  • Evaporation and retention structures

    On natural, unsealed areas evaporation is the main part of the water balance among surface runoff and percolation. In Germany, an average of 60 % of precipitation evaporates on unsealed areas. If the intend is a natural hydrological balance, great importance is attached to evaporation. Besides, measures for rainwater harvesting, that have a positive impact on evaporation can contribute positively ...

  • Urban evaporation rates for water-permeable pavements

    In urban areas the natural water balance is disturbed. Infiltration and evaporation are reduced, resulting in a high surface runoff and a typical city climate, which can lead to floods and damages. Water-permeable pavements have a high infiltration rate that reduces surface runoff by increasing the groundwater recharge. The high water retention capacity of the street body of up to 51 l/m2 and its ...

  • Comparing Evaporative technologies for the Recycling of produced Water

    Both multi-stage and MVR evaporators are capable of producing distilled quality water from produced water.  Distilled water quality ranges from 100 to 500 ppm TDS depending upon the initial TDS of the produced water and the level of concentration of bottoms (waste) obtained. Typical systems are capable of attaining final concentrations ranging from 270,000 ppm to 350,000 ppm TDS.  The ...

  • Water and vapor movement with condensation and evaporation in a sandy column

    The diffusion of warm, humid air into an initially cold, dry, sandy column was analyzed to study the movement of water vapor and liquid water under nonisothermal and low water content conditions. The analysis was performed using the HYDRUS-1D code. While the water retention curve of sand was measured experimentally, the unsaturated hydraulic conductivity function was inversely estimated from the ...

  • Effects on evaporation rates from different water-permeable pavement designs

    The urban water balance can be attenuated to the natural by water-permeable pavements (WPPs). Furthermore, WPPs have a 16% higher evaporation rate than impermeable pavements, which can lead to a better urban climate. Evaporation rates from pavements are influenced by the pavement surface and by the deeper layers. By a compared evaporation measurement between different WPP designs, the grain size ...

  • Spray flash evaporator for low-temperature saline water desalination application

    A new spray-type flash evaporator is suggested for the application of saline water desalination. The flash evaporator is 1000 mm in height and 1200 mm in diameter, with a water injection arrangement inside. The evaporator design is based on experiments conducted at vacuum pressures between 10 and 18 mm of Hg, and at saline feed water temperatures between 26?C and 32?C. The saline water is ...

  • Biodegradation of artificial monolayers applied to water storages to reduce evaporative loss

    Repeat applications of an artificial monolayer to the interfacial boundary layer of large agricultural water storages during periods of high evaporative demand remains the most commercially feasible water conservation strategy. However, the interfacial boundary layer (or microlayer) is ecologically distinct from subsurface water, and repeat monolayer applications may adversely affect ...

  • Estimation of pan evaporation using soft computing tools

    Estimation of evaporation plays a key role in managing water resources projects. Traditionally, evaporation is determined using theoretical and empirical techniques as well as by pan observations. Practically, it is difficult to install evaporation pans at every location and empirical approach like Penman's equation is data intensive. This necessitates the use of an alternative approach, which ...

  • Energy cost for desalination evaporation versus reverse osmosis

    The selection of the appropriate desalination technology between evaporation and reverse osmosis is grounded on several factors, including investment cost, maintenance cost, degree of availability, heaviness of the duty, and the required purity of the desalinated water. The main factor is often the running cost of the plant, and specifically the cost of the consumed energy. This paper intends to ...

  • Extension of an existing model for soil water evaporation and redistribution under high water content conditions

    Most crop, hydrology, and water quality models require the simulation of evaporation from the soil surface. A model developed by J.T. Ritchie in 1972 provides useful algorithms for estimating soil evaporation, but it does not calculate the soil water redistribution resulting from evaporation. A physically-based model using diffusion theory, described previously by Suleiman and Ritchie in 2003, ...

  • Toxicity assessment of oil field produced water treated by evaporative processes to produce water to irrigation

    During the productive life of an oil well, a high quantity of produced water is extracted together with the oil, and it may achieve up to 99% in the end of the well's economical life. Desalination is one of mankind's earliest forms of saline water treatment, and nowadays, it is still a common process used throughout the world. A single-effect mechanical vapor compression (MVC) process was tested. ...
