Geothermal&Biogas

Water and Soil Pollution 

Geothermal hot waters are excellent solvents. Depending on the mineral composition of the rocks they pass through and the rocks they come into contact with, they contain high concentrations of salts and heavy metals. 

The elements and elemental compounds found in geothermal resources are: Ammonia (NH4), arsenic (As), Nitrogen (N2), Copper (Cu), Bicarbonate (HCO3), 

Boron (B), Mercury (Hg), Zinc (Zn), Iron (Fe), Fluoride (F), Hydrogen (H), Hydrogen Sulfide (H2s), Calcium (Ca), Carbonate (CO3), Carbon Dioxide (CO2), Chloride (Cl), Lead (Pb), Lithium (Li), Magnesium (Mg), 

Manganese (Mn), Methane (CH4), Nickel (Ni), 

Potassium (K), Radon (Rn), Silicon (SiO2), Sodium (Na),

Sulfate (SO4).

Solution

The Arbok geothermal purification technology transforms geothermal energy into a fully sustainable and efficient system for heating, agriculture, and industry — without the traditional problems of scaling, brine discharge, or chemical use.

Using a low-temperature vacuum evaporation process, Arbok separates pure water vapor from salts and minerals without cooling or boiling the geothermal flow. The result is 100% clean hot water, ready for direct use in district heating, greenhouses, and industrial applications.

The system operates with minimal energy demand (≈0.72 kWh/m³) and zero liquid waste, turning salts such as silica, boron, and calcium into reusable resources. It requires no membranes, filters, or chemicals, ensuring decades of reliable operation with negligible maintenance.

Applicable anywhere geothermal sources exist, Arbok enables clean heat and water generation even from mineral-rich or high-salinity wells — making geothermal energy finally practical, efficient, and environmentally neutral on a global scale.

Treatment Needs for Biogas Wastewater

Wastewater (digestate) from biogas plants is characterized by high organic load, nitrogen and phosphorus content, suspended solids, and foaming. It also carries risks such as calcification in pipelines, high ionic content, pH imbalance, and microbiological instability. Efficient treatment of the liquid waste generated after biogas production is critical to the overall performance, long-term success, and environmental compatibility of the plant. Currently, treatment achieved through chemical and mechanical processes only leads to a higher waste load, labor, operational, and material costs. Osmotic systems are not preferred due to their short lifespan and high maintenance costs.
