Wastewater

Graver Technologies offers filtration and purification solutions for wastewater produced in industrial manufacturing processes.

Water Filtration Solutions for Wastewater

Most industrial processes produce some type of aqueous based waste stream. These waste streams will contain a wide variety of contaminants, from particulates to hazardous materials. Streams need to be treated before they are recycled, reused or discharged into municipal wastewater systems or surface waters. The type of treatment needed will depend on the type of industrial process and the resulting contaminants present in the waste stream. For example, a metal finishing plant will produce a very different waste stream than will a soft drink manufacturer. Graver can work with you to determine the best treatment scheme to address your unique situation.

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.
