Humidity is a natural phenomenon and is an amount of water vapour present in the atmosphere or in a gas. Water vapour itself is the gaseous state of water and is invisible to the human eye but we have all experienced how uncomfortable high humidity can make you feel. Humidity comes from water evaporating from lakes and oceans and since warmer water evaporates more quickly you find ...
Much attention has been paid to establish accurately open water evaporation since the lake itself is the largest consumer of water. The aim of this study is to assess the discrepancy in the measured (pan evaporation) and estimated (Penman) evaporation rate, seasonally, based on the results from a 37-year energy budget analysis of Lake Burrumbeet, Australia. The detailed analysis of ...
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 ...

A UK-based waste oil collector was using emulsifiers and heat to drop water out of waste lube oils and fuels. The processed oil with 0.5-1.0% water was being filtered in a centrifuge. The company installed Sequoia’s efficient water evaporation equipment which produces oil with less than 0.1% water. As a result, the centrifuge works more efficiently. Ultimately, the company makes a recycled ...
The aim of this paper is to develop a thermodynamic model for a water-to-water heat pump using propane as refrigerant. This model is based on the thermodynamic principals and heat transfer fundamental laws. The performances of the heat pump have been looked at as function of the water temperatures at the entry of the evaporator and the condenser. The results show that the cooling and heating COP ...
A model is presented to study the steady and transient state responses of the system during startup and sudden load changes/disturbances of the Multi-effect Mechanical Vapour Compression (ME-MVC) desalination system. Some of the main dependent parameters like the compressor work, and the mass flow rate of distilled water against the independent parameters like the evaporation side pressure and ...
Customer: Locomotive Service Company located in Texas - repair and maintenance of railroad locomotives and cars. The Problem: Customer installed a water evaporator system to reduce waste water volume and disposal costs. Evaporator system included a small oil/water settling tank, but no oil skimming system. Customer needed an automatic oil skimming system to continually remove the ...
The Client In the heart of Germany, the local branch of a pharmaceutical multinational company produces an anaesthetic containing 2,6-Diisopropilphenol (Active Ingredient A), and an antiviral (Active Ingredient B) made up of sodium chloride, citric acid and sodium acid phosphate. Traces of these products are present in the wastewater coming from the cleaning process of the production equipment. ...
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 ...
A desalination system using a spray tower and Vapour Compression Refrigeration (VCR) system is proposed for obtaining fresh water from brackish water. In the spray tower, simultaneous heat and mass transfer take place between the brackish water and air, which results in the evaporation of the brackish water and humidification of the air. Fresh water is obtained from the humidified air by ...
ELTS 1500 Capacity of 1500 l/h This plant treats oil emulsion from the metal working industry. The feeding water has a content of oil of 5-10%. Through a 2 step evaporator the liquid is being reduced, resulting in a content of oil of 90-95%, which is high enough for being used as fuel. The 2 steps consist of one natural circulation evaporator and one flash evaporator. The heat for ...
Cork WWP (Ireland) was designed in 2000. The specifications did require a complete sludge treatment solution including dewatering, drying and granulate storage. The system was to take maximum advantage of the biogas produced by digesters as well as any surplus heat used for the heating of the digesters. The drying equipment had to be flexible in order to cover the varying production rates and, at ...

The sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapor into the air. Ice and snow can sublimate directly into water vapor. Evapotranspiration is water transpired from plants and evaporated from the soil. Rising air currents take the vapor up into the atmosphere where cooler temperatures cause it to condense into clouds. Air currents move water vapor ...
Rainfall and air temperature variations resulting from climate change are important driving forces to change hydrologic processes in watershed ecosystems. This study investigated the impacts of past and future rainfall and air temperature variations upon water discharge, water outflow (from the watershed outlet), and evaporative loss in the Lower Yazoo River Watershed (LYRW), Mississippi, USA ...
