  • Wastewater treatment facilities in Morocco and Palestine serve solely residential communities, and

    lack design considerations for the treatment of industrial wastewater discharges.

    Problematic

  • Local municipalities connect the industrial discharges to public sewerage networks with ultimate

    treatment in central wastewater treatment plants (WWTPs).

  • • These current practices lead to negative impacts on WWTPs efficacy with associated environmental, economic and socio-political impacts.

    • Considering water-energy-food nexus, climate change, water scarcity and limited access to available water resources in the MENA region, use of reclaimed water for agricultural irrigation forms a core element within an integrated water resources management.

    Problematic

  • • How achieve sustainable WWTPs with safe reclaimed water suitable for agricultural application is the main goal of this research project.

    • A cutting-edge irrigation system using a hydroretents polymer (HRP) , an eco-gum manufactured at bench scale, will be used for the removal of selective heavy metals and organic pollutants of industrial origin.

    • We argue that HRP can help local municipalities find environmentally sound solutions to reduce organic and inorganic residues from reclaimed water.

    Project description

  • The main objective of the proposed project is to :

    -Assess the chemical/microbiological contamination and productivity

    in the agricultural production chain under irrigation with different

    kinds of reclaimed wastewater.

    -Prepare hydroretents polymer (HRP) materials suitable for water

    storage and micro pollutants adsorption during irrigation.

    -Support a techno-economic optimization of wastewater treatment

    lines and their management in order to produce treated wastewater

    compatible with agriculture irrigation practices.

  • What is HRP?

    • A hydroretents polymer (HRP) is a sandwich of hessian, polymers and paper. When placed at the root zone of plants, it ensures an efficient use of water and nutrients.

    • Biodegradable HRP reduce irrigation requirements and improve the water availability in plant substrates / soils which leads to improved yields.

    10

  • What is HRP?

    • Only 7 grams of polymers can absorb 1 litre of water turning it into gel. The plant roots grow into the gel and the HRP slowly releases water providing a water buffer for 2 to 3 weeks.

    • HRP save water, labour and increase yields

  • Polymers

    The HRPs that widely used in agriculture are mainly;

    1- polyacrylate polymers.

    2- polyacrylamide polymers.

    Polyacrylates polymers are usually made with sodium and are more

    environmentally friendly

    Polyacrylamides polymers absorb only about 300 to 400 times its own

    weight in water, use a variety of potassium molecules for crosslinking.

    In agriculture Superabsorbent polymers are used in soil, as reservoir of

    nutrients, and as water absorbent media. Properties of this material are

    dependent on many factors, such as their chemical and compositional

    characteristics, soil texture, plant species and also environmental factors. 3

  • Typical cellulose-based SAP prepared via direct cross-linking of sodium carboxymethyl cellulose

    (CMC; R= H, COO-Na+) or hydroxyethyl cellulose (HEC; R= H, CH2CH2OH)

  • HRP for potted Production (Vegetable and Nursery Sector)

  • Using HRP for wind erosion control

    HRP used for tree plantation

    under the wind erosion control

  • • Locally produced eco-gum can improve the quality of reclaimed water and

    increase agricultural productivity while reducing pollution loads to receiving

    environment and public health;

    • Policy makers can integrate research results into national reuse guidelines

    through adoption of smart post-treatment technologies aiming at reducing

    the potential impacts and fate of inorganic and organic residues of industrial

    origins; eco-gum can adsorbed selective heavy metals otherwise reducing

    agricultural productivity and causing soil degradation

    SOLUTIONS/CONTRIBUTION TO WATER SCARCITY DEBATE

  • • Tailor-made training for farmers, school farms, NGOs,

    agricultural engineers, and policy makers on smart

    irrigation systems, sources and fate of potential

    pollutants of various origins can increase awareness

    raising, acceptance and improve technical skills of local

    communities in the MENA region

    • Research findings are applicable and relevant outside our

    case study to other countries in MENA region conditional

    that eco-gum is feasible to produce considering socio-

    economic context and cost-effectiveness at local market

    SOLUTIONS/CONTRIBUTION TO WATER SCARCITY DEBATE

  • • The intellectual merit of the proposed research envisage the following outcomes: Technical and decision support to policy makers and local communities towards techno- economic optimization of wastewater treatment facilities.

    • This shall narrow the knowledge gab and improve profession skills to sustain operational management of sanitation services. Considering socio-economic conditions, acceptance and optimized water and land management are core issues behind efficient water use for agricultural production.

    Development outcomes

  • • Scale-up of best synthesis recipes from bench-scale to pilot and large-scale production based on well defined parameters gathered through extensive molecular and macroscopic level characterization of the prepared hydrogels.

    Development outcomes

  • • Establishment of Research and Technical Development (R&D) group to create new knowledge regarding scientific and technological topics for the purpose of uncovering and enabling development of new products, proces
