 📌 The water treatment field is full of chemical terms that might seem complex, but they are essential to understanding the processes and analyses that ensure clean and safe water. Here’s a simplified breakdown:

➡️ Chemical Terms 💬 in Processes:

1. Coagulants: Chemicals that cause fine particles in water to clump together for easier removal (e.g., Aluminum sulfate (Al₂(SO₄)₃), Ferric chloride (FeCl₃)).

2. Flocculants: Substances that enhance the clumping of particles into larger masses during treatment (e.g., Polyacrylamides (PAMs), Polyaluminum chloride (PAC).

3. pH Adjusters: Chemicals used to change the acidity or alkalinity of water (Acidic: Sulfuric acid (H₂SO₄), Basic: Sodium hydroxide (NaOH).

4. Disinfectants: Agents that eliminate pathogens in water (e.g., Sodium hypochlorite (NaOCl), Ozone (O₃).

5. Anti-Scalants: Chemicals that prevent scale buildup from minerals in water systems (e.g., Polyphosphates, EDTA).

6. Oxidizing Agents: Chemicals that react with contaminants, altering their chemical structure (e.g., Potassium permanganate (KMnO₄)).

7. Adsorbents: Materials that capture and remove dissolved substances from water (e.g., Activated carbon, Zeolites).

8. Ion-Exchange Resins: Polymers that replace unwanted ions with desirable ones (e.g., Cation resins, Anion resins).

➡️ Chemical Terms 🧪🔬in Analyses:

1. TDS (Total Dissolved Solids): Measures dissolved substances in water, expressed in mg/L or ppm.

2. Turbidity: Indicates water clarity, measured in NTU.

3. BOD (Biochemical Oxygen Demand): The amount of oxygen needed to decompose organic matter in water, measured in mg/L.

4. COD (Chemical Oxygen Demand): Total oxygen required to oxidize matter in water, measured in mg/L.

5. pH: A scale measuring the acidity or alkalinity of water, ranging from 0 to 14.

6. Hardness: Concentration of calcium and magnesium ions, measured in mg/L as CaCO₃.

7. Conductivity: Indicates water's ability to conduct electricity, measured in µS/cm.

8. Chlorine Residual: The amount of chlorine left in water after disinfection, measured in mg/L.

9. Alkalinity: Water’s ability to neutralize acids, expressed in mg/L as CaCO₃.

10. Nitrate (NO₃⁻): A nutrient compound, measured in mg/L.

11. Phosphate (PO₄³⁻): A key nutrient, measured in mg/L.

12. Heavy Metals: Elements like Lead (Pb), Mercury (Hg), and Arsenic (As), measured in µg/L or mg/L.
