Anion Exchange

There are many ways to remove Anion based contaminants. Listed below are some of the ways we use to treat these water problems. 

The SBG2-HP by ResinTech is a high purity chloride form type 2 gel strong base anion resin. The HP (high purity) designation means it is Gold Seal Certified by the WQA for use in potable water applications. This media is highly effective at Arsenic reduction when paired with its appropriate equipment.

The ASM-10-HP by ResinTech  is a chloride form arsenic selective hybrid anion exchange resin. ASM-10-HP has hydrated iron oxide monoatomically dispersed throughout the polymer giving the product hybrid properties and exceptional capacity for certain anions. ASM-10-HP is intended for arsenic removal although it does remove uranium and other trace level contaminants. ASM-10-HP has been Gold Seal Certified by the WQA for use in potable water applications. For optimal performance, it is recommended to install two vessels in a lead/lag configuration. The GPM can be increased by adding more systems in parallel.

The A520E by Purolite is a WQA Certified ion exchange resin is a macroporous strong base anion exchange resin specifically designed for the removal of nitrates from potable water. Its macroporous matrix and specialized ion exchange group functionality provide exceptional nitrate selectivity, making Purolite A520E particularly effective even in the presence of moderate to high concentrations of sulfate. This resin outperforms standard exchange resins in nitrate removal.

The A300E by Purolite is a WQA Certified ion exchange resin, which is manufactured to reduce Sulfates in drinking water. In the ion exchange process, as water moves through the media, the Sulfate ions are replaced with chloride. The source of chloride is from the salt used to regenerate the unit. Our regenerable treatment systems offer long-term, sustainable, and cost-effective contaminate reduction.

Nitrates are naturally occurring compounds that are formed when organic matter decomposes and is also found in fertilizers. Nitrates are very soluble and do not bind to soils, so they can easily get into groundwater. Nitrates in drinking water are colorless, odorless, and tasteless. 

High Nitrates in water can cause serious illness, especially in babies, children, and adults with a certain type of enzyme deficiency.

Arsenic is a chemical element with the symbol As and the atomic number 33. It is a metalloid and one of the pnictogens. Arsenic is a notoriously toxic heavy metal. It occurs naturally in our local ground water, mainly caused by volcanic ash layers underground.

The United States' Environmental Protection Agency states that all forms of arsenic are a serious risk to human health. The United States' Agency for Toxic Substances and Disease Registry ranked arsenic number 1 in its 2001 prioritized list of hazardous substances at Superfund sites. Arsenic is classified as a Group-A carcinogen

Sulfate occurs naturally in many groundwater sources. As water moves through soil and rock formations containing sulfate minerals, some sulfate dissolves into the groundwater. High sulfate levels can lead to gastrointestinal discomfort, including diarrhea. Taste and odor – Sulfates can give water a bitter taste and sometimes a noticeable odor, making it unpalatable for consumption.

The U.S. Environmental Protection Agency (EPA) has set a secondary maximum contaminate level (SMCL) for sulfate in drinking water at 250 mg/L. This standard is based on taste, odor, and aesthetic considerations rather than health effects.
