SUMP-SIDE FILTRATION IS A VIABLE OPTION IF THERE IS NO ROOM OR MONEY FOR A REMOTE MODULE

Sump-side filtration is one of the two options a plant can use to clean the coolant in stand alone machines without always dumping the fluid and without retrofitting a larger filtration system as a central facility. The two options are:

• Remote recovery modules with transporters carrying the coolant to and from the machine.
• Sump-side filtration.

Remote recovery modules are filtration systems designed to be positioned in a remote area. The remote module unit receives dirty metalworking fluid from the machines via transporters or pipe lines. The coolant is cleaned with an efficient cleaning device and held in a clean liquid tank for another transport or separate pipe line to send it back to the machines. This works well when there is space and money available for transporters. The module can clean the coolant off-line to level of clarity acceptable to the operations. It is like a remove and repair maintenance program.

Sump-side filtration is much closer to the machines. Instead of the coolant going to the filter the filter goes to the coolant. A sump-side unit moves to the side of the machine and with hoses removes the coolant, cleans it and immediately returns it to the machine. There is not swapping of batches as in the remote unit.

Both systems have advantages and each fits certain plant conditions better than the other.

Harrigan Solutions understands these conditions and can offer advice on when to use sump-side filtration. We offer engineering help on how to select the best option to fit your needs. We sell or rent new and used sump-side filtration units depending upon the customers economical goals. Harrigan Solutions offers service programs where technicians can operate the cleaning schedule or service the equipment for customers who do not have the staff to cover this area.

USED FILTRATION EQUIPMENT HAS FLEXIBILITY SO SIZE IS NOT A DEAL KILLING ISSUE

If you need a filter or another coolant cleaning device quickly and your budget prevents the purchase of a new system, the used filtration equipment market is worth pursuing. The chances of getting used filtration equipment at the proper size may be remote, but fortunately you may not have to buy the exact size you need. You can consider the available devices whether they are smaller or larger than what you need. Filters and centrifuges have the flexibility be fit in different area of the system and at different flow rates. Two key points that must be first satisfied are; it is a good price for the project and it will meet the delivery schedule? If these are met then the other criteria will come into play. For example:

• If a filter is larger than needed the flow can be reduced. The filter will have a lighter load to yield cleaner fluid and use less media.

• If the filter is smaller than the needed flow it could be set up on a sidearm loop. Depending upon the percent of total flow through the sidearm loop, there is a high probability that the side arm flow will reach acceptable levels of fluid clarity and media consumption.

• A stack disc centrifuge has so much flexibility that its selection can handle large reservoirs. Its level of efficiency is so high that most of the time it is on sidearm loops anyway.

• If the goal is sump cleaning than portable sump-side units can be used. The variable is the scheduled cleaning frequency.

Harrigan Solutions understands these conditions and can offer advice on how to incorporate a used filtration equipment into your system. They offer engineering help on how to select, install and control the flow to the used filtration equipment. They sell or rent new and used filtration equipment depending upon the customers economical goals. Harrigan Solutions offers service programs where technicians can monitor the operation, perform routine maintenance, and train personnel for customers who do not have the staff to cover this area.

IF THE PRICE IS RIGHT, USED COOLANT FILTERS CAN BE AN ECONOMICAL CHOICE EVEN IF THEY ARE BIGGER THAN WHAT YOU NEED

If you need a filter quickly and your budget prevents the purchase of a new filter you can go shopping for a used coolant filter. The chances of getting a used coolant filter at the proper size are remote. So consideration must be given to filters either smaller or larger than what the system would normally use. Over sized used coolant filters can be a good buy for many reasons, the first two of which are if the price is right and if delivery meets the needed target.

The other reasons are related to the filters’ performance. Filters are selected on the basis of flow per square foot of filter area which is established for each different application. The flow rate is based on field experience of the application which balances the filter ability to achieve the desired clarity with an acceptable media usage rate. A larger filter does not have its designated flow sent through it. If the system uses a lower flow than the designed flow rate of the filter and the filter only handles the needed flow, the used coolant filter will achieve better coolant clarity with less media consumption.

The media reduction is significant. For example, field data shows that if a filter operates at a flow rate at 25 percent less than the design rate and nothing else changes, media consumption drops almost in half. If the filter operates at 50 percent the media consumption drops almost 70 percent. Also, since the media is staying in the bed longer it has an opportunity to generate a tighter film or cake from the intercepted contaminants. The tighter cake is a better media and the fluid reaches a higher clarity level.

Harrigan Solutions understands this phenomenon and can offer advice on how to incorporate a used coolant filter into your system. We offer engineering help on how to select, install and control the flow to the used coolant filter. We sell or rent new and used coolant filters depending upon the customers economical goals. Harrigan Solutions offers service programs where technicians can monitor the operation, perform routine maintenance, and train personnel for customers who do not have the staff to cover this area.

USED COOLANT CENTRIFUGES HANDLE MANY DIFFERENT COOLANT APPLICATIONS

Used coolant centrifuges can handle a wide range of cleaning needs for both waterbase and viscous oils. The most versatile is the disc stack high speed centrifuge. It has the ability to handle many typical applications:

1. Liquid/liquid-separating two fluids combined in an undesirable mixture
2. Liquid/solid- separating solids suspended in a fluid
3. Liquid/liquid/solid- separating the three components (two liquids and solids) in a mixture

Liquid/liquid separating applications:

• Tramp oil removal from waterbase fluids
• Tramp water removal from oil

Liquid/solid separating applications:

• Surface polishing operations
• Air scrubbers
• Cooling water
• Electrical discharge machining (EDM)
• Lapping
• Micro sizing
• Quenching oils

Liquid/liquid/solid separating applications:

• Parts washers
• Coolant clarification
• Waterbase quenchents

Used coolant centrifuges which have the bowl design can serve many of the liquid/solid separation applications and are not usually efficient on liquid/liquid separation.

CONTROL THE FLOW TO YOUR PRESSURE FILTERS AND YOU WILL CONTROL THE COSTS OF YOUR MEDIA

Flat bed, roll media pressure filters are selected for a given application at a specified flow rate so it can accomplish the cleaning function with an acceptable level of media usage. The flow through the filter is know as filter flow or filter flux and is measured in gallons per minute per square foot (liters per minute per square meter).

Once a system is started, the flows through the pressure filters are adjusted to meet the design flow rates. Control of the flow is important so it does not exceed the GPM per square foot rating because there is a correlation between flow rate and media consumption and performance. If the flow is higher than the designed rate the filter will use more media.

Many installations have allowed the filter flow through pressure filters to increase beyond the designated rate because:

1. More machines were put on the line without adding capacity of the filtration system.
2. Flow is increased because more flushing is perceived to be needed.
3. Valves are randomly opened without understanding actual flow design criteria.

The first item may show some justification since it may be less expensive to use more media than it is to revamp the total system for the added machines; assuming fluid clarity levels are acceptable. However, items 2 and 3 usually result in wasting money on media and sacrificing performance. The cost the extra media could be significant because the correlation between flow and media usage (when all other conditions are the same) is not linear. For example;

• Flow rate increase of 25 percent- media usage goes up 70 percent.
• Flow rate increase of 50 percent- media usage goes up 260 percent.
• Flow rate increase of 75 percent- media usage goes up 400 percent.

Harrigan Solutions understands this phenomenon and can offer advice on how to mitigate the problem. They offer engineering help on how to control the flow or how to improve your filtration system if enhancement is needed. They sell or rent new and used pressure filters depending upon the customers economical goals. They also have service programs where technicians can monitor the operation, perform routine maintenance, and train personnel for customers who do not have the staff to cover this area.

METALWORKING FLUIDS CAN INTERACT WITH ALUMINUM CHIPS AND FINES TO CREATE A PROBLEM WITH THE FLUIDS’ CHEMISTRY

When machining or grinding aluminum it has been found that the freshly cut surfaces which stay in the fluid for extended periods can react with the some metalworking fluids and create salts or soaps. The undesirable material can affect the lube package of the metalworking fluid and/or it hardness parameter. When the concentration of this undesirable material grows to a point where the coolant can no longer function and the fluid appears to “die.” Studies indicate that this reaction varies with metalworking fluids and often it does not occur until the fluids’ life has been extended by standard filtration.

One possible step which can be taken to minimize this problem is to enhance the filtration to remove more of the aluminum particles which are less than 8 micron. The high count of extremely fine material could be the main contributor to this problem. Better filtration will help.

Harrigan Solutions understands this phenomenon and can offer advice on how to mitigate the problem. We offer engineering help on how to improve your filtration system if enhancement is needed. We sell or rent new and used filters depending upon the customers economical goals. Service agreements are offered where our technicians will perform the maintenance functions for customers who do not have the staff to cover this area. Our crews can perform maintenance to any level the customer wishes. In addition, our technicians can assist in upgrading the actual filtration equipment wherever it is economically viable.
