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
How to solve partially filled pipe flow measurement challenges
How variable frequency drives can reduce installation and programming costs while providing a host of other benefits

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.
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.
Process Filtration Technology: Making Informed Decisions
Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.
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:
An exploration of an innovative system that enables wastewater capacity expansion
Why chemical makers are increasingly focusing on water-related risks and opportunities

Bristol-Myers Squibb Works hard to be a Good Neighbor
Bristol-Myers Squibb manually monitored dissolved oxygen (DO) periodically and ran aeration blowers more than necessary to guard against variable loading rates. After upgrading the system to use online DO monitoring operators now have continuous DO readings in the aeration tanks, substantially reducing energy and maintenance costs.
Chemical makers increasingly are focusing on water-related issues. In particular, concern over availability is spurring leading operating companies to implement a host of novel strategies and technologies to optimize water use. Chemical makers are implementing strategies and solutions to scale back on their overall usage of water, reuse water and put clean water back in to circulation. In this ChemicalProcessing Water Optimization eHandbook we take a look at how chemical companies are dealing with water challenges

A Treatise of Filter Cake Washing Mechanisms in Pressure and Vacuum Filtration Systems
During many chemical operations, cake washing is required since no filter system can remove all of the mother liquor by pressure or vacuum dewatering only. The topic of how to most efficiently wash the cake is important. This article introduces pragmatism into cake washing theory and will help engineers during their decision-making processes.
What Does It Cost To Own Your Dust Collector Filters?
When choosing filters for your cartridge dust collector, a Total Cost of Ownership (TCO) calculation allows you to make the most economical and sustainable choice. TCO is a step-by-step evaluation that explores energy use, maintenance and other factors to compare the real costs of operating a dust collector with different filters. This white paper explains how to perform TCO calculations to save money, time and energy.
