Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.
Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many...
Accurate fountain (dampening) solution concentration control is essential for consistent, high-quality results in lithography. Low concentration can cause drying on the non-image area of the plate resulting in tinting, scumming, blanket piling, etc. High concentrations, on the other hand, bring about over-emulsification of the ink. This results in weakening of color strength and changes in ink rheology (body and flow properties). Correct concentration will allow the non-image areas of the plate to be appropriately...
The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before...
Determination of the pH value provides information about the acid or base action of the soil solution. This in turn is enormously important for the nutrient supply and microbial activity of the soil. For example, many metals (trace elements) are considerably more mobile in acidic soils. If the soil pH values are very low, toxic levels can soon be reached and these can damage the roots of plants. On the other hand, excessively high pH values quickly lead to a shortage of trace elements because of immobilization.

When you need to retrieve high-quality groundwater samples, low flow sampling systems provide an excellent way to retrieve accurate results. While the system is fairly new to the UK, it’s many advantages over more traditional sampling systems has seen its popularity in the industry grow rapidly. Low flow sampling works by extracting the water at rates similar to ambient water flow, which in turn minimises the drawdown of the water level.
Waste water treatment is a multi-stage process to neutralise or disinfect wastewater to within regulatory requirements before it is released into the environment. Considering the wide range of waste water streams and associated difficulties, the control system must be reliable, flexible and with a comprehensive range of functions to be activated for each individual treatment requirement.
Bio-hydrox is more reactive and more effective than ozone and chlorinated chemicals, more stable, with longer residual activity, does not alter the pH, increases the oxygen content and does not create any toxic byproducts. It is ecological and sustainable. Received NSF ANSI 60 approval in 2013, as a drinking water treatment product for the following uses:
Importance of pH Measurement - Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate
measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need to be controlled as precisely as ±0.05 for some processes. Even where this level of precision is needed, process environments are...
Public health authorities in some countries regulate the quality of water in public pools and control water treatment tightly. A typical installation comprises several instruments with a common web-server for access via intranet or internet.

Need to eliminate iron bacteria? Need to remove Hydrogen Sulfide? Oxidize iron and manganese?. Bio-hydrox is a non-toxic Chlorine alternative advanced oxidation product certified NSF/ANSI 60 and available in the USA market since 2013. It is sometimes called “liquid ozone” because it acts similar to ozone when reacts with water.
