In addition to coagulation, solid chemicals are integral in the disinfection phase of water treatment. Chemicals such as chlorine, chloramine, and chlorine dioxide, although mostly in liquid form, can also be stored and used in solid or tablet forms for convenience and safety. These disinfectants effectively eliminate harmful microorganisms, viruses, and bacteria, ensuring treated water is safe for human consumption and use. The effectiveness of these solid disinfectants is crucial, especially in areas lacking advanced water treatment infrastructures.

Pyrroloquinoline quinone (PQQ) is a novel compound that has garnered attention for its potential health benefits, particularly in the realm of cellular energy production and oxidative stress mitigation. With the global emergence of COVID-19, a disease triggered by the SARS-CoV-2 virus, researchers and health professionals have been exploring various avenues to bolster immune function and enhance recovery in infected individuals. This article delves into the potential influence of PQQ in the context of COVID-19.
Disinfection is a critical step in sewage treatment to eliminate pathogens before the treated water is released or reused. Common disinfectants include chlorine, ozone, and ultraviolet (UV) light. Chlorine is widely used due to its effectiveness and cost-efficiency, although it can form harmful byproducts. Ozone is another powerful disinfectant that breaks down organic pollutants without leaving harmful residues. UV treatment, while chemical-free, requires substantial energy and infrastructure but is increasingly popular for its safety and efficacy.
