quality tubular UF membranes
CASE STUDY:
Oil/Water emulsion separation
THE CHALLENGE
The manufacturing industry produces multiple types of mixed oil and water streams. These streams are created as a result of: Parts Washing, Tool Cooling, Metal Forming or Mop Water. The issue with each of these streams is that there can be high levels of suspended solids and emulsified oils in unknown concentrations. The usual requirement is to remove the solids and oil from the stream to meet discharge regulations. Often the filtered component is reused in house. On occasion, the concentrated component can also be reused in house. The issue is that most forms of conventional or membrane filtration will foul/plug after a short time processing these streams. The challenge is to identify a reliable, economical and environmentally safe method for processing these streams.
THE SOLUTION
Many companies have contacted Filtration Systems, Inc. (FSI) to provide a solution that would work better and more reliably than other forms of filtration. FSI has developed a proprietary PVDF 1” tubular UF membrane with a tightly controlled pore distribution and a robust construction specifically for these applications. The 1” Tubular UF membrane has an open geometry that is resistant to plugging, can concentrate solids and oils to high levels, and can be mechanically cleaned with minimal downtime and without expensive/hazardous chemicals. FSI customers have been successfully using this proprietary membrane for over two decades.

CASE STUDY:
MEXICHEM SPECIALTY RESINS, INC
THE CHALLENGE
Mexichem Specialty Resins, Inc. produces various chemical products at their New Jersey facility. One of these products is a PVC latex adhesive used in the automotive industry. In order to maximize production efficiency, this PVC latex stream needs to be dewatered as much as possible, prior to being sent to an evaporator.
Mexichem discovered that 1” diameter tubular ultrafiltration (UF) membranes were the best technology for this dewatering process. The problem was that the PVC Latex would settle on the surface of the UF membranes and solidify. This resulted in the UF membranes only lasting 4-6 weeks. It was very costly, difficult and time consuming to replace the UF membranes on such a frequent basis.
THE SOLUTION
Mexichem contacted Filtration Systems, Inc. (FSI) to see if they could offer another type of tubular UF membrane that would work better/longer. FSI studied the problem and developed a proprietary Polyether Sulfone 1” tubular UF membrane specifically for the application. Mexichem has been using this proprietary membrane for over two decades, with increased efficiency and averaging over 6 months between replacements.

CASE STUDY:
The Nisshin OILLIO Group, Ltd.
THE CHALLENGE
The Nisshin OilliO Group (NOG) Nagoya Plant produces various types of edible oil products at their Nagoya, Japan facility. To maximize product quality, it is necessary to clarify the edible oils as much as possible prior to final processing. Edible oils are extremely viscous and permanently foul most types of filtration.
NOG Nagoya Plant discovered that 1” diameter tubular ultrafiltration (UF) membranes were the best technology for this clarifying process. The problem was that typical PVDF membranes had too large of a pore distribution (70kD to 140kD). This resulted in undesirable particulates often passing into the final production process. It was very costly and time consuming to continually test the process stream on a frequent basis. If particulate was found, it often resulted in either having to discard, or reprocess the batch.
THE SOLUTION
NOG Nagoya Plant contacted Filtration Systems, Inc. (FSI) to see if they could offer another type of tubular UF membrane that would work better and more reliably. FSI studied the problem and developed a proprietary Polyether Sulfone 1” tubular UF membrane with a tightly controlled pore distribution specifically for the NOG Nagoya Plant application. The result was that the edible oil was able to be clarified to a very high-quality level on a consistent basis. NOG Nagoya Plant has been successfully using this proprietary membrane for nearly two decades.
