BOD. Similarly there is no generalized correlation between BOD and COD. It is possible to develop such correlations for specific waste contaminants in a specific wastewater stream but such correlations cannot be generalized for use with any other waste contaminants or wastewater streams. This is because the composition of any wastewater stream is different. As an example an effluent consisting of a solution of simple sugars that might discharge from a confectionery factory is likely to have organic

Wastewater can come from a variety of sources like homes‚ businesses‚ industries‚ runoff from roads‚ lawns and fields and is treated by municipal wastewater treatment facilities (Product‚ cornell). The solid material that remains after the treatment of wastewater is known as sludge (charac‚ cornell). Sludge can be employed in many different ways‚ it can be used as a soil additive or growing medium‚ sent to a composting facility‚ incinerated or landfilled (Char‚ cornell). Biosolids are derived

Since 1995‚ majority of Lason Awardees have installed wastewater treatment facilities because of the pressure created by the exposé. Some of these industries have been active in their own environmental programsand/or have partnered with SPM and government agencies invarious river rehabilitation projects. Among

Water Conservation Methods / Conserving is No Longer an Option Water conservation should not be considered an option any longer. Current circumstances require our full attention if we hope to thrive as a civilization. If these statements sound dramatic‚ it is because much of the world is currently suffering due to a lack of clean water. Statistics around the reveal that our fresh water supply is practically nonexistent. That is why it is so important to seek out‚ find and start using all the

desalination could be the ideal solution to water scarcity. However‚ the expensive cost and the detrimental influence on the environment might limit the scale and sustainability of this method. Due to the cheap cost and the minor environmental damage‚ wastewater reuse is regarded as another potential solution. However‚ it seems to have a low social acceptance. Therefore‚ this report will compare the feasibility of desalination and water reuse in terms of cost‚ social acceptance and environmental impacts

Water and Wastewater plant have to follow so that we can raise our awareness of our own backyard‚ our own streets‚ our own oceans‚ and our own world. First‚ we created our own wastewater by mixing dried up coffee grounds‚ ground-up cereal and pet food‚ cut up plastic bags‚ baking soda‚ torn up toilet paper‚ vegetable oil‚ and ammonia into water. The end result looked like actual wastewater. We proceeded to do the primary‚ secondary‚ and advanced treatment steps to treat the wastewater.

Water Pollution Water pollution is the contamination of bodies of water such as ponds‚ lakes‚ oceans‚ rivers and even groundwater. Water pollution is mainly caused by many human activities‚ which can be harmful to animals and plants which live in these bodies of water are located. Nature also takes its toll on water pollution such as volcanoes‚ severe storms‚ and earthquakes also cause major changes in the quality of water. Water is typically considered to be polluted when it’s impaired
