Wastewater chlorination treatment
At SITRA we offer wastewater chlorination to help companies comply with regulations, eliminate pathogens and reduce costs with efficient and safe treatment.
How our wastewater chlorination treatment can help you
- Eliminate bacteria, viruses, and other pathogens.
- Prevent the proliferation of algae and biofilms.
- Reduce the presence of unpleasant odors and flavors.
- Ensure compliance with environmental regulations.
Without precise chlorine control, your company risks penalties, odors, and additional costs.
Incorrect dosing not only compromises water quality but also generates unpleasant odors, promotes the proliferation of algae and biofilms, and can lead to costly regulatory non-compliance. Our chlorination treatment eliminates these risks while optimizing performance and significantly reducing operating costs.

How does our chlorinated water treatment for industries work?
- water analysisWe conducted a preliminary study to determine the appropriate dose of chlorine.
- We applied the chlorineWe inject chlorine in a controlled manner into the wastewater flow.
- We disinfectWe let the chlorine eliminate microorganisms and other contaminants from the water.
- We control and adjustWe conduct continuous monitoring to ensure effective and safe chlorination.

Technical specifications of our water chlorination treatment
At SITRA, we implement wastewater chlorination systems with technical features designed to maximize the efficiency and safety of the process.
Chlorine dosage
We adjust the dosage based on water quality and chlorine demand, ensuring a free chlorine residual of 0,5 mg/L for continuous disinfection.
contact time
We guarantee a minimum contact time of 20 minutes to ensure the complete elimination of microorganisms.
Parameter control
We maintain the pH between 6,5 and 7,5 to maximize the effectiveness of the chlorine and adjust the temperature to optimize the process.
Dosing and monitoring systems
We use automatic systems that adjust the chlorine dose and monitor parameters such as residual chlorine, pH, and temperature in real time.
Security and environment
We minimize the formation of by-products and, if necessary, we apply dechlorination processes to protect the environment.
Effective disinfection is not a matter of luck, but of constant technical control
We have implemented chlorination systems in demanding sectors such as agri-food, chemical, pharmaceutical, and municipal wastewater treatment plants. This experience allows us to adapt each solution to the type of effluent, guaranteeing safe disinfection that meets the strictest regulatory requirements.

Frequently asked questions about wastewater chlorination
What is chlorination in wastewater treatment?
Chlorination is a chemical disinfection process that uses chlorine compounds to eliminate pathogenic microorganisms from water. Chlorine works by destroying bacteria, viruses, and other contaminants, leaving a disinfectant residue that prevents recontamination.
It is one of the most widely used methods due to its effectiveness, low cost, and ease of control.
Why is chlorinated water treatment important for my company?
Chlorine treatment ensures that the water discharged or reused is free of pathogens. This is essential to meet the microbiological limits required by discharge or reuse regulations.
Furthermore, it prevents problems with odors, biofilms and algae growth in pipes and tanks, reducing maintenance costs.
What advantages does water chlorination offer compared to other disinfection methods?
Chlorination stands out for several reasons:
- Residual effect: chlorine remains active in the water, protecting against recontamination.
- Competitive cost: it is more economical than ozone or UV radiation
- Ease of dosing: automatic systems allow for precise control
- Broad spectrum: eliminates bacteria, viruses and some protozoa
Its main limitation is the formation of byproducts (trihalomethanes), which we control by adjusting the dose and pH.
What type of chlorine is used in wastewater treatment?
The most common compounds are:
- Sodium hypochlorite (bleach): the most widely used due to its ease of handling and dosage
- Chlorine dioxide: greater effectiveness at high pH and less formation of byproducts
- Chlorine gas: very efficient, but requires strict safety measures
- Calcium hypochlorite: in solid form, useful for installations without a bleach supply
The choice of product depends on the flow rate to be treated, the installation conditions, and the safety requirements.
What maintenance does a wastewater chlorination system require?
Maintenance includes:
- Dosing pump inspection: checking flow rate and diaphragm condition
- Probe calibration: residual chlorine and pH control
- Cleaning of tanks: preventing scale buildup and product degradation
- Alarm verification: ensuring the correct functioning of the control system
We offer preventive maintenance contracts that guarantee continuous operation and optimal system performance.
