Effluent Treatment Plant (ETE)

A wastewater treatment plant (WWTP) is a set of physical, chemical and biological processes used to remove contaminants and pollutants from wastewater before it is released into the environment. The aim is to make the water clean and safe for further use or to return it to the environment harmlessly. ETEs are commonly used to treat effluents from industries, communities and sewer systems.

EP is an effluent treatment company that plays a fundamental role in preserving the environment and finding solutions for the management of your business. It has been working with great dedication and multiplying results for over 50 years.

Operating Process of an Effluent Treatment Plant (ETP):

There are many different processes that can be used in a wastewater treatment plant, but common basic processes include:

Coagulation and flocculation

Addition of chemicals to agglutinate suspended particles in the effluent, forming flocs that can be easily removed.

Decantation

Removal of the flocs formed by sedimentation.

Filtration

Removal of particles not eliminated in decantation.

Biological treatment

Using microorganisms to break down organic pollutants.

Disinfection

Treatment with chlorine or other disinfectants to eliminate remaining microorganisms.

Final disposal

Disposal of treated effluent into bodies of water or its reuse.

The specific processes vary according to the type of effluent to be treated and the treatment objectives.

Benefits

environmental protection

Removal of pollutants before discharge into water bodies.

Water resources

Increases water quality, allowing it to be reused.

Public health

Reduces groundwater contamination and prevents disease.

Quality of life

Improves air quality and reduces bad odors.

Power generation

Some processes, such as anaerobic digestion, generate energy.

cost reduction

It allows water to be reused, saving resources.

Applications

Industry: Used in chemical, pharmaceutical and food industries, among others.
Agriculture: Treats effluents from farms and livestock.
Municipalities: Treats sewage and rainwater from cities.
Mining: Treats effluents from mining activities.
Ports and airports: Treats effluents from these infrastructures.
Ships: Used to treat effluents on board.

Available technologies:

Ultrafiltration:
- It uses fine membranes to remove particles, bacteria and viruses, guaranteeing high water purity.
Physical-chemical:
- Coagulation/Flocculation: Aggregates fine particles to facilitate removal.
- Decantation: Removal of larger flocs by sedimentation.
- Flotation: Uses dissolved air to separate contaminants (see Dissolved Air Flotation System).
Biological processes:
- Activated sludge: Aerobic treatment of effluents.
- Batch process (SBR): Batch treatment system.
- Compact: Compact and efficient systems for limited spaces.
- MBR (membrane bioreactor): Combines biological treatment and membrane filtration.
- MBBR (moving bed biofilm reactor): Uses moving bed biofilm for efficient treatment.
- UASB (upflow anaerobic sludge blanket): Anaerobic wastewater treatment.
- Aeration systems: Different aeration methods to optimize biological treatment.
Advanced Oxidation:
- FENTON process: Uses reagents for advanced oxidation of contaminants.
- Ozone: Powerful oxidizer for removing pollutants.
- UV lamps: Efficient disinfection using ultraviolet light.
- Steelclean process: Specialized solution for the steel industry.
