  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • Chemicals used for pH Adjustment

    The Chemistry of Limestone Treatment: Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO3, the primary constituent of limestone) to form water, carbon dioxide and calcium salts. The following depicts the neutralization ...

  • pH Adjustment - A Primer

    A brief review of the definition of pH, the pH scale, and some of the chemistry involved in pH Adjustment systems is provided below. For some this may be trivial, yet for many others this may be useful. The information provided below is typical of the background information we provide in our training classes / seminars. By Definition pH is the measure of free hydrogen activity in water and can be ...

  • Cycle chemistry pH measurement

    pH measurement in high purity water has met with variable success. The high resistivity of pure water, the vulnerability to contamination, the variability of reference electrodes and additional temperature effects converge to make tins a particularly challenging measurement. Overcoming these obstacles requires a thorough understanding of the potential problems and their systematic solution. ...

  • Measure pH, conductivity, oxygen with HQD

    After just a short time, the HQD digital electrochemical measuring system has already established itself in practice. Both in the laboratory, with standard electrodes, and in the field, with rugged outdoor electrodes.  On the following pages, users describe their experience with the HQD system. Their experiences show that the system covers a wide range of applications, including direct ...


  • HD Q-PAC® Media for Aquarium Water Treatment in Life Support System: pH, Dissolved Oxygen, and Turbidity Improved Significantly

    The Newport Aquarium needed to improve the clarity and quality of sea water in its large fish exhibit. After evaluating alternatives with independent consultant Dave LaBonne, Jeff Gibula (Husbandry Operations Manager) decided to use HD Q-PAC® media in his one of his life support systems. HD Q-PAC® is considered an excellent choice for use in aquarium water treatment, both for newly constructed ...

  • Getting back to basics: What is pH?

    Getting back to basics: What is pH? The most used measure in wastewater treatment, and for good reasons The “potential of hydrogen” or “pH” is the measure of free hydrogen activity in water and thereby indicative of the measure of its free acidity or free alkalinity. Gauged on a numeric scale of 0-14, solutions with a pH of less than 7.0 are acids. ...

  • DOD evaluates bioaugmentation for remediating low-pH aquifers

    The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

  • Elimination of selected pharmaceuticals by biosolids from municipal wastewater treatment plants: importance of modest pH change and degree of mineralization

    Lab-scale batch experiments with biosolids collected from a full-scale activated sludge system (AS) and a pilot-scale membrane bioreactor (MBR) were carried out to investigate the mechanisms of elimination of 5 acidic pharmaceuticals and 2 neutral pharmaceuticals. Batch elimination experiments were conducted under the conditions of pH of 6 and 7, and a great impact of pH on elimination of ...

  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Effects of different substrates in the mitigation of algae-induced high pH wastewaters in a pilot-scale free water surface wetland system

    Waste stabilization ponds (WSPs), as part of municipal wastewater treatment strategies, can exhibit variability in performance due to climatic conditions. Under elevated temperature and strong solar radiation, algal blooms and subsequent high pH effluents have often been observed. In this study, four substrates (gravel, peat, organic mulch, and topsoil) were evaluated for their ability to ...

  • pH control for enhanced reductive bioremediation of chlorinated solvent source zones

    Enhanced reductive dehalogenation is an attractive treatment technology for in situ remediation of chlorinated solvent DNAPL source areas. Reductive dehalogenation is an acid-forming process with hydrochloric acid and also organic acids from fermentation of the electron donors typically building up in the source zone during remediation. This can lead to groundwater acidification thereby ...

  • ORP and pH Based Control of SBR Cycles for Nutrient Removal from Wastewater

    ABSTRACTContinuous monitoring of multiple process functions were conducted involving removals of BOD, TSS and nutrients, in each cycle of the SBR reactor at the wastewater treatment plant of the City of Carrabelle, FL. On line, real time, monitoring of pH, oxidation reduction potential (ORP), dissolved oxygen (DO), ammonia-N, nitrite-N, nitrate-N and orthophosphate-P demonstrated excellent ...

  • The Control of pH and Oxidation Reduction Potential (ORP) in Cooling Tower Applications

    The importance of keeping cooling tower water in proper chemical balance is becoming clearer. Cooling tower treatment control systems can limit scale formation to improve efficiency, limit corrosion to increase the service life of the cooling water system, and maintain a residual halogen level to reduce liability associated with biological growth, particularly Legionellae.   The use of ...
