Water Treatment Technology | Problems of the Environment Pollution

Today, the problem of the environment pollution is considered to be one of the most serious global problems. At the same time, this problem is often closely related to the problem of the water pollution. In such a situation, the arguments concerning the treatment of the wastewater that is supposed to be recharged.

Basically, there are two major ways of treatment the wastewater that will be recharged. On the one hand, it is suggested to use secondary treatment. This treatment is a continuation of the primary treatment and it further “reduces organic matter through the addition of oxygen to the wastewater which provides an aerobic environment for microorganisms to biologically break down this remaining organic matter” (Schiff). On the other hand, it is also suggested to use the tertiary treatment and recharge the wastewater that implies a more profound treatment of water.

In such a situation, many argues concerning the type of treatment that should be used for the wastewater. At first glance, it would be logical to use the tertiary treatment for the wastewater that will be recharged to replenish the groundwater. Such a decision seems to be quite logical because the tertiary treatment implies that the wastewater will undergo a complicated and highly effective process of treatment. As a result, the final product, i.e. the wastewater that will be recharged, is supposed to be relatively clean and safe water where all dangerous elements, including the organic matter which remains after the secondary treatment. Consequently, it is possible to presuppose that this wastewater will be the most environmentally friendly and most safe for the groundwater which can be later used for regular consumption. It is worthy of mention that the tertiary treatment of the wastewater makes this water closer to its natural consistency than the secondary treatment that is viewed by many as another advantage of the tertiary treatment.

In actuality, the tertiary treatment is not effective as it may seem to be when it is used to treat the wastewater that will be recharged to replenish the groundwater. The secondary treatment of the wastewater will be more effective and useful if this water is used for the recharge. The secondary treatment implies that there will remain some organic matter which is broken down by microorganisms that are present in the soil on the way of the wastewater to the groundwater and after that back to consumers. The presence of this organic matter stimulates the progress of microorganisms which evolves along with the matter they have to ‘cope with’. In other words, they grew more complicated and, therefore, more effective in the breaking down the matter remaining after the secondary treatment that means that natural treatment of the water will be more effective. In contrast, the tertiary treatment minimizes the presence of the organic matter and the wastewater does not really stimulates the development of microorganisms which contribute to the effective treatment of the water. As a result, the tertiary treatment would be simply a primitive recharge of the wastewater to the groundwater, while the secondary treatment, being less complicated, can stimulate the processes, such as the development or improvement of microorganisms that contribute to the natural treatment of the water.

Thus, water treatment is important to prevent the risk of the water contamination with dangerous bacteria. The proper treatment of water can minimize the risk of spread of dangerous bacteria through water.
