questions we receive from you typically relates to the filter sizing process for our filter presses.

Automatic Filter Presses have proven themselves to be incredibly versatile and have a wide variety of industrial applications.  These filters are important parts of the manufacturing process for thousands of our customers around the world, in a multitude of industries.

From mineral processing at mines to municipal waste to biodiesel production, filter presses have proven themselves useful over decades of use.

Excellence Through Testing

You see, testing is the most important part of the sizing process, which we do prior to the design phase.

Properly sizing a filter press is accomplished by testing product slurries using a direct representation of the full scale filter.

This simple step has been incredibly useful in eliminating many future problems, including wasteful spending on overly large equipment, as well as production issues associated with undersized equipment.

The first piece of information our team of engineers needs when sizing a filter press is the mass of dry solids in the system.

A representative sample is needed to find the dry solid mass in slurry.  We first weigh the sample and place it in an oven to dry.  When all of the water has evaporated, we reweigh the sample. The difference in masses tells us how much water was in the sample and the ratio of solids to water.

Running a filtration test allows us to determine the time a filter will take to run one cycle and the amount of slurry the filter is able to efficiently process.

Testing helps to plan ahead and deliver the best-finished system to you and your team.  We have bench scale Verti-Press tower filter presses that are used to size filters for new applications.

Cake conditions and cycle times are optimized so that the correct press size (measured in filtration area) can be implemented.

This testing process allows the team to learn all of the wet and dry cake characteristics, and the cake thickness limits prior to production.  If needed, cake wash water volumes and cycle times may also be analyzed to prove solids purity.

This thorough testing process allows us to achieve excellence and minimize problems that can occur on site.

The bench-scale Verti-Press sizes a full-scale unit by using a simple equation to scale up.  The common formula to do this is:

(m_b)/[(A_b)*(t_b)/60] = (m ̇_f)/(A_f)


m_b = dry mass of bench scale filter cake (lb)
A_b = area of bench scale filter press (ft3)
t_b = time of test cycle (minutes)
m ̇_f = dry mass to be processed (lb/hr)
A_f = area of full scale filter press (ft3)

Different types of media may also be investigated in order to find the one most suitable for the job.  The best filter belt to use will be tight enough that there is no particulate in the filtrate and will be rugged enough to last for many cycles.
