HATENBOER-WATER過(guò)濾器HDN系列介紹
HDN中和過(guò)濾器
為海水淡化裝置生產(chǎn)的水的調(diào)理選擇各種中和過(guò)濾器。使用這些過(guò)濾器可以改善水的口感，并防止自來(lái)水系統(tǒng)的腐蝕。
低pH值水
低pH值的水，例如來(lái)自海水淡化廠（包括蒸發(fā)器和反滲透水機(jī)）的產(chǎn)品水，通常具有腐蝕性且無(wú)味。這種所謂的“酸性狀態(tài)”是由于游離二氧化碳?xì)怏w（CO2）的存在以及天然礦物質(zhì)的缺乏。
中和/礦化
為了使這種水中性或略呈堿性，應(yīng)進(jìn)行中和或礦化處理。為了確保完全去除CO2，可以通過(guò)一床中和過(guò)濾介質(zhì)“EWT化合物”過(guò)濾水。在低壓過(guò)濾過(guò)程中，CO2與EWT化合物反應(yīng)，形成天然的碳酸氫鹽和鈣（Ca2+）。這兩種離子都能減少水的腐蝕性。
EWT化合物
過(guò)去，常用大理石中和（礦化）方法，但這種反應(yīng)速度較慢，難以達(dá)到并維持平衡。如今更傾向于使用EWT化合物，因?yàn)樗磻?yīng)迅速且完全。其特殊結(jié)構(gòu)使其能快速且均勻地溶解。
EWT化合物是一種顆粒狀介質(zhì)，裝在25公斤的袋子中。平均使用量為每70立方米水用1公斤（2磅）。每年可以部分補(bǔ)充幾次，以補(bǔ)充在此過(guò)程中溶解在水中的材料。在補(bǔ)充時(shí)，必須反向沖洗過(guò)濾器，以清除灰塵和污染物。此外，還建議偶爾沖洗濾床，以松動(dòng)濾料。
材料
HDN GRP過(guò)濾器由100%復(fù)合玻璃纖維防腐材料制成，內(nèi)殼為聚乙烯，具有防腐蝕性能。
管道
HDN GRP過(guò)濾器配備PVC-U管道和手動(dòng)（三通）球閥，以實(shí)現(xiàn)全操作，包括中和過(guò)濾器的反沖洗。管道直徑取決于過(guò)濾器型號(hào)。

neutralising filters
Choose from a wide range of neutralizing filters for the conditioning of water produced by desalination installations. Use these filters for improved taste and prevention of corrosion in your freshwater system.
Low pH
Water with a low pH value, such as product water from desalination plants (both evaporators and reverse osmosis type water makers), is often corrosive and tasteless. This so-called ‘a(chǎn)cid condition’ is due to the presence of free carbonic acid gas (CO2) and a lack of natural minerals.
Neutralising / mineralising
To make this water neutral or slightly alkaline, it should be neutralized or mineralized. To ensure complete removal of CO2, the water can be filtered through a bed of neutralizing filter media, named “EWT compound.” In the low-pressure filtration process, the CO2 reacts with the EWT compound to form natural bicarbonates and calcium (Ca2+). Both ions will contribute to less corrosive water.
EWT compound
In the past, it has been common practice to use marble neutralizing (mineralizing), though the reaction is slow and equilibrium is difficult to reach and maintain. EWT compound is now preferred due to its quick and complete action. Its special structure makes it rapidly and uniformly soluble.
EWT compound is a granular medium, packed in 25 kg bags. The average consumption of material is 1 kg (2 lb) on 70 m3 of water. It is sufficient to partially refill a few times per year to replace the material that has been dissolved in the water in due process. Upon refilling, the filter must be flushed by reversing the water flow to remove dust and contamination from the fresh filling material. We would furthermore advise you to occasionally flush the filter to loosen the filter bed.
Material
The HDN GRP filters are made of 100% composite fiberglass corrosion-resistant material with a polyethylene inner shell and are corrosion-resistant.
Piping
The HDN GRP filters are supplied with PVC-U piping and manual (three-way) ball valves for full operation, including backwash of the neutralizing filter. The piping diameter is dependent on the filter model.
