The Water Purification

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes.Water purification may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi as well as reduce the concentration of a range of dissolved and particulate matter.

The standards for drinking water quality are typically set by governments or by international standards. These standards usually include minimum and maximum concentrations of contaminants, depending on the intended use of the water.

Pursafet water filter cartridges are designed to meet the requirement of NSF and FDA-compliant standard.Our carbon block filters are an ideal choice for a wide range of residential, food service, commercial and industrial application.

Things You Need To Know About The Activated Carbon Blocks

Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions.

Due to its high degree of micro-porosity, one gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq ft) as determined by gas adsorption. An activation level sufficient for useful application may be obtained solely from high surface area. Further chemical treatment often enhances adsorption properties.

In the process of filtering water, activated carbon is often used to remove contaminants and impurities. Carbon is probably the most absorbent material known to human, and it is uniquely efficient because of thousands of tiny pores that can absorb.Carbon filters made from powdered carbon blocks are more efficient than granular activated carbon because the blocks are denser, slowing down the passage of water through them.

The larger surface area created by the block carbon, and the more time the water is in contact with the carbon, the more contaminants are removed.Activate carbon water filters are rated by the size of contaminants they remove. These range from around 50 microns down to .5 microns. The smaller the measurement the more effective the filter.

coconut shell carbon blocks
Different substances are used to make the carbon for these filters, such as bituminous, wood and coconut shell.

Of these, coconut shell is the most expensive, but has been found to also be the most effective. It has the ability to remove even the smallest particles of contaminant.Also, coconut shell-based carbons tend to be harder,more resistant to abrasion, and lower in ash than similar grades of coal-based carbons.
The major advantage with the coconut shell activated carbon is that it is an outstanding material for applications requiring taste, odor and dissolved organic chemical removal from water with suspended particle present.

In addition, its balanced pore structure gives a more efficient adsorption range and it imparts a high “polish” to the filtered water.

Pursafet carbon blocks filters raw materials are from Jacobi high-grade coconut shell based carbon,delivers an unmatched purity and micro-pore volume than than other carbon source.

Pursafet carbon block filters are manufactured entirely from FDA-compliant and NSF certified,making them an ideal choice for a wide range of residential, food service, commercial and industrial applications.
