an endeavor such as the effluent water treatment project will have a residual effect with consumers in that it will portray the company as being both proactive and environmentally responsible. Shareholder perceptions may also be considered as non-quantitative costs associated with projects. Some may also view further diversification as straying from the Pan-Europa core brands. These negative shareholder perceptions can be translated into decreased market value. The Effluent project is a must do project
and the cost of purifying the water has increased dramatically. The main sources of water pollution are point source and non point source. Point sources include pipeline discharge of pollutants such as domestic sewage discharge industrial waste effluents from factories or plants, to receiving waters. In contrast, non-point pollution results from storm runoff, which transports polluting materials diffusely over land. Water pollutants are of different types such as oxygen demanding wastes, disease
industry. It requires 30 to 40 ltrs of water for processing one kilogram of rawhide to finished leather. Traditionally, most of the tanneries have been located next to water bodies or rivers, as a source of water supply and discharge. The composition of effluent from the tanneries is complex mix of many toxic contaminants. Firstly, the wastewater from beam house process is highly alkaline and contains decomposing organic matter, hair, lime, sulphide and organic nitrogen with high levels of BOD and COD. Secondly
textile wastewater industry [37]. Treatment of spent dye effluent by means of a method using ultraviolet light (UV) and a strong oxidant is an effective alternative for the removal of color. Hydrogen peroxide (H2O2) is the most common oxidant utilized in combination with UV. Chlorine dioxide (ClO2) additionally has oxidative capabilities for color elimination. Further, UV in aggregate with ClO2 is a likely treatment for the reduction of colored effluent from textile dyeing facilities. Ozone is one of the
Sand is made of mostly various amount of material weathered from inland rocks that is blanketing the beaches, riverbeds and deserts of the world. It is composed of different material that depending on the area. Thus, it can be classified into three different forms such as; i) Fine sand (0.075 to 0.425 mm) ii) Medium sand (0.425 to 2.000 mm) iii) Coarse sand (2.000 to 4.270 mm) However, the classification of sand is further has types of sand in particular and the most common sand are pit sand
ABSTRACT The dyes & dye intermediate industry consumes large quantity of water & produce large volume of wastewater from different generated steps in dyeing process. The effluents generated are heavily coloured & contain high COD/BOD value. The effluent causes depletion of dissolved oxygen which has an adverse effect on the aquatic ecological system. There are certain physio-chemical, biological & advanced wastewater treatment technologies which are helpful in wastewater treatment of dye industry
monitored and managed because of their impacts on the natural water bodies. The Tampa Bay estuary has seen been a receiving body for effluent wastewater for an extensive period of time (Janicki et al., 2001). Tampa Bay receives effluent waste water from four watersheds; Hillsborough Bay, Old Tampa Bay, Middle Tampa Bay and Lower Tampa Bay. The effects of the effluent discharge in the water body may have negative effects on the natural ecosystem. More specifically the dissolved oxygen levels as well
The treatment of surface wastewater is aimed at bringing contaminated water back to its previous state for domestic use or otherwise. Some of the sources of wastewater include industrial effluents from manufactures, agricultural effluents, agro-industrial as well as domestic wastewater from sinks, bathtubs, toilets, and so on. Particles in the water from the various sources include bacteria, organic matters, and sand which cause the water to be turbid or discoloured in appearance and have an unpleasant
Environmental protection and preservation is a new pressure point that authorities and consumers are using to encourage manufacturers to adopt green production. In this case, as the operations manager of a large automobile company, the CEO has requested a meeting to discuss climate change and the implications for the enterprise. For the meeting to be fruitful, it is imperative that I prepare a briefing paper to address climate change and relate it to the company 's operations. Second, I need to furnish
of the effluent discharge, there is often little impact observed downstream of the effluent discharge, but greater impacts are noted when receiving stream is in a pristine condition. Biomonitoring is considered to be an effective technique to assess these impacts since it provides a holistic, integrated measure of river health which can be used to improve community participation and management of our river systems. 3. HYPOTHESIS The hypothesis for this research assignment is: The effluent released
ground water and lakes. Ground water gets adversely effected when residues from waste, leach into the ground water. Leachate is a waste that forms as water trickles through contaminated areas leaching out the chemicals. Movement of leachate from effluent treating plants, landfills and waste disposal sites may result in hazardous substances entering soil, surface and ground water. Delving further, we realize that ‘Waste management’ essentially means “the collection, transport, recovery and disposal
The water we use never goes away. Planet Earth will never have any more or any less water than what it has right now. So what about the water you use to shower, wash dishes, or flush the toilet? Most people wouldn’t give much thought about where their water comes from, or where the wastewater drains. Where wastewater goes and how it is treated will affect overall quality of life. Wastewater can affect many things such as plants, animals, wildlife habitats, and quality of life. Clean water is vital
This review shows the pros and cons of using the combination of various technologies for industrial wastewater treatment plant. Rapid industrialization, intensive agriculture and other human activities cause soil degradation, pollution and lowers the productivity and sustainability of the crops that further increase the pressure on natural resources and contribute to their degradation. Environmental bioremediation is an effective management tool for managing the polluted environment and in restoring
30oC can be influenced by factors such as geographical position, seasonality, diurnal period, circulation of air, and quantity of cloud cover, depth of water and flow rate. Also, abnormally high temperatures can arise from discharges of industrial effluent and sewage treatment plants (Chapman and Kimstach 1992). pH
Another social impact of eutrophication is an overall loss of biodiversity in areas of severe nutrient input due to the hypoxic conditions that can occur. As large amounts of algae go through their life cycles, decomposers subsequently eat the dead algae. As these algae are decomposed, the decomposers use up the oxygen in the surrounding water which leads to low oxygen conditions if carried on for long periods of time. Due to these low oxygen conditions, other organisms such as fish cannot survive
Biofilms are defined as complex aggregates of microorganisms which are interlinked and secrete extracellular slime, which forms the matrix for the films. The extracellular slime is chiefly made up of polysaccharides. Biofilms are usually irreversibly attached to a surface, in that once a biofilm is attached to a surface, it is quite difficult to remove. Mineral salt crystals, clay and silt particles etc. are also sometimes present within the biofilm matrix (depending upon the surroundings). The majority

general, air pollution effect has cost the region about $3 billion in a year. The polluted air plays a part in the global climate changes such as warmer temperatures and rising sea levels. The water in the city is also not spared by the industrial effluents. The water has been found to contain Volatile Organic Compounds (VOCs) which are chemicals from industrial discharges. The residents, therefore, are prone to health hazards associated with the toxic
There are many industrial manufacturing processes in use around the world that discharge large amounts of wastewater effluent into local waterways. These discharges are often a main source of pollution for the surrounding environment. Industries that use large amounts of water for manufacturing processes have the potential to pollute waterways through the discharge of their
