Thermo Scientific D12681 反滲透系統(tǒng)

吸附

活性炭與供給水中的氯和有機(jī)材料來固定和去除這些雜質(zhì)。

去離子作用

去除離子和交換樹脂的合成的離子礦物質(zhì)陽離子樹脂去除帶正電的離子,陰離子樹脂去除帶負(fù)電荷的離子。

蒸餾

水加熱過程為氣態(tài)，再濃縮在一個單獨的容器里，并重新凝結(jié)。

過濾

作為預(yù)處理過濾使用，或一個獨立的處理。正常管路壓力下，水通過過濾器指定的孔隙。過濾器保留了大部分的顆粒物，與水通過

反滲透

使用主要作為預(yù)處理。通過的半透膜U型管分離等量的純凈水和鹽溶液，。當(dāng)外部壓力施加到鹽水側(cè)，半透膜允許水通過，而鹽濃縮沖進(jìn)下水道。

超濾

用于去除熱原質(zhì)和細(xì)菌。在壓力下，水被強(qiáng)制通過膜用孔徑小于0.005 IM。顆粒被截留，只有純凈水通過

紫外線（UV）氧化紫外燈

（<280納米）通過破壞細(xì)菌，病毒和痕量有機(jī)物的水。

Adsorption

Activated carbon bonds with the chlorine and organic materials in feedwater to immobilize and remove these impurities.

Deionization

The removal of ions and minerals by synthetic ion exchange resins. Cation resins remove positively charged ions; anion resins remove negatively charged ions.

Distillation

The process in which water is heated to a gaseous state and recondensed in a separate vessel.

Filtration

Use as a pretreatment or a stand-alone treatment. Water passes through a filter of specified porosity at normal line pressures. The filter retains most particulates, with water passing through.

Reverse Osmosis

Use primarily as a pretreatment. Equal amounts of pure water and saline solution are separated in a U-tube by a semipermeable membrane. When external pressure is applied to the saline side, the semipermeable membrane allows water to pass through while salts are concentrated and flushed down

a drain.

Ultrafiltration

Use for removing pyrogens and bacteria. Under pressure, water is forced through a membrane with a pore size smaller than 0.005 ìm. Particulates are retained, with only pure water passing through.

Ultraviolet (UV) Oxidation

UV light (at <280 nm) passes through the water destroying bacteria, viruses, and trace organics.
