专利汇可以提供Closed recycling system for water purification and waste reduction专利检索，专利查询，专利分析的服务。并且A waste purification and reduction, water purification and recycling process comprises collecting and storing household, commercial or industrial waste, homogenizing the waste and reducing the solid content thereof to uniform fine particle size, injecting the homogenized waste through an atomizing nozzle, cryogenically freezing the atomized waste into crystalline particles of uniform size, centrifugally separating the crystals into water crystals and light and heavy solid waste crystals, heating the water crystals to steam and condensing the steam to water, incinerating the solid waste crystals to combustion gas and ash, venting the combustion gas and collecting the ash. In another embodiment of the process, the water vapor in the atomized waste is removed by vacuum prior to freezing. The water vapor is heated to steam and the cryogenically frozen solid waste crystals are incinerated to combustion gas and ash, after which the gas is vented and the ash is collected.，下面是Closed recycling system for water purification and waste reduction专利的具体信息内容。
