Those who are generally familiar with this field will immediately embrace the subject as a treatise on solid-liquid separations. However, the subject is much broader, in that the technologies discussed are not just restricted to pollution control hardware that rely only upon physical methods of treating and purifying wastewaters. The book attempts to provide as wide a coverage as possible those technologies applicable to both water e. The methods and technologies discussed are a combination of physical, chemical and thermal techniques. There are twelve chapters. The first of these provides an orientation of terms and concepts, along with reasons why water treatment practices are needed. This chapter also sets the stage for the balance of the book by providing an organizational structure to the subjects discussed.
When we refer to water purification, it makes little sense to discuss the subject without first identifying the contaminants that we wish to remove from water. Also, the source of the water is of importance. Our discussion at this point focuses on drinking water. Groundwater sources are of a particular concern, because there are many communities throughout the U. The following are some of the major contaminants that are of concern in water purification applications, as applied to drinking water sources, derived from groundwater.

Common disinfection methods for water and wastewater treatment are expected to be effective for inactivation of coronaviruses when executed properly. The purpose of this article is to provide water and wastewater utilities with a summary of some of the relevant issues related to coronaviruses treatment with considerations and recommendations to water and wastewater treatment practitioners with respect to coronaviruses in general. It is important to remember that an extensive body of literature on the effectiveness of water and wastewater treatment processes for coronaviruses is not available, and as always, site-specific water-quality and treatment-plant details may result in variation between full-scale effectiveness and research results found in the laboratory.
This book discusses major technological advances in the treatment and re-use of wastewater. Its focus is on both novel treatment strategies and the modifications and adaptions of conventional processes to optimize the treatment of a complex variety of pollutants, including organic matter, chemicals and micropollutants in different water resources, as well as the integration of water treatment with bioelectricity production.
Wastewater or waste water is any water that has been contaminated by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater , and any sewer inflow or sewer infiltration". The characteristics of wastewater vary depending on the source. Types of wastewater include: domestic wastewater from households, municipal wastewater from communities also called sewage and industrial wastewater. Wastewater can contain physical, chemical and biological pollutants. Households may produce wastewater from flush toilets , sinks , dishwashers , washing machines , bath tubs, and showers. Households that use dry toilets produce less wastewater than those that use flush toilets.

Мы обнаружили статистический сбой и хотим выяснить, в чем. Кроме того, - добавила она, - я хотела бы напомнить Стратмору, что Большой Брат не спускает с него глаз. Пусть хорошенько подумает, прежде чем затевать очередную авантюру с целью спасения мира. - Она подняла телефонную трубку и начала набирать номер. Бринкерхофф сидел как на иголках. - Ты уверена, что мы должны его беспокоить.
Too much selenium in the ground water must be treated to meet discharge regulations.
Фонтейн стоял, тяжело дыша. - У нас нет причин ему не верить. - Это прозвучало как сигнал к окончанию разговора.
Сьюзан положила руку на мышку и вывела окно состояния Следопыта. Сколько времени он уже занят поиском. Открылось окно - такие же цифровые часы, как на ТРАНСТЕКСТЕ, которые должны были показывать часы и минуты работы Следопыта.
- Посмотрим, кто ты. Сьюзан прочитала открывшееся сообщение, которое состояло из одной строчки, потом прочитала его еще. ПООБЕДАЕМ У АЛЬФРЕДА.
