Testing and Piloting Services

  • Get accurate parameters before going full-scale
  • Establish correct process performance indicators
  • Choose the best option – onsite or laboratory testing

Test Before Scaling Up

In many cases, it is useful to run laboratory tests or carry out onsite piloting to find the right chemistry or establish performance indicators for a process. Industrial wastewaters are often individual in composition and quality. This means that testing can be the best way to get accurate evidence on solution requirements before going bigger and scaling up to the final solution.

Not all water treatment solutions require testing before offering a solution. Aeration for example can be sized with good reliability based on initial site information: see more on Roxia Floating Aerators.

To define what is needed and how to get started, Roxia professionals are there to help choose the best approach and possible testing practices.

Laboratory-scale testing for smaller volumes

Lab testing is the quickest and cheapest way to get an idea of how a water sample responds to the selected treatment. In some cases, lab tests are enough for sizing the full-scale solution; sometimes it is reasonable to extend to onsite piloting based on the results before going for permanent installation.

Plasma oxidation tests

Plasma oxidation testing gives straightforward information on the required oxidation power to achieve desired results. Generally, the testing is conducted by running a sample in the plasma unit for a given time and taking samples at predetermined intervals. Analysing the relevant parameters from these samples provides removal curves as a function of applied plasma energy. Gathered information serves as applicability and sizing indication.

Coagulation and flocculation tests

Often in wastewater treatment, coagulation and flocculation chemicals are necessary to enable separating impurities. Chemical coagulation and flocculation enable transforming the impurities into a more separable form. These impurities can then be separated from the water with processes like flotation or settling. This testing is done with JAR tests. Our laboratory has a range of different polymers. By testing, we suggest the most suitable polymer and dosing for your application. Depending on your needs, we can then proceed with slurry filtration tests.

  • Coagulation & flocculation chemicals
  • Polymers
  • Solid/liquid separation assessments and moisture analyses
  • Reporting.

Filtration and sludge dewatering tests

After flotation or settling stages, we go from wastewater to sludge treatment. The sludge stream typically requires further dewatering to reduce the amount of waste for further handling or transportation. Roxia offers dewatering solutions that can also be tested in both laboratory and pilot scales. We usually use the following small-scale test units:

  • Smart Filter Press Test Unit 0,18 m2
  • Filter – Press Test Units, sizes 0,01 m2 and 0,02 m2
  • Geotextile filtration bag tests
  • See more on filtration testing HERE.

 

Piloting and onsite testing

Piloting and onsite testing can provide performance data on a more practical level and in continuous operations. Onsite piloting is the most accurate way to demonstrate process suitability. We offer flexible piloting with simplified connectivity to site operations with containerized pilots for plasma oxidation and complete water treatment processes. In many cases, our piloting units correspond to full-scale capacity.

To assess piloting opportunities at your site, Roxia professionals are always ready to help define the best approach and plan the testing procedures – contact us.
