Pure Water In Membrane Technology In The Process

Contrast to conventional pure water technique, Whole Memberane Technology has the virtue of simple operation,lower costs,good water quality.fewer chemicals ,and is an advanced pure water technology. The author has participated in the work and analysed it. I . The argument and choice of the craftThe project of Qingdao hengyuan limited company boiler replenishment water system is put into practice in this text, all kinds of water technology are argued and compared, adopting the filter +hypefilter + Reverse Osmosis + EDI project named Whole Memberane Technology.1. Comparison and choice of every kind of pretreatmentTraditional pretreatment method have variety means.This text joins together the native headwaters, hypefilter is choosed to the pretreatment craft through comparison. On the safe side, the disk filter is increased before hypefilter .This project can insure the water quality matches the follow-up equipments' request, doing not need to increase again chemistry reagent, and is the more environmental compare to traditional pretreatment method.2. Comparison and choice of every kind of remove salt craftIX is traditional maturate remove salt craft, but IX require the sour and alkali to regenerate, operation complicated, circulate expenses is high, have dirty water exhaust, automatization difficulty, result in to labor the strength big.This works select that is nowadays advanced, valid , mature salt techniqueReverse Osmosis technique.Making use of Reverse Osmosis technique can get rid of the aquatic deliquescence salt, gum, germs, virus, germs endotoxin and mostly organic matters effectively. Reverse Osmosis equipments system 's remove salt rate is 97-99% generally.3. Comparison and choice of every kind of back salt craftRemove salt craft technique primarily contain mixture ion exchange technique (MB- IX) and the continuous electricity rebirth remove salt technique ( EDI).The equipments cost of the MB- IX is lower, but consumeing the sour and alkali, the operation complicated, having the sour and alkali waste water exhaust, circulating expenses high, these characteristic can't satisfy to request to the more and more high environmental protection need of modern water handles industrial obviously.This works selected the domestic the equipments of EDI, since economized of investment, matching the environmental request, realizes the automation of the whole system, reduced the personnel's labor strength.II .The design of the Whole Memberane TechnologyProceed the design to the craft system of Whole Memberane Technology, include the craft compute, choosing the equipments and explain to design etc..III. The aqueous Whole Memberane Technology in chemistry handles craft system This text introduced the Whole Memberane Technology applyhengyuanchemistry water treatment system includes the raw water term and produce,Water request, craft process, gauge and control system etc. and the characteristics , in-water request and its technique parameter of is introduced.IV. The craft practiceThis text introduced the Whole Memberane Technology craft practice process the circumstance of the equipments installation,adjust,and run.Compare to and analysis large quantity of the data, the virtue and advanced of the craft is accounted for from pretreatment system, Reverse Osmosis, EDI.From circulate circumstance, Whole Memberane Technology craft is a kind of advanced, dependable, environmental water handles technique.
