La necessità di purificare l'acqua è stata compresa dall'uomo sin dalle prime fasi della civiltà . Pertanto, il governo centrale e quello statale si stanno impegnando per fornire acqua potabile adeguata e sicura alla popolazione attraverso la costruzione di impianti di trattamento dell'acqua nel paese. Il processo di filtrazione subisce un degrado nella fase iniziale e finale che influisce sulla qualità iniziale dell'effluente del filtrato dopo il controlavaggio. Il filtro a sabbia rapido è un'unità importante dell'impianto di trattamento delle acque che rimuove i fiocchi e i colloidi attraverso la filtrazione. Dopo il controlavaggio del filtro, quando il filtro a sabbia rapido viene riportato al normale funzionamento, si osserva un'elevata torbidità iniziale del filtrato. Si presenta sotto forma di picco di torbidità . Per ridurre questo picco di torbidità è essenziale il condizionamento del filtro. Il presente studio riguarda il condizionamento del filtro a sabbia rapido utilizzando coagulanti come allume e polimeri in percentuali diverse durante il controlavaggio del filtro a sabbia rapido. Il dosaggio ottimale e i corrispondenti punti di applicazione durante il controlavaggio saranno determinati sulla base di studi su scala di laboratorio che hanno riscontrato un miglioramento della qualità iniziale dell'effluente del filtro a sabbia rapido.
