Alkalinity

Alkalinity is a measure for the buffer capacity of natural waters. It gives the amount of acid that needs to be added to cause a color change of the indicator methylorange (m‑value, pH 4.3) or phenolphthalein (p‑value, pH 8.2). Alkalinity is mainly caused by a combination of carbonate, bicarbonate, and hydroxide ions. If the alkalinity is high, the addition of acids or bases has only a little influence on the pH.
Alkalinity inhibits corrosion in boiler and cooling water. Additionally, alkalinity is an important parameter for quality control in process water, aquariums, and swimming pools.

Aluminum

Water-treatment plants use aluminum potassium sulfate (Alum) in order to flocculate suspended solids. The level of aluminum in finally treated drinking water may increase because of this process and therefore has to be tested. Depending on national regulations, different aluminum concentrations are tolerated in industrial effluents. In natural waters, the concentration of aluminum compounds is usually low.

Chlorine

Chlorine is widely used for disinfection of swimming pools, water mains, and water reservoirs. Electroplaters use chlorine for the detoxification of cyanide‑containing waste. Regular monitoring of chlorine level is essential as excessive chlorine not only impairs the smell and taste of water but also can be hazardous. One distinguishes between free chlorine and combined chlorine (chloroamines); the sum of both is called total chlorine. Learn More about Chlorine

Cyanide

Cyanide is extremely toxic. The lethal dose is about 1 mg/kg body weight. A careful control is therefore essential, whenever cyanides are used for industrial processes, e.g. in electroplating or in the extraction of gold. Intense control is also required in the production of fruit brandy from stone fruit.

Humidity, Relative

Products that are sensitive to moisture must be kept dry. To achieve this, such products are often packed in PE bags with a desiccant. Moisture indicators allow a simple, visual control whether the product is still kept dry. Conventional moisture indicators are based on cobalt chloride, which is classified as toxic and carcinogenic. The cobalt chloride-free moisture indicators do not contain toxic or carcinogenic substances.

Nitrate

Nitrate is a by‑product of biological decay from plant and animal matter (nitrification). Nitrate is reduced to nitrite easily, which can lead to diseases and increased fish mortality. Furthermore, high concentrations of nitrate itself are also harmful. Such concentrations are found predominantly in agricultural areas where nitrogen fertilizer is regularly used.

Nitrite

Nitrite is produced as an intermediate in the nitrification in sewage treatment plants. An excessive content of nitrite indicates that the plant’s biology does not work optimally. A high level of nitrite in cooling lubricants indicates a microbiological contamination of the circuit (see also cooling lubricants). Nitrite has to be controlled in aquariums as well in order to ensure optimum living conditions for the aquatic life. Learn More about Nitrite

Peroxide

Hydrogen peroxide is a disinfectant. It is used in the dairy and beverage industry for disinfection of packaging. Prior to the disinfection, the check for a sufficiently high concentration of peroxide is mandatory. After the disinfection, the complete removal of peroxides has to be controlled.
Some solvents, which are used in the chemical industry, tend to form peroxides. The check for peroxides in such solvents is of importance to avoid explosions during heating.

Phosphate

High levels of phosphate in surface water are an indication of domestic sewage, fertilizer or industrial wastewater. Very high levels lead to eutrophication (over‑fertilization) of rivers and lakes and can ultimately lead to the death of fish and plants. The elimination of phosphorus from wastewater is therefore an important target of cleaning in sewage treatment plants. Learn More about Phosphate

Surfactants (detergents)

Surfactants are surface‑active substances which are widely used in various industries, by soap manufacturers, and also in private households. Generally, one distinguishes between anionic, cationic, and nonionic surfactants. The concentration in municipal waste water can reach high levels, which are caused for example by laundry surfactants.

Water Hardness

Water hardness is primarily caused by calcium and magnesium. It forms deposits in pipes and on heating elements and can lead to damages. Testing water hardness is important to dose water softeners correctly. Very low residual hardness is required in industrial boiler feed water. Learn More about Hardness
