<p>PROBLEM TO BE SOLVED: To provide a friction-reducing coat formation agent which can reduce friction of water-containing particles/muddy matter coming in contact with the container wall effectively with a reduced amount of agents, in a sludge treatment of water treatment sludge and other sludges, and a method of treating treatable water-containing particles/muddy matter by preventing adhesion and clogging of water-containing granules to the container wall in treating the water-containing particles/muddy matter, e.g. storage or carrying, by using the friction-reducing agent.SOLUTION: Film formation coats 11 and 12 of water-soluble polymer are formed on a container wall 2 of e.g. a hopper 1 or a loading space 2 of a dump truck 3 by using a friction-reducing film formation agent comprising a powder water-soluble polymer, a powder acid, powder carbonate/bicarbonate and a powder neutral salt to reduce friction with water-containing particles/muddy matter 4 and 5. The water-containing particles/muddy matter 4 and 5, e.g. a sludge dehydrated cake, is supplied from a cake storage tank 6, and a storage or carrying treatment is carried out. The friction-reducing film formation agent comprises 10-90 wt.% of the powder water-soluble polymer, 10-20 wt.% of the powder acid, 1-30 wt.% of the powder carbonate/bicarbonate and 1-70 wt.% of the powder neutral salt.</p> |
