Level indicating transmitter for swimming pool level control

A Surge Tank is used at the Okatokes Rec Centre Swimming Pool to regulate pool level. By monitoring level in a surge tank the non-contacting Greyline LIT25 Level Indicating Transmitter controls makeup water flow through a solenoid valve.

Measurement and control systems for the Indicating the level - mechanically

Depending on the regulations, a steam boiler must be equipped with one or more direct and/ or indirect level gauges. With direct level gauges, the liquid level can be seen directly through a glass or mica window. The use of a transparent level gauge with background illumination gives operating staff a clear separation between the water and steam zones even when viewed at a relatively long distance. Bicolour level gauges (black and white or green and red) are very suitable for camera transmission to the measuring...

Boiler Water Testing / Cooling Tower Water Testing

Boilers and cooling towers share two major water related problems: deposits and corrosion. As steam is generated by a boiler or water evaporating from a cooling tower, dissolved minerals are left behind, increasing the concentration of these minerals. Additional minerals are introduced via the water added to makeup the water lost to steam/evaporation. Eventually, the minerals reach a level (or cycle) of concentration that will cause either loss of efficiency due to scale or damage from corrosion. This level...

Determination of zinc in water by fluorimetric method

In accordance with WHO’s Guidelines for Drinking Water Quality there is no health-based guideline value of zinc in water concentration. Concentration of zinc in tap water can increase as a result of its dissolution from pipes. Also, elevated levels of zinc may be an indicator of increased concentrations of other toxic metals; thereby zinc in water analysis is an essential analytical task. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of zinc in...

Online monitoring solutions for the drinking water industries

AppliTek manufactures wet-chemical analyzers specifically designed for measuring on a continuous base the quality indices of drinking water, from raw water intake up to distribution level. Our systems have a small footprint, reduced reagent consumption and show excellent levels of detection in compliance with modern standards. On top of that, the delivery of safe water throughout the water cycle will raise the need for efficient monitoring systems detecting in real-time contaminations. `Broadband toxicity`, a...

COD Reduction

Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water. In wastewater treatment, it indicates the efficacy of a treatment process and is expressed in milligrams per litre (mg/L) or parts per million (ppm). Removing certain fractions of COD in waste streams can be particularly challenging, especially to levels safe for discharge to the environment.

Water monitoring technology for nutrient monitoring

Continuous monitoring of nutrient levels provides crucial information about daily, seasonal and event based changes in water quality conditions, and can be a strong indicator on the overall health of the water body. In recent years, monitoring of nutrients has grown in importance as it has come to the forefront in regulatory compliance of water quality in many regions.

Microbial testing for biological wastewater treatment industry

Realize a new level of process stability and efficiency! Wastewater operators have traditionally had no choice but to rely on TSS or VSS measurements to quantify biomass in their process. These measurements detect much more than just living biomass and therefore are inaccurate and unresponsive indicators of the living population.

Real-time In-situ Effluent Monitoring

The UviLux BOD Indicator enables in-situ, real-time, reporting of BOD within both natural water systems and water processing plants. The monitor detects fluorescent proteins that are inherent within sewage and slurry and provides an output in BOD equivalent units. The principle behind the measurement is the excitation of Tryptophan-like fluorescence within UV wavelength band, which has been shown to correlate with both BOD and bacterial contamination. With complete flexibility of deployment methodology, the...
