Water Treatment Solutions to Protect The Environment

As we continue to face ever-increasing requirements for contaminant-free water, the process of eliminating harmful contaminants for safe disposal or consumption becomes more critical. Contaminated ground or surface waters may be due to a variety of factors such as leaking underground storage tanks, improper chemical disposal practices, or surface water run-off from industrial processes. Heavy metals and other types of contaminants can concentrate in construction dewatering and surface runoff waters. These contaminants can occur due to current or historical chemical processes or may be naturally occurring. Since these contaminants will have a negative impact on human health and ecological risks, their removal from the soil, groundwater, sediment, or surface water through the use of biological, chemical, and physical treatment technologies is critical to restoring the water to a safe and environmentally sound condition.

Frequenty Asked Questions

How often should gas turbine filters be replaced?

This depends on the environment and filter type; however, pre-filters are changed every 3–6 months, while final filters may bechanged once in a year or two. Monitoring pressure drop is key to determiningreplacement timing.

What factors affect the operating life of a gas turbine filter?

Here are some factors:

Ambient dustand pollution levels
Operatinghours and load
Pulse-cleaningfrequency, depending on the type
Humidity andmoisture
Filter mediaand design

How do I know when a filter needs to be changed?

Differential pressure across the filter is animportant aspect in this case. If it increases beyond the set threshold, thefilter may be clogged or need cleaning or replacement.

What is pressure drop and why does it matter?

Pressure drop is the resistance to airflow through afilter. A high-pressure drop reduces turbine efficiency and increases energycosts. Selecting low-resistance filters helps improve performance.
