NCS Explains Dewatering, Water Treatment and Water Discharge

The team at NCS is often asked why is water treatment and water discharge such an important part of a dewatering site or a well-pointing locations.

Here is a quick summary of the areas concern in dewatering and well-pointing projects that the NCS Fluid Handling Systems team of engineers and design group consider when designing a systems and why the skilled team of technicians follow when it comes to standard operating procedures, for optimal systems operation effectiveness and performance.

During the course of dewatering activities treatments systems are incorporated for a number of reasons and why a proper system design is important from the onset of project kickoff.

Industrial water treatment with iron removal is a process used to remove excess iron from water that is used in industrial processes. This is important because iron can cause several problems such as discoloration, foul taste, and odor, clogging of pipes and other equipment, and corrosion of metal surfaces.

The process typically involves adding chemical oxidants to the water, which cause the iron to convert into a form that can be easily filtered out. The most used oxidants are chlorine and hydrogen peroxide. Once the iron has been oxidized, it can be removed through filtration, settling, or by using special media, such as manganese greensand.

In conclusion, industrial water treatment with iron removal helps ensure that the water used in industrial processes is free from harmful levels of iron and is safe for use in various applications.

Additionally the discharge criteria refer to the limits on the number of pollutants that can be released into freshwater areas such as rivers, lakes, and streams. These criteria are established to protect the quality of freshwater resources and ensure that they are safe for human consumption, as well as for the aquatic life that depends on them.

Here are some common discharge criteria that are used in freshwater areas:

1. Total Suspended Solids (TSS) - This refers to the number of solid particles that are present in the water and can cause water clarity issues.
2. Biochemical Oxygen Demand (BOD) - This measures the amount of oxygen that is required by microorganisms to break down organic matter in the water. High levels of BOD can deplete oxygen levels in the water, causing harm to aquatic life.
3. Chemical Oxygen Demand (COD) - This measures the amount of oxygen that is required to break down chemicals in the water. High levels of COD can be toxic to aquatic life.
4. pH - The pH of water is a measure of its acidity or basicity. Fresh water areas typically have a pH range between 6.5 and 8.5.
5. Total Nitrogen and Total Phosphorus - High levels of these nutrients can lead to excessive growth of algae, which can cause oxygen depletion and harm to aquatic life.
6. Heavy Metals - Heavy metals such as lead, mercury, and cadmium can be toxic to aquatic life and human health.

These are some of the commonly used discharge criteria in freshwater areas. It is important to monitor and control the levels of pollutants in the water to ensure that they meet the discharge criteria and do not harm the environment or human health.
