Water is essential for humanity, but even so, only 1% is available for human consumption. We know how important it is to our homes when treated and fit for consumption. But what about industries? What is its use in industrial processes? What is the importance of water analysis in industries?
Water for industry is used in a series of processes, both for manufacturing the products themselves and for cleaning materials and instruments. Therefore, in this sense, it must be pure and free of microbes or harmful substances. Poor water quality is not always visible, so a laboratory analysis is certainly necessary to detect any abnormality, since many diseases are contracted through water. In short, strict control is essential for people’s health and environmental conservation.
How is the use of water in industries?
Most industrial processes use water. For the manufacture of an item, it is often essential to use water to dissolve a chemical product, extract substances and for washing products and equipment. In papermaking, for example, water is used for bleaching pulp. Also in the textile industry, water is important for washing and dyeing fabrics, and is certainly essential for cooling in mills, requiring a large and continuous amount of water for this process.
When it comes to the food industry, it is necessary to offer an even greater safety, because the factories must have a strict quality control. The lack of such care can have serious consequences for people’s health. Thus, companies should apply preventive measures to avoid any problems in the manufacture of food. For example, carry out a strict evaluation of the production processes, with water quality being one of the essential.
What should be the acceptable water standard in industries?
According to the Ministry of Health, water for human use must be potable and not pose health risks. Thus, the following standards have been formulated:
- Microbiological standard: for the amount of faecal coliforms;
- Harmful chemical composition: regarding the concentration of lead, mercury, nitrates, benzene, pesticides, etc.;
- Regarding radioactivity: if it has high rates of radio-226 or 228;
- Organoleptic standards: referring to color, smell, flavor and others.
These items are identified by a tolerance table of their quantity in water and the data are used as a basis for laboratory analysis.
How can industries have good quality water available?
For this, it is necessary to take some important measures, such as the following:
Know the origin of water
Industries can use water from public systems or use their own. The first one is already treated and potable. In the second case, the companies are responsible for the treatment, and consequently must follow a strict standard, thus having the advantage of having a better control over the origin of the water.
Have your own treatment system
Even coming from the public water supply, water must be taken care of, whether in its storage or treatment, so that it presents a standard of good quality. In this way, it is important that each industry has its own water treatment system.
Monitoring water quality
The control of water treatment in industries is essential. Periodic monitoring with microbiological and chemical analysis is required to ensure safe water use and consumption.
As we have seen, water quality is essential for industries, especially those that manufacture food. And the best way to avoid the contamination of this resource is through the awareness of companies. Thus, the ideal is to have their own system of control, analysis and treatment of water used in their processes.
