Getting back to basics: What is pH?

by Environmental Services by Daniel L. Theobald  (Feb. 9, 2014)

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 ...

pH Probe Maintenance

by Digital Analysis Corp.  (Jul. 14, 2010)

The success or failure of pH measurement depends on the proper application of the probe and proper subsequent maintenance of the probe. The procedures described within apply to the most common pH probe in use today and that is the flat surface combination pH probe. The most common failure mode associated with pH probes is breakage. The pH ...

pH Electrode Architecture

by Digital Analysis Corp.  (Jul. 14, 2010)

A pH Electrode can be compared to a battery in that an electrical voltage is generated between two points that is a function of water chemistry. In the case of a pH electrode the voltage potential is a function of the acidity or alkalinity of the solution in which it is immersed. Note: The terms pH electrodes and pH probes are often used ...

Major waste management company and cbio combine resources, to resolve a breach of ammonia consent, in a large wastewater treatment plant case study

by Cleveland Biotech Ltd  (May 29, 2014)

The WWTP itself is located in the East Midlands, and treats dairy waste from a large processing plant, treating c1,500m3 of effluent per day. On 30th July the ammonia (NH3) levels in the permeate from the MBR at the plant began to increase. The effluent plant discharges to a river and as such, the consent limit is stipulated by the Environment ...

pH Adjustment - A Primer

by Digital Analysis Corp.  (Jul. 14, 2010)

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 ...

Monitoring pH and ORP in a SHARON reactor

by IWA Publishing  (Jan. 1, 2011)

This paper analyses the valuable information provided by the on-line measurements of pH and oxidation reduction potential (ORP) in a continuous single high ammonia removal over nitrite (SHARON) reactor. A laboratory-scale SHARON reactor equipped with pH, ORP, electric conductivity and dissolved oxygen (DO) probes has been operated for more than ...

Impact parameters investigation of DNA immobilisation process on DNA sensor response

by Inderscience Publishers  (Apr. 8, 2013)

This paper studies impact parameters of DNA sequence immobilisation on DNA sensor response. The parameters were examined including immobilisation time, carbon nanotubes concentration, DNA probe concentration and pH value. The DNA probe sequences were immobilised on surface of microelectrodes by using multi–walled carbon nanotubes (MWCNTs) as ...

In-pipe monitors turn dreams into reality

by Intellitect Water Ltd  (Aug. 16, 2012)

In-pipe monitors turn dreams into reality The quality of tap water has improved enormously in recent decades, but for largely technological reasons, until recently, knowledge of water quality between the treatment works and the tap has been an almost impossible dream for water treatment and distribution network managers. In this article, Jo ...

Water quality monitoring with hydrolab MS5

by OTT Hydromet  (May 6, 2010)

Background The Škocjan caves are a unique natural phenomenon located in south western Slovenia and are preserved as the Škocjan Caves Park under UNESCO protection. One of the most famous network of underground caves in the world, they were formed by the flow of the Reka River as it bored tunnels through the region’s limestone geology. The river ...
