Wastewater can originate from a combination of domestic, industrial, commercial or agricultural activities, surface runoff or storm water, and from sewer inflow or infiltration. That is the reason for the surge in Water Treatment Plant & Equipments and this is where we, at Doctor Water comes in to picture. Water is used for drinking, washing, cleaning, and many other purposes in the household. Continuous chlorination is a point-of-entry treatment method that can offer residual disinfection throughout the household water distribution system. The e-learning session 'Transforming wastewater treatment with TOC monitoring' will explore how this parameter can be used to further optimise performance for wastewater plants. One such criteria is the water's organic load, which can be monitored using the Total Organic Carbon in the water. It involves screening to remove large objects such as sticks, stones etc which can cause damage to tank inlets. HOUSEHOLD WATER TREATMENT FILTERS PRODUCT GUIDE 1 1 Introduction The provision of safe drinking water for all, in sufficient quantities, is a key priority for UNICEF and other water, sanitation and hygiene (WASH) actors, be it at the onset of an emergency or in a protracted crisis.
