While the human body can synthesize some amount of PQQ, it is also obtained through diet. Foods rich in PQQ include fermented soy products, spinach, green tea, and certain fruits such as kiwi and papaya. However, many individuals may not consume adequate amounts of these foods, leading to interest in PQQ supplementation.
Disinfectants are another critical component of water purification. Their primary role is to eliminate pathogens, including bacteria, viruses, and protozoa, ensuring that the water is safe for human consumption. Chlorine is one of the most widely used disinfectants due to its effectiveness and cost-efficiency. However, alternative disinfectants such as ozone and ultraviolet (UV) light are gaining popularity, especially in applications where chlorine's byproducts may pose health risks.
As agricultural technology advances, the application prospects for new water treatment chemicals in sustainable agriculture are vast. These chemicals not only address current water quality issues in irrigation systems but also complement smart agriculture technologies such as remote sensing, big data analytics, and IoT devices. This integration enables more scientific and automated irrigation decisions, significantly improving agricultural production efficiency and sustainability. By contributing to global food security and environmental protection, water treatment chemicals play a vital role in the future of sustainable agriculture.
One of the major categories of chemicals found in sewage water is organic pollutants, which are primarily derived from household products, pharmaceuticals, and personal care items. These include substances like detergents, soaps, and a variety of active pharmaceutical ingredients (APIs) from prescription and over-the-counter medications. Recent studies have highlighted the presence of antibiotics, hormones, and pain relievers in wastewater, raising concerns about their effects on aquatic life and the potential for antibiotic resistance in microbial populations.
