Reverse Osmosis

Membrana osmosis

Zecron has a range of products whose main objective is to increase the performance of osmosis plants. We have a complete range of additives that act accordingly depending on the qualities of the water and different configurations of the facilities.



  • Anti-encrustations/ descaling
  • Biocides
  • Flocculants
  • Cleaners




1 Membrane autopsies of reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) plants

  • Identifying deposits / encrustations.
  • Characterization of the membrane – salt rejection and flow.
  • Oxidation and integrity tests.
  • Cleaning trials / tests.
  • Identifying the optimal cleaner, dosage, contact time and pH to eliminate deposits.


  • Microbiological analysis, counting, identification and testing of the effectiveness of the biocide on the membranes’ surfaces.
  • Study analysis of the feasibility of treatments using RO, NF, UF, MF and pilot runs/trials using flow cells.
  • Particle counting in the raw water and in several stages of pre-treatment (evaluation in different filtration systems).
  • Characterization of colloidal matter and analysis of micro filters and/or SDI membranes.
  • Feed water analysis and antifouling projection study based on potential encrustation.
  • Performance tests on a laboratory scale.
