  • Advancements in Scaling Calculations and an in depth look at Antiscalant dosing for stressed waters and high recovery systems

    Abstract Over the past few decades the Reverse Osmosis (RO) industry has observed an increase in applications in challenging waters. Water sources that were never considered suitable for RO are now commonplace, including municipal waste streams, industrial waste, and even mining waste. Furthermore, regulatory restrictions, environmental obligations, solid waste expenses, and water supply ...

  • How big is the distributed energy opportunity for water and wastewater utilities?

    Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of ...

  • Building Energy Modeling 101: HVAC Design and Operation Use Case

    A great deal of energy use in buildings goes toward heating, ventilation, and air-conditioning (HVAC). In 2015, HVAC consumed 15.5 quads. The first step in reducing HVAC energy use is reducing heating and cooling load—i.e., the amount of heat that needs to be added to or removed from a building—typically by reducing heat from equipment and lighting; minimizing unnecessary ...

  • Articulated Concrete Blocks Provide Much Needed Protection for Your Pipeline

    One of the many ways that articulated concrete blocks can protect pipelines is by adding structural stability in areas that are particularly prone to erosion. This erosion is not the only type of hazard posed to your pipeline, though, and if you don’t have the proper protection in place, your pipeline could be susceptible to deterioration at the hands of these other threats as well: ...

  • What is Chemical Oxygen Demand (COD)?

    Chemical Oxygen Demand (COD) analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Specifically, it measures the equivalent amount of oxygen required to chemically oxidize organic compounds in water. Why Measure COD? COD is used as a general indicator of water quality and is an integral part of all water quality ...

  • Advanced Integrated ZLD Systems

    The Hybrid ZLD approach pairs the best of membrane and thermal technology to make ZLD affordable, yet robust and reliable. Over the past decade, the Hybrid ZLD systems i.e. integrated zero liquid discharge (ZLD) systems have emerged as die most effective ZLD approach for dealing with the most difficult to treat wastewaters in many industries including power, refining, and chemicals. The Hybrid ...

  • Integrated Rural Water Management in India

    Integrated Rural Water Management will look to provide ecological security of water for both domestic and livelihood needs. There will be equitable access of water to all at affordable prices. The system will be maintained locally by the Village Water and Sanitation committee and there will be a legal framework in place for both water quantity and quality maintenance. Sanitation and health will ...

  • Integrated modeling on water resource management

    World is facing a water crisis and increasing in recent years. It is necessary to understand the water system from source to sink and about 10% of total annual runoff is being used. Agriculture is found largest direct user of water. Asia is consuming about 23%, highest percentage of available water resources. Various steps for efficient water resources management are discussed. Decision support ...

  • An integrated system dynamics – cellular automata model for distributed water-infrastructure planning

    Modern distributed water-aware technologies (including, for example, greywater recycling and rainwater harvesting) enable water reuse at the scale of household or neighbourhood. Nevertheless, even though these technologies are, in some cases, economically advantageous, they have a significant handicap compared to the centralized urban water management options: it is not easy to estimate a ...

  • Integrated sustainability assessment of water systems: lessons from the Ebro River Basin

    This paper describes the co-development and implementation of visioning and experimenting exercises, agent-based modelling, and gaming tools in Integrated Sustainability Assessments (ISAs) involving stakeholders. These new tools are aimed at supporting reflexive learning and at building alternative policy relevant knowledge and evaluative paradigms for managing sustainability. The specific case ...

  • On data requirements for calibration of integrated models for urban water systems

    Modeling of integrated urban water systems (IUWS) has seen a rapid development in recent years. Models and software are available that describe the process dynamics in sewers, wastewater treatment plants (WWTPs), receiving water systems as well as at the interfaces between the submodels. Successful applications of integrated modeling are, however, relatively scarce. One of the reasons for this ...

  • Combining multimedia models with integrated urban water system models for micropollutants

    Integrated urban water system (IUWS) modeling aims at assessing the quality of the surface water receiving the urban emissions through sewage treatment plants, combined sewer overflows (CSOs) and stormwater drainage systems. However, some micropollutants tend to appear in more than one environmental medium (air, water, sediment, soil, groundwater, etc.). In this work, a multimedia fate and ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • Easy To Integrate: Dezentralised Treatment Of Process Water

    Technical processing systems are some of the most complex industrial plants in existence. In the petrochemical industry, lor example, a great number of chemical products can be manufactured from crude oil and natural gas as a result of chemical-physical processes using such systems. They are designed by special companies, such as the Engineering Division of Linde AG, which having installed over ...

  • New trends in power and desalination integrated systems

    Demand for desalinated water has increased sharply in recent years, not only in desert areas but also worldwide. To be able to meet such challenging future demand whilst maintaining reasonable water costs that can be sustained by the end users, real water management should be developed. This should include the limitation of leakages in the water distribution mains, adequate design of end user ...

  • Integrated Wastewater Management

    ' Appropriate wastewater management, within an overall water resources management program, is essential to responsible use of the environment and to affordable provision of services. Such management programs are best developed at a river basin or sub-catchment level. An approach is outlined for developing a wastewater strategy and an implementation plan for a river basin.' Integrated ...
