Petroleum Wastewater Treatment With Application of the GACS Method of Zeologic S.A.
One of the major environmental issues nowadays is the presence of petroleum in the soil, industrial wastewater and the underground water. Petroleum generated waste and its byproducts represent a significant proportion of the organic waste generated world-wide. According to estimations, at this time in Greece more than 200.000 tons of petroleum related waste and byproducts are produced, while their treatment is not always the optimal environmental solution. The environmentally sound technique of management and disposal of refinery waste has been a challenge for the petroleum industry for many years, with the applied until to this day techniques to give questionable results. A major problem also lies in the disposal of sludge after treatment, which must be stabilized and inactivated before the resulting product to be safely disposed in the environment as an inert material.
The GACS Solution (Geochemical Active Clay Sediment)
The Geochemical Method GACS consists an innovative solution on an international level on the subject of treatment and disposal of petroleum wastewater. 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 petroleum wastewater against the conventional existing methods can be summarized in the following:
- Competitive investment cost
- Significantly reduced operational cost
- Reduced maintenance cost
- Reduced sludge production
- Reduced operational time
- Heavy metals removal even on high concentrations
- Effluent complying with legislation
- Production of inert sludge
- Use of natural materials
