| Select inhibitors provide excellent oxidation protection and resistance to the formation of harmful sludges or acids. |
| Thus, the present invention advantageously avoids the production of tailings sludges caused by clay dispersion. |
| Detergent-dispersant additives, for instance, suspend sludges and remove them from the sliding surfaces of internal-combustion engines. |
| Incinerators are designed to destroy gases, liquids, solids, sludges, and slurries at high temperatures. |
| The settled sludges are removed, returned to the beginning of the secondary treatment process, and added to the incoming waste water. |
| Food waste, process waste and non-hazardous sludges are some examples of waste streams where there are serious difficulties, Dr Kelly said. |
