Sydros Water Filter Testing Procedures

Sydros Water GmbH is an innovative German company dedicated to the development and manufacture of state-of-the-art water filter systems. Our team of experienced water experts and technology developers combines expertise with forward-looking technology to create solutions for clean, healthy and safe water. From household filters to industrial applications, we offer "Made in Germany" filter systems that effectively remove pollutants such as microplastics, PFAS, heavy metals and other contaminants. Our goal is to return water to its purest form and make a sustainable contribution to water quality worldwide.

1. Introduction Sydros Water GmbH has developed a unique water test stand that allows us to test and certify our filters under realistic conditions. The test stand simulates the water pressure of German households (0.5 to 3 bar) and enables long-term observations to analyze the performance of our filters in terms of physical parameters such as pressure loss, temperature, flow, and pressure differential. Our filters are designed, developed, and tested using state-of-the-art technology – a process that underscores our commitment to quality and innovation. Every tested product receives the German Sydros certificate, which stands for "tested, analyzed, and approved in Germany".

2. Preparation

Sample Preparation:

  • Water sample with defined initial parameters is created or provided (e.g., tap water).
  • Standardized test conditions such as temperature, pressure, and volume are established and recorded.

Product Preparation:

  • The water filter to be tested is installed according to the manufacturer's instructions.

Device Initialization:

  • The test stand and all sensors are calibrated.
  • Sensors for pressure, flow rate (l/min), pressure differential, and volume are connected for monitoring and adjusted to the specific test requirements.

Procedure Documentation:

  • All testing methods, equipment used, protocols, and test conditions are recorded in writing.
  • All steps and results are reproducible.

3. Analysis Before Filtration

Initial Measurement:

  • Water Test Stand:
    • Measurement of flow rate and volume.
    • Recording of inlet pressure.

Logging:

  • Results are documented in detail and retained as a reference.

4. Filtration Test

Filtration Procedure:

  • The water sample is passed through the filter.
  • Measurement of filtration duration to assess efficiency and flow capacity.

Operating Parameters:

  • Pressure drop (if any) across the filter medium is recorded.
  • Constant or fluctuating flow rate is checked and noted.

5. Analysis After Filtration

Output Measurement:

  • Water Test Stand:
    • Measurement of output pressure and flow parameters is carried out over a defined period.

Logging:

  • Results are documented to assess long-term efficiency.

6. Evaluation and Certification

Comparison of Measurement Results:

  • Before-and-after comparison of physical parameters.
  • Identification of deviations or changes in performance.

Report Generation:

  • Summary of results in a standardized test report:
    • Product description.
    • Test methods and equipment.
    • Raw data (measurements).
    • Evaluation according to established criteria.

Testing & Confirmation:

  • Successfully tested products receive the Sydros seal, which has been tested according to internal standards.
  • The seal is clearly declared as an internal test mark.
  • Wording: "All water filters undergo our internal testing procedure, which is carried out according to internal standards under standardized test conditions.

Provide Evidence:

  • All test results and protocols are archived to be presented if required.

Product Liability:

  • Test results must reflect reality to avoid liability claims (§ 823 BGB).

7. Completion and Validation

Archiving:

  • Test reports are kept for at least 5 years to meet legal requirements and customer inquiries.

Validation:

  • The testing procedure has been validated and provided by Endress & Hauser GmbH and Dradura GmbH.

Regular Audits:

  • Testing methods are regularly reviewed and updated to comply with legal requirements.
  • The test mark is clearly defined as an internal testing procedure.

Truthful Information:

  • All information must comply with legal requirements (§ 5 UWG) and must not be misleading.

Traceability:

  • Each test report is uniquely assigned to a product and a batch.
