Outline

Introduction: The “City of Tomorrow”

Objectives and methodology

Identifying city water management components

Understanding the new water cycle

Deriving water quality control challenges

Science and technology roles, examples

Conclusions


World population growth

World population growth

The world population grows and requires more and more resources - arable land, water, energy, and biological resources

About 3.5 billion people across the globe already live in cities; the number is expected to grow up to 6.5 billion people by 2050

Expected to reach a peak of growth. Than declines due to

economic, health, land exhaustion and environmental reasons.

Declaration: There is enough water on the surface of the Earth for many generations to come. However, . . .

Inadequate water quality prevents using its full potential


Prof avner adin hebrew university of jerusalem adin holdings water solutions

Objectives and methodology

Objective: to indicate scientific research needs in meeting tomorrow’s city water demands.

  • The methodology is composed of two major steps:

  • various water system functions and roles are analyzed and listed in four categories: health, aesthetics, recycling and water-energy components; and

  • the various functions are incorporated into one water cycle, a holistic analysis is being made, from which scientific research challenges are derived.

FUTURE CITY


The city is the future

The city is the future

It is evident that more and more people live in cities

Thus optimizing the cities infrastructure prepares the world for coping with future population growth

Strategic plan:Focusing on urban water management and urban agriculture, using advanced technologies and a strong knowledge center


Prof avner adin hebrew university of jerusalem adin holdings water solutions

  • AH Concepts for Future City

  • Future City - A healthy community:

    • Water filtration and disinfection complying with current and future standards

    • Water quality monitoring, including innovative real time devices for Water Security and Safety

    • Treatment and quality control of domestic and non-domestic wastewater

    • Fire hydrant systems

  • Future City - A beautiful and fun community:

    • Effective water management for Gardening and parks

    • Surface water quality control

    • Fountains and recreational facilities


Prof avner adin hebrew university of jerusalem adin holdings water solutions

  • AH Concepts for Future City (cont.)

  • Future City - A water recycling community:

    • Planning and design of grey water and wastewater collection and reuse systems

    • All grey water and wastewater shall be reused within the Future City area

    • Sludge free wastewater treatment where possible

  • Future City - A water and energy conserving community:

    • Supply management and leakage control, with continuous data collection (and automatic billing)

    • Public education !

    • Minimizing energy usage in water and wastewater facilities


Urban agriculture

Urban agriculture

Urban agriculture contributes to food security and food safety in two ways:

It increases the amount of food available to people living in cities

It allows fresh vegetables and fruits and meat products to be made available to urban consumers

Slow sand filtration mechanisms

Slow sand filtrationMechanisms

  • Biological: enhanced bio-activity on grains surfaces. “Schmutzdecke”.

  • Physical: surface straining, interstitial straining, settling, diffusion.

  • Physicochemical: Adsorption, DLVO-van der Waals interactions.

  • Surface catalyzed degradation

  • decentralized

  • Electroflocculation-constructed wetland hybrid

  • Aerobic-anaerobic compact system

Nanoparticles removal

  • Itis inevitable that nanotechnology-based consumer products enter the aquatic environment

  • Switzerland (2014): Engineered nanoparticles are present in the leachates from landfills and are released to surface water

  • Viewed as emerging pollutants: toxic, may cause cancer, neurodegenerative diseases and other types of diseases

  • Their eco-environmental risks demonstrate strong need of developing effective water treatment processes

Nanoparticles and biofilm

  • The fate and transport of NPs are affected by biofilms.

  • Biofilms consist of bacteria and surrounding EPS (extracellular polymeric substances)

  • NPs can be transported and strongly attach to EPS surfaces

  • Initial studies (2009) have shown significant accumulations of NPs occurring in biofilms.

  • Indication (2014) that NP’s attachment to EPS is governed by electrostatic interactions

  • Mg presence may enhance biofilm formation

  • Fiber optic technology which recycles UV photons

  • Detecting and counting bacteria in minutes instead of days

  • Sludge-less bio-reactors

  • Aerobic membrane bio reactor that consumes no energy for aeration

  • Hydrophilic membrane with higher flow at lower pressure

  • Electricity produced by electro genic bio-reactor.

Conclusions

  • More than 70% of the world population will live in cities

  • Future City’s water can be best managed with the help of science under four categories: health, aesthetics, recycling and water-energy

  • A holistic interpretation of the water cycle can lead to the necessary scientific research challenges

  • Upgrade of regulations and standards is needed, must be based on scientific knowledge

  • Cooperation in water research among Mexican and Israeli scientists can lead to improved water management in the years to come
