Industrial Wastewater

Graver Technologies offers filtration and adsorption products to remove heavy metals, inorganic and organic contaminants.

Effective Technologies For Contaminant Removal in Wastewater

Most industrial processes produce some type of aqueous-based waste stream. These waste streams must be treated before they are recycled, reused, or discharged into municipal wastewater systems or surface waters due to undesirable by-products that are produced. The type of treatment needed will depend on the type of industrial process and the resulting contaminants present in the waste stream. Inorganic particles such as sand, grit, or metal particles may be relatively easy to remove through the use of filtration technology. Organic contamination such as plant materials, fibers, and food waste may be filterable as well, but many are significant concerns due to environmental persistence or significant environmental/health impact. Pharmaceuticals, endocrine disrupting compounds, hormones, radionuclides from uranium mining, processing nuclear fuel from operating nuclear reactors, per- and polyfluoroalkyl substances (PFAS) as well as toxins such as pesticides, poisons, herbicides have all been demonstrated to present significant concerns. 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.
