How does a centralized water treatment plant work?
Centralized water treatment plantsare based on coagulation, flocculation and disinfection processes and found to be most cost-effective in treating large quantities of water. However, they entail large infrastructure costs which is difficult to raise in rural regions of developing countries and are generally installed using government funding. Hence, centralized treatment is available only in the metros of developing countries and mainly benefit the urban population. The transportation cost of water to the centralized treatment plant and from the treatment plant to the individual households is another major expense which limits its benefits to regions which are situated away from the treatment plant. Hence centralized treatment plants are generally installed near the freshwater resources (rivers or lakes) and benefit the people living closer to these water bodies.
What is centralized water treatment?
Centralized water treatment plants are based on coagulation, flocculation and disinfection processes and found to be most cost-effective in treating large quantities of water.
How is brine treated?
Treatment of the brine is conducted in a vertical tube, falling film evaporator driven by vapour compression. Wastewater is pH adjusted to between 5.5 and 6 and then heated to boiling point and deaerated. Hot brine then enters the evaporator sump where it mixes with recirculating brine slurry which is pumped to the top of 2 inch (50.8 mm) heat transfer tubes. As the slurry falls a small portion of the water evaporates and condenses on the outside of the heat transfer tubes. The brine evaporator recovers 95% of the flow which is passed on to the demineralisation feed tank with a water quality of less than 10 ppm TDS. The 5% concentrated brine then enters a crystalliser where a further 95% of the remaining water is recovered. The stream is finally sent to a filter press and dewatered to a 20% moisture content sludge which is disposed of off site.
What is the Bendigo water treatment plant?
I. Bendigo water treatment plant (BWTP). The 12.54 × 10 4 m 3/day (33 MGD) BWTP has been producing drinking water for nearly 1 million people in central Victoria, Australia since 2002. It is one of the largest if not the largest MF plant in the world. The plant combines submerged microfiltration (CMF-S), ozonation and biological activated carbon (BAC) to treat a variable and difficult raw water. Raw (surface) water is pre-screened, and dosed with lime and carbon dioxide in a contact reactor to control alkalinity and corrosion. Next, water is dosed with a coagulant, liquid aluminium chlorohydrate (ACH) prior to entering the CMF-S plant to remove colour, some organic content, and dissolved metals. The coagulant dosage is typically 5–6 mg/l. The coagulant precipitate is removed by MF. The coagulant/CMF-S process removes up to 15% of the dissolved organic carbon.64
