Potable Water Treatment With Application of the GACS Method of Zeologic S.A


General Information
Potable water has to fulfill some certain characteristics. Namely:
  • to be clear,
  • to be colorless,
  • to be odorless,
  • to be cool (of a temperature around 7 – 11 degrees Celsius).
  • to contain a small quantity of inorganic salts (around 0,5 gr. per litre),

Clean water without dissolved salts is harmful for consumption. For this exact reason, sea fishes die when transferred to freshwater and freshwater fish die instantly when transferred in distilled water, because of destruction of red blood cells (hemolysis). Potable water contains dissolved oxygen, nitrogen, carbon dioxide, minimal traces of organic substances, and traces of plant microorganisms. Potable water has to be examined:
  • physically (temperature, clarity, taste, smell),
  • chemically (quality and quantitive control of substances, sclerometer),
  • microscopic (microorganism research),
  • bacteriological (culture of water microbes) and
  • topographically (water source position, path).

Thus, it is therefore directly understood how crucial is the decision of choosing the appropriate water treatment method for rendering it potable, and complying on all demanded requirements, since it has a direct impact on public health.
The GACS Solution (Geochemical Active Clay Sediment)
The Geochemical Method GACS consists an innovative solution on an international level on the subject of potable water treatment. The key characteristic of the Geochemical Method GACS is the usage of geopolymer materials, which have the ability to adapt on the characteristics and particularity of any type of waste. Under this manner, process optimization and performance maximization are achieved.
Benefits of the GACS Method, on treatment of urban wastewater against the conventional existing methods can be summarized in the following:
Financial Benefits:
  • Competitive investment cost
  • Significantly reduced operational cost
  • Reduced maintenance cost
  • Reduced sludge production
  • Reduced operational time

Environmental Benefits:
  • Heavy metals removal even on high concentrations
  • Elimination of pathogen microorganisms
  • Production of constant high quality water in accordance with the characteristics set by existing legislation
  • Production of inert sludge
  • Use of natural materials
