Water supply and sanitation has been a primary logistical challenge since the dawn of civilization. Wastewater treatment plants have been around since the late 1800’s. Basic sewer systems have been in use almost since the beginning of human civilization, but it was the rise of industrialization and increased human density in the 19th century that prompted the creation of modern wastewater treatment plants and sewer systems.

In addition to the odor, outbreaks of deadly cholera were killing thousands in large European cities by 1850. Recognizing that untreated wastewater was the source of the problem, many cities built underground sewer systems to pipe the sewage away from human populations. Often, the waste was sent directly to farmlands for use as fertilizer.

Within a few decades, it also became possible to treat sewage by removing pollutants through chemical processes. Sir Edward Frankland is widely credited with having been the first to discover that filtration of sewage through gravel had a purifying effect, separating and neutralizing the solids. By the 1890’s, rudimentary wastewater treatment plants were popping up across Europe, resulting in cleaner and safer cities.

These early concepts for wastewater processing and treatment represent the foundation on which Lystek’s scientifically advanced solutions for Wastewater Resource Recovery were built.
