TECHNOLOGY

ERMA FIRST incorporates the most reliable and efficient filtration followed by a state of the art disinfection stage. Filtration takes place in either 40 microns automatic backwashing filters (ERMA FIRST FIT) or in-house engineered 20 microns hydro cyclones (ERMA FIRST). The disinfection stage takes place in our own-design, highly customised electrodes, providing the appropriate amount of disinfectant agent by using minimum power and ensuring compliance. A special coating is applied on the electrodes, which are designed to minimise the production of harmful byproducts and have an extended life time of minimum 5000-6000 hrs of operation.

ERMA FIRST BWTS FIT

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/hr and having completed successfully the required tests on the way to USCG 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 neutralisation 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.
