Bottled Water

Graver Technologies provides high performance products that ensure microbiological protection, particulate removal, cyst reduction, purity, and great taste.

Innovation Technologies for Bottle Water Production

The demand for bottled water continues to grow as consumers opt for healthier choices for their beverages and as an option to tap water due to the convenience, better taste, and perceived purity. Approximately a quarter of all bottled water comes from municipal supplies, with the rest coming from natural sources like springs and wells. Treatment processes will vary depending on the source as well the presence of organic and inorganic compounds. Graver Technologies can provide a range of innovative purification and filtration technologies to address trace contaminate removal to ensure that the water meets consumer expectations as well as quality and regulatory standards.

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.
