Wastewater Treatment: Problems and Solutions
Our nation’s rivers and lakes are invaluable public resources, essential to every aspect of our lives and livelihood. It is so fundamental that the United Nations passed a resolution recognizing it as a basic human right, a prerequisite for the recognition of all other rights. As the global population increases, so too does the demand for this indispensable building block of life. Freshwater supplies across the country, as around the world, are being stressed to a breaking point as industrial, agricultural, and municipal users all compete in the face of increasing scarcity. Thankfully, engineers and scientists are rising to the challenge with wastewater treatment equipment that is increasingly sophisticated, efficient, and effective.
A Brief History of Wastewater Treatment
Managing sewage effectively is an unsung hallmark of advanced civilization. The oldest flush toilets known to archaeologists are those at the palaces of early Minoan kings on the island of Crete around 3000 BC. The Indus Valley Culture’s cities of Harappa and Mohenjo-Daro had vast networks of brick canals and even flush tanks fed by aqueducts. But the waste from these ancient cities was only conveyed to the nearest large body of water. Wastewater treatment equipment wasn’t put in place until the 1890’s in the United States, after concern for the pollution in our nation’s waterways. The earliest techniques involved chemical treatment. In the 1970s, the Clean Water Act sought to expand some of the best practices already in place for treating human waste and industrial polluters.
Untreated sewage, stormwater runoff, and industrial wastewater pose as serious health risks. Chemicals that enter the river can harm in-stream species and also seep into the connected groundwater. When the chemical-laden water evaporates and becomes part of the hydrologic cycle, it falls back to earth, possibly as acid rain, and can damage crops as well as human health. In response to the necessity and action-forcing legislation like the Clean Water Act, wastewater treatment equipment is now required for any facility to discharge into the waters of the United States. In addition, the law requires dischargers to implement the “best available technology,” ensuring that the protection afforded by the equipment is always improving.
