Filtration of organic suspensions. |
摘要 |
<p>An organic suspension, such as sewage sludge, is conditioned by adding a conditioner and then filtering the suspension through a filter element to form a filter cake on the element. Improved dryness properties of the cake are obtained by using as conditioner during the formation of at least the first half (by weight solids), but not all, of the cake a high molecular weight polyelectrolyte conditioner and by using as conditioner during the formation of the remainder of the cake an inorganic conditioner or a low molecular weight polyelectrolyte conditioner.</p> |
