我在沈阳发现了一家大型纯净水设备公司，它们生产的设备可以去除水中的杂质、溶解物质和微生物，提供高纯度的水。这些设备根据不同的应用和纯度要求，可以分为几种类型：

首先，有反渗透（RO）纯水设备，这些使用反渗透膜技术来去除水中的溶解性固体、细菌、病毒等，产生高纯度的水。

其次，还有离子交换（IX）纯水设备，这些通过离子交换过程去除水中的离子，达到纯化水的目的。

然后，还有蒸馏水设备，它们利用蒸发和凝结的原理去除水中的溶解性固体、细菌、病毒等，产生高純度的water.

此外，还有电渗析（ED）pure water equipment, which uses electrodialysis membranes to remove ions from the water, producing ultra-pure water. And there are also fiber fouling membrane (UF) pure water equipment that use ultrafiltration technology to remove large molecules, suspended solids and microorganisms from the water, producing purified water. Furthermore, there are ultraviolet (UV) disinfection systems that use ultraviolet light to kill bacteria, viruses and other microorganisms in the water.

Finally, they also offer activated carbon filters that use activated carbon filter elements to remove odors, chlorine residues and organic matter from the water, providing clear filtered water.

The company offers excellent after-sales service:

They provide free storage of all design-to-production documents for 15 years.

They track the operating status of their devices lifetime and send text messages or make phone calls to remind customers when it's time to replace consumables. They also offer technical analysis services for device operation records.

If a device malfunctions within 30 minutes of notification they will provide a solution within 24 hours with on-site repair if needed.

They provide comprehensive training for at least one or two personnel responsible for operating and managing their devices after purchase completion with skill assessment following training.

Training content includes basic theory about pure drinking-water production process; construction details; operation procedures; maintenance routines; meter calibration techniques; troubleshooting methods for faults as well as practical hands-on work experience during actual site operations

The company guarantees safe stable running performance up till 15 years!

These pure drinking-water making machines can be used in laboratories medical facilities pharmaceutical factories electronic industries chemical manufacturing food processing etc., supplying clean potable H2O according to diverse needs while selecting such machinery requires consideration of desired purity level output capacity durability upkeep costs post-delivery assistance etc..
