Wastewater Treatment: Innovation and Sustainability
In a world where protecting the environment and access to drinking water are crucial concerns, Wastewater Treatment Plants (WWTP), Seawater Desalination Plants (WWTP), Drinking Water Treatment Plants (DWTP), Industrial Wastewater Treatment Plants (IWTP), and Water Reuse or Regeneration Plants (WRTP) are indispensable solutions. These infrastructures, developed by companies such as INGEOBRAS, not only guarantee the availability of water, but also ensure its quality and reduce the environmental impact of its treatment. In this article, we will explore in depth these technologies and their importance in the preservation of one of the most vital resources of our planet: water.
How is wastewater treated?
Wastewater, generated by human and industrial activities, represents a threat to the natural environment when it is not properly managed. Untreated discharges can release toxic substances, triggering major ecological disasters. In this context, wastewater treatment makes it possible to transform wastewater into clean water, safe for both the environment and the living beings that inhabit it.
Stages of the clean-up process
Wastewater treatment and purification varies according to the type of pollutant present in each specific situation. This process typically involves a combination of carefully designed physical, chemical and biological processes in order to restore the water to a safe state for reuse or reintegration into the environment. Each stage of this important process will be examined in detail below.
Pre-treatment
Pretreatment is the first line of defence in the treatment process. Its main objective is to prevent damage to the treatment facilities by removing large solids that could clog or damage equipment. This stage, common to all water treatment processes, is essential to ensure the effectiveness of the remaining stages.
Primary treatment
In this stage, floating and suspended solids, as well as fats, oils and grease present in the water, are removed by physico-chemical processes. Sedimentation and flotation are key techniques used to separate these pollutants from the water, while neutralisation adjusts the pH of the water for optimal treatment conditions.
Secondary treatment
Secondary treatment focuses on the removal of dissolved organic matter from the water by biological processes. Here, both aerobic processes, which require oxygen to degrade organic matter, and anaerobic processes, which operate in the absence of oxygen, are employed, producing by-products such as methane and carbon dioxide.
Tertiary treatment
The final stage of the purification process, tertiary treatment, focuses on the removal of specific pollutants and disinfection of the water for safe reuse. Technologies such as ultraviolet radiation, filtration or chlorination are used to ensure that the treated water meets the required quality standards.
WWTP - Waste Water Treatment Plants
WWTPs, such as those designed by INGEOBRAS, are key to the urban water cycle. These plants are responsible for purifying wastewater, ensuring that the effluent discharged into the environment meets the established quality standards. Specialising in biological treatment, INGEOBRAS has implemented a variety of its own innovative technologies, developed in its innovation and development centre (Inngen.io), to adapt to the specific needs of each project.
The design of a WWTP must consider various aspects, from the treatment capacity to the final disposal of the waste generated. In addition, it is crucial to comply with legal regulations related to discharge, water reuse and sludge management. INGEOBRAS, with its extensive international experience, excels in this aspect, ensuring compliance with local and global regulations.
