Для удаления остаточных количеств фармацевтических соединений, присутствующих в питьевой воде, на всех этапах водоподготовки могут применяться разнообразные способы очистки, основанные на различных физико-химических принципах. В работе приведены результаты экспериментального исследования эффективности удаления с помощью бытовой стационарной системы водоочистки остаточных количеств фармацевтических препаратов – антибиотика левомицетина (хлорамфеникола) и стероидного гормона эстрона – из модельного раствора, приготовленного на основе водопроводной воды с добавлением лекарственных препаратов. Показано, что бытовая система водоочистки обладает способностью существенно снижать остаточные концентрации фармацевтических препаратов левомицетина и эстрона на всем протяжении заявленного производителем ресурса. В секторе бытовой водоочистки установки адсорбционного типа по-прежнему остаются наиболее востребованным типом водоочистных систем, обеспечивающих высокую эффективность удаления различных загрязнителей при минимальных капитальных затратах. To remove residual amounts of pharmaceutical compounds present in drinking water, a variety of purification methods based on various physicochemical principles can be used at all stages of water treatment. The paper presents the results of an experimental study of the efficiency of removing residual concentrations of pharmaceuticals – laevomycetin antibiotic (chloramphenicol) and estrone steroid hormone – from a model solution prepared on the basis of tap water with the addition of drugs, using a home fixed water purification system. It is shown that the home water purification system provides for the significant reduction of residual concentrations of chloramphenicol and estrone throughout the service life declared by the manufacturer. In the household water purification sector, adsorption-type units are still the most in-demand type of water purification systems that provide for the high efficiency in removing various pollutants with minimal capital costs.

In India, water borne diseases are increasing day by day. Nearly, 60% of India’s population has to drink unsafe or impure drinking water. Drinking impure water gives rise to many water borne diseases such as diarrhea, typhoid, etc. Energy crisis is another big issue in our country as India is a developing country. Conventional energy sources are limited and they cause environmental pollution. By using a renewable energy source such as solar power for water purification, we can avoid above mentioned issues as it gives solution to both the problems. Solar water purifiers comes up with a solution to these problem as water gets purified with the help of solar energy. Solar water purifiers are an advancement of the current water purification system. Design methodology of the solar water purifier is presented in this paper. Solar water purifier takes solar power as the input and uses it as a energy source and stores it into the battery. Main components of the proposed solar water purifier are solar panel, battery, heating coil, filtering mechanism, double layer condenser and several water vessels. This purifier uses a filtering mechanism to remove dirt from the impure water and a boiling mechanism to kill organisms present in it. Through this process, pure drinking water is achieved.

: Harvesting solar energy for water treatments has been considered a promising solution for the global community. The shortage of water is a great challenge for scientists due to the increased demand of population. However, the low efficiency of absorber materials is an obstacle in practical applications. In addition, state-of-the-art conventional technologies require optical concentrators and multiple component-based systems, leading to lower efficiency and higher cost. In this review, a low-cost, more reliable, less energy-intensive, and more eco-friendly solar water purification system based on graphene-plasmonic hybrid nanocomposite has been demonstrated. Graphene-plasmonic-based hybrid nanocomposite has been utilized to achieve pure water from wastewater. Such hybrid nanocomposites have the ability to clean polluted water very efficiently due to their excellent properties such as higher surface area, low concentration, and working ability. Furthermore, the development of a solar water purification system has been achieved through optimized hybrid nanocomposites.
