Drinking Water

Graver Technologies offers water treatment solutions for drinking water from point of entry to point of use, a small community system to municipal systems.

Water Treatment Solutions for Drinking Water

Clean, high quality drinking water is mandated for communities in most countries by the government. Standards have been established for a single home on a well to the largest cities which produce water from wells, surface sources or oceans. In certain instances, such as where nitrates create issues in a single well, or for brackish water along coastal communities, reverse osmosis (RO) is required to produce an acceptable quality of potable water. For surface waters, issues such as cryptosporidium or giardia can be problematic. In other instances, some geographies have lead or other heavy metals present that can be a significant health concern. Among the newest concerns are PFAS, the “forever chemicals”, and microplastics, the risks of which are not completely defined. At Graver Technologies, we have been developing and manufacturing superior water treatment solutions for more than 140 years., so whether the application is point of entry, point of use, a small community system or a municipal system, we have a technology.

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.
