  • Activated Carbons from lignocellulosic waste materials for water treatment: a review

    Activated Carbon (AC) adsorbents are commonly used to remove pollutants from water because of their excellent sorption ability. However, commercially available ACs are expensive. In developing countries where economy plays a very big role, it is better to find low-cost locally available precursors, which are renewable resources for the preparation of ACs. This review focuses on ACs prepared from ...

  • AFM water treatment for biodiversity

    The discharge of List 1 bio-accumulated chemicals into the marine environment is one of the most serious forms of pollution that we inflict on our environment. The marine enviroment is responsible for the production of most of our oxygen and reduction of carbon dioxide. Tropical rainforrests and terestial plants are also extremely important in dictating our local climate, however they ...

  • Types of Water Treatment Systems

    There are different types of water treatment systems, and knowing the difference between them can help you make an informed decision on just what type of treatment you’ll need for your water. There is no best water treatment system that will meet everyone’s needs—each system has its benefits and deficiencies. Here are a few ...

  • Efficient Waste Water Treatment

    Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...

  • Development of efficient characterization parameters for activated carbon used in drinking water treatment

    In many drinking water treatment facilities with an activated carbon (AC) purification step, polar and hydrophilic molecules are substances of concern. Many of the current test methods for AC do not really reflect AC's adsorption capacity for these substances. To develop a fast and economically reasonable parameter that characterizes AC's ability to remove these compounds, three ...

  • The Future in Water Treatment - An SA Water Perspective

    Adelaide’s water quality has been the subject of adverse media comment in regard to taste and odour for years. At times, algal taste and odours are evident due to the majority of water being sourced from the River Murray plus reservoirs in the Adelaide Hills – a primary agricultural area. Further, customers complain about chlorinous taste and odour in the distribution systems. Despite all ...

  • Ecological and economic aspects of carbon sorbents application in the TPP water flows treatment process

    Substantial economic and ecological effects for thermal power projects (TPPs), can be achieved by improvement of the carbon sorbents (CS) application process providing fine pre-treatment of feed water, return condensates and purification of sewage. CS with inside surface of 106 m²/kg are able to extract contaminants from liquid mediums to any desired degree of water purification both ...

  • Investigation of removal of N–nitrosamines and their precursors in water treatments using activated carbon nanoparticles

    N–nitrosamines have been detected in various water types. A strategy for removal of this group of compounds should be taken to reduce the health risks for humans. In this study, a fast and sensitive LC–MS/MS method was developed for quantitative analysis of nine N–nitrosamines and four precursors in a single sample. The Method Detection Limits (MDLs) in natural water ranged from ...

  • Carbon nanotube composite membranes for small ‘designer’ water treatment systems

    Small water systems that serve fewer than a few thousand persons are often less safe and less sustainable than large drinking water systems due to lack of suitable technologies. This ongoing research aims to develop a novel water treatment technology for small communities. By layering structured, functional carbon nanotubes (CNT) onto low pressure membranes (LPMs), composite membranes were ...

  • Energy requirements for waste water treatment

    The actual mathematical models describing global climate closely link the detected increase in global temperature to anthropogenic activity. The only energy source we can rely on in a long perspective is solar irradiation which is in the order of 10,000 kW/inhabitant. The actual primary power consumption (mainly based on fossil resources) in the developed countries is in the range of 5 to 10 ...

  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

  • Nimr Water Treatment Plant Oman

    Introduction The Nimr water treatment plant (NWTP) project is located in the south of Muscat in Oman. The temperatures in the region can be as high as 60°C in the summer months, making it a harsh environment to work in. This water treatment project was co-executed by Bauer Environment and Petroleum Development Oman (PDO). The plant came online in late 2010 and has been treating ...
