Several questions about water treatment – prize available
Thread Content
Since I am planning to deepen my knowledge of water treatment, I have come to ask the more experienced colleagues for advice: what are the suitable water treatment methods for power plants at present? Which ones are more advanced, and which ones are under development? I hope everyone can give me lots of advice! Thank you first!
Power plant water treatment should be configured according to needs, and it can be divided into three main categories: 1. Traditional water treatment methods, such as clarifiers, valveless filters, inclined plate filters, conventional pressure filters (such as sand filters and carbon filters), resin softeners, or exchangers ；
2. It refers to the membrane treatment technologies that have been in use since the 1970s, with reverse osmosis membrane technology being a representative example ； 3. These are the EDI or CDI technologies that were widely implemented starting in the late 1990s, as well as the MBR technology based on ultrafiltration membranes.
Cleaning of the circulating water system in the new system: Should the packing in the cooling tower be covered?
As far as I know, thermal power plants basically use membrane processes, such as ultrafiltration or reverse osmosis. It is not clear what type of water treatment is used in nuclear power plants. The principles behind these water treatment methods are already well-established; what is considered advanced or still under development is mostly related to automation. Therefore, it is recommended not to get too fixated on the technical aspects, and it would be better to think more broadly.
Is it sewage treatment or water treatment?
When cleaning the circulating water system of the new system, the cooling tower should not be activated first to avoid contaminating the packing
The treatment methods used in power plants can be summarized into three approaches: ① The most common method is to remove some or all of the impurities from the raw water in order to achieve the desired water quality； ②Obtaining the desired water quality by adding new components to the raw water ； ③The treatment of raw water does not involve the removal of impurities or the addition of new components. Physical-chemical water treatment methods are applied to the make-up water for power plant boilers. Among the more advanced methods is the automatic water treatment system that involves the addition of ammonia and hydrazine to power plant boilers ； What is currently being developed and tested is: a standard method for determining the working exchange capacity of ion exchange resins used in power plant water treatment
The advanced water treatment technology for power plants should be RO+EDI
Power plant water treatment includes raw water treatment, boiler water treatment, circulating water treatment, and wastewater treatment; depending on the process used, ash flushing water treatment may also be required. The appropriate treatment method must be chosen based on specific circumstances, and it cannot be explained simply in a few words
