A method is provided for the treatment of water containing micro-algae wherein the water is contacted with carbonaceous fines to adsorb micro-algae onto particles of the carbonaceous fines. The carbonaceous fines may be coal or charcoal fines or mixtures thereof. The carbonaceous fines may be pre-treated to remove any unsuitable or valuable materials therefrom; or to produce suitable size ranges of particles for one or more purposes selected from facilitating adsorption; handling of the carbonaceous fines both before and after adsorption of the micro-algae; and separation of the carbonaceous fines with adsorbed micro-algae thereon. The method may target the beneficiation of carbonaceous fines and the carbonaceous fines together with the adsorbed microalgae thereon may be subjected to an agglomeration process for the production of agglomerates such as briquettes or pellets. The method may target the upgrading of a polluted water system in a commercial water treatment process.
A method for the treatment of water containing micro-algae in order to remove at least a part of the micro-algae therein, the method being characterized in that it includes contacting carbonaceous fines with such water under conditions that permit adsorption of micro-algae onto particles of carbonaceous fines and separating carbonaceous fines together with adsorbed micro-algae thereon from the water wherein the carbonaceous fines are loaded with microalgae adsorbed thereon to an amount of from 1% to 25% algae by weight of the carbonaceous fines.
