Fullers Earth Estimation:

So how much? That's always the question they ask. But are you not sure how much Fullers Earth you need? We found this chart that estimates the amount of fullers earth by weight that is required per gallon of oil to be processed.

This handy chart provides a means of estimating the amount of fullers earth you need, by weight, all you need to know is the amount of oil to be processed!

What is Fuller’s Earth?

Fullers Earth is Activated Clay, commonly used to remove surfactants and additives from fuel oils including jet fuel, kerosene, and diesel. It also removes products of oxidation and acids from hydraulic and lube oils. Bulk Fuller's Earth can be used at airports, in refineries, transformer repair shops, and other industries.

 

 

What to do when your filter media is blinding and you can’t filter

In a perfect world filter cloth would hold the particles it's meant to filter and those particles would in turn help to filter the rest of the particles until the filter was full. However, that doesn't always happen. Sometimes the particles clog the material also known as "blinding the media". This results in your filter media no longer filtering.

There are a few reasons this might happen:

1. The Media itself might not be a good fit for your application. The weave may be too tight, or too loose, the material might be the problem and a mono/multifilament might be the answer. For more information on material choice >>
2. The media might need to be pre-coated prior to running the solution. The use of a porous "sludge" gets the media ready for the actual filtration of your media. To learn more about pre-coating >>
3. Similar to pre-coating, a process called Body Feed may be used. This take a porous material and mixes it with the media being filtered. Acting similarly to the pre-coat, this added material keeps the media from blinding. Learn more about body feed >>

 Although this may give you some good ideas, it is always best to consult an expert to help solve your filtration needs.

So What's the difference?

WOULD YOU USE A CLARIFIER OVER A FILTER PRESS AND WHERE DO SLUDGE DRYERS COME IN?

Well the short answer is that you generally would not use a clarifier over a filter press.  They would be used sequentially.  The clarifier provides step one of the solids settling process while the filter press condenses the accumulated solids.

In a clarifier, the solids settle into a slurry by gravity feeding the wastewater from the top of the unit directed to the bottom through an underflow weir.  The water would flow back up through the inclined parallel plate pack and the solids settle in the bottom cone(s) as thickened slurry.

The solids from the clarifier are then either pumped into a holding tank to allow additional settling or directly from the bottom clarifier cone into a filter press.  Utilizing a sludge thickening tank is generally accepted procedure as this will allow the operator more time and options to run the filter press.

When the solids have settled into thickened slurry, they are then pumped into the filter press via a diaphragm pump.  A filter press is used anywhere there is a need to separate heavy solids from a liquid.  Once the slurry is compressed in the filter press, a filter cake is formed and the water that gets pumped out of the press can go back through to the system for further treatment to ensure complete compliance.

The clarifier and filter press combination drastically reduce sludge disposal costs by reducing the sludge volume.

If you want to reduce volume even further, you can add a sludge dryer at the end of the process.  It will take filter press cake and dry it to a consistency of kitty litter.  In some cases, sludge can be reduced by as much as 4:1.

Sterile Gas Filters

Why you need sterile gas filters

To reduce batch contamination, spoilage and product loss, effective sterile gas filtration is a necessary part of your process. Especially important in the food, beverage, and pharmaceutical industries, sterile gas filtration protects your product from harmful submicron particle contamination and bacterial transfer or growth.

MicroPure Segmented Filters feature a patented design that offers significant advantages over conventional filter cartridges.

The results are unquestionable: MicroPure Segmented Filters, designed for two-way flow, ensure consistent, uncompromised security for any application.

Mini Filter Series

If you have a small application or a small budget the Mini Filter Series might be the solution to your filtration needs. The same great quality and exceptional features at a lower cost to you.

Did you know you can use an evaporator to reduce your Hazmat?

According to an easy to understand article from Poly Products,
only pure clean water is evaporated from their  EVAPORATIVE TANK™. All impurities are left behind and accumulate until the point of solution saturation. Then the solids fall out and form sludge. The sludge is scavenged out by the filter press. 


"Generators can use evaporators to reduce the volume of their hazardous waste under the generator treatment requirements. However, if there is a release of hazardous waste or hazardous waste constituent to the air or the environment, this would be considered disposal."

So as a means to reduce the amount of Hazmat you need to dispose of, by evaporating out water or other non-hazardous materials, evaporation is a great method.
