The DOC and UVA determinations are used in the calculation of the Specific UV Absorbance (SUVA). For TOC and DOC analysis, the sample is acidified and the inorganic carbon (IC) is removed prior to analysis for organic carbon (OC) content using a TOC instrument system. The measurements of TOC and DOC are based on calibration with potassium hydrogen phthalate (KHP) standards. This method is not intended for use in the analysis of treated or untreated industrial wastewater discharges as those wastewater samples may damage or contaminate the instrument system(s). 1.2 The three (3) day, pooled organic carbon detection limit (OCDL) is based on the detection limit (DL) calculation.1 It is a statistical determination of precision, and may be below the level of quantitation.

  • Ultrapure Water
    Ultrapure Water General Filter Requirements Achieving and maintaining ultrapure water (UPW) is extremely important in light of its widespread presence throughout the manufacture of semiconductor integrated circuits. The technology of the industry has advanced so rapidly over the past few years that it has redefined cleanliness requirements, specifically with regard to the need for quantitatively removing colloidal silica, particles, total organic carbon (TOC), bacteria, pyrogens (bacterial fragments) and metal ions. A well-designed UPW system with strategically placed filters, will ensure achievement of this goal, since the type of filter selected in each of the key areas will make a measurable difference in ultimate quality. To meet the demands of a high-purity deionized (DI) water system, filters must: • Not contribute organic, particulate or metal ion contamination to the effluent stream • Not unload trapped contaminants or shed filter material • Be integrity testable to verify removal ratings • Perform identically from lot to lot • Have a low-pressure drop for long life and maximum economy. DI Water Filter A well-maintained UPW system will have a number of carefully selected filters and purifiers placed in strategic positions. A schematic of a DI water system is depicted below. The locations of the filters are representative of those found in a typical water system. Reverse Osmosis (RO) Pretreatment Microza* UNA System Pretreatment is required to operate RO units effectively and economically. The pretreatment will vary depending on the source of the incoming feed water. With surface water as the feed, conventional pretreatment may include such unit operations as coagulation, flocculation, settling, granular media filtration, and cartridge filtration.

Received: 9 April 2014; in revised form: 10 June 2014 / Accepted: 19 June 2014 / Published: 24 June 2014 Abstract: It was discovered at the beginning of this Century that living bacteria—and specifically the extremophile Pseudomonas syzgii—could be captured inside growing crystals of pure water-corroding semiconductors—specifically germanium—and thereby initiated pursuit of truly functional “biochip-based” biosensors. This observation was first made at the inside ultraviolet-illuminated walls of ultrapure water-flowing semiconductor fabrication facilities (fabs) and has since been, not as perfectly, replicated in simpler flow cell systems for chip manufacture, described here. Recognizing the potential importance of these adducts as optical switches, for example, or probes of metabolic events, the influences of the fabs and their components on the crystal nucleation and growth phenomena now identified are reviewed and discussed with regard to further research needs. For example, optical beams of current photonic circuits can be more easily modulated by integral embedded cells into electrical signals on semiconductors. Such research responds to a recently published Grand Challenge in ceramic science, designing and synthesizing oxide electronics, surfaces, interfaces and nanoscale structures that can be tuned by biological stimuli, to reveal phenomena not otherwise possible with conventional semiconductor electronics.

  • Ultrapure Water – the Standard for Resistivity Measurements of Ultrapure Water
    Ultrapure Water – The Standard for Resistivity Measurements of Ultrapure Water Anthony C. Bevilacqua, Ph.D.1 Thornton Associates, Inc. 1432 Main Street Waltham, Massachusetts 02154 Phone (781) 890-3399 Phone (800) 642-4418 FAX (781) 890-5507 email [email protected] Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, continuous calibration and verification are key elements in any QC and QA program. In recent years, users have been using standard solutions to calibrate sensors. However, a major complaint is that these solutions are not in the user’s operational range, and thus are not ideal standards. Numerous standard solutions have been proposed, but none possess all of the desirable requirements : ease-of-preparation, resistivity value in the range of operation, impervious to air and other contamination, and verifiable. During the last several years, as a result of our investigations into the relationship between resistivity and temperature for UPW, we have developed a methodology for calibration that meet all of the criteria stated above. We will provide data to support 5 primary conclusions : 1. The relationship between temperature and resistivity for UPW is well known. 2. Resistivity sensors (for use in UPW) can be calibrated in high conductivity ASTM standard solutions under 1 Please see Acknowledgements for complete listing of contributors. 2 Resistivity and conductivity are identical measurements, differing only in the units of expression.

  • Filters in Electronics and Semiconductor Ultrapure Water Systems – an Overview
    Filters in Electronics and Semiconductor Ultrapure Water Systems – An Overview The general practice in semiconductor ultrapure water (UPW) system operation is to seal the entire system from the second reverse osmosis unit downstream and not open it for 2 to 3 years. The reason for this is that it takes a long time for a system to ‘rinse up’ to ultra-purity after it has been opened, and the entire plant must be shut down during that time. Downtime means lost revenue, which can add up quickly in the semiconductor business. The first RO unit in the system shown in Figure 1 is the equivalent of a prefilter in most other systems. The second RO unit only removes trace contaminants remaining after the first RO unit and the membranes are expected to last for 3 years or more with no cleaning or other maintenance required. With the exception of the pre-RO filters, all of the filters are expected to operate at peak efficiency for the entire time a set of membranes is in place. Below are brief descriptions of the filters shown in Figure 1. Following that overview is a list of possible filter media for each application.

  • Ultrapure Water for Boron and Silica Sensitive Laboratory Applications
    The R&D Notebook A publication of the Laboratory Water Division of Millipore RD003 Ultrapure Water for Boron and Silica Sensitive Laboratory Applications Ichiro Kano (1) and Daniel Darbouret (2) (1) Research & Development, Laboratory Water Division, Nihon Millipore Ltd., Tokyo, Japan. (2) Research & Development, Laboratory Water Division, Millipore S.A., Saint-Quentin-en-Yvelines, France. This article is based on a paper presented at the 1999 Pittsburgh Conference, on March 9th 1999, Orlando, U.S.A.. Abstract: Weakly charged elements or elements that are not well dissociated in water, are not removed efficiently by conventional water purification technologies. In the production of high purity water, silica and boron are generally the first ions to breakthrough into purified water when the ion-exchange resin approaches depletion. In this study, the behavior of these two elements is studied through various steps in a water purification chain. An optimized system configuration is proposed that combines reverse osmosis and electrodeionization technologies in the pretreatment phase, and results in the efficient removal of boron and silica. These initial purification steps produce high resistivity water, presenting a low ionic challenge to ultrapure polishing resins. In addition, a specific chelating adsorbent enhances the retention capacity of boron. Typical values achieved for the most important parameters assessed while producing ultrapure water, are described. A water purification system producing ultrapure water suitable for trace analyses
