desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

improvement and importance of culture sites that will improve our state of living specifically in terms of economics. Site suitability rating systems are to be used in assessing the environmental parameters of the sites. The biophysical parameters such as salinity‚ temperature‚ dissolved oxygen‚ pH‚ turbidity‚ water current and depth of the site are to be measured.

the basin. Evaporation is especially high in its eastern half‚ causing the water level to decrease and salinity to increase eastward. This pressure gradient pushes relatively cool‚ low-salinity water from the Atlantic across the basin; it warms and becomes saltier as it travels east‚ then sinks in the region of the Levant and circulates westward‚ to spill over the Strait of Gibraltar. Thus‚ seawater flow is eastward in the Strait’s surface waters‚ and westward below; once in the open ocean‚ this chemically-distinct

Worksheet Using the assigned readings for Week Six‚ prepare a 50- to 75-word response to each of the following questions. The Oceans 1. What is the composition of seawater? The salinity of seawater ranges from 3.3 to 3.7%. When seawater evaporates it leaves behind sodium chloride‚ better known as table salt. The other components of seawater are acquired through various methods. One of which is weathering. Chemical weathering of rock releases soluble such as salts of sodium‚ potassium‚ and sulfur.

Experiment Hard Clam Juvinles term Toxicity: Introduction: Our testing involves exposing Hard clam juvinle to an interval of AgNo3 concentrations or a test sample for the purpose of determining the concentration or dilution levels that would cause the death of 50% of the organisms (LC50) exposed over 24 h and meeting the conditions defined by this method. If necessary and possible‚ the following may also be determined: a) the concentration level that causes the death of 20 % of organisms exposed

be used for consumption. 70% of the fresh water of our planet is still frozen in the icecaps of Antarctica and Greenland; while the remaining percentage is present as soil moisture‚ or it lies underground as groundwater. Main Problem How can the seawater be utilized for the consumption of different organisms? Sub problems How will the results of the said project be verified? Would the said experiment be as efficient as the RO process commonly done? Would the experiment be more likely to use less

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water

Levels above 175 mg CaCO3/L reduces natural food production in ponds which‚ in turn‚ leads to a decrease in optimal production. Salt water is slightly alkaline and has a strong buffering capacity so alkalinity is not usually of concern for most seawater and brackish water aquaculturists. 2. Biochemical oxygen demand ( and COD) It is a measure of the amount of oxygen required by bacteria‚ algae‚ sediments and chemicals over a set period of time. BOD is of importance in aquaculture because

This includes dissolved materials from Earth’s crust as well as materials released from organisms. The most important components of seawater that influence life forms are salinity‚ temperature‚ dissolved gases‚ nutrients‚ and pH. What are the three major layers (zones) found in the ocean?
