① 5、科學家利用太空中的廢水變成飲用水採用的技術是： A.滲透法 B.反滲透法 C.蒸餾法 D.提純法
答案：A滲透法
太空水是採用AO膜處理技術對自來水進行終端凈化後專的水 .膜處理技術是目前最成屬熟的水處理技術，來源於宇航員在飛船上獲得飲用水的原理。採用這種方法處理後，細菌、病菌、重金屬等肉眼看不到的有害物質都被排除在膜外。
② 安潔爾J1205-ROB8C型反滲透凈水器怎麼裝
如果想咨詢安裝，建議你通過網路找到豪特住宅科技咨詢，讓它們安排專業工程師和你溝通，指導你進行安裝，以免發生漏水及裝錯！
③ 看中了沁園405C凈水器，但是聽說反滲透凈水器會產生很多廢水，該怎麼辦
你說的這款產生廢水不多。這款有變頻節水技術，水滲透率挺高的，在水質好的情況下，2杯凈水1杯廢水，若水質情況不佳，生產1杯凈水也只會產生1杯廢水。
④ 美的反滲透凈水器MRO121C-4怎麼樣
您好，要看凈水機的好壞，就要看它RO膜的過濾精度是多少，最好是0.0001微米。
⑤ 水處理設備中的C是什麼意思
萊特萊德為您解答：何物質都有自己固有的頻率，水垢屬於無機鹽類，一般設備的外殼都是金屬材料製作，水垢和金屬材料的振盪頻率不同。SLGP型電子水處理儀釋放的高頻振盪波對於附著在金屬材料表面的水垢產生共振，即擊碎剝離，由表及裡，循環進行，從而達到除垢的效果。
水是人類發展不可缺少的自然資源，是人類和一切生物賴以生存的物質基礎。當今世界，水資源不足和污染構成的水源危機已成為任何一個國家在政策、經濟和技術上所面臨的復雜問題和社會經濟發展的主要制約因素。
在水資源日益缺乏的情況下，水資源污染的現實又使人們增加了一份憂慮。在中國很多地區，由於各種復雜因素致使不少水體已經嚴重受到污染，這更加劇了水資源緊缺的矛盾。
工作原理
RO-反滲透預處理工藝主要為活性炭和精濾。滲透是一種自然現象：水通過半透膜，從低溶質濃度一側到高溶質濃度一側，直到溶劑化學位達到平衡。平衡時，膜兩側壓力差等於滲透壓。這就是滲透效應(Osmosis)現象。反滲透是指如果在高濃度的一邊加壓，便能把以上提及的滲透效應停止並反轉，使水份從高濃度迫往低濃度的一邊，把水凈化。這種現象稱為反滲透(逆滲透)，這種半透膜稱為逆滲透膜。
設備特點
反滲透水處理設備能過濾掉水中的細菌、病毒、重金屬、農葯、有機物、礦物質和異色異味等，是一種純水，無需加熱即可飲用。它所過濾出的水量的成本很低。生產的純水品質高、衛生指標理想。
反滲透水處理設備是採用先進的反滲透除鹽技術來制備去離子水，是一種純物理過程的制備技術。反滲透純水機組具有能長期不間斷工作，自動化程度高，操作方便，出水水質長期穩定，無污染物排放，製取純水成本低廉等優點。反滲透膜技術在國內醫葯、生物、電子、化工、電廠、污水處理等領域得到了廣泛的運用。
⑥ 反滲透法是淡化海水制備飲用水的一種方法，若25°c時用密度為1021千克每立方米的海水提取淡水，應在海水
您可以參考一下相關的膜手冊。在含鹽量在三萬的情況下，我個人認為有4Mpa就可以產淡水，但淡水產出的多少取決於濃水側所加壓力的大小。

c. RO unit (membrane array)
RO unit is the actuator of the whole desalting system, whose role is to remove soluble salts, colloids, organic compounds, and microorganisms in the water. The unit is equipped with three set ROs, each has 219m3/h net output, more than 75% recovery rate, and more than 97% total desalting rate (within the life-term). RO membrane adopts TML20-370 anti-contamination RO membrane element proced by Japan Toray Company [Length: 40〃; Diameter: 8〃; Membrane area: 370 square feet (34 m2); Single membrane desalting rate: 99.5%]. Each set RO adopts design of two-sections per grade (需要自己核實) and 62 seven-meter-long pressure containers lining in 41:21 matrix, each pressure container is internally equipped with seven membranes, thus each RO set needs 434 membranes and a total of 1736 membranes for 4 sets. The mean membrane flux is 14.7LMH being in accordance with super-filtration water RO design guideline and having large margins.
c. RO cleaning unit
RO pressure is generally operating at 1.3-1.8MPa. After long-term running, RO membrane array may be contaminated by some contaminations uneasy to be washed off, for example, long-term accumulation of trace salt scales and some organic compounds can result in declining of the performance of the membrane moles and higher running pressure, and therefore, RO membrane array must be cleaned with some chemicals to recover its normal desalting function. When super-filtration was used as pretreatment, it should be cleaned every 3 months, and every cleaning lasts about 2-4 hours. The unit is equipped with a set of cleaning equipment including a stainless steel safeguard filter, two cleaning pumps (1 in use & 1 for preparation) and a cleaning agent tank. The cleaning unit is operated automatically.
d. RO washing unit
RO system is equipped with automatic washing unit, which washes the membrane element surface with RO-proced water as supply to avoid contamination sediment on the membrane surface. The unit is equipped with two wash pumps (1 in use & 1 for preparation) and a washing tank.
e. Control instrument
Serials of online measuring instruments are equipped to control and monitor the normal running of RO system, including conctivity instrument, flow meter, pressure meter, sampling apparatus, and high-low voltage protecting switch, etc. RO is operated automatically, whose condensed water discharging flow is fixed according to the steady-flow-valve installed in the pipelines, and the proced water is set with high-pressure proof bursting membrane.
