Method and apparatus for disinfecting a refrigerated water cooler reservoir

InactiveUS7640766B2Increase airflowInexpensive to fabricateWater treatment parameter controlDomestic cooling apparatusStreamflowOzone generators

A method and apparatus for providing sanitized water in a cabinet and spigot type bottled water dispenser features an ozone generating system to generate ozone for sanitizing the water. Ozone is generated and collected within an ozone generator housing. A blower transmits air to the ozone generator housing. The air carries the ozone that is generated through a flow line to an air diffuser that is positioned upstream of the spigot (or spigots) used to dispense water. In one embodiment, a valve that is activated on the spigot to dispense water also activates the blower and ozone generator. In other embodiments, a flow sensor activates the ozone generator and blower. Various spigot and flow sensor arrangements are disclosed as a part of the overall apparatus and method.

PVC mother liquor recycling treatment device and process

PendingCN114105346AEmission reductionHigh quality recyclingGeneral water supply conservationTreatment involving filtrationReverse osmosisProcess engineering

The invention belongs to the technical field of environmental protection, and particularly relates to a PVC mother liquor recycling treatment device and process. The device comprises a PVC mother liquor pipeline, the PVC mother liquor pipeline is sequentially connected with an advanced oxidation reactor, a buffer sedimentation tank, a ceramic membrane filter, a heat exchanger and a reverse osmosis desalting device, a concentrated water outlet of the reverse osmosis desalting device is connected with the ceramic membrane filter through a backwashing pump, and the ceramic membrane filter and the advanced oxidation reactor are both connected with an ozone generator; the PVC mother liquor directly enters a Fenton + ozone advanced oxidation reactor without cooling, Fenton-ozone advanced oxidation is carried out, then a ceramic membrane filter is adopted for ceramic membrane filtration, after heat exchange, filtered water is directly subjected to reverse osmosis desalting treatment, produced water is recycled, and concentrated water is used for backwashing the ceramic membrane filter. According to the method, high-quality recovery of the PVC mother liquor can be realized, the COD discharge amount and the water taking amount of a factory are reduced to a great extent, and the benefits of PVC production enterprises can be effectively increased.
