Brochure: Water And Wastewater Industry Solutions

Wastewater is another term for sewage; water that has been used in homes, industries, institutions, and businesses that is not for reuse and is generally collected in a sewage collection or drainage system. In general, raw wastewater is 99.9% water and 0.1% impurities.

However, the impurities in wastewater can cause damage to our environment, create odors and pose significant risks to human health, if the wastewater is not treated properly. Organic matter comprises approximately 75% of the impurities in wastewater; it is predominantly human and food waste.

Nitrogen, phosphorus and trace levels of other nutrients are present in wastewater. Nutrients encourage plant growth that can generate excessive plant and algae growth in water and can be detrimental to the natural ecosystem. Therefore, it is essential that excessive nutrients be removed from the water source prior to disposal.
