A Few Points On Municipal Water Treatment In Kenya

By Betty Murray


Treatment of water is essential in making it safe for human consumption. Other than drinking, it is important to treat it for other domestic purposes such as washing, cooking and even for use by animals . Hard water may not lather easily when washing clothes. Untreated water used for bathing can result in skin infections and allergies. Municipal water treatment in Kenya should be given utmost consideration in all places across the country to safeguard the lives of citizens.

Filtration, sedimentation, aeration, use of disinfectants and chlorination are some of the methods involved in the treatment process. As to what technique will be employed in a given situation, it should be stated that it largely depends on the type of substance being treated against.

To reduce the amount of waste that goes to the environment, various used materials can be treated and reused for the same purpose or for any other use. Recycling not only keeps the environment clean but also reduces the cost of manufacturing. Failure to treat the waste water makes it expensive to maintain industrial machinery because of tendency to form scales that result in increased heat resistance. This also causes blockage of pipes. Treatment aims at regulating oxygen and alkalinity levels.

Treatment on an industrial scale is crucial. It mainly ensures that dispensing too much waste into the environment is minimized. This is because treated water can easily be recycled. Clean water also keeps industrial machinery from scaling. Scaling is bad because it increases resistance to heat. This means that more heat will be required to produce steam thereby increasing production costs.

Management of effluent utilizes electricity for effectiveness in a large scale setting. Running electricity is expensive in the long run and thus may not be affordable for the low social economic class. For this reason, the government and its citizens should be creative enough to come up with an alternative cheaper source of energy.

Sewage material should be treated before being discarded to the environment. The process here entails separation of solids from the liquid part. Common steps involved in effluent management include slow sand filtration, activated sludge and aerated ponds. Aerated lagoons, also known as ponds utilize oxygen to facilitate oxidation of microbes. Activated sludge equally works in the presence of oxygen. At the end of day, solids are carefully isolated from the liquid.

The sand in the slow sand filters system is not the real filter. It only acts as a substrate for the actual filter. The real filter is a biological film that exists naturally in the sand. The system is usually dug one to two meters below the ground. It can either be rectangular or cylindrical in shape.Such a system is simple, cheap and can easily be taught to rural communities.

In conclusion it is important to state that an effective effluent management process is essential in sustaining the well-being of communities. Various methods are now available. These can be biological, chemical or electrical. The disadvantage of electrical methods is that very high levels of electricity are consumed which may not be affordable for developing nations hence the need to also consider renewable energy.
