Check Osmosis

Check Osmosis

A lot of people have household water treatment equipments such as water softeners (descalers) and reverse osmosis water filter systems.

However, it is advisable to know how these water treatment equipments work; especially concerning filters and cartridges since they can accumulate dirt and may become a source of contamination and, as a result, instead of enhancing the quality of water, it will be reduced; which may pose a health risk to you and your family.

Our water analysis, CHECK OSMOSIS, establishes the physicochemical parameters that allow us to know if our water treatment equipment is working properly or not.

What parameters are included in the analysis?

NH

Ammonium info

Ammonium is a key indicator of water contamination.

The presence of ammonium or ammonia in water is usually associated to organic pollution (wastes composed of animal, human, plant material, fertilizers, etc.) so it serves as an indicator of water pollution.
The presence of ammonia does not often pose a risk to health but it may be related to other problems such as bacterial contamination, the presence of other contaminants, the reduction of chloridation resistance and smell and taste disorders.
The maximum acceptable concentration of ammonia in drinking water for human consumption is 0.5 mg/l.

Cl

Chlorides info

Chlorides reveal the presence of salts in water.

Chlorides in water are broadly related to saltwater intrusion problems, especially in most coastal areas. We get most of our supplies of chloride from the food we eat, mainly in the form of sodium chloride (salt); whereas chloride intake in drinking water tends to be less.
High chloride levels (> 250 mg/l) may impart a salty taste to water. Chloride concentration can lead to corrosion hazards.
Regulations recommend a maximum chloride concentration of 250 mg/l in drinking water.

C

Conductivity at 20ºC info

Conductivity is used to measure water salinity.

Conductivity indicates the level of dissolved salts by measuring the ability of a solution to carry an electric current, i.e. the larger the number of dissolved salts (chloride, sulphate, bicarbonate, etc), the more conductive water is; therefore, by measuring the conductivity of water, we obtain the degree of water salinity.
Variation in conductivity can result through changes in geology of an area. The natural conductivity of water varies from very low values (50 uS/cm), especially in granite (non- calcareous) areas (North of Spain) to very high values (1000 uS/cm), especially in calcareous areas (East of Spain).
The maximum conductivity level in drinking water recommended is 2000 uS/cm.

D

Hardness info

Water hardness is caused by the presence of dissolved minerals.

Hard water is high in dissolved minerals, both calcium and magnesium. Hard water can lead to taste problems and higher consumption of soap to produce lather.
Water hardness should be a concern since hardness greater than 20º F (200 mg/l CaCO3) may cause incrustations in water heaters, boilers, washing machines, irons, etc.
Water hardness lower than 10º F (100 mg/l CaCO3) may a have a low pH buffering capacity and, therefore, cause corrosion in pipes and materials in contact with water.

NO

Nitrates info

Associated with agricultural and livestock activities.

Nitrate compounds are found naturally on earth. Most crop plants require large quantities of nitrates to sustain high yields. The source of excess nitrates in water can usually be traced to agricultural practices, livestock activities and dumping sewage water. High nitrate levels in water can cause methemoglobinemia or blue baby syndrome, a condition found especially in infants under six months.
The maximum allowable limit for nitrate concentration in drinking water is 50 mg/l.

N

Nitrites info

Nitrites can be a significant indicator to determine contamination.

The presence of nitrites in water is largely due to a lack of oxygenated water or water contaminated by sewage water or vegetable waste. Nitrites can also appear when chloramination is used for drinking water disinfection.
The maximum acceptable nitrite concentration in drinking water distribution systems is 0.5 mg/l.

PH

pH info

pH is a measure of how acidic, basic or neutral water is.

pH is a measurement of the acidity or basic quality of water. The pH scale ranges from 0 to 14; a pH of 7 is neutral, a pH less than 7 is acidic and a pH greater than 7 is basic. The pH of natural water hovers between 6.5 and 8.5.
Although pH is not a primary concern for consumers, it is an important water quality parameter. It is associated with the effectiveness of disinfection processes and it can serve as an indicator that contamination may have occurred or that water treatment equipments have been damaged.
pH values in drinking water range from 6.5 to 9.5. The recommended range for pH in swimming-pool water is 7.5; if pH is below 6.0 or above 9.0, it will negatively affect swimmer comfort and pH level should be restored to the optimum range.

Na

Sodium info

Sodium is largely related to water salinity.

Sodium occurs naturally and it related to other salts such as chlorides, sulphates, fluorides, etc. Water softeners (descalers) may increase sodium content of the water for human consumption.
Elevated levels of sodium may result in salty water taste and may cause high blood pressure.
The maximum acceptable level of sodium in drinking water is 200 mg/l.
Natural water can be classified by the amount of sodium per liter:
- Sodium water: more than 200 mg/l
- Water for children-food preparation and low-sodium diet: up to 20 mg/l.
