GACs Technology

GACS (Geochemical Active Clay Sediment) is a process created, developed, and patented by ZEOLOGIC which:

Is friendly to the environment,

Can be applied to a wide range of environmental issues

Is based upon the usage of geopolymer materials with high absorption ability

Relies on the principles of nanomechanics, achieving treatment of the pollutant load at nanoscale level. Pollutant load is captured on the crystal structure of the geopolymer materials

Produces inert , stable and non-hazardous sludge

ZEOLOGIC has developed a series of innovative products such as, nanocoagulant mediums, nanoflocculants, organoflocculant compounds, and metallic oxidation nanoparticles, which together with the geopolymer materials significantly enhance the performance of the treatment process.

The Gacs method main advantage is the specialized approach in each type of waste, achieving the maximum pollution load absorption in every waste treatment line. The success of GACS Method relies on the foundations of nanomechanics, and the unique utilization of geopolymer materials per application after the simulation of each offered solution in our fully equipped Laboratory by the R & D department of the company.

ZEOLOGIC produces the required chemical consumables in its own facilities and supplies with them the waste treatment units it executes, ensuring that way the quality and availability necessary for their long-term operation.
