Why Don't All Water Treatment Plants Have Tertiary?

In modern times, accessing clean and safe water is paramount to the health and well-being of communities. Water treatment plants serve as integral entities in purification and provision of safe drinking water to the populace. The process of water treatment continues to undergo advancements and nomenclature re-engineering as time progresses. Some plants have the tertiary treatment process integrated into their system, while others don't. This article is dedicated to addressing the issue: "Why don't all water treatment plants have tertiary?"

Tertiary Treatment: What Is It?

Tertiary treatment refers to the final stage of the water treatment process wherein specialized processes are employed to rid the water of remaining trace levels of contaminants. Such contaminants typically include microorganisms, viruses, and other organic impurities. The tertiary treatment process allows for the production of high-quality, potable water that meets or exceeds set regulatory standards. It is a crucial process in guaranteeing safe water quality and overall credibility of the water treatment plant.

Why Don't All Water Treatment Plants Have Tertiary?

Despite the benefits attached to the inclusion of tertiary treatment, not all water treatment plants have them integrated. There are various reasons for this trend that can range from economics to technological factors.

Economics

The cost of treating water to potable standards tends to vary based on methodology and treatment stages. Tertiary treatment processes, such as membrane filtrations and reverse osmosis, can be economically demanding on treatment plants with limited financial resources. As such, the high cost of implementing the process serves as a limiting factor that significantly affects the decision-making process of treatment plant management on whether to adopt tertiary or not.

Technological Factors

The complexity that characterizes the tertiary treatment process can also deter some water treatment plants from integrating the system. It requires an intimate knowledge of the process and specific skill sets to operate effectively. Treatment plant staff would require thorough training and retraining to gain expertise in the system, which can constitute significant hurdles for some plants.

Regulatory Frameworks

Regulations and public policies governing water quality control can also play a factor in the decision to integrate tertiary systems. The enforcement of rigid regulations can be both beneficial and challenging for water treatment plants. Although tertiary treatment systems can guarantee high water quality standards, plants that meet regulatory standards without tertiary processes may save on costs without penalty of regulatory violation.

Conclusion

Water treatment plants serve as crucial entities in availing clean and safe drinking water to families and communities. Although tertiary treatment systems can guarantee potable water quality, not all treatment plants integrate it. Factors such as costs, complexity, and regulatory frameworks can all play a role in the decision-making process. It is important to acknowledge that each water treatment plant operates under unique circumstances and that these circumstances impact their adoption or non-adoption of the tertiary treatment process.
