WHOLE HOUSE CARBON, SEDIMENT AND IRON FILTERS

CARBON FILTERING

 

is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption.

Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media. One pound (454 g) of activated carbon contains a surface area of approximately 100 acres (~40 Hectares).

Activated carbon works via a process called adsorption, whereby pollutant molecules in the fluid to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for water purification and in air purifiers. 

Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water.

Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometers.

 

SEDIMENT, TURBIDITY BACKWASH FILTER

next Sand offers a single bed media made from high purity Clinoptilolite, which delivers superior performance over conventional filter sands or multimedia, and at a lower cost. The material is mined in Western USA and then highly processed and graded; the resulting product is hard and stable with a high surface area and micro-porous character in addition to surface micro-crystals making it an ideal filter media. next Sand has high filtration performance at <5 microns compared to 12 to 15 micron for multi media. It also has a higher flow capacity, typically three to four times that of multimedia. This higher flow rate means a greater performance can be achieved from existing vessels when upgraded with next Sand, or for new applications, smaller filter vessels would be required to achieve the same results. Filtration through the entire media bed depth provides more than twice the capacity of multimedia filtration. It has a higher dirt holding capacity so requires less frequent backwashing, leading to reduced downtime. Lighter weight and lower volume requirement means lower capital and shipping costs than multimedia and the product also lasts longer. The media isn’t consumed in the filtration process; a simple periodic backwash will keep the media clean and operating efficiently for five years or more.
