Parts of a Wastewater Treatment System
Wastewater treatment systems contain several parts, each vital for efficient operation. It’s important to understand each part of a wastewater treatment system before planning and constructing one.
Planning a Wastewater Management Project
Early in the planning stage, it’s best to understand all industry standards and regulations thoroughly. Doing so allows for fundamental decision-making, such as determining target purity. Industry standards may be complex when involving high-pollutant wastewater or high purity effluent standards.
Why Is Wastewater Management So Expensive? Important Factors to Consider
Both residential and industrial water treatment can be expensive. Treatment systems utilize advanced technology, often involving large equipment in multistage facilities. Many different factors influence the cost of a wastewater treatment system, including the following:
Increased vs. Decreased System Automation
An increased level of automation serves several purposes. It minimizes the risk of human error and decreases long-term labor costs. High automation may reduce the lifetime operating costs of a wastewater treatment system. Automated equipment and features tend to be more expensive than their manual counterparts. Initial expenses might be greater.
