Water application

Probiotic treatment for cooling and process water.

A high initial dose is intended to establish probiotic dominance in the water circuit. Nutrient competition and the use of existing EPS deposits as organic food aim for less biofilm. System condition, water chemistry and the existing treatment determine the dosing plan.

Industrial cooling towers with galvanized housings, a maintenance walkway and cooling-water pipes.

Systems to consider for assessment.

  • Water circuits serving air-conditioning systems
  • Water-based recooling systems
  • Wet scrubbers
  • Evaporative cooling systems
  • Heat exchangers and condensers
  • Washers and process water circuits

How a project runs.

01

Survey

System data, water analysis and existing treatment are recorded.

02

Dosing plan

The dosing plan, product suitability, dose, inoculation point and safety requirements are specified.

03

Start-up

Application follows the agreed plan. Any change to the existing treatment is technically reviewed and supported by monitoring.

04

Monitoring

Agreed microbiological tests and operating data record progress; statutory testing remains necessary.

05

Normal operation

System condition and operating effort are regularly assessed against VDI 2047 and the 42nd Federal Immission Control Ordinance.
