ABOUT ARSENIC: According to the US Environmental Protection Agency, “arsenic is a semi-metal element in the periodic table. It is odorless and tasteless. It enters drinking water supplies from natural deposits in the earth or from agricultural and industrial practices. Non-cancer effects can include thickening and discoloration of the skin, stomach pain, nausea, vomiting; diarrhea; numbness in hands and feet; partial paralysis; and blindness. Arsenic has been linked to cancer of the bladder, lungs, skin, kidney, nasal passages, liver and prostate.

EPA has set the arsenic standard for drinking water at .010 parts per million (10 parts per billion) to protect consumers served by public water systems from the effects of long-term, chronic exposure to arsenic.” EPA is considering lowering the standard to 5 parts per billion.If your water comes from a municipal or privately-owned water company that has more than 15 service connections or serves 25 people more than 6 months of a year, they are already testing for arsenic in your water. If you own your own, individual well, you are responsible for testing it. We offer laboratory-testing services for reasonable rates with a highly qualified independent laboratory. The USGS has created the following map showing the level of arsenic in various parts of the country but your specific

Our Arsenic media is extremely selective for arsenic and will typically reduce arsenic concentrations to below detectable limits of 1 ppb. The patent-pending media has very fast kinetics and low-pressure loss and is ANSI/NSF 61 certified.

ABOUT ARSENIC SELECTIVE MEDIAS: Typically in our competitor’s systems arsenic is removed by adding iron or aluminum based coagulants that form large particles (precipitate). The newly formed particulate is filtered out by a variety of methods.

Another popular method used by the competition is a strong base anion resin. In these systems the selectivity for arsenic is lower than the selectivity for sulfate. When sulfate is present (as in almost every potable water supply) and the system is overrun, the sulfate will displace arsenate from the resin and arsenate will appear in the effluent at higher concentrations than in the inlet. This effect is often referred to as “dumping” or chromatographic peaking.

Our media is made up of spherical, gel coated iron particles that have been specifically designed with a large amount of void space between beads leading to very low pressure loss, typically less than 5 psi. Arsenate ions exchanged into our media first enter the gel coating. The arsenic is exposed to and immobilized by the iron and immediately precipitates onto the iron, thus leaving the resin free to react with more arsenic while the iron boung arsenic remains trapped inside. The media will also remove anions such as nitrates, uranium and chromate. The media operates in waters with a pH range of six (6) to nine (9).

GUIDELINES for FEED WATER QUALITY

SYSTEM CONFIGURATION:

We offer a one tank and two-tank design. The USEPA guidelines recommend a two-tank configuration. We strongly recommend the two tanks configuration to provide system redundancy. In the event that the first tank reaches capacity, the fresh media in tank number two will take over. Each tank has an approximate capacity of 900,000 gallons at 35 ppb of arsenic. When capacity is reached, new media is needed ($750 per tank for media). The various tank size options and exterior finishes are shown below:

The various system are priced at: Single Tank up tp 6 gpm = $1,995 Single Tank up to 10 gpm = $2,495 Dual Tanks up to 6 gpm = 3,495 Dual Tanks up to 10 gpm = $4,495
