Hadera Paper is a leader in the area of water conservation. In the past twenty years, the company’s engineers have executed wide-ranging activity in favor of water conversation by use of water saving devices and by raising awareness to the issue which leads to savings. Furthermore, the company is active in reintroducing wastewater into the paper production process for the goal of reducing fresh water consumption. This activity has led to a 70% reduction in water consumption in the production of 1 metric ton of paper and has ranked Israel first in this criteria among paper producers worldwide.
The use of water as part of the paper production process has steered the company, for many years, to become a leader in Israel in the development of solutions for quality improvement of treated wastewater and wastewater.
The Hadera site is equipped with the most advanced treatment systems in Israel, which include 3 treatment stages:
- Pretreatment with drum filters at the wastewater exit point, allowing the filtration of solids.
- Biological treatment with anaerobic and aerobic systems for breaking down organic matter.
- Tertiary treatment for softening the water with lime with the use of the advanced technology Crystalactor, preliminary sedimentation, sand filters, and treated wastewater sterilization system.
In light of the excellent quality of treated wastewater produced in these treatment systems, the production site has received permission, from the Israeli Environmental Protection Agency to release the treated wastewater back to the Hadera Stream under the highest strictest requirements.
The water softening system, Crystalactor, enables to significantly reduce the level of treated wastewater hardness (the ability to produce scale deposits). By doing so, the treated wastewater can be reused in the packaging paper machines, hence replacing fresh water with treated wastewater.
Hadera Paper has selected to perform the softening process by using fine sand granules for generating sedimentation of scale deposits. To our knowledge, this method of wastewater treatment does not exist anywhere else in the world, and particularly not in the paper industry.
The advantage of this method is based on the fact that no harmful by-products are released to the environment. The only by-product in this process are gravel-like lime granules which are environment-friendly and can be used in the construction industry.
Process-related Waste Treatment
The paper recycling process emits miniature paper fiber particles which are unsuitable for paper production. These particles constitute the major part of paper production process waste.
This recyclable waste is reused in secondary applications and instead of sending it to landfills, it is used in agriculture. Waste treatment leads to savings in raw materials and contributes to environmental protection.
