Control of Filters for Residential Water Systems

residential water systems

An example of a system with five stages of treatment.

IFTS, with its extensive knowledge in Filter Testing and Chemical Water Analysis, has the ability to test cartridge filters, reverse osmosis modules, and treating devices found on water circuits in homes and residential buildings.

Testing detects and reduces the following polluting compounds:

  • Unwanted Elements (hardness, chlorine, nitrate)
  • Metallic Mircopollutants (copper, lead, nickel)
  • Organic Micropollutants (hydrocarbons, pesticides)

Samples are taken regularly for several weeks or months. For further information or for a quotation, please contact IFTS Sales Manager Marion Dalex at marion.dalex@ifts-sls.com.

IFTS Laboratory Replaces Centrifuge

The new centrifuge allows IFTS to conduct trials over a greater range of operations.

The new centrifuge in IFTS’ Agen laboratory.

The centrifuge can be equipped with six 250 mL flasks. Suspension centrifugation tests are possible with a rotation speed up to 9500 rpm. Sample preparations are also possible depending on the temperature or rotation speed.

The replacement of this laboratory equipment enhances IFTS’ coverage to provide better availability of centrifuges and disk centrifuge separators in your industry.

IFTS Laboratory Acquires Pendant Drop Tensiometer

The tensiometer in IFTS’ laboratory in Agen, France.

IFTS has a new measuring device: a pendant drop tensiometer, which measures the surface tension of liquids.

The tensiometer characterizes the behavior of fuel/water interfaces over a period of time during water separation efficiency tests performed according to the ISO 16332 standard.

The tensiometer’s analysis software provides accurate and repeatable characterization of liquid/solid/gas interfaces.

IFTS Presents Liquid Filtration Testing Basics Short Course at AFS Fall Conference

Jerry Lynch, President of IFTS, Inc. USA, right, speaks with an attendee at the AFS Fall Conference in Cincinnati, Ohio.

The American Filtration & Separations Society’s (AFS) annual Fall Conference was held in Cincinnati, Ohio from October 14-16th. The conference was focused around the topic of ‘Innovations in Filter Media and Membranes.’

President of IFTS, Inc. USA, Jerry Lynch, presented the half-day course which discussed liquid filtration testing and test methods.

The course covered filter test techniques and standards for water, fuel, lube oil, hydraulic fluids, and other industrial liquids. Particle characteristics and efficiency methods and ratings were also reviewed.

After taking the 4-hour course, attendees left with a better understanding of the principles and methods available to pre-qualify and optimize liquid filtration selection.

Over 140 participants attended the conference from 10 countries.

The 2014 AFS Spring Conference will be based on the subject of ‘Oil & Gas and Chemical Processing’ from March 24-26th in Houston, Texas.

Centrifuge Filtration and Microwaves

As part of the DATCEMO (Dewatering Thermally Assisted Coupling Centrifuge Filtration and Microwave Drying) project, IFTS transformed its centrifuge filter pilot in order to implement thermal energy during the centrifugation cycle.

Centrifuge Filter Pilot and its environment

Centrifuge Filter Pilot and its environment

The centrifuge filter IFTS Participates in ISO 16232 Inter-Laboratory Testpilot uses a microwave generator and twenty sensors to measure the key parameters of the process (flow rates and temperature of liquid and vapor, rotation speed, liquid ring position, cake height, power consumption, electromagnetic field, temperature in the cake, moisture of extracted air). This measured data is used to establish the balances (mass, temperature, force, energy) on the liquid and solid phases.

IFTS has the capability to study and assess the interest of coupling mechanical separation and microwave drying in the same machine. Industrial areas targeted are chemistry, pharmaceutics, and the textile industry.

IFTS Participates in ISO 16232 Inter-Laboratory Test

IFTS was invited to participate in an inter-laboratory test, as part of the validation process of the ISO 16232 standard (2007; Road vehicles — Cleanliness of components of fluid circuits — Part 3: Method of extraction of contaminants by pressure rinsing). Sixteen other French laboratories, including three independent laboratories participated in these trials.

IFTS’ laboratories were able to extract the most accurate amount of particulate pollution possible.

IFTS is an independent specialist in cleanliness checks and an ISO 17025- accredited test laboratory.

Filter Cold Test Chamber

A top and side view of the chamber.

After repeated requests from aircraft manufacturing firms, airplane engineers and aerospace filter manufacturers, IFTS has invested and developed a highly accurate cryogenic filter test chamber.

The complete test system and associated equipment, is housed in a fully insulated cold chamber which allows in depth filter tests at temperatures as low as -40°C, flow rates up to 50 gpm (200 L/min), and at differential pressures up to 90 psid (~6 bar). The flexibility of the system design allows us to perform various custom test configurations. This might include the filter and all its associated components tested within the cold chamber at a constant low temperature, or another popular method is where all equipment is held outside the chamber at ambient temperatures and only the test filter is inside at the low test temperature.

As an example; a recent test program consisted of monitoring the clogging and physical behavior of kerosene filters in the presence of trace water in kerosene at -45°C and a flow rate of 50 L/min. Water was injected upstream the circulation pump to create an emulsified test fluid and ∆P was continuously recorded until the end of test value was reached. The results provided an in depth and unique view of these challenging conditions.

Validation Criteria of an APC Calibration Suspension Preparation Loop

Globally there is a need for highly accurate particle counting. This is especially true in the filtration and separation industry. An ISO expert group took on the responsibility to draft the new specification for the improved calibration fluid, SRM2806b, which will be used to calibrate optical particle counters worldwide.  IFTS accepted the development challenge and used its expertise in particle counting and cleanliness control to develop a new world class fluid process and production system to produce the new calibration fluid.

 6b Secondary Calibration Fluid

SRM2806b Secondary Calibration Fluid

The initial challenge was to produce four hundred, 400mL bottles with an ISO suspension of silica powders in a standard mineral oil and to guarantee that the particle size distribution is replicated in each and every bottle.

With this new validated equipment, IFTS can now guarantee online particle stability within 1 % >4 µm(c) and 5 % >40 µm(c) and larger.

Our new equipment will allow IFTS to supply the world market with the most repeatable secondary calibration suspensions ever prepared according to ISO 11171.

NIST is currently validating all the bottles in their labs in Maryland.
