Chemical dosing for disinfection is a critical step in the drinking water treatment process, but the available solutions are often expensive. Drinking Water Treatment Drinking Water Treatability Database. Two steps typically are employed: coagulation and flocculation. Many of the species dissolved in water, however, are harmful for humans to drink, or otherwise render the water unsuitable for human use (e.g., Ca2+ is responsible for "hard water", which can leave insoluble scum on appliances and industrial boilers). Coagulation is a process to neutralize charges and then to The common steps of river water treatment are provided in Figure 3, and the processes are illustrated in the following diagram. Storage Water is placed in a closed tank or reservoir for disinfection to take place. The water then flows through pipes to homes and businesses in the community. A community should be consulted when choosing a water-treatment system and should be made aware of the costs associated with the technology. Solids maybe suspended, dissolved or colloidal. The Drinking Water Treatability Database (TDB) presents referenced information on the control of contaminants in drinking water. This is a summing up of the process steps: a: Prefiltration 1. Chemical treatment typically is applied prior to sedimentation and filtration to enhance the ability of a treatment process to remove particles. , 2019.
