Effects Of Water Pollution On Decolourisation

2472 Words10 Pages

ABSTRACT
Water is the most needed resources of life. Thus, water pollution is one of the major problem that is causing more environment that other pollutions. Many industries have been using colouring dyes intensively because of their low price and easy availability and it is most widely used in cosmetic, paint, food , rubber, textiles and many other industries. Many microorganisms such as bacteria, actinomycetes, yeast and fungi are able to decolorize dyes, with colour removal by these being mainly attributed to adsorption of the the colouring agents that are dyes. In the present study, different textile effluent samples and soil adhering to it was collected from textile dye Industry were screened for dye decolorizing organism. Algae and fungal strains were able to remove the color of the dye in its initial days of treatments with 48 to 72 hours of incubation. Micrococcus gave maximum decolourization of all the dyes (80-90%) followed by Acinetobacter and Bacillus where as Pseudomonas and Staphylococcus showed lower rates of decolourization.
KEYWORDS: Biodegradation, Dyes, Effluents, Bacteria, Algae, Fungi INTRODUCTION Environmental pollution may be of many types which leads to loss of economy of the world thus water pollution and the methods to curb it are of great importance. More than a million different textile dyes with an estimated annual production of 7x105 metric tons are commercially available worldwide1 they are easily released into the environment thus

    For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.

    A subtropical wilderness with grass marshes, forests thick with trees hundreds of years old and hardwood hammocks (trees that only grow a few inches tall but packed very close together but can take up acres). Seems like a place to protect. Ever since the 1900 draining of the everglades, the ecosystem has shrunk by 50%. People did not see how important the Florida everglades where. The effect of the polluted water in the everglades is causing problems for both people and the inhabitants of the everglades.

    Lake Erie has been a huge topic for Ohioans due to how polluted the water is. Lake Erie is Ohio's biggest water source, and that being polluted is not good for Ohio and other states that use Lake Erie’s water. Though this is not the first time this has happened before, in 1960 the lake was VERY polluted due to heavy industries lined up on the shore lines. Lake Erie called the “Dead Lake” for how much pollution was in it, and how many dead fish there were.

  • Green Algae Pollution In Florida

    314 Words  | 2 Pages

    Florida has a lot to boast for with it’s beautiful beaches and vibrant wildlife that attracts many tourists from around the world. This attraction to Florida, however, is being plagued by the overwhelming amount of pollution that Florida is facing. This pollution can range from the simplest form of a trash littered beach that almost any resident of Florida can attest to or it can take the form of something much greater. This greater form of pollution is the massive outbreak of green algae that has occurred in Florida with one of the most recent back in July of this year. The algae outbreak is caused by “fertilizer sewage and manure pollution that the state has failed to properly regulate” as stated by Earthjustice spokeswoman Alisa Coe.

    This was proven partially correct, because the algae showed signs of greenness for two weeks after we added the pollutant, but began to die off in the third week of our experiment. Furthermore, the amount of algae seemed to decrease, which was very surprising. As a matter of fact, this also happened to several other containers of algae, such as Positive Control and Carbonated Beverage. The amount of algae seemed to decrease, which was strange because we never removed the algae from its container.

    The first synthetic dye, Mauveine, was accidentally discovered by William Henry Perkin in 1856 while he was looking for a cure for malaria. Different dyes are made of different dye molecules. Dyes have colour because they absorb light in the visible spectrum (400–700 nm), have at least one chromophore, have a conjugated system (a structure with alternating double and single bonds), and exhibit resonance

    DYEING Dyes are coloring materials used in dyeing textiles. Other hand it can be defined as a substance which may be natural or synthetic use to change or add color to the textile materials. They are incorporated into the fiber by chemical reaction, absorption, or dispersion. Dyes differ in their resistance to sunlight, perspiration, washing, gas, alkalizes, and other agents; their affinity for different fibers; their reaction to cleaning agents and methods; and their solubility and method of application.

    About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
