Once a lead compound is identified, the next phase is process development. This step involves optimizing the synthesis process to produce the API efficiently and safely. Chemists collaborate to determine the most effective reaction pathways, select appropriate reagents, and establish reaction conditions (temperature, pressure, solvent choice), ensuring that the process is scalable for production. Analytical techniques are employed to monitor the reaction and assess the purity of the compounds generated.
Another critical aspect of wastewater treatment involves the removal of dissolved organic matter and nutrients, particularly nitrogen and phosphorus. Chemicals like chlorine and ozone serve as disinfectants, playing a vital role in eliminating pathogenic microorganisms from treated wastewater. While chlorine is commonly used due to its effectiveness and relatively low cost, it can produce harmful by-products, prompting the exploration of alternative disinfectants like ozone, which decomposes into oxygen and leaves no toxic residue.

- Regarding the placement of the cage, the top of the cage should not be higher than your standing eye level. This is because tall parrots are usually superior and not easy to tame. But for overly frightened parrots it can be slightly above your eye level. The bottom of the cage is usually equipped with a tray to prevent objects such as bird seed from falling to the ground and to prevent parrots from bumping their feet through the bars at night. The chassis should be covered with newspaper and replaced daily. To help the parrot feel safer, the cage should have a solid side and not be surrounded by bars. If a solid side is hard to find, put one side of the cage against a solid wall. We have to carefully choose a good cage for the parrot, so that it has a comfortable home.
