Environmental Solutions for the Military

The costs associated with pollution and the disposal of hazardous wastes are astronomical.  Combined with increasingly more stringent regulations, it is critical that these environmentally related issues be addressed in ways that will not only protect and conserve our natural resources but also reduce the impact of compliance on the bottom line.

Electronic Coolants

Today's sophisticated electronic systems (flight control, target acquisition and fire control radar) rely on high-performance Electronic Coolants to ensure proper operation. To maximize the heat transfer characteristics of these systems, the coolants come in direct contact with the high-energy electronic components. In addition to the dissipation of heat, the coolants insulate adjacent components preventing electrical arcing and component burnout. The purity of these coolants is critical to maintaining this high dielectric strength. System contaminants such as particulate, water, solvents and air reduce the insulating characteristic of the coolant resulting in fluid breakdown and/or electronic component failure. You can extend the life and/or recycle these high-performance electronic coolants with the Portable Fluid Purifier.


Today's advanced fuels enable aircraft engines to burn cleaner with virtually no coking. But even state-of-the-art fuels such as JP-8 + 100 will eventually become contaminated with water. In fact, water can be a bigger problem than particulate contamination because it causes corrosion, can plug fuel lines, and may even cause engines to stall. Unfortunately, it doesn't take much water to cause a problem. And exacerbating the situation are detergents and additives that make water even more difficult to remove because they lower the interfacial tension between the water and the fuel.

To prevent maintenance and performance problems caused by "free water", it is essential to separate it from the fuel. Pall is addressing this critically important issue with high quality Coalescers.

Hydraulic and Lube Oils

Particulate contamination and water can have serious adverse effects on the physical and chemical properties of hydraulic and lubricant fluids. The loss of these properties, central to useful service life of the fluid, can result in inefficient system performance and accelerated mechanical and chemical wear processes. Here is a brief look at the detrimental effects:

Fluid contamination can take several forms and can have the following effects:

  • Erosion of nozzles and valves
  • Valve spool sticking
  • Seal wear
  • Pump wear
  • Cylinder scoring
  • Fluid degradation
  • Freezing
  • Polymerization (causing viscosity change and solids generation)
  • Oxidation and acid formation
  • Additive precipitation
  • Foaming
  • Pump damage due to cavitation
  • Sluggish system response, reduced bulk modules
  • Increased fluid temperature, fluid oxidation
Solvents (degreasers)
  • System component corrosion
  • Valve stiction
  • Erosive wear

To reduce these adverse effects and also to meet the military goal of reconditioning and reusing waste oil from land, air and sea-based vehicles that contain only a small volume of water, Pall has developed Oil Purification Systems which utilize unique spinning disk and vacuum dehydration technologies to create a fine aerosol for rapid removal of particulate matter and undesirable water, gases, and chlorinated solvents (such as degreasers) from hydraulic fluids, without damaging or altering the fluid due to excessive vacuuming or heating. The result is processed oil that's restored to a condition equal to or better than new, and which can be reused instead of discarded. And while the end result is very friendly to our environment, it also offers very attractive cost savings as demonstrated by several military examples including one in which the U.S. Army concludes that it will save approximately $2 million a year by recycling hydraulic fluids using Pall Oil Purification Systems. In yet another case, the USAF conducted an evaluation of Pall purification technologies on new and used hydraulic fluids. This Aircraft Hydraulic Fluid Purification study appears to indicate that the USAF can save $30 million a year through the reuse of hydraulic fluids.

The bottom line is that Pall oil purification technologies are providing a serious assault on oily waste problems.


Machine Tool Coolants

To maximize performance of an operating system, all fluids involved should be free of particulate contamination -- particularly coolants, which often means frequent fluid changes. But you can reduce how often you replace machine tool coolants and significantly extend their life through a superior Pall technology called Disposable Graded Pore Filtration. Pall's Profile filters which utilize graded pore technology provide effective prefiltration and filtration in a single element and last three to ten times longer than a normal filter of similar rating.

Even advanced filtration systems can't extend the life of machine tool coolants indefinitely. When the time comes for disposal, Pall is ready with a solution that will concentrate the coolant to such an extent, it will reduce your disposal costs by as much as 95%. To learn more about this cost-containment "efficiency-expert", check out our Oily Wastewater Separation Systems.

Oily Wastewater

It's a fact: Huge sums of money are being spent to dispose of oily wastes when up to 95% of the waste volume is just plain water! Additionally, regulations governing the disposal of this potentially hazardous waste are becoming even more strict. The solution? Pall's Clarisep Oily Wastewater Separators. Through state-of-the-art Ultrafiltration, Clarisep separates emulsions and particulates from the water in oily wastes. The result is a reduction of up to 95% in the volume of waste that must be disposed off-site. Because the separated water is rendered benign, it can be disposed of locally, and that will significantly reduce your disposal costs.


Controlling plating solution contamination can prolong the useful service life of the plating fluid, thus preventing pollution and minimizing waste stream volumes in addition to decreasing the number of plated parts rejected. Though many filtration technologies are available, the one chosen should have a short payback period, provide the required fluid cleanliness, not be a significant waste stream contributor itself, require low maintenance and not require the use of an abrasive filter aid, such as diatomaceous earth, to achieve the desired plating bath cleanliness. Depending on the plating application, a backwashable or graded pore disposable filtration system can be employed to reduce the level of contamination of a fluid. Pall has developed unique products that meet all of these criteria: Backwashable Filtration Systems and Disposable Graded Pore Filtration.

Pall is aggressively meeting military strategies to exceed current and anticipated regulations while significantly reducing costs, with cutting edge solutions designed specifically for Pollution Prevention, Compliance and Conservation.

Adherence to environmental policies is a cornerstone of Pall's corporate mission. And it is through our commitment to this mission that we can assure our customers in the military that we are vigilant in our campaign to meet your cost-sensitive, environmental concerns.
