      現在社會水污染很嚴重,人們對于水的要求也提高了很多,全自動反滲透純水處理設備超濾膜選型也就變得尤為重要,: 一般來說,超濾膜是一種孔徑規格一致,額定孔徑范圍為0.01微米以下的微孔過濾膜。大多用于純水處理、分離、濃縮、純化生物制品、醫藥制品以及食品工業中,今天技術人員主要為您講述全自動反滲透純水處理設備超濾膜的保養方法和應用方法。 全自動反滲透純水處理設備超濾膜的清洗步驟:

      Nowadays, water pollution is very serious in society, and people's requirements for water have been raised a lot. Ultrafiltration membrane selection of fully automatic reverse osmosis water treatment equipment has become particularly important. Ultrafiltration membrane is a kind of microporous membrane with uniform pore size and rated pore size of less than 0.01 micron. Most of them are used in pure water treatment, separation, concentration, purification of biological products, pharmaceutical products and food industry. Today, technicians mainly tell you about the maintenance methods and application methods of ultrafiltration membrane of fully automatic reverse osmosis water treatment equipment. Cleaning steps of ultrafiltration membrane for fully automatic reverse osmosis water treatment equipment:

      1、先用清水沖洗整個超濾(能截留0.002-0.1微米之間的大分子物質和蛋白質)系統,水溫采用反滲透(借助于半透過膜的膜分離技術)膜組件所能承受的較高溫度

      1. Rinse the whole UF system with clean water (which can intercept macromolecular substances and proteins between 0.002 and 0.1 microns). Water temperature is higher than that of membrane module by reverse osmosis (with the help of semi-permeable membrane separation technology).

      2、選用合適的清洗劑進行循環清洗水處理設備:飲用水列表,清洗劑中可含EDTA或六偏磷酸鈉等絡合劑。

      2. Choose appropriate detergent for circulating cleaning water treatment equipment: drinking water list, detergent can contain EDTA or sodium hexametaphosphate complexing agent.

      3、用清水沖洗,去除清洗劑。

      3. Rinse with clean water to remove the detergent.

      4、在規定的條件下校核膜的透水能量,如未能達到預期數值時,重復步驟。

      4. Check the permeability energy of the membrane under specified conditions. Repeat steps if the expected value is not reached.

      5、用百分之0.5的甲醛水溶液浸泡消毒(指殺死病原微生物、但不一定能殺死細菌芽孢的方法)并貯存。

      5. Immerse in 0.5% formaldehyde solution for disinfection (refers to the method of killing pathogenic microorganisms, but not necessarily killing bacterial spores) and storage.

      在超濾膜兩側存在壓力差的情況下,當自來水流過膜表面時,超濾膜表面密布的許多細小的微孔(每米長的超濾膜絲管壁上分布有約60億個0.01微米的微孔)只允許水分子及小分子物質(有益礦物質和微量元素)通過,而體積大于微孔直徑的物質(細菌、膠體、鐵銹、懸浮物、泥沙、大分子有機物的直徑都大于細菌)則被截留,從而實現對自來水的凈化的效果。

      In the case of pressure difference between the two sides of the UF membrane, when tap water flows through the membrane surface, many tiny pores (about 6 billion 0.01 microns on the wall of the UF filament tube per metre) are densely distributed on the surface of the UF membrane. Only water molecules and small molecules (beneficial minerals and trace elements) are allowed to pass through, but the volume is larger than that of the micropore. The diameter of substances (bacteria, colloids, rust, suspended solids, sediment and macromolecular organic matter are all larger than bacteria) are intercepted to achieve the purification effect of tap water.

      全自動反滲透純水處理設備運行不妥對超濾膜的影響:

      The influence of inappropriate operation of automatic reverse osmosis water treatment equipment on ultrafiltration membrane:

      1、純水處理而言,超濾膜元件的損壞大半是發生在元件裝填及運行初期。因為設備是較嚴謹的產品,很容易遭受機械性損壞。

      1. As far as pure water treatment is concerned, most of the damage of UF membrane components occurs in the initial stage of component loading and operation. Because the equipment is a more rigorous product, it is vulnerable to mechanical damage.

      2、全自動反滲透純水處理設備設計的不正確或誤操作造成膜會受到損傷導致超濾膜性能下降,這樣的損傷造成的性能惡化是很難被恢復的。

      2. Ultrafiltration membranes will be damaged due to incorrect design or incorrect operation of fully automatic reverse osmosis water treatment equipment. The deterioration of Ultrafiltration membranes caused by such damage is very difficult to recover.

      3、超濾膜運行中發生的故障:這一般是由于錯誤的運行狀態引起會導致產水流量下降,只要重新設定正確的運行狀態就可以恢復。

      3. Ultrafiltration membrane faults occurring in operation: This is generally due to the wrong operation state, which will lead to the decline of water flow, as long as the correct operation state is reset, it can be restored.

      通過上述介紹,想必您已經了解全自動反滲透純水處理設備超濾膜分清洗保養方法了,如果清洗不到位,不僅減少設備壽命,也影響了水質量,更多內容聯系重慶碧純凈化設備有限公司,讓我們為您詳細講述。

      Through the above introduction, you must have known the maintenance method of ultrafiltration membrane cleaning for fully automatic reverse osmosis water treatment equipment. If the cleaning is not in place, it not only reduces the life of the equipment, but also affects the quality of water.
