Traitement de l'eau

Always check labeling for certification of contaminant removal from filter products.

Reverse Osmosis (RO) is a common process to produce potable water as a supplemental treatment for a residence or as a large-scale municipal process. While there is some debate on the question, there is no scientific evidence that RO water creates any adverse health effects. RO does remove some minerals such as calcium, magnesium and potassium which are beneficial to health.

Cooling tower systems operate most efficiently when their heat transfer surfaces are clean, but by design, require a large air-_water interface to obtain this cooling and thus the system is subject to four major water treatment concerns: corro_sion, scaling, fouling and microbiolog_ical activity. These waterborne deposits (suspended solids) reduce heat transfer efficiency, which substantially increases the energy cost for operation of chillers.

Many MetSorb(R) adsorbents will remove heavy metals from water and wastewater. Please view our product pages for more information.

Boiling water can actually concentrate contaminants as the water vapor is "boiled off".

Aeration helps remove dissolved gasses and� oxidizes dissolved metals, including iron and hydrogen sulfide, as well as break-down organic molecules and volatile organic chemicals (VOCs)

Many MetSorb(R) adsorbents will remove lead and other heavy metals from water. Please view our product pages for more information.

Graver offers several types of lead removing adsorptive media. These media are used in many styles of NSF certified point of use (POU) filters including; flow through carafe cartridges and carbon blocks as well as in small tanks and pressure vessels for point of entry (POE) or point of service (POS) treatment for lead removal.

Bacterial retention is achieved in a water system using a membrane filter, typically 0.2 micron, which has been validated for bacterial removal. While membranes do retain bacterial, not all membranes are validated to remove bacterial contamination

Reverse Osmosis (RO) membranes work by concentrating contaminants (reject water) and excluding them from the permeate or system water.

The USEPA website contains a lot of useful information to help homeowners and the general public understand water quality https://www.epa.gov/sites/default/files/2015-11/documents/2005_09_14_faq_fs_homewatertesting.pdf

PFAS can be removed with adsorbents and ion exchange resins like MetSorb(R) PFX.

Yes, MetSorb(R) adsorbents have a high capacity for removal of arsenic, lead, zinc and other heavy metals that may be present in construction dewatering projects. Please contact us at [email protected] or at 1-800-533-6623 for further assistance.

Always check labeling for certification of contaminant removal from filter products.

Water filters containing lead removal media typically cost <10 cents for every gallon of water treated.

Reverse Osmosis (RO) Systems can be effective in removing many bacteria and viruses from water systems due to the pore size of the membrane. However, where RO membranes are part of a high purity water system, microfiltration membranes which have been tested for microbial retention are used to further mitigate the risk of bacterial contamination in the system.

One way uranium can be removed is through adsorption. MetSorb(R) HMRG has a selective affinity for uranium.

Many MetSorb(R) adsorbents will remove heavy metals from water. Consult a water treatment specialist for more information.

Water filters containing ion exchange resins and/or activated carbon can remove PFAS chemicals.

Water purification is the process of removing contaminants in water that may create health risks or aesthetic issues, such as taste or odor. These tend to be chemical compounds, both organic and inorganic that may be dissolved or suspended, as well as biological contaminants such as cysts, bacteria and viruses.

Depending on the source of the water, the processes may be very similar in that they may include, bulk filtration, flocculation/coagulation, sedimentation, aeration and subsequent disinfection. Potable water plants typically are from cleaner sources such as wells, rivers or reservoirs and thus less processing is required.

As a reliable and well-proven water treatment solution for municipal, industrial, food and beverage, and healthcare processes, Reverse Osmosis (RO) is a technology that effectively removes a large majority of contaminants from the incoming water. By using a high-pressure pump to increase the pressure on the dirty side of the RO membrane, water is forced across the semi-permeable RO membrane, leaving almost all of the particles and dissolved salts behind in the reject stream.

No PFAS can not be removed with heating or boiling.
