Advances in science and technology led to the physical, chemical, and biological treatment of water and wastewater in the early 20th century"The era of wastewater remediation, recycling, and reuse" 。Since the 1960s. Strong research efforts on regulated pressures and water shortages for fueling have provided valuable insight into health hazards and systems designed to reuse water engineering.

In 1965, the Israeli Department of Health issued rules allowing the reuse of intermediate effluents for the exclusion of vegetable crops and eaten vegetable crops for irrigation of uncooked. In Windhoek, Namibia was guided in terms of extensive research on direct drinkable reuse in 1968. In the United States, a milestone event was the passage of the Federal Water Pollution Control Act of 1972{ PL 92-500)."Restore and maintain the chemical, practical, and biological integrity of the nation's waters"Due to the ultimate goal of zero removal of pollutants into navigable, fishable, and/or] swimmable waters.

During the 1970s and 80s, the potential for health hazards and the need for non-beverage technologies and beverage reuse were strongly studied. These research efforts have resulted in an increase in wastewater reuse programmes in a variety of different regions and the evolutionary implementation of new reuse alternatives. One particularly noteworthy event is that of the United States"Guidelines for water reuse"of the publication.

for the development of the International Environmental Protection Agency and Office. (1992)

In the early 20th century, advances in physics, chemistry and biotechnology led to the "era of wastewater, recycling, and reuse" in water and wastewater treatment Since 1960, in response to stress and water scarcity, an in-depth survey has provided valuable insight into the health risks and systems of water reuse projects In 1965, the Israeli Ministry of Health published regulations allowing for the reuse of secondary effluent from crop irrigation. There are also excluded vegetable crops that can be eaten without cooking Extensive research on direct potable reuse in Windhoek and Namibia in 1968 In the United States, an important event was the passage of the Federal Water Pollution Control Act (PL92 500) to "restore and maintain the chemical, physical and biological integrity of the nation's water resources." "Plus the ultimate goal is to achieve zero flow of pollutants into navigable, fishable, and swimmable water. Between 1970 and 80, there was a strong discussion about health risks and the potential of technical needs about non-drinkable and drinkable reuse.

The results of these studies have led to an increase in the execution of wastewater reuse projects in different places and the development of new reuse things. A notable noteworthy event is the "Water Reuse Guidelines" published by the U.S. Environmental Protection Agency and the Office of International Development Affairs (1992).

This story takes place in the United States many years ago. A young man was drafted into the army, but did not want to be a soldier. When he went for a medical check-up, he pretended that his eyesight was poor.

The doctor pointed to the eye chart on the wall and said, "Please read this line above." ”

What's in the top row? The young man asked.

What table? The young man asked again.

In the end, the doctor decided that the man's eyes were not good enough to join the army.

In the evening, the young man walked in alone while watching a movie and sat in the dark next to him. When the lights came on, the young man noticed that he was next to the doctor who had examined him earlier. He immediately said, "Excuse me, ma'am, is this car going to Main Street?" ”

It's time for me to go.

I'll see you again soon, right?

Don't say that. I said yes, and you have to say yes.

Remember? John? Say it.

Well, goodbye, Savannah.

It's time for me to go.

I'll see you soon, won't I?

Respond to me. When I say, you say too.

Remember? john?

Go ahead. Goodbye, savannah.
