For private and public institutions owning or managing water reservoirs having problems with high levels of water nutrients
-related trophy, we offer the PROTE-fos comprehensive lake reclamation service, eliminating algae and blue-green algae blooming and improving water transparency. Unlike the radical and complicated reclamation methods usually applied, the PROTE-fos method consists in chemical binding of phosphorus, accumulated over dozens of years in lakes, directly in bottom
sediments. Repeated algae blooms can only be prevented by eliminating the process of phosphorus releasing from bottom sediments.

The PROTE-fos technology is the core of our comprehensive lake reclamation process – the chemical method of binding  phosphorous, as the element responsible for algae blooms in lakes, in bottom sediment. The key PROTE-fos innovation is the specially-constructed two-unit vessel PROTEUS (consisting of surface and underwater modules) that triggers controlled resuspension of bottom sediments, at the same time dosing chemical substances that permanently bind phosphorous. This makes the phosphorous inaccessible for algae, stopping their growth and reducing the intensity of blooms. Water thus becomes more transparent, and the ecosystem returns to a dynamic balance state. This comprehensive and individualized approach to each lake by means of the PROTE-fos method gives the opportunity to accelerate natural and desirable processes in lakes as well as the chance to improve the attractiveness of the land surrounding a given lake.

PROTE-fos technology has been implemented in two urban lakes – Winiary and Jelonek, in Gniezno, Poland. The reclamation project was performed in years 2009 – 2010 and resulted in positive ecological effects. Water transparency increased, as did the biodiversity of flora and fauna in the lakes. The lakes have become more attractive to residents as places for recreation.

Advantages of the technology:

  • Innovation – the method is new, more effective and longer-lasting than
    other methods (e.g. sediment dredging, pumping or filtering the water).
  • Comprehensiveness – the technology not only consists in binding
    phosphorus but first of all it facilitates reclamation of balance in the entire
    reservoir.
  • Field-tested effectiveness – the method has been successfully applied
    to conduct reclamation project over two lakes in Gniezno, Poland.
  • Scientifically-proven effectiveness – the technology uses the most
    up-to-date knowledge on water ecosystems.
    Guaranteed ecological effect – projects can be undertaken based on a final -effect contract.
