  Hard water contains a high level of calcium and magnesium. These minerals can be toxic if not filtered out properly. On the other hand, soft water has a lower concentration of ions and easily lathers with soap.      We will learn further about hard water and soft water down below. What is Hard Water? Hard water is household water that contains a high concentration of minerals such as calcium and magnesium. These minerals are not toxic but they can still be harmful to the human body at high levels. Effects of Hard Water High levels of minerals have effects from minor irritation to highly destructive properties. Hard water causes cloudy water spots in sinks, dishes, silverware, and bathtubs. It also causes white, crusty deposits on tea kettles and coffee pots. Bathing and showering in hard water can make your skin feel dry and itchy. Since shampoo does not lather up very well in hard water, it leaves your hair looking limp and dry. What is Soft Water...

When it comes down to treating chronic skin diseases such as eczema, softened water can make all the difference. Recent research proves that hard water has negative effects on the skin. Scientists at the University of Sheffield and King's College London proved that hard water damages the skin, raises the risk of infection and contributes to the development of Eczema. What is Eczema? Eczema or Atopic Eczema is the name of a chronic skin disease which causes irritation and flaky skin. This skin condition causes itchiness and patchiness of dry skin across the body. Eczema damages the skin barrier function which is the glue of your skin. The uppermost layer of the skin is the skin barrier function that protects from excessive transepidermal water loss (TWEL). This destruction of barrier function makes your skin more sensitive and prone to infection and dryness. Causes of Eczema The most common reasons for Eczema are poor diet, negligible shower habits, contact with household ...

To meet the government regulations and standards set by the industry, numerous wastewater solutions have been introduced. Depending on the application of the treatment, one or more chemicals may be necessary for the treatment within the regulations. The different types of chemicals: Coagulants Coagulants are alumunium or iron-based chemicals that change the magnetic charge of particles in water. These magnetic charges attract instead of repelling each other. The waste debris then forms into larger debris which can be filtered out later. The debris removed from the wastewater usually includes arsenic, pathogens, organic matters, fluoride, and chemical phosphorus.   Flocculants Flocculants are divided into three types: natural, chemical and grafted. Usually used in water agitation processes, flocculants help waste particles to form clumps or large debris through charge bridging, electrostatic patching and magnetic neutralization. Defoamers As the name imp...

  The treatment of wastewater is one of the most crucial steps in industries and factories. If left untreated, the wastewater can destroy the environment and affect the people and animals that live in it. There are several methods to treat wastewater and chemicals are one of them where the debris and waste particles are separated from the  Wastewater Treatment Plants India . The following are the few uses of chemicals in wastewater treatment plants: Removing the Solid Particles Removing solid particles from wastewater isn't easy, so chemicals such as ferric chloride, polymers and alums are used to produce positive charges. These positive charges neutralize the negatively charged particles. As a result, the solid particles are all clumped together, which makes it physically easier to remove the material. pH Neutralization In wastewater treatment, an acid or base is added. Depending on the pH level of the water being treated, either sulfuric acid or a base ch...

  Waste is always inevitable to avoid in the process of Industries and Manufacturing. The chemicals used in treatment are no exception, since wastewater treatment is a process of removing dirt and waste. Chemicals offer a soluble solution to industrial waste which is more environment-friendly. Listed below are chemicals that have valuable application to the wastewater treatment:   Aluminium Sulfate   One of the most common chemicals used in wastewater treatment plants is aluminium sulfate. Aluminium Sulfate acts as a purifier in the wastewater plant for the wastewater. Aluminium Sulfate is soluble and easily reacts to the chemicals in the wastewater. As a result, it break downs insoluble and hazardous chemicals.   It also aids in regulating the pH level of chemicals, making wastewater less dangerous to the environment. Despite the many benefits of aluminium sulfate, excessive use of the chemical can also backfire. If the levels of aluminium sulfate are...

The wastewater treatmentplants in India have effectively controlled conventional pollutants like bacteria, COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), suspended solids, etc. Wastewater treatment plants face newer challenges with “emerging pollutants.” These include pesticides, pharmaceuticals, personal care products, and fertilizers. As of now, there are no specific treatment processes or standard testing methods for the emerging pollutants. Trace quantities of agents or certain indicator constituents of these pollutants have been found in treated wastewater.   Alternates to chemical treatment in wastewater treatment plants.   Another alternative and popular method to chemical treatment is biological treatment in wastewater treatment. Biological treatment is when the microorganism present in the wastewater reduces the organic matter aerobically and anaerobically. The microorganism requires food which is BOD (Biochemical Oxygen Demand) that it consum...
