Project Acronym: HMIW

Project Summary


Wastewater resulting from local tannery industries in West Bank is contaminated with heavy metals, toxic chemicals, organics, and inorganics. Toxic heavy metals such as Cr, Zn, lead (Pb) and major elements such as manganese (Mn) and iron (Fe) affects human health, plant and animal life, as well as the quality of the limited groundwater when it is released to the environment. The project focused on the management and treatment of wastewater polluted with heavy metals generated from local chemical industries (leather tanning) and generalize them to galvanization and aluminum fabrication. The cleaner production (CP) principles (i.e. change in raw materials and process technology) in the leather industry were applied to minimize waste and maximize profit. Furthermore, a process for the treatment of industrial wastewater (lab-scale treatment unit) was designed and investigated. The proposed treatment unit consists of a packed bed adsorption process followed by a proper recycling/disposal of the exhausted adsorbent. The research investigated a second option for the treatment, which included clarifiers, chemical coagulation, and different sludge management options.

Overall Objectives


The main goal of this project was to recommend through pilot studies appropriate CP tools and best practices to efficiently manage industrial wastewater contaminated with heavy metals (i.e. from the leather industry) in the West Bank. Replacement of banned chemicals and implementing corporate social responsibility (CSR) initiatives in the industrial sectors were part of the recommended best practices. Furthermore, the feasibility of adopting environmentally sound and cost-effective stand-alone or hybrid technologies for pollution prevention and control in the leather industry was studied by keeping in mind the prevailing local conditions.

Specific Objectives


The specific objectives of the project included:

  • Characterizing and quantifying industrial wastewater contaminants loads from leather tanning.
  • Applying and promoting CP principles in the leather industry to minimize waste and maximize profit. Besides, assessing the market acceptance of product quality associated with selected cleaner production options (i.e. change in raw materials and process technology). 
  • Preparing an environmental plan for managing wastewater from the leather industry to ensure that industries monitor their resources and pollution intensity. 
  • Developing, optimizing, and generalizing an innovative and cost-effective technology for the treatment of heavy metal contaminated wastewater.
