Exploring The Benefits Of Walnut Shell Media Filters

Here at Filtra-Systems, we seek to overcome the limits of regular bed type industrial water filters. In doing so, we leverage a maximum efficiency design for bed regeneration, which is utilized in both the STiR Walnut Shell Filter and Hydromation Deep Bed Filter. The design, construction, and application of these walnut shell filters are a direct result of our company’s attention to customer feedback throughout over thirty years of operation. The Hydromation Walnut Shell Media Filter is now used in hundreds of applications worldwide, in a variety of settings. This post will explain why industries should consider gravitating toward these walnut shell filters.

A Truly Unique System

Hydromation Walnut Shell Media Filters are unique in that their media scrubbing cycle wholly regenerates the filter media during every backwash cycle, through a process that is automatically initiated. This occurs in cases when the filter bed becomes laden with contaminants. The backwash is signaled by an automatic preset time notification or when an increase in filter bed pressure differential is observed.

A Leader In The Chemical And Mining Filtration Fields

Hydromation Walnut Shell Media Filters are field leaders in the mining and chemical industries. These walnut shell filters are deep bed, downflow media filters that are made for oily industrial water filtration. The way that these systems work is as follows:

  • Liquid passes through the media bed
  • All oil and solids are effectively trapped in the bed
  • These oils and solids can easily be backwashed away from the media bed through Filtra-Systems patented rotating media scrubber design
  • Chemicals, surfactants, and air sparging cycles are unnecessary for the backwash to function properly

The Hydromation Walnut Shell Media Filter is a demonstration of the best available technology when it comes to backwashing the media bed. The design of the backwash assembly also allows for the building of large horizontal units that can treat extremely high flow rates.


Hydromation Walnut Shell Media Filters are normally applied to eliminate insoluble hydrocarbons and suspended solids from oily wastewater, plant process water, cooling water, and groundwater in low to high water volume filtration applications. Additionally, these walnut shell filters remove and treat oily residues, suspended solids, and metal hydroxides from industrial water in power generation, chemical, petrochemical, and metalworking applications. Also, Hydromation Walnut Shell Media Filters offer industries the removal of suspended solids and hydrocarbons by increasing the throughput efficiency of conventional grade mixed-media or sand filters.

Customized To Customer Needs

In addition to all of its standard benefits, the Hydromation Walnut Shell Media Filter is entirely customized to customer needs. Regardless of specific on-site requirements, Filtra-Systems provides all clients with the optimal size of filter unit. The Filtra-System support system is also optimally set up, with lab analysis, engineering, installation, and customer support available worldwide.

Why You Should Choose The Verti-Press

By far one of Filtra-Systems’ most highly touted products, the Verti-Press Tower Filter Press is ideal for the dewatering needs of several chemical and industrial mineral companies. Some of the heavy industry companies that use this dewatering filtration system are Kodak and Dofasco. The Verti-Press’ signature characteristic is its vertically stacked columns, allowing for a minimal footprint. Sacrificing footprint does not mean cutting quality, as the Verti-Press produces dry and impressively solid cakes as well as a high wash efficiency.


The Verti-Press features a stacked design that, while simple, will allow companies to use their plant’s vertical space for their operational needs. Tower filter presses take up far less horizontal space than traditional filter presses, meaning that there is more effective plant area. A manufacturing or processing plant inherently comes with a lot of moving parts, both mechanical and human. The implementation of vertical filtration systems such as the Verti-Press can potentially be a key practice for employers looking to minimize safety risks in the workplace.


There are only a small number of moving parts belonging to the Verti-Press, which means that company leaders can save a considerable amount of money on energy and maintenance costs. On top of all that, the individual chambers found in the Verti-Press can easily be isolated, which allows for routine maintenance to be scheduled entirely at the manager’s convenience.


Using a diaphragm, the Verti-Press squeezes the liquid mechanically from solid cakes. Once all of the liquid is pressed out, the remaining dry cakes potentially contain up to 94% solids. Depending on the processing or manufacturing plant in question, a specified dryness might be needed for optimal processes. This is an operational system that allows plants to meet a myriad of requirements at all times.


Through its operation, which combines full automation with high-speed cycling, the Verti-Press Tower Filter Press emerges with an extremely high solids output. Thanks to its design, the Verti-Press can maximize efficiency in manufacturing plants by running a dewatering cycle as low as five minutes.

Already known for delivering exemplary products such as the Hydromation Walnut Shell Media Filter, Filtra-Systems is proud to offer the Verti-Press as a versatile, reliable solution for companies that need an efficient way to wash and dewater slurries. If minimizing footprint and workplace safety risks without compromising yield is a priority, then the Verti-Press would seem like the very best option to commit to. The helpful support staff at Filtra-Systems are ready to provide aid to all inquirers. Filtra-Systems has proven time and again how possible it is to find a cost-effective solution for any company looking to drastically improve their operational efficiency.

Central Machine Tool Coolant Filtration Systems Customized For Your Applications

As a world leader in industrial filtration systems, Filtra-Systems has collaborated with a number of customers during a business run that exceeds 30 years. When it comes to coolant filtration systems  meant for industrial use, there aren’t many more relevant options than Filtra-Systems. By designing and customizing filtration systems over the years, Filtra-Systems has acquired the type of experience that all industrial leaders should gravitate towards when it comes to their coolant filtration needs. Filtra-Systems offers various types of coolant filters, each meant to fit the specific needs of the customer in question. Some of these options include pressure, vacuum, and magnetic filters. Filtra-Systems central machine tool coolant filtration systems are built to offer complete central coolant filtration systems and coolant filters which operate at the required temperature, flow rate, pressure, and clarity.


Traditionally, central coolant filtration systems were placed below the level of the plant floor, in galleries or pits. Back in those days, floor trenches were used to transfer the dirty coolant from the machine tool to the coolant filter, which by necessity was located in a pit, under the sloping trench’s end.


These days, the large majority of central filtration installations are carried out right on the plant floor. This installation method does away with the trench; the pit must also be lined and officially deemed a confined space. In cases where a central coolant filtration system is located on the plant floor, managers have the option to arrange operations based on current needs.


In almost all cases, the design of a central coolant filtration system is entirely dependent on a series of customer specifications, which include the following:

  • Chip Load
  • Pressure
  • Flow Rate
  • Temperature
  • Clarity Requirements
  • Preference for In Floor or Above Floor Design
  • Preference for Vacuum or Pressure Filters
  • Preference for Permanent Media or Disposable Filters
  • Component Specifications

Perhaps the most important thing to keep in mind about Filtra-Systems’ central machine tool coolant filtration systems is that they are entirely customizable. No two coolant filter applications are designed the same; each is built to suit a customer’s specific needs. With thirty patented products designed and built over more than 30 years of business operations, Filtra-Systems understands the myriad needs that come with coolant filtration, and we manufacture our products accordingly.

Choosing The Right Medium For Your Filtration Needs

There are a variety of options when choosing industrial filtration systems. Different implementations are designed to suit particular needs of each industry and each user individually. Filter presses, walnut shell filters, cartridge filters and bag filters are all excellent in their respective uses. Here is a quick guide to deciding the direction that you need to look when deciding on industrial filtration systems.

Filter presses are designed to remove water from the solids, where typically industrial water treatment equipment is made to do just the opposite. Filter presses are ideal for any filtration application where a substantial amount of material needs to be removed so that the more conventional filtration method can then be applied. A filter press operates by using pressurized air or a water-filled diaphragm on a slurry mixture which pushes out the water. The remaining “filter cake” is then either disposed of, or further processed.

A bed filter uses a bed of filter material to remove contaminants. Material is gathered through the bed by taking a tortuous path, allowing large amounts of material to be collected before the filter plugs. A backwash cycle initiated once the medium is saturated with contaminants. The bed is fluidized, and waste is removed. The reuse of the filtration medium significantly decreases waste associated with the process.

Another option for your industrial filtration systems are cartridge filters. These are disposable and replaceable self-contained filtration units. They are made of a central perforated core that is wrapped in layers of filtration material. Inlet water is pumped through the filter core and passes through the walls of the filter. The contaminants are filtered through the depth of the filter cartridge. These are typically used in applications where high purity water is absolutely required. There is a wide range of treatment solutions available, and we can help you find the right fit for your particular need.

Reducing Costs With Industrial Water Filtration

One of the ways that a Filtra-Systems industrial water filter can benefit your business is by reducing operating costs. Our wastewater filters offer many benefits that will not only improve your process but also keep your budget intact. When wastewater is filtered, it not only can reduce costs for the company, but it can be reused and therefore less water must be introduced to the system. Water continues to be a limited resource, and costs for clean water can be very high.

Recirculating wastewater without proper cleaning is never recommended. Typically a bag filter, cartridge filter, or walnut shell filter is used. Depending on what is in the wastewater, an industrial water filter can be designed to remove more or fewer solids. In a case where the wastewater has a large amount of solid material in it, a clarifier or centrifuge may be the most effective first step. The last step of the industrial water filtration process can be the implementation of reverse osmosis, to remove all dissolved material from the water. By managing your wastewater and reusing it in a contaminant free method, businesses can operate without having to worry about the increasing costs of fresh water.
