  • Are long-held beliefs and taboos on recycled water reducing in Southern Africa?1

    A sample of 1,114 households in three countries located in the Limpopo River Basin was surveyed to investigate willingness to use (WTU) and willingness to pay (WTP) for different quality attributes of recycled water. The results indicate that 36% of the households are willing to use recycled water for potable uses and only 70% are willing to use it for non-potable use such as gardening. WTU ...

  • Researchers: Current global groundwater recharge models inaccurate

    A large-scale analysis of existing water resource models used around the world has found some key processes are missing, which means estimates of water availability could be wrong and cannot be reliably used for making water management decisions. The international team of scientists found that important climate change impact models are wrong in some areas. One finding was that groundwater ...

  • 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 ...

  • Tracing groundwater recharge sources beneath a reservoir on a mountain-front plain using hydrochemistry and stable isotopes

    Mountain-front recharge, including mountain block recharge and stream seepage, is important for basin aquifers. With the construction of reservoirs in mountainous areas and the recurrent seepage problems of dams, reservoir seepage might become another type of mountain-front recharge. This study identified the recharge sources of groundwater beneath Huangbizhuang Reservoir on the North China ...

  • Israel leads world in water recycling

    Roughly 90 percent of the wastewater generated in Israel is reused, making it the leading nation in water recycling, according to an article in The Tower Magazine. It cited a report from Israel’s water authority. Although the precise amount varies, the nation is clearly the leader in water reuse. Spain recycles 20 percent of its wastewater, making it the second largest nation for water ...

  • Empirical relationship between soil permeability and resistivity, and its application for determining the groundwater gross recharge in Marpoyan Damai, Pekanbaru, Indonesia

    In this article, a novel approach to measuring the gross groundwater recharge rate over a district area is presented. It is based on soil resistivity measurements. It is nondestructive, and allows quick, low-cost mapping of infiltration over large areas, which makes it particularly relevant for land planning. An empirical relationship between soil resistivity, ρ, and permeability, ...

  • Reference: Clever water recycling with chlorine dioxide

    Vapour water at the Crailsheim-Dinkelsbühl dairy is disinfected and then returned to the production process by means of a chlorine dioxide system. The great news is that this significantly reduces water consumption and operating costs. Fewer costs The 160 members of staff at the diary "Milchwerk Crailsheim-Dinkelsbühl eG" process around 130,000 tonnes of milk a year, ...

  • Commercial vehicle wash - case study

    Problem: A large city local authority identified significant infection risks at one of its waste depots, where its fleet of dust carts were cleaned using a commercial vehicle wash on a daily basis. This vehicle wash recycles the water, and was infected with water-borne bacteria. The aerosol droplets sprayed over the dust carts were a serious infection risk to employees and the ...

  • Quantification and characterization of greywater from schools

    Survey of schools of different education levels (primary, intermediate and secondary) in Kuwait showed an average greywater generation rate of 7.3 L/p/d and varied  in the range of  2.9 – 16 L/p/d, reflecting the school level of education (i.e. student age). The highest rates were observed for primary schools while the lowest rates were observed in secondary schools where students ...

  • Evaluating the performance of water purification in a vegetated groundwater recharge basin maintained by short-term pulsed infiltration events

    Infiltration of surface water constitutes an important pillar in artificial groundwater recharge. However, insufficient transformation of organic carbon and nutrients, as well as clogging of sediments often cause major problems. The attenuation efficiency of dissolved organic carbon (DOC), nutrients and pathogens versus the risk of bioclogging for intermittent recharge were studied in an ...
