For years now we have seen water resources and treating it a strategic value. We invest greatly in building the most advanced treatment arrays together and using advanced technologies to treat water in the paper machine arrays. These actions, together with increasing awareness among workers and managers, have led to us saving about 70% in water consumption to produce a ton of paper! Also, using innovative technologies to treat sewage, we can return about a quarter of the mill’s sewage water to the paper manufacturing process as an alternative to freshwater.
Using the water as part of the paper manufacturing process helped us become a leader for many years in developing solutions relating to the treatment of sewage and wastewater. The most advanced treatment systems in Israel are installed and operated in our mill, which includes 3 treatment stages:
Pre-treatment of sewage – drum filters allowing filtering solids.
Biological treatment – aerobic and anaerobic facilities to disassemble organic material.
Tertiary treatment- lime softening using the Crystalactor advanced method, preliminary sedimentation, sand filters, and a sewage disinfection system.
Due to the great quality of the treated wastewater created in these treatment facilities, the mill was permitted by the Ministry of Environmental Protection to flow the water to the Hadera river under the strictest instructions and requirements, and of course, allows us to return some of the water to the manufacturing facilities as an alternative to freshwater.
