Point of Entry (POE) Products

WTS Group provides solutions for the entire home to reduce arsenic and other contaminants.  Whole household POE treatment is applicable to two basic groups of consumers: (1) those currently connected to municipal water supply (public water system) containing arsenic or heavy metals; and (2) those who obtain water from a private well source containing arsenic or heavy metals.  Another cost-effective consumer option is Point-of-Use (POU) which could address the potable drinking and cooking needs in the home.  Private well owners are faced with some unique challenges:

  • These wells are essentially unregulated and are not subject to the safe drinking water act requirements

  • Due to the minimal testing requirements, owners are often not aware of the presence, concentration, or type of arsenic in their drinking water

  • Consumers generally know little about the potential health affects from long term exposure to arsenic

  • The naturally occurring arsenic in the groundwater in prone areas often has the Arsenic (III) form to some degree which is not removed adequately with conventional technologies

  • Water treatment professionals are often unfamiliar with methods to address arsenic

  • Arsenic is rapidly becoming a real estate transaction issue for property sales in some states

POE Arsenic Treatment and Configuration

For POE applications, the AD33 iron oxide mineral is typically utilized in fixed based adsorption vessels, operating in a downflow configuration with a single or multiple fixed bed pressure vessels containing the media where the arsenic removal occurs.  If a water softener is installed, the placement of the adsorption module is often post-softening, offering the benefits of pre-treatment for iron and hardness reduction.  Life of the media is dependent primarily on water quality, pH, and arsenic levels, but life cycle for a typical home with 30 ppb of arsenic and neutral pH may be 2-4 years before media replacement is required.  Backwashing is performed twice a month typically to “fluff” the bed to prevent channeling.  No arsenic is discharged to the drain during the backwash periodic backwash events.  The figure below shows a typical equipment arrangement for whole house treatment




WTS Group has both media and system options for arsenic treatment for the home.  Please contact us to connect you with one of the Adedge authorized dealers in your area.

The new POE Medallion SeriesTM treatment systems bring household water to a new level of quality and convenience. These packaged residential systems, specifically designed for arsenic and other heavy metal treatment are the culmination of years of experience. The systems utilize an advanced iron oxide adsorption media AD33, for reliable, simple, and cost-effective treatment. No other technology can compare to its simplicity and ease of use for the consumer. The media has a very high operating high operating capacity and works over a wide range of water quality. Media replacement is typically 2-4 years depending on water chemistry and usage. The systems utilize no regeneration chemicals, salt or additives. Only periodic backwashing is required. The spent AD33 media, upon exhaustion, is easily disposed as non-hazardous waste.
