Wastewater Treatment Processes

Civilian wastewater treatment solution systems commence with preliminary treatment. Screening and sedimentation are used to eliminate large solids and debris from the wastewater. Subsequently, biological treatment takes place. Microorganisms in activated sludge processes or trickling filters decompose organic matter. Chemical treatment is also incorporated to adjust pH and remove contaminants like phosphorus and nitrogen.

Solution features:

The combination of screening and sedimentation efficiently removes large impurities, preventing clogging in subsequent treatment steps. Biological treatment is an environmentally friendly way to break down organic substances, reducing the need for harsh chemicals. Chemical treatment allows for precise control of water quality parameters, ensuring the removal of specific pollutants.

Disinfection and Water Reuse or Discharge

 

After the treatment processes, the wastewater undergoes disinfection. Chlorine or ultraviolet light is typically used to kill remaining pathogens. The treated water can then be safely discharged into the environment, such as into water bodies, or reused for non-potable applications like irrigation or toilet flushing.

Solution features

Disinfection is crucial for protecting public health by eliminating harmful bacteria and viruses. The option for water reuse helps conserve water resources, reducing the demand for fresh water. Safe discharge into the environment minimizes the negative impact on ecosystems and complies with environmental regulations.

Everything you should know about Civilian Wastewater treatment Solution systems

The frequency of cleaning the screening filters depends on the amount of solids and debris in the incoming wastewater. In general, for a typical household wastewater treatment system, it might need to be cleaned once a week or bi-weekly. However, in areas with higher levels of solid waste, such as near construction sites or during heavy leaf-fall seasons, it could require more frequent cleaning, perhaps every few days.

Yes, the biological treatment process can be significantly affected by temperature. Microorganisms in the activated sludge or trickling filters have an optimal temperature range for their activity. For most common bacteria used in wastewater treatment, this range is around 20 – 35°C. If the temperature drops too low, the metabolic activity of the microorganisms slows down, reducing the efficiency of organic matter decomposition. Conversely, if it gets too high, it can lead to the death of some beneficial microorganisms and the overgrowth of harmful ones, disrupting the treatment process.

Ultraviolet (UV) light is a popular alternative to chlorine for disinfection. UV light works by damaging the DNA of pathogens, preventing them from reproducing and causing infections. Ozone is another option. It is a powerful oxidizing agent that can kill a wide range of microorganisms. However, ozone is more expensive and requires specialized equipment for its generation and application. Some systems also use a combination of disinfectants, such as a small amount of chlorine followed by UV light, to enhance the disinfection effect and reduce the formation of harmful disinfection by-products.

The quality of the treated water is monitored through various parameters. Chemical parameters such as pH, levels of ammonia, nitrate, phosphate, and dissolved oxygen are measured regularly. Biological parameters like the presence and quantity of fecal coliform bacteria and other pathogens are also tested. This is usually done using laboratory analysis, where samples of the treated water are collected and analyzed using specific chemical reagents and analytical instruments. Some modern wastewater treatment systems also have online sensors that can continuously monitor certain parameters like pH and dissolved oxygen, providing real-time data and allowing for immediate adjustments if the water quality deviates from the desired standards.
