Wastewater treatment for a healthier environment

Wastewater treatment is a process that removes pollutants from domestic and industrial use. It consists of a set of chemical, biological and physical methods carried out at large sewage treatment plants.

Wastewater: significant polluting load

Industrial water is any water that comes from a production process. The characteristics of this water depend on the nature of the industry. The wastewater treatment laboratory decides whether this water will flow into the stormwater or sewage system.

Before discharging into the natural environment, wastewater must undergo a series of treatments to meet the established standards and preserve the environment. To do this, they are sent through the collection network to wastewater treatment plants for their processing.

Industrial wastewater treatment It begins with a preliminary analysis of wastewater to determine its characteristics, as well as pollutants. For wastewater treatment at sewage treatment plants, you must perform several steps:

  • Pretreatment: retention of bulky waste
  • Primary treatment: physical or chemical
  • Secondary processing: biological
  • Tertiary treatment: clarification
  • Sludge treatment: disposal, incineration or reuse

The need for treatment in sewage treatment plants

The purpose of wastewater treatment is to provide clean water that does not contain pollution and is compatible with natural water systems. Several treatment processes can be implemented depending on the content of the contamination and the nature of the waste.

The goal of the wastewater treatment process is to purify water for reuse or conversion to drinking water. The wastewater treatment plant, installed downstream of the network, consists of a set of equipment that allows water to be cleaned of various residues and detritus.

In fact, wastewater is overloaded with pathogenic bacteria, toxic chemical elements and suspended substances that enter the natural environment, causing asphyxiation of living beings and the mass destruction of the animal and plant world.

To maintain a constant balance of natural ecosystems, the water entering the treatment plant passes through several pools to eliminate various types of hazardous waste.

At the mouth we get clean water and without any pollution that can be dumped into nature without any danger. Inspection measures are always carried out by the state to verify that the treatment facilities comply with the standards required by law.
