This valuable experience has enabled us to develop our expertise concerning end-user applications, such as biology, biochemistry, microbiology and immunology, and to design top-quality water purification solutions dedicated to feeding clinical analyzers.The Milli-Q ® CLX 7000 Series is manufactured in an ISO ® 9001- and ISO ® 14001-registered site. Additionally, to ensure efficiency and safety ofoperation, systems are CE-, cULus-, and FCC-certified. Furthermore, to reduce environmental impact, the Milli-Q ® CLX 7000 Series follows European Restriction of Hazardous Substances (RoHS) and Waste Electricaland Electronic Equipment (WEEE) directives.Contact your local Merck office for information about the service offer available for your facility, or visit /milli-qservices4® technology purification stepsElix ® module: Our unique technology is based on anion-permeable and cation-permeable membranes and high-quality, ion-exchange resin.Water produced by the Elix ® module enters the reservoir with resistivity greater than 5 MΩ·cm @ 25 °C (typically up to 15 MΩ·cm @ 25 °C).*The Milli-Q ® CLX 7000 Series relies on complementary water purification techniques, including state-of-the-art Elix ® electrodeionization (EDI) technology, to ensure production of consistently high quality water meets CLRW standards – at low and predictable running costs.In the Milli-Q ® CLX 7000 Series, potable tap water is first treated with a Progard ® pack and purified by reverse osmosis (RO) to remove up to 99% of contaminants. The resulting RO permeate water then enters the Elix ®Bacteria and their by-products interfere with chemistry assays and enzyme immunoassays, typically leading to unstable analyzer calibrations, high absorbance of blanks, reference drifts, and errors on mean patient values.In the Milli-Q ® CLX 7000 Series, UV lamp sanitization occurs at three stages:• During water production , a 254 nm bactericidal UV lamp inactivates bacteria.• In the tank , a UV lamp (ASM, Automatic Sanitization Module) regularly irradiates stored water and the tank walls, preventing bacterial growth and the formation of biofilm.* When CO dissolved in feed water is less than 30 ppm.5Optimize water consumption with an environmentally responsible system containing E.R.A.® technologyMilli-RX™ system(1992)Elix system (2003) with RO recovery loop Today’s Mili-Q CLX 7000Series system with E.R.A. technology10000m 900080007000600050004000300020001000WASTE (m )CLRW (m )Over the last 25 years, we have dramatically reduced water purification system water consumption, enabling laboratories to save up toseveral thousand dollars per year on tap water expenses . The graph shows water consumption and the split between CLRW produced and reject water for three of our water purification systems over a seven-year period (production of 1000 L/day of CLRW-quality water, 312 days per year).The Milli-Q ® CLX 7000 Series incorporates our E.R.A.® (Evolutive Reject Adjustment) technology — providing users with even greater savings.With its innovative and efficient reverse osmosis (RO) recovery loop, the Milli-Q ® CLX 7000 Series optimizes water consumption by recycling part of the waterrejected to the drain, thus reducing water waste and also extending RO cartridge and Progard ® pack lifetimes.Furthermore, depending on the feed water qualityanalysis, the Milli-Q ® CLX 7000 Series will calculate the best water recovery and will automatically optimize water consumption by means of motorized valves.No matter what the feed water temperature, inlet pressure, or conductivity may be, E.R.A.®technology’s automated valves ensure that the Milli-Q ® CLX 7000 Series flow rate and water recovery remain constant.* Users no longer need to manually adjust valves to maintain production flow rate and protect RO cartridge lifetime.These latest RO technologies illustrate our dedication to developing environmentally responsible waterpurification solutions to reduce tap water and system consumables use. The solutions reduce maintenance time, as well as the risk of human error — letting users save money on system operation, and also enjoy peace of mind with higher reliability, and optimized water purification system/analyzer uptime.* Please refer to Feed Water Requirements in the Specifications Table.6User-friendly system interface with all relevant information at a glanceWith its large, innovative touchscreen, the system is designed for intuitive operation, with all information available at a glance in a dashboard format.

加热器通过加热提纯后的废稀硫酸，使其逐渐浓缩；而冷却器则通过冷却剂将浓缩后的废稀硫酸冷却，使其成为可用的稀硫酸。

根据设计要求，制作出合适的浓缩设备。

5. 控制系统的制作控制系统用于监测和控制整个装置的工作状态和参数。

它包括温度控制器、液位控制器、压力控制器等。

通过这些控制器，可以实现对整个装置的自动化控制和运行监测。

6. 装置的组装与调试将主体部分、蒸馏部分、浓缩部分和控制系统等组件组装在一起，并进行调试和测试，确保装置能够正常工作。

总结：以上是一种石英玻璃废稀硫酸浓缩蒸馏提纯装置的制作方法。

通过适当的设计与制作，可以制造出高效、稳定的装置，并实现石英玻璃工艺废稀硫酸的资源化利用，提供了一种解决废水处理和资源回收的技术和方法。
