Common lab instruments include microscopes for viewing samples, centrifuges for separating substances, and spectrophotometers for light measurement. Other instruments like pipettes, balances, autoclaves, and incubators are also essential for experiments and analysis.
STP plants process influent (raw sewage), effluent (treated water), and sludge (solid waste). Gases like methane are produced during treatment, which involves various mechanical and biological processes.
Testing kits include pH kits to measure acidity, BOD and COD kits for organic and chemical pollution, and microbiological kits for detecting bacteria. Water quality kits help monitor parameters like turbidity and hardness.
Rigid packaging is solid and retains its shape, often made from glass or metal. Polymer packaging is flexible, lightweight, and cost-effective, commonly used in plastic bags and films for packaging.
