Wastewater treatment – recycling sewage
The treatment of wastewater is one of the most important topics for the Bazan Group as part of its operations in the environmental sector. At the end of the sewage treatment process, the water is discharged into the sewage recycling facility – GES – which uses advanced filtering technology to treat and recycle the water for a variety of uses, such as:
• Water supply for steam boilers, to produce steam
• Additional water for cooling towers
• Water supply for reverse osmosis
The Bazan Group has reduced by approximately 75% the quantity of sewage discharged into the Kishon River. Approximately 2.5 million cubic meters are reclaimed every year (replacing the need for clean water – source water).
Treatment of emissions
The Bazan Group is implementing innovative projects in order to reduce emissions by the use of advanced technologies such as:
• Construction of two thermal oxidation (TO) plants to treat the sources of waste treatment odors
• Bottom loading of tankers carrying distillates
• Use of steam extraction to load road asphalt tankers
• Setting up RTO (Regenerative Thermal Oxidation) to treat ethylene emissions.
Transition to use of natural gas
The Bazan Group is making a large number of changes and adaptations regarding natural gas. One is the fact that it now uses natural gas in its plants, both as a natural combustible and as a raw material. This streamlines production costs and contributes to the reduction of direct and indirect costs. Moreover, the Bazan Group is working to adapt its product mix to changing market conditions which comply with the increase in the use of natural gas as a substitute for some of its petroleum products (this is a global trend).
Since 2013, the facilities of the Bazan Group have been linked to the national natural gas pipeline and they use natural gas as the principal source of energy for their operations. The Group receives natural gas in a quantity which supplies most of its needs and consequently it complies with the provisions of the emissions permits issued to it by the Ministry of the Environment. The Group is constantly striving to expand and improve its agreements with the companies operating the natural gas reservoirs.
• Construction of two CTO (Catalytic Thermal Oxidizers) to treat emissions from storage tankers in Gadiv and COL.
• Construction of an RCO (Regenerative Catalytic Oxidizer) for the Motzkin facility at Gadiv.
• Upgrading of the steam extraction facility at the tanker screening terminal at Bazan.
• Upgrading storage containers in each yard in order to reduce tanker emissions.
• Establishment of systems for continuous monitoring of pollutants in the plant’s yard.
• Replacement of burners in ovens to reduce nitrogen oxide emissions.
• Addition of chimney monitoring systems for ongoing control purposes.
