Purification Methods

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.

Purification Plant

Since 1972, the Kanamachi Purification Plant has been faced with a “musty odor” problem in water. In 1984, the plant began to treat raw water with powdered activated carbon. However, the concentration of the musty odor substance 2-methylisoborneol (MIB) in raw water varied so markedly that it was difficult to control the dosage of powdered activated carbon. To achieve a more stable and effective removal of the musty odor, the Bureau decided to introduce an Advanced Water Purification system combining ozonation and biological activated carbon (BAC) treatment. On June 25, 1992, we started operation of the facilities. This system, which is the first of these plants in Japan, can remove musty odor to the satisfaction of the customer.

Important Design

This paper presents the design and commissioning of a solar powered water purification system at the Ryan Epps Home for Children (REHC) in Michaud, Haiti. This systemsupplies clean drinking water to the 200 children who live and go to school at REHC and also tothe community in the form of a micro-business. This micro-business is the mechanism for incomegeneration for sustainable system operation. The purifier uses a three stage filtration system witha disc-type sediment filter, a 0.1 micron ultrafiltration membrane, and an ultraviolet light fordisinfection. The backwash cycle extends the life of the ultrafiltration membrane to 4 – 7 yearsbefore a new filter is required. Simplicity in operation was an important design considerationbecause it facilitates local operator training, and understanding. To further ensure completeunderstanding of operation, a pictorial quick-start manual was developed so that operators onlyneed to follow the diagrams laid out on the manual. The design folder with CAD drawings,schematics, datasheets, and troubleshooting guide are left with the local operators. Testingbefore shipping and after installation to ensure proper operation upon installation and on-sitewater quality testing ensures it will promote improved community health.
