Disclosed is a flocculating agent which is reactive in a neutral pH range, can render the pH of a water treated with the flocculating agent neutral, can be handled simply, and is particularly useful for the effective clarification of a mud water. The flocculating agent is in the form of a powder, shows a pH value ranging from 5 to 9 when added to pure water, and comprises an acidic powder which comprises a porous particle having a metallic component adsorbed thereon and an alkaline powder which comprises a porous particle having potassium phosphate adsorbed thereon, wherein the flocculating agent contains both of the powders in a mixed state.
