You may already know that food and beverage processing creates complex liquids that require specialized steps for filtration. Typically, the first step is removing larger particles and sediment. Whether the beverage is raw juice, fermented wine, beer or even spring water, it carries sediment and particulates that must be removed in order to create products that are both flavorful and safe for consumption.
Nearly all clarification filtration applications are performed using depth filtration media. Cartridge filters, for example, use two forms of depth media. The standard depth filter is a self-supporting tube made with a polymer (usually polypropylene), and the tube is formed using the melt-blown or nano-spun process. The other form of cartridge depth filter uses pleated flat sheet media. These are typically made with polypropylene or fiberglass.
It’s not uncommon for custom filtration systems to be designed for new applications and to solve challenges in a manufacturer’s existing process(es). As one of the leading Donaldson filter distributors in VA, we will work with you to design, build and install a system that is cost-effective and meets your needs for excellent beverage filtration. Contact us or visit our page on industrial process filters or Donaldson’s new Lifetec® process filters for more information.
The terms “oil interceptor” and “oil water separator” are often used interchangeably. However, these units are very different.
Oil interceptors are designed for use in drain lines where oils, sediment and other liquids are intercepted. They are usually steel, fiberglass or poly boxes, and include a baffle plate (designed to restrain the flow of a fluid), a solids bucket, and a separation area. As the water enters the interceptor, the baffle plate then diffuses the flow, which reduces the turbulence of the incoming water. Depending on the flow of the water, some debris and sludge are stopped by the baffle plate and collected in the solids bucket.
A low flow rate and low turbulence allows the oils to rise to the surface of the water through the interceptor, thus producing water that is relatively oil-free for discharge.
Oil Water Separators
Oil water separators are used in applications where there is a potential for a higher volume of water and oil (industrial wash operations, military installations, etc.), as they have a much more sophisticated design. An oil water separator is a tank containing an inlet compartment, baffles system, sludge chamber, separation chamber, and clean water outlet chamber. When water enters the inlet compartment, the oil separation process begins and solids drop out. The water passes through coalescing media, removing essentially all free and dispersed emulsified oils to an effluent concentration of less than 5 ppm.
Due to this design, oil water separators in North Carolina are associated with enhanced efficiency. In comparison to oil interceptors, significantly smaller units are needed for higher volume applications.
Permanent and semi-permanent models of air filters can be cleaned as a regular part of HVAC system maintenance, and then reinserted to the unit for continuous use. However, disposable filters simply don’t work the same way. Despite an urge you may have to save money, we have several reasons why re-using disposable industrial air filters in Richmond, VA isn’t a good idea.
They Aren’t Designed to Get Wet
The only air filters that are meant to be washed and re-used are made from materials than can get wet and dry again without forming mold or mildew. Because mold is an obvious IAQ issue, a moldy filter is the last thing you’ll want to put in your HVAC system.
They Can Get Damaged
While cleaning a disposable HVAC filter with a vacuum or your hands may seem like an easy way to conserve resources, a filter can also be damaged if it’s handled this way. If you tear a hole in the fibers or loosen their density, your air filter will simply not work as well as before.
Even Vacuuming Isn’t Effective
While using a vacuum may make the filter appear cleaner, particles of dirt and dust are still trapped within the layers of material. Even if you keep the fibers intact while you clean the filter, a vacuum simply isn’t enough to get it clean again.
Filters keep the hydraulic fluids in your unit clean, and prevent clogs and abrasion that can damage equipment performance and cause the failure of various parts. By changing filters regularly, you can avoid nasty surprises and system failures.
However, if you change your hydraulic filters too early, you may be wasting money on unnecessary filter changes. On the other hand, waiting too long to change them can reduce the lifespan of every component in the hydraulic system.
Overall, you can expect the best bang for your buck by changing hydraulic filters when they’ve reached their dirt-holding capacity, but before the bypass valve opens. This will require a mechanism to monitor the restriction to flow (pressure drop) across the filter element, and then alert you when this point has been reached. Also, monitoring the filter elements in a hydraulic system continuously can provide valuable insight regarding the performance of the filter, as well as the condition of the system. Hydraulic filter suppliers in VA know that with an early warning of potential issues such as component failures and element rapture, you could save a significant amount of money.
If you would prefer a simpler method, refer to your machine’s gauges to tell you when filters need cleaning. However, you should also note the cleaning intervals recommended by the filter manufacturer and use them to create a filter maintenance schedule.
Unfortunately, not all manufacturing facilities have yet recognized the benefits of optimized filtration for process water. This is likely because installing a filtration system may be difficult to justify when budgets are especially tight. However, recognizing key cost factors can easily justify the investment of an up-to-date filtration system.
When exploring options for water treatment filtration, there is a growing area of concern regarding water conservancy and water supply. When combined with an increased emphasis on reducing waste, it is important that all industries determine if it is time to evaluate newer filtration technology. Actually, the cost savings earned from a new system may surprise you.
There are two primary methods: Using equipment that requires less fresh water, or reusing water when the amount used is mandated by the process requirement. With this trend, you will notice reduced costs for the purchase and treatment of fresh water, heating process streams, and waste treatment.
In addition to minimizing overall maintenance costs, other factors include labor costs, the potential costs of lost production, conversion, and recovery of valuable products during scheduled and unscheduled downtime. While this may seem overwhelming, there are a few easy ways to determine whether your current filtration system needs an update.

Because windows and doors are generally kept closed in the winter months and people spend more time indoors, indoor air is recycled more during this time of year. In order to keep the air quality in your building healthy all season long, you will need to have the properly maintained air filtration system.
Change Your Air Filter
When outdoor temperatures drop below 40 degrees, it’s your air filter that allows you to keep the air from getting “stuffy” without the need to crack open a window. However, in order to work properly, an air filter needs to be free of dirt and debris. Replace filters according to the schedule recommended by the manufacturer, or use a pressure gauge to determine when the filter has reached its final pressure drop.
Choose Filters with Mechano-Electret Media
With mechano-electret filters, businesses can reap huge benefits. These filters offer a combination of electret and mechanical efficiency and are more powerful at eliminating particles from the air that could cause respiratory problems.
Look into the ASHRAE 52.2 Test Report
The filtration efficiency of HVAC air filters in Richmond are rated by MERV: the Minimum Efficiency Reporting Value. It is measured by the ASHRAE 52.2 Test Standard, which provides the efficiency of the filter over three particle size ranges. It is crucial to inspect the ASHRAE 52.2 Test Standard, especially if occupants in your building have respiratory problems.
When it comes to contamination control in your facility’s operations, it’s important to maintain the immediate identification of contents in order to prevent cross- contamination. Not only does this streamline maintenance, but it eliminates the potential for multiple issues.
ColorGuard™ adapters from Air Sentry efficiently identify a reservoir’s contents and keep them contained. The innovative, anodized color-coding system is available in eight distinct colors, and various models are available to suit your facility’s operations.
- Drum Adapter Kits allow fluid handling through one adapter while maintaining the storage container integrity. Air Sentry breathers can be installed on any storage tank or drum.
- Hydraulic Reservoir Adapter Kits allow breathers to be installed on any hydraulic fluid tank or reservoir. The aluminum adapters have quick connects in two sizes for pumping oil in and out, allowing the system to remain closed at all times.

- Gearbox Adapter Kits (available in ½”, ¾”, and 1”) allow breathers to be installed on any gearbox, and oil can be pumped in or out without opening the gearbox to the atmosphere. They are a faster, simpler and cleaner way to handle gear oils and reduce ingression.
- Bayonet Adapters replaced a standard breather cap on a hydraulic reservoir. Simply remove the breather cap, place the adapter on the flange, and rotate.
While portable and stationed filters operate the same, they can serve different needs for your facility and your business. When you choose the right option, you will be maximizing your return on investment, saving time, and extending the life of your equipment.
If your facility has multiple machines that all use the same type of oil, it may be cheaper to buy one cart that can service them all. If your company is new to filtration systems, a mobile filter cart can allow employees to see the benefits of precision lubrication firsthand. This way, the ROI of filtration can be proven internally before committing to more units.
Mobile filter carts, such as ones from Parker and Donaldson Process Filtration, are lightweight and easy to move. This makes them ideal for equipment that isn’t always kept in the same spot.
With filtration units remain in the same place, this helps ensure consistent cleanliness. This is because there is no downtime for contaminants to accumulate when your filter runs continuously. This makes a difference over time, as high contamination levels can cause damage to sensitive machinery.
Additionally, a lower-capacity panel unit can cost less than a more powerful mobile cart system. When you combine this with the savings from continuous filtration, a panel unit is often the best choice for your budget over time.

According to Forbes magazine, Americans spend an average of 90% of their time indoors. In the majority of these cases, air quality is far worse inside than it is outside.
“Sick building syndrome” is the name given to a collection of illnesses and symptoms that afflict multiple occupants of a particular building. The symptoms include sinus infections, itchy eyes, scratchy throats, upset stomachs, headaches, difficulty concentrating, and fatigue. Complaints of these symptoms and overall discomfort can be localized in a particular room or office, or can be widespread throughout the building.
If this reminds you of your facility, there are luckily steps you can take to address the problem. Poor IAQ (indoor air quality) is very often the culprit behind SBS, and some initial strategies you can use to address it include:
- Upgrade all HVAC air filters in your facility from MERV 8 to MERV 11 in order to remove as much particle waste as possible
- Improve ventilation to provide outside air to occupants and to dilute and/or exhaust pollutants
- Identify the sources of air pollution, then remove or reduce the source
