What is Potable water?

 Potable water refers to water that is safe for human consumption. It is free from harmful contaminants and pollutants, and it meets the drinking water standards set by regulatory bodies such as the World Health Organization (WHO) and the Environmental Protection Agency (EPA). Potable water can come from a variety of sources, including groundwater, surface water, and treated municipal water supplies. It is typically treated and purified to remove impurities such as bacteria, viruses, chemicals, and other harmful substances that can cause illness or disease. Potable water is essential for human health and is used for a wide range of purposes, including drinking, cooking, and hygiene.



Potable water should have certain characteristics to ensure its safety for human consumption. Some of these characteristics include:

  1. Clarity: Potable water should be clear and free of any visible impurities.

  2. Taste and Odor: Potable water should be free of any unpleasant taste or odor.

  3. pH: Potable water should have a pH value between 6.5 and 8.5.

  4. Total Dissolved Solids (TDS): Potable water should have a TDS level below 500 ppm.

  5. Microbial Contamination: Potable water should be free of harmful bacteria, viruses, and other microorganisms.

  6. Chemical Contamination: Potable water should not contain harmful levels of chemicals such as lead, arsenic, mercury, and other toxic substances.

  7. Turbidity: Potable water should have low turbidity, which refers to the cloudiness or haziness of water caused by suspended particles.

  8. Hardness: Potable water should have moderate hardness levels, which refers to the presence of minerals such as calcium and magnesium.

  9. Alkalinity: Potable water should have moderate alkalinity levels, which refers to the ability of water to neutralize acids.

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

Importance of DO level in Aeration System?

Image
  What is Dissolved Oxygen (DO) ? In an aeration system, DO stands for Dissolved Oxygen. It refers to the concentration of oxygen molecules that are dissolved in a liquid, typically water. The DO level is an important parameter in aeration systems as it indicates the amount of oxygen available in the liquid medium. In the context of an aeration system, the DO level is usually measured in milligrams per liter (mg/L) or parts per million (ppm). The measurement can be obtained using a DO sensor or probe, which utilizes various principles such as polarography, fluorescence, or optical sensing to determine the oxygen concentration in the liquid. The aeration system introduces oxygen into the liquid medium, usually by bubbling air or oxygen-enriched gas. The oxygen molecules from the gas bubbles dissolve into the liquid, increasing the DO level. The dissolved oxygen is then utilized by aerobic organisms, such as bacteria and other microorganisms, for their metabolic processes. Monitoring the

Reasons why sludge is not settling properly in a clarifier!

Image
 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
