Customization Procedure


From Our Lab to Your Site

Pilot tests measure the performance of FMX technology for our potential clients’ process objectives. We develop and customize test procedure based on information provided by the clients via Process Engineering Survey (PES) and Test Sample Description.

BKT can provide a variety of in-house and on-site pilot testing options to verify FMX feasibility and performance. This flexibility allows us to accommodate each client's specific needs in regards to testing.

To optimize the dynamic membrane filtration process, in-house testing attempts to isolate and assess several variables, including optimal membrane selection, temperature, operating pressure, concentration factor and/or % recovery rate, fouling Incidence, and CIP, etc.

Once the in-house pilot test has been conducted to identify the main process variables and verify the technical feasibility and economic justification of the FMX system for the specific application, the next step is to confirm the application of FMX membrane system at greater length and depth during on-site pilot test studies.  This pilot test will employ an FMX pilot unit, pilot size system, equipped with the previously determined optimal membrane.


Step 1

Process Engineering Survey (PES)

Process Engineering Survey is the very first step in sharing your project information with us. You will need to provide us with basic project information like your water quality and your goal by filling out our survey form.

Step 2

In-house Test (IhT)

At BKT, we understand that each sample has unique characteristics and each individual client’s goals will vary. For this reason, we prefer a hands-on approach in processing your sample to determine the optimal choice of membrane for your application. A typical in-house pilot test begins with a membrane selection test, during which 3-5 membranes are tested using the FMX-B system. This enables the comparison of various membranes for parameters. Testing a variety of membranes enables us to provide the optimum membrane for each application, providing each client with a customized solution. Just send us a minimum of 5 gallons of your sample to be processed with FMX technology for analysis. 

  • Definition of project goals

  • Analysis of client’s sample

  • Selection of optimum membrane


Step 3

On-site Test (OST)

To facilitate maximum accuracy of our design, we then emulate a full-scale processing of your sample on our larger pilot units. BKT offers a variety of options for on-site testing with full-scale FMX-E5 or FMX-S20 units. These units are trailer mounted with all internal plumbing connections, allowing for quick and easy on-site installation. However, in the events of logistical difficulties or shortage of samples, our labs can accommodate an In-House Test (IHT) with FMX- P. On-site piloting systems provide full-scale design data and can confirm both membrane performance/longevity over multiple batches and membrane cleaning procedures. Testing time can vary from two weeks to a few months. Typical on-site tests are conducted to mimic a full scale installation, providing the best results for full scale design and installation. Both IHT and OST allow us to help you determine the best real-time operation strategy, but OST provides more accurate design factors. 

  • Verification of flow rates which can be achieved using FMX technology

  • Confirm long term operation and reliability

  • Formulate optimum cleaning procedures and other operating variables

Step 4


By installing a full-scale industrial unit, you can consolidate several processes into one single step using the FMX Membrane filtration System. FMX technology can help you achieve higher concentration goals, retrieve formerly wasted materials for additional revenue, conserve resources by using less, among other benefits.

  • Consultation on ideal treatment process per BKT’s wide range of experience

  • Ideal model selection considering PRE and POST treatment with overall project objectives

  • Quantitative analysis of economic benefits and financing options
