Difference between improper and proper sewage disposal

# data[].attributes.body
Improper sewage disposal is when the disposal system of waste is not properly managed and highly unsafe to environment by allowing the sewage to be openly disposed into open water and/or land. Proper sewage disposal , on the other hand, is a well organized and safe system to get rid of waste.

Large Scale Sewage Treatment
The treatment that is best for sewage treatment is disposal. This carries the sewage in pipes called sewers to a sewage works. At a sewage works two main methods if sewage disposal are used. These are biological filter methods and activated sludge method. Biological filtration is the action of bacteria in the tank breaking down dangerous ammonia, converting them to nitrites, and then the nitrites to the less toxic nitrates. The activated sludge process is a type of wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.
Two ways of biological filter methods are: Sedimentation and Percolating Filter which is also known as trickle filter.
Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge. Percolating filter are used to remove organic matter from wastewater. It uses a biological filter to treat te effluent run off from the sedimentation tank. This filter consists of concrete tanks some two meters high, filled with clinker coke or small stones.

Oil spills can suffocate fish, get caught in the feathers of birds and mammals and block light from photosynthetic plants in the water.

Oil can pollute streams and rivers.

Spilling a single gallon of oil can contaminate as much as one million gallons of water.

At landfill sites, efficient complex machinery is often used to compact the volume, to sort out to recycle and to select for different uses.
The purpose of a landfill is to bury the trash in such a way that it will be isolated from groundwater, will be kept dry and will not be in contact with air. Under these conditions, trash will not decompose much. A landfill is not like a compost pile, where the purpose is to bury trash in such a way that it will decompose quickly.

Industrial purification water is also known as large-scale water purification. This many relates to factories/ industries  who supplies the country with water such as GEBE for example.

Water can become polluted in many different ways as it moves through the environment. Purification is required to make water safe for human use.

The aim of water purification is to ensure the drink water is:
-safe for consumption
-is clear and not discolored.
-has an acceptable taste.
-has an acceptable smell.

They are many ways in which industrial purification of water which can be done in four different ways:
1. Screening- water which derives from rivers, lakes and reservoirs passes through grid screens to remove large floating materials and suspended solids.
2.Sedimentation- is the process of water being pumped to a settlement tank where the particles coagulate (clumps together) and settle.
3. Filtration- the process of where the clear water from the settlement tank passes through sand filters containing microorganisms. These microorganisms remove organic matter from the water by feeding it.
4. Chlorination- is the filtering of water is treated with chlorine to kill all harmful bacteria in the water. Fluoride is sometimes added to this stage to reduce tooth decay.

The importance of landfills in the Caribbean 

# data[].attributes.body
Waste from householders and tourists accumulate in the Caribbean. Since there's a great amount of waste, we must ensure that this does not pollute our surroundings. A local incinerator may be useful to dispose waste. They should be used sparingly because of the environmental air pollution by carbon dioxide.

Due to the increasing numbers of persons not having access to clean water, DIY purification of water is a "do it yourself' method of purificating water yourself.

Some methods of purifying water at home are:
1. Boiling- for a few minutes generally destroys all harmful organisms (makes the water safe)
2. Distillation- boiling the water and then condensing the steam on a cool surface to remove the salts.
3. Bleach purification- purifying water with bleach
4. Sand filtering- harmful materials found in the water are filtered out by the sand.

DIY Water Purification

Some impacts of human activities on water supplies include the removal, destruction or impairment of natural ecosystems. These effects are primarily a result of human activities such as pollution, landscape changes or climate change

Landfill sites use machinery to compact the volume, to sort out , to recycle and to select for different uses the various wastes.

Compacting refuse makes it difficult for vectors such as rats to penetrate and reduce the volume for space in landfill sites

- In the water there are common toxic metal ions such as lead, copper, nickel, zinc, etc.
- Metal ions are dissolved in groundwater and surface water when the water comes in contact rock or soil containing with the metals, in the form of metal salts.

The impacts of improper sewage disposal are that they are known to spreading disease pathogens since, as stated before, flow openly in the environment. They travel through broken pipes and allow the waste be exposed and could increase the risk of contaminating drinking water and is dangerous to use human sewage fertilizer unless it is first treated..

Fertilizers are plant nutrients that are added to the soil.
The plants absorb these essential nutrients from the soil to improve health, growth, and productivity.

When fertilizers enter surface water, the nutrients they release stimulate microorganism growth.

The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate.
