Ultra Pure Water Equipment

Ultra pure water equipment

Industrial reverse osmosis device

Nearly complete removal of the conductive medium in the water, and the water does not dissociation of colloidal substances, gases and organic matter are removed to a very low degree of water. The resistivity is greater than 10 ~ *cm 18.3M limit value. Ultra pure water, pure water machines and equipment in general difficult to achieve, usually by pre treatment, reverse osmosis technology, ultra purification treatment and after treatment of four steps, multi-stage filtration, high performance ion exchange (polished), ultrafiltration filter and UV lamp, in addition to the TOC device, such as a variety of treatment methods, the resistivity up to 18.25M Omega column with a?

The process of preparing industrial ultra pure water is roughly divided into the following:

(1)Traditional water by ion exchange resins in the preparation of ultra pure water treatment, the main process: raw water, sand carbon filter, precision filter, Yang bed, anion bed, mixed bed (double bed), pure water tank, water pump, post precision filter, water ?

(2)By use of reverse osmosis water treatment equipment and ion exchange equipment combination way and the main process: raw water, sand carbon filter, precision filter, reverse osmosis equipment, pure water tank, the mixed bed (double bed), ultra pure water, ultra pure water pump, post precision filter, water?

(3)Preparation technology of reverse osmosis water treatment equipment and electrodeionization (EDI) equipment to match the way, which is a preparation of ultra pure water of the latest technology and environmental protection, economic, development potential huge super ultrapure water and the main process: raw water, sand carbon filter, precision filter, anti penetration equipment, pure water tank, electrodeionization (EDI), ultra pure water, ultra pure water pump, post precision filter, water?

Three preparation industry with ultra pure water process is the preparation of electronic industry with ultra pure water technology is more than three, the rest of the process is mostly on the basis of the above three kinds of basic process of different combination collocation derivative?

The advantages and disadvantages of them are listed below:

(1)The first ion exchange resin has the advantages of less initial investment, less occupied place, but the drawback is that the need to often carry out ion regeneration, consuming a large amount of acid and alkali, and the environment has a certain damage?

(2)Second using reverse osmosis as pretreatment with ion exchange equipment and its characteristics for early investment than by ion exchange resin is higher, but equipment ion regeneration cycle is relatively long, the consumption of acid and alkali than simply using ion exchange resin to a lot less. But there is a certain damage to the environment.?

(3)The third kind of the reverse osmosis pretreatment and then with electrodeionization (EDI) device, which is currently producing ultra pure water the most economical, most environmental protection for the production of ultra pure water process, do not need to regenerated with acid and alkali can be continuously producing ultra pure water, not what destructive to the environment. The disadvantage is that the initial investment is too expensive in two ways.
