Twin Alternating Carbon Filtration 150 GPM - USA

Product Description

Pure Aqua successfully supplied ExxonMobil in Texas, USA with a skid mounted Twin Alternating Activated Carbon Filtration System to remove chlorine from the water. The twin alternating activated carbon filtration system is composed of epoxy coated steel tanks designed with an advanced PLC control panel, chlorine analyzer, butterfly actuated valves, PVC sch 80 face piping, high quality acid washed coconut activated carbon media, differential pressure switch & gauge, in/out pressure gauges, and drain line flow controls (DLFC). The system was selected from our MF-1000 Series. ACF-72A uses a 72” diameter tank to handle a flow rate of 150 GPM.

Since its startup, the filtration system has been running smoothly with minimal trouble-shooting. For satisfactory results, the system utilized the following grades of media: Acid Washed activated Carbon and Gravel.

Acid washed activated carbon strives to reduce the undesirable tastes, odors, and colors present in many chlorinated water supplies. For many years, acid washed activated carbon has been successful in reducing free chlorine from water supplies. It requires periodic backwashing to remove accumulated suspended matter and to re-grade the filter bed. Activation is carefully controlled to produce exceptionally high internal surface area with optimum pore size for the adsorption of a broad range of high and low molecular weight organic contaminants.  To obtain maximum efficiency of the activated carbon in the adsorption process, it is recommended to have the greatest possible surface area in the smallest practical volume.

Gravel is a naturally occurring, river washed, glacial deposit product. It contains excellent chemical properties such as high silica content and low soluble calcium, magnesium and iron compounds. It has a highly spherical shape that encourages good flow and equal distribution in support beds. Gravel is low in soluble impurities and it will maintain the quality of the treated water, especially in softeners. Gravel comes in three grades: coarse, medium, and fine. When loaded in the tanks, it must be loaded by grade: First coarse, then medium, then fine.

Activated Carbon Filtration Systems are great sources for removing odor, chlorine, color, and taste from water. These systems utilize granular activated carbon to carry out these tasks. Granular activated carbon (GAC) is a good media to reduce natural and synthetic soluble organic compounds from water and wastewater. However, it is considered to be costly and expensive media and periodically must be replaced. Finding ways to maximize the performance and life of carbon can save significant amount of money. Activated carbon is the most common method of removing odor, chlorine and color from water. However, it is not always the most appropriate method to remove color. Sometimes the color in water comes from silt or very small particles of suspended solids and not from dissolved solids. The particles imparting the color are so small they cannot be seen with the naked eye, but they do exist. If color results from these small particles, activated carbon is not the right way to remove it.

A multi-media filter or dual layer filter is the most efficient and most economical selection. It is always a good design to protect your activated carbon media filter by using a multi-media filter as a pretreatment, this will prolong the life of your GAC media, and saves your money.

Pure Aqua| Twin Alternating Activated Carbon Filtration System USA 150 GPM 03:40

Pure Aqua, Inc. designs and manufactures water treatment systems in addition to a twin alternating activated carbon filtration system. This twin alternating activated carbon filtration system was designed to filter 150 GPM in USA in March 2013. This system's main purpose is to prepare feed water for reverse osmosis. There are four kinds of media used in this filter, granular activated carbon, course grade, medium grade, and fine grade. The backwash can be activated by a pressure drop, setting a time, or chlorine levels in the filter. For more information click here:
