Why Disinfection Required for Drinking Water?

 Disinfection of drinking water is required to protect public health by removing or killing harmful microorganisms that may be present in the water. These microorganisms can cause waterborne diseases such as cholera, typhoid fever, dysentery, and hepatitis A.

Waterborne diseases can be spread through contaminated water sources, such as rivers, lakes, and groundwater wells. Disinfection is necessary to ensure that these diseases do not spread through the drinking water supply.

While many water treatment processes remove or reduce the amount of contaminants in drinking water, disinfection is the most effective method of removing or killing the microorganisms that can cause waterborne diseases. By disinfecting drinking water, we can help prevent the spread of waterborne illnesses and protect public health.

Disinfection of drinking water refers to the process of removing or killing harmful microorganisms such as bacteria, viruses, and parasites that can cause waterborne diseases. The aim of disinfection is to make sure that the water is safe to drink and free from disease-causing pathogens.

Disinfection can be achieved through various methods, including:

  1. Chlorination: Adding chlorine to the water to kill microorganisms. Chlorine is one of the most commonly used disinfectants for drinking water.

  2. UV disinfection: Exposing the water to ultraviolet light to kill microorganisms.

  3. Ozonation: Adding ozone to the water to kill microorganisms.

  4. Filtration: Using physical filters to remove microorganisms from the water.

  5. Boiling: Boiling the water can also kill microorganisms.



The specific method of disinfection used can vary depending on factors such as the source of the water, the level of contamination, and the resources available

Reasons why sludge is not settling properly in a clarifier!

 Why sludge not settling in clarifier? There could be several reasons why sludge is not settling properly in a clarifier. Here are some possible explanations: High hydraulic or organic loading: If the clarifier is receiving a high volume of wastewater or if the wastewater has a high concentration of organic matter, it can overwhelm the settling capacity of the clarifier. The excessive flow or high organic load can disrupt the settling process and prevent the sludge from settling effectively. Hydraulic or design issues: Improper hydraulic design or inadequate equipment sizing can lead to short-circuiting or dead zones within the clarifier. Short-circuiting occurs when the flow patterns allow particles to bypass the settling zone, while dead zones are areas where there is minimal or no flow. Both conditions can hinder the settling of sludge. High influent solids concentration: If the influent wastewater has a high concentration of suspended solids, it can result in a dense sludge blanket

Drinking Water Parameters in India !

Image
  As per the Indian Standard for Drinking Water (IS 10500:2012), the following are the recommended parameters for safe and healthy drinking water in India: Microbial Parameters: Total coliform bacteria: No detectable coliforms per 100 mL Escherichia coli (E. coli): No detectable E. coli per 100 mL Faecal Streptococci: No detectable faecal streptococci per 100 mL Chemical Parameters: pH: 6.5 to 8.5 Total Dissolved Solids (TDS): Less than 500 milligrams per liter (mg/L Chloride: Less than 250 mg/L Nitrate: Less than 45 mg/L Fluoride: 0.6 to 1.5 mg/L Arsenic: Less than 0.01 mg/L Lead: Less than 0.01 mg/L 3.Physical Parameters: Turbidity: Less than 5 Nephelometric Turbidity Units (NTU) Color: No standard limit, but colorless or slightly colored water is preferable Odor: No standard limit, but no objectionable odor is preferable. It's worth noting that these parameters may vary depending on local or regional regulations and guidelines, and that water treatment facilities may have additi

Difference between MBR and SBR

Image
Difference between MBR and SBR   MBR (Membrane Bioreactor) and SBR (Sequencing Batch Reactor) are two different wastewater treatment technologies that are commonly used for treating and purifying wastewater. While both technologies employ biological processes for treatment, there are some key differences between MBR and SBR: Configuration: MBR: In an MBR system, the biological treatment and membrane filtration occur simultaneously. The membranes act as a physical barrier to separate the treated water from the biomass and solids. SBR: In an SBR system, the biological treatment occurs in a batch mode, meaning the treatment process occurs in a series of sequential steps. Each step includes a fill phase, react phase, settle phase, and decant phase. Filtration Method: MBR: MBRs utilize membrane filtration as the primary method for solid-liquid separation. The membrane modules contain fine pores that allow treated water to pass through while retaining suspended solids, bacteria, and other co
