A necessidade de purificação da água foi percebida pelo homem nos estágios iniciais da civilização. Por isso, o governo central e estadual estão envidando esforços para fornecer água potável adequada e segura à população, construindo estações de tratamento de água no paÃs. O processo de filtração sofre degradação na fase inicial e final, o que afeta a qualidade inicial do efluente do filtrado após a retrolavagem. O filtro rápido de areia é uma unidade importante da estação de tratamento de água, que remove os flocos e colóides por meio da filtração. Após a retrolavagem do filtro, quando o filtro rápido de areia é colocado de volta em operação normal, observa-se uma alta turbidez inicial do filtrado. Ela se apresenta na forma de um pico de turbidez. Para reduzir esse pico de turbidez, o condicionamento do filtro é essencial. O presente estudo é para o condicionamento do filtro rápido de areia usando coagulantes como alúmen e polÃmero em diferentes percentagens durante a retrolavagem do filtro rápido de areia. A dosagem ideal, bem como os pontos de aplicação correspondentes durante a retrolavagem, serão determinados com base em estudos em escala laboratorial que constataram uma melhoria na qualidade inicial do efluente do filtro rápido de areia.
