摘要： This invention relates to method of utilising a waste slurry from silicon wafer production. More specific, this invention relates to a method for utilising the solid fraction of the slurry, which stems from the sawing or slicing of silicon wafers as a raw material in other industrial processes such as production of certain ceramics, such as silicon nitride bonded silicon carbide and/or silicon bonded silicon carbide.

摘要： The present invention relates to a method for removing a silicic compound from the waste liquor of steel pickling. A filtering method using a filter fabric or biscuit plate is impractical as an industrial method because the filtering medium becomes clogged.
The present invention is characterized by an adsorption method in which silicic compounds are adsorbed on adsorbent substrates (3) in an optional part of an adsorption bed.
The present invention is characterized in that the waste liquor is passed through the adsorption bed for a two-month period or longer without clogging occurring.

摘要： Disclosed is an economical process for the purification of water containing soluble and sparingly soluble inorganic compounds using single-stage or two-stage membrane processes that integrate membrane water purification with chemical precipitation softening and residual hardness and silica removal from the membrane concentrates using ion exchange resins and silica sequestering media, respectively. The purified water recovery in the present invention will not be adversely affected by design and/or operational deficiencies in the chemical precipitation softening system that may result in higher residual hardness and silica in the supernatant from the clarifier
