Pickup Tube for 55 Gallon Drum

When purchasing this system, there is the option to supply your own holding tank. For small volume applications, a 55 gallon drum can be connected with the supplied pickup tube (included with purchase of a Splitter Series unit) that eliminates the need for plumbing to be added to the holding tank. Since the area at the bottom of a 55 gallon drum is fairly small, the need for a conical bottom is eliminated.

55 Gallon Drum Recommendations:

  • Polyethylene or stainless steel open-top drums are recommended
  • Steel drums are not recommended
  • Purchasing a new drum instead of reusing one you may have on hand, due to potential for contamination of incompatible material, is highly recommend

Configuration for Reuse


Cleaning Process

Full Automation

Waste is automatically transferred from Buffer Tank to Process Tank via diaphragm pump. Splitter will process the waste automatically and stop when waste is reduced to 10% of original volume (~6 gallons). Splitter will fully drain the concentrated waste via gravity (or optional pump) to the Concentrate Waste Storage Tank. This cycle will repeat until Buffer Tank is detected to be empty, or the Concentrate Waste Store drum is detected to be full.


Manual Operation, Full Drain

Waste is accumulated over the course of the week in the Process Tank. A Process cycle is manually started. Process will stop when waste is reduced to 10% of original volume (~6 gallons). The user can fully drain the concentrated waste via gravity (or optional pump) to the Concentrate Waste Storage Tank.

On average, how often do the membranes and the processing tank need to be cleaned?

Process Tank should be emptied at the end of each batch. Membranes need to be cleaned once per week, or when the permeate rate falls 10 to 20 percent below the rate after the last cleaning cycle.

How often do the prefilters need to be changed?

Completely dependent on the total volume (and size) of suspended solids present in the waste stream. Likely once per month, but it could range from few times a week to few times per year. Once a month is most likely.

How often should the membranes be replaced and what are the signs that they need replacing?

Unacceptable low permeate rate, that will not increase after cleaning cycles. Low permeate quality (visibly discolored). On average, with proper maintenance and care, membranes should last 6-12 months.

Are there issues with filtering post-emulsifiable penetrant?

Our membranes can handle post-emulsifiable penetrants so long as there is no excess amount of emulsifier in the waste water.

What is the difference between the “Ultra” and “Nano” membranes?

Nanos are tighter and are generally used for LPI applications only. The "Ultra" membranes are geared towards emulsified cutting oils, coolants, vacuum condensate, and mop water and general; waste applications. If there is a specific product in question, please contact us to discuss

Is the Pre-Filtration Assembly required for processing? If not, what is the drawback to not using this option?

Either process should have prefiltration, it will at least prefilter solids and some of the smaller contaminants. The downside is shorter membrane life.

Does the Pre-Filtration assembly include pre-filters? What are the requirements for the pre-filters?

No, they are sold separately in boxes of 4 and are relatively inexpensive to the membranes

Can you use a 500 gal tank with a 150 gal system?

Yes, as this is a batch process and you can actually hold as much of the waste in a process or holding tank as you want. However, the idea is to match up as closely as possible the amount of waste per day and then the pumping/dumping of the concentrate.

What is the estimated processing time for 55 gallons with the 2x? 4X?

About 6-7 hours with the Splitter 2X and 3-4 hours with the 4X. These are estimated figures.

What is the average electricity cost of the machine?

Continuously running for 24 hours will consume about 30-35 kWh. Multiply this by your customer's electric rate to get the cost of operating.

For reference, running this machine in the Splitter office would cost about $3-$4 (USD) per day

How do you use the cleaning solution?

Detex-NS membrane cleaning solution is not added directly to the process tank. A cleaning cycle is recommended to be done once per week, by adding about a half cup of Detex-NS to a 5 gallon container filled with clean water. Once the cleaning cycle is done, this 5 gallons of waste can be added to the process tank to be treated with the next batch.

A 1 gallon container of Detex-NS should be good for about 8 months.

Can one system be used, and membranes changed as needed depending on the material being filtered?

While the customer could definitely swap out the membranes each time, it is not something we would recommend. Changing out the membranes is a straight forward task, when done once or twice a year.

Frequent changeovers will wear out the seals and connection points. In the removal process, there is a slight chance of damaging the old membranes, which is normally a nonissue since they are to be discarded anyways but in this specific case, it would be highly undesirable.

The customer would also need to completely purge the system of any residual amounts of the previous waste, especially if transitioning from coolant waste to the penetrant waste. Membranes would also need to be stored submerged under clean water long term storage would require the addition of antibacterial and antifungal compounds to discourage organic growth.

In this scenario we would not be able to confidently claim a 6-12 month nominal lifetime for the membranes.

Should the membranes be removed from the system for cleaning? If so, how often and how should they be cleaned?

No, membranes are cleaned by "processing" a cleaning solution and should not be removed from the system. They should be cleaned once per week, or more frequently.

Are there any physical indicators that can tell you if the membrane needs to be replaced?

Yes, when the permeate rate no longer recovers to an acceptable rate after cleaning, the membranes should be replaced.
