  • Loading capacity of silica flash cartridges

    FlashPure Cartridges Optimizing flash chromatography requires finding the ideal cartridge and conditions for a given sample. As the goal is to prepare the largest possible amount of pure sample in the shortest possible time and with a minimum use of solvent, it is crucial to know how high loadings affect the separation for different cartridges. Unlike analytical chromatography, preparative ...

  • How to identify issues in water quality

    Water quality can mean different things to different people and therefore depends on what standard of quality one is looking for, for example, water may be fine for fish to live in but lack the quality required for human consumption. To measure the quality of water accurately, tests are carried out to identify several key indicators. These characteristics are then compared ...

  • Where Is the Most Water Reuse Taking Place?

    Water reuse is becoming increasingly important as water scarcity becomes prevalent throughout the world. Whether it’s referred to as water reuse, water recycling, water reclamation, or another name, the resulting purified wastewater can be used in many applications, both potable and nonpotable. In some places, water reuse has been slow to catch on, particularly because of the so-called ...

  • Assessment of domestic consumption in intermittent water supply networks: case study of Puerto Ayora (Galápagos Islands)

    Intermittent water distribution systems are a stark reality in developing countries. Puerto Ayora, the centre of tourism of the Galápagos Archipelago, is not an exception, with its population and tourists suffering from scarce water resources. However, the extreme per capita consumptions, well above those in 24/7 supply situations in many other countries, contradict the (sense of) scarcity. In ...

  • Optimization analysis of separation conditions of washed water containing a lead complex and characterization of the precipitation products

    Presently, the large amount of industrial leaded wastewater creates a great challenge to both environmental governance and wastewater recycling. Lead complexes in washed water must be removed mostly before the washed water can be recycled. This paper reports the mechanism and factors of removing Pb complexes in simulated washed water by the sulfide precipitation method. The reaction time, ...

  • Bioelectrochemical nitrogen removal as a polishing mechanism for domestic wastewater treated effluents

    Addition of an external carbon source is usually necessary to guarantee a sufficiently high C/N ratio and enable denitrification in wastewater treatment plants (WWTPs). Alternatively, denitrification processes using autotrophic microorganisms have been proposed i.e., with the use of H2 as electron donor or with the use of cathodic denitrification in bioelectrochemical systems (BES), in which ...

  • How to make domestic water reuse optimized through better strategies?

    Effective treatment of domestic waters and their reuse has become essential in modern times. Though such processes have technologically advanced in a significant fashion, it needs expertise or understanding of technology for proper execution. In addition, special strategies also have to be applied for process optimization. Strategies for greater conservation: It has become ...

  • Abatement of organic pollutants using fly ash based adsorbents

    The presence of organic pollutants in the environment is of major concern because of their toxicity, bio-accumulating tendency, threat to human life and the environment. It is a well-known fact that, these pollutants can damage nerves, liver, and bones and could also block functional groups of essential enzymes. Conventional methods for removing dissolved pollutants include chemical ...

  • The Rising Cost of Water

    There's a common economic paradox about the price tag on drinking water and value. Our current economic climate places prices on things predicated on scarcity and value. Water pricing is now more widespread, with the dual goal of expanding supply and encouraging more responsible use. So long as water remained abundant, the cheapness of drinking water is not likely to change. However, the price of ...

  • Oily wastewater treatment by adsorption–membrane filtration hybrid process using powdered activated carbon, natural zeolite powder and low cost ceramic membranes

    In this research, four types of low cost and high performance ceramic microfiltration (MF) membranes have been employed in an in-line adsorption–MF process for oily wastewater treatment. Mullite, mullite-alumina, mullite-alumina-zeolite and mullite-zeolite membranes were fabricated as ceramic MF membranes by low cost kaolin clay, natural zeolite and α-alumina powder. Powdered activated carbon ...

  • Tipping Back an “Interesting” Pint

    How about a nice tall glass of ice-cold beer… made from recycled sewage water? Did you hesitate? Well, now let’s think about it: most breweries use some combination of hops, malted barley, yeast, and…. well… clean water! But beer from recycled wastewater? That’s exactly what took place March 19-10 at the 2017 WateReuse California Annual Conference in San Diego. ...

  • Focus On Microfiltration Part 1: Filter Longevity

    For consumers using disk, syringe, and capsule filters it is a common FAQ: How long will my filter last? Or, to put it another way: How much fluid can I expect to pass through my filter before it clogs? This seems to be a simple and reasonable question for a filter consumer: Would any of us purchase a product without an understanding ...

  • Power Station Slag Recycling - Case Study

    The problem: Coal fired power stations operating tap slag boilers release most of the ashes resulting from the combustion as slag at the boiler bottom. There is a number of such power stations in Europe operative. These boilers are also known as wet bottom boilers. There are two types of wet-bottom boilers: the slag-tap boiler and the cyclone boiler. The slag-tap boiler burns ...

  • Experimental study on performance of sand filter layer to remove non-point source pollutants in rainwater

    Clogging characteristics of conventional sand filter layers with different grain-size distributions were experimentally studied to estimate their filtration capacity to capture non-point source pollutants in an artificial rainwater reservoir. A series of laboratory-scale chamber tests was conducted for artificial urban runoff synthesized with non-point source pollutants collected from a real ...
