The value of water

Sources of water

Further information: Water supply

1. Groundwater: The water emerging from some deep ground water may have fallen as rain many tens, hundreds, or thousands of years ago. Soil and rock layers naturally filter the ground water to a high degree of clarity and often, it does not require additional treatment besides adding chlorine or chloramines as secondary disinfectants.

2. Upland lakes and reservoirs: Typically located in the headwaters of river systems. But some bacteria, protozoa or algae will be present. Where uplands are forested or peaty, humic acids can colour the water. Many upland sources have low pH which require adjustment.

3. Riverscanals and low land reservoirs: Low land surface waters will have a significant bacterial load and may also contain algae, suspended solids and a variety of dissolved constituents.

4. Atmospheric water generation is a new technology that can provide high quality drinking water by extracting water from the air by cooling the air and thus condensing water vapor.

5. Rainwater harvesting or fog collection which collect water from the atmosphere can be used especially in areas with significant dry seasons and in areas which experience fog even when there is little rain.

6. Desalination of seawater by distillation or reverse osmosis.

7. Surface Water: Freshwater bodies that are open to the atmosphere and are not designated as groundwater are termed surface waters.

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Water purification may reduce the concentration of particulate matter including suspended particles, parasitesbacteria algaeviruses, and fungi as well as reduce the concentration of a range of dissolved and particulate matter.

According to a 2007 World Health Organization (WHO) report, 1.1 billion people lack access to an improved drinking water supply; 88% of the 4 billion annual cases of diarrheal disease are attributed to unsafe water and inadequate sanitation and hygiene, while 1.8 million people die from diarrheal disease each year. The WHO estimates that 94% of these diarrheal disease cases are preventable through modifications to the environment, including access to safe water. Simple techniques for treating water at home, such as chlorination, filters, and solar disinfection, and for storing it in safe containers could save a huge number of lives each year.

Chlorine disinfection

Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use. This problem can be avoided by the use of calcium hypochlorite, which is a relatively safe and effective disinfectant.

Why does a high concentration of saline wastewater have a particularly strong effect on microorganisms?
Why does a high concentration of saline wastewater have a particularly strong effect on microorganisms?
The unit structure of microorganism is cell, and the cell wall is equivalent to semi-permeable membrane. When the chloride concentration is less than or equal to 2000mg/L, the osmotic pressure that the cell wall can withstand is 0.5-1.0 atmosphere. Even if the cell wall and cytoplasmic membrane have certain toughness and elasticity, the osmotic pressure that the cell wall can withstand will not be greater than 5-6 atmosphere. However, when the chloride concentration in the aqueous solution is above 5000mg/L,

Microbial life activities and substance metabolism are closely related to pH value. Most microorganisms are adapted to a pH range of 4.5 to 9, while the optimal pH range is 6.5 to 7.5. When the pH is lower than 6.5, fungi begin to compete with bacteria, and when the pH is up to 4.5, fungi will be completely dominant in the biochemical tank, which seriously affects the sedimentation result of sludge. When the pH exceeds 9, the metabolic rate of microorganisms will be hindered. Different microorganisms have different pH range requirements. In aerobic biological treatment, pH can vary between 6.5 and 8.5; In anaerobic biological treatment, the pH of microorganisms is relatively strict, and the pH should be between 6.7 and 7.4.

What is the pretreatment of wastewater? What are the goals of pretreatment?
The treatment before biochemical treatment is conventionally called pretreatment. Because the cost of biochemical treatment is relatively low and the operation is relatively stable, the general industrial wastewater is treated by biochemical method, and the treatment of wastewater is also treated by biochemical method as the main treatment means.
