The most commonly used compound in the chemical industry is water – not only as a solvent in processing, but also as an energy carrier in the cooling or heating cycle. As vast amounts of water are needed, chemical industries are often located close to large bodies of flowing water. Water used as processing or cooling water is cleaned and subsequently led back to the river or stream. For environmental protection, these waters are subject to specific control and monitoring measures. As the total organic carbon (TOC) non-specifically detects all organic compounds, this parameter has proven to be invaluable here. This booklet introduces a variety of industry-specific applications, and how Shimadzu can provide TOC analyzers to meet specific chemical application needs.
Breakdown of organic wastes entering a wastewater treatment plant is accomplished by using a biomass or blend of beneficial microscopic organisms, bacteria, and solids. This converts the nonsettleable solids (dissolved and colloidal matter) into settleable solids, carbon dioxide, water, and energy. This paper reviews the most common stages for measuring and controlling dissolved oxygen in a wastewater treatment plant.
Economic growth, industrialization and population growth are driving the increasing demand for water, while factors such as climate change, pollution and regulation are affecting the supply and costs related to water.” The chemical industry, being highly water intensive, certainly is exposed to water-related risks. Any efforts to manage these risks and capitalize on opportunities begin with the measurement and appreciation of how water may impact business, followed by the development of strategies to protect the business both now and in the future. In this Chemical Processing Special Report we take a look at water challenges and potential solutions for chemical processors including:
Water-related risks and opportunities
How chemical makers strive to cut water consumption and improve treatment
The Importance of visible TOC levels
HACH BioTector 3500c Analyzer For TOC, TC, TIC and VOC Analysis
In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.
Treating and reusing process water is a multidimensional challenge for process plants. Compliance with regulatory requirements to prevent and mitigate industrial pollution can require significant capital investment as well as ongoing maintenance outlays. The increasing scarcity and cost of fresh water for production processes also compounds the problem. In this Chemical Processing Wastewater eHandbook we take a look at how to widen your perspective on wastewater including:
Optimizing water cleanup with activated carbon - including a few pointers to make the most of absorption systems
Improving plant performance with solids/turbidity monitoring - how continuous monitoring in the liquid processes stages of a wastewater treatment plant offers important benefits

Chemical facilities are under mounting pressure to process ever larger quantities of wastewater to increasingly higher standards while staying within a variety of cost constraints. Plant operators face the dilemma of how to maintain treatment throughput at reasonable cost even when the plant reaches design capacity. Potential changes to production mixes can compound the challenge. Fortunately, adopting the latest wastewater-treatment technology can inject new life into a plant, extending useful asset life without heavy upfront capital investment. In this Chemical Processing Wastewater eHandbook we take a look at how to boost wastewater improvement efforts including:

Water is a critical utility at process plants, often serving both as a heating and a cooling medium. Many process plants rely on this water for processing and other applications. Providing the water, usually by heating via steam coils or direct steam injection nozzles, takes significant energy. In this Chemical Processing WasteWater we take a look at water best practices including:
How to cut energy consumption in water systems in both hot and cold water applications
Polymer piping - we identify benefits over metallic systems
TOC analysis challenges - techniques that address barriers to standard online TOC measurement methods
