After wastewater has been treated, the Biochemical Oxygen Demand (BOD) typically decreases. This reduction occurs because treatment processes remove organic matter and pollutants that microorganisms would otherwise break down, thus lowering the oxygen demand in the water. A lower BOD indicates that the treated water is less likely to deplete oxygen in receiving water bodies, making it safer for aquatic life.
What else can I help you with?
Do evaporation of salt water cause density to increase or decrease?
The density of water increase after evaporation.
Why the boiling point of water is 98 in Kaghan?
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.

The volume of water increase under 3,98 oC.
Will NH3 increase decrease or no change in the pH when added to water?
The pH deccrease.
Do evaporation of salt water cause density increase or decrease?
During evaporation the density increase.
Does not drinking water immediately after eating help in reducing waste?
Not that i heard of, it might actually increase it but water will help you decrease weight while eating meals.
How is waste water treated in india?

Can waste water be treated the same as natural water?
No, waste water requires much more complex cleaning.
Recycling paper does all but the following?
Recycling paper helps conserve trees, reduce landfill waste, and decrease energy use. It does not increase water consumption.
What cause grass to increase or decrease?
The cause of grass to increase/ decrease is how much you water it and not water it, how much sun light it gets and air.

If you add baking soda to water will the temp of the water increase or decrease?
yes it will slightly increase the temperature
What can cause an increase in the density of ocean water an increase in temperature and a decrease in ocean circulation an increase in temperature and a decrease in salinity a decrease in temperature?
An increase in the density of ocean water can be caused by a decrease in temperature and an increase in salinity, as colder water is denser and saltier water increases density. An increase in temperature can lead to a decrease in salinity through processes like ice melt or increased precipitation, which dilute seawater. Additionally, a decrease in ocean circulation can result from changes in temperature and salinity gradients, affecting the thermohaline circulation. Together, these factors can disrupt ocean ecosystems and climate patterns.
When waste water clean is it really clean?
They are three types of waste water 1. Industrial waste water 2. Black water (Toilets) 3. Grey water (Domestic waste water) Out of those Black water is not treated and the remaining two are treated. Waste water is 99.9% pure and the remaining 0.1% constitute all the waste. While salt water is 95% pure. If we develop a suitable technology we can pure that waste water and can reuse . But up to date Grey water is cleaned by no of processes and the purified water is used for Gardening and Toilet flush
Why the boiling point of water is 98 in Kaghan?
The boiling point of water decrease when the altitude increase and the atmospheric pressure decrease.
