Abstract

abstract the invention relates to a method for purifying water and for dewatering sludge, comprising the following steps: bringing a surface-treated natural calcium carbonate, a natural bentonite and an anionic polymer into contact with the water or sludge, flakes being formed as a result of the agglomeration of particulate materials contained in said water or sludge, and separating said formed flakes so as to obtain purified water, or separating water in order to obtain dewatered sludge. the surface-treated natural calcium carbonate is a product of a reaction of natural calcium carbonate with an acid and carbon dioxide, which is formed in situ by the acid treatment and/or is fed from outside, and is produced as an aqueous suspension with a ph greater than 6.0 measured at 20°c. the invention also relates to a composition comprising said surface-treated natural calcium carbonate, a natural bentonite, and an anionic polymer, for the purpose of purifying water or dewatering sludge. ---------------------------------------------------------------------------------------------- tradução do resumo resumo patente de invenção: "método e composição para a purifi-cação da água e remoção de água de lama". a presente invenção refere-se a um método para purificar a água e para remover água de lama, o qual compreende as seguintes etapas: colocação de um carbonato de cálcio natural tratado na super-fície, uma bentonita natural e um polímero aniônico em contato com a água ou lama, em que são formados flocos como resultado da aglome-ração dos materiais particulados contidos na dita água ou lama, e se-paração dos ditos flocos formados de modo a obter água purificada, ou separação da água a fim de obter lama desidratada. o carbonato de cálcio natural tratado na superfície é um produto de uma reação de carbonato de cálcio natural com um ácido e dióxido de carbono, o qual é formado in situ por um tratamento com ácido e/ou é alimentado de fora, e é produzido como uma suspensão aquosa com um ph maior do que 6,0 medido a 20°c. a invenção também se refere a uma composição que compreende o dito carbonato de cálcio natural tratado na superfície, uma bentonita natural e um polímero aniônico, para a finalidade de purificar a água ou remover a água de lama.
