Does the industry you work in dispose of waste properly? Surely, you have heard of companies that have been punished for discharging industrial effluents into rivers or seas.

In addition to weighing on the organization's image and pocket, this action can harm the water supply of nearby communities and cause the destruction of entire biomes. These consequences are due to the toxic substances that are generated from the daily work of the factories.

But fortunately, there are effective ways to reduce the impacts of this waste on nature and protect the health of the people who live around it, complying with the law without giving up business development. Do you want to understand more about the subject? In this article, you'll see:

What are industrial effluents?

After all, what is considered an industrial effluent? The name may sound very technical, but its meaning is quite simple. According to the Brazilian Standard — NBR 9800/1987, this is the name given to all liquid wastes generated in industrial activities that are polluted by products used in the operation.

For example, water used to wash equipment in a beverage and food plant is considered an industrial effluent. In this process, the clean liquid may retain substances that are toxic or sanitizing products may even be used.

Therefore, this waste cannot be dumped into the sea or rivers without prior treatment. For each type of effluent, there is an ideal way to dispose of this waste.

What are the characteristics of industrial effluents?

You already know what industrial effluents are, but you may have some difficulty identifying which liquids generated in the production stages of your industry need to undergo special treatment.

It's not just chemicals that need to be considered in this assessment. How about knowing other characteristics that classify these wastes? It's also important to note:

• color — very dark effluents, for example, can obstruct sunlight and harm aquatic ecosystems;
• pH — it is by means of this measure that it is possible to know the degree of acidity of an effluent. Waste of this type with very low pH values is more corrosive and can harm not only the environment, but also cause health problems in people;
• biochemical oxygen demand (BOD) — indicates the amount of oxygen needed to oxidize organic matter by bacteria;
• chemical oxygen demand (COD) — the amount of oxygen needed to oxidize organic matter using a chemical agent.

How does liquid effluent treatment work?

One can see that not treating waste water in industry properly can be very harmful to the well-being of people and nature. In addition, this is a legal obligation. To avoid problems with the law, it is important to follow all the guidelines of the National Environmental Council (Conama).

But, after all, how does this care work with liquid effluents? It is necessary to have the assistance of a specialized company that provides this type of service, since it is necessary to follow a series of steps to finally be able to dispose of this responsibly. And Projesan is an example of this!

We offer planned chemical solutions that bring more safety to industrial and municipal water treatment plants (the one that reaches homes), serving Brazil and other Latin American countries.

Overall, there are three steps to caring for industrial effluents:

• identification and concentration of pollutants that need to be eliminated;
• removal of pollution by specific methods;
• water recovery.

Here on Projesan we believe that by improving water quality, we also contribute to the quality of life of people, businesses and the environment.
