This process is another way of acquiring the safe and potable water because it’svery much useful mostly to the people who live in the remotest regions in the world and those to the areas who have poor sanitation On preparing the materials needed for this project, we must use the following materials to make our water filtration system: coarse sand, fine sand, rocks and gravel. We need to use these kinds of materials because sand is a granular media and also it is so fine to collect the tiniest of the dirt of the water that human cannot see. We are also using rocks because rocks are very big so it can eliminate the biggest particulate matters trapped in the collected dirty water just as gravel. PROCESS INCLUDED IN TH E WATER FILTRATION SYSTEM First, we will use the flocculation process which helps remove the suspended particles of the dirty water. There are some chemicals involved in this process.
Motivation: Wetlands provide a wide variety of plants and are a habitat for many animals. The removal of plants from wetlands for crop fields and industrial development will impact negatively on the wetland ecosystem and the surrounding environment. Aim of Research: To investigate the effect of removing plants from wetlands. Review of Literature A wetland is an area of land that is saturated with water, either seasonally or permanently, and takes on the characteristics of a distinct ecosystem. [unknown.
Since algae consume dissolved oxygen in water, this can cause depletion of dissolved oxygen that very crucial to fish and other aquatic creatures to survive. Algal blooms is condition where algae grow progressively and this condition cause decreasing in dissolved oxygen in water and also can affect the health of water system included living organism like fish. Depletion of dissolved oxygen can cause extinction of fish population in that system. Some algae can disrupt human health because of their capabilities of elevated toxins and production of parasites that can disrupt human immune system. Human can be affected if they come in contact with polluted water, eat tainted fish or shellfish, or drink that polluted water.
The use of chemical control also poses a challenge especially when it is to be applied on a shared resource e.g. Lake Victoria. This then warrants a joint agreement from all countries that directly or indirectly depend on the resource. 2, 4-D and Glyphosate are examples of herbicides that can be used as they can kill the weeds fast. It should however be noted that the huge mass of dead plant material can lead
This is the most effective method to reduce the speed of flowing water of the rivulet. This consists of a kind of halt made of empty cement bags which is generally filled with sand, clay and other material and placed in between the stream. Typically, there could be
Crabs are particularly useful in aquatic environmental studies for several reasons and play important role in ecosystem processes and good indicator for polluted condition. The terrestrial crab plays a significant and useful modal in the study of population and also beneficial for human activities. It also contains concentrated forms of proteins, and oil that protect against heart disease. As the crabs are abundantly available locally and used in food by as diet by some people with great nutritive value, there is a potential to project it as poor man’s protein. The wide spread use of chlorinated pesticides to control pest species creates ecological disturbances which in turn affects the non target organisms.
Pond aerators can be fountains or waterfalls that help circulate the water bringing much needed oxygen into the pond. Filters are also required to help remove the toxins. Beneficial bacteria are also used in ponds to encourage proper growth and pH balance. Limestone and gypsum are used to help maintain pond
Recharge by runoff from irrigation water into groundwater as well as leaching of agrochemicals cause serious groundwater contamination problems. The clearing of natural vegetation and ploughing up of virgin land for new cultivation also affect the groundwater quality. Irrigation is one of the major sources of salinity in the soil through which rainwater flows to the water table. The dissolution of these salts finally
