Water treatment and hydraulics

CRM Group has developed a specific knowledge and in the engineering and testing of water treatment systems.

Hydraulic separators

Many plants, including industrial steel plats, have to process water to separate light liquids (oil, petrol) and grease from the bulk flow. Light elements are separated from water by means of gravity and/or coalescence.

Testing hydraulic separators aims at both sizing the required equipment (depending on the total flow and content of awkward elements) and characterise its performances. Grease separators are characterised according to current standards (Class I or II)

The tests are performed according to the following standards:

  • EN 858 for light liquid separators
  • EN 1825 for grease separators

Maximal water flow rate on the existing bench test: 30 l/s

 

Water treatment and recovery

Our hydraulic laboratory is also equipped to study and simulate complete water treatment processes at small scale; this includes a wide range of sensors (pressure, temperature, flow) to measure the key parameters of the processes. A few examples of our past developments:

  • We have set-up a test bench to characterize a small wastewater treatment system according to EN 12566-3
  • We have designed and performed pilot tests for a process to treat wastewater from SMEs in the agro-food industry by anaerobic digestion
  • We have studied the treatment and recovery of grey waters on several real implementation cases, mainly small buildings such as hotels and sport centres; in other projects, we have also worked on the recovery of the heat content of grey waters
 

Custom made tests

Using our hydraulic equipment and knowledge, we also perform custom tests. A few past examples:

  • Study for a depolluting road structure, using a specially-designed test bench to simulate natural rain
  • Characterization of a rain filter, of centrifugal pumps (flow/pressure), etc
