ERMA FIRST BWTS FIT is an advanced modular system that was developed to exceed all the special installation requirements either for New Building vessels or especially any retrofit project. Covering an extensive capacity range from 50 to 3000m3/h and holding USCG Type Approval, ERMA FIRST FIT is an ideal solution for all types of ships. The major components of the system are a high-end backwash filter and an electrolytic cell with outstanding performance under the most demanding conditions. The self-cleaning automatic screen filter has a nominal filtration rate of 40 microns. Its special designed screen provides with enormous zooplankton, phytoplankton and sediment removal, minimum pressure and uninterrupted, long-lasting operation at an extremely small footprint element. For the de-ballasting of the vessel there is no need to use the system; It is completely by-passed, and the water can be discharged directly overboard, after neutralization where applicable, with considerable gains in energy saving for the operators/managers of the vessel. Using an active substance that is produced by the method of electrolysis, any danger for re-growth of microorganisms is eliminated

USCG Type Approval was received on October 2017. According to the operational limitations indicated on this document, we are in a very advantageous position comparing with other makers.

Operational Limitations:

  • Salinity: Not Applicable
  • Temperature: Not Applicable
  • Hold Time: Not Applicable
  • Electrolyte Feed Temperature: > -2ºC
  • Electrolyte Feed Salinity: 0.9 Practical Salinity Units (PSU)
  • Filter Inlet Pressure: 1.6 Bar
  • Total Residual Oxidant (TRO): 6 mg/L

 

Benefits:

  • One way treatment – only while ballasting
  • Simple and Flexible
  • Suitable for all Pump Capacities
  • Suitable for all Available Spaces
  • Low Pressure Drop (0,5 bar)
  • Suitable for Fresh Water (0,9 PSU Salinity) & Low Temp. Waters (-2oC)
  • Low Power Consumption in Various Waters (1,8 kW/100 m3 at 30 PSU)
