PURPOSE:To improve reclamation yield, by a method wherein, by the use of a sludge agglomerating sinking agent, consisting of an organic agglomerating sinking agent, calcium carbonate, and calcium hydrooxide, sludge is rapidly sunk to form sludge having high compacting properties. CONSTITUTION:By the use of a sludge agglomerating sinking agent, consisting of an organic series agglomerating sinking agent, calcium carbonate, and calcium hydroxide, sludge is rapidly sunk to separate the sluge from water, the moisture content of the sludge is reduced to form sludge having high proper ties, and this improves reclamation yield. In which case, acryl amide.carboxymethylcellulosegraft polymer, polyacrylamide, acrylic acid.acrylamide coploymer, alginic acid soda are listed as the organic agglomer ating sinking agent. |
