Description
Product Features
9-inchx48-inch resin tank
In/out control valve
Bypass Included
1 cubic foot LayneRT Arsenic Media
Choice of connection
The upflow system eliminates the need for backwashing or electricity to operate. Additionally, the system requires no chemicals or additives. This results in a low maintenance system with low operating costs.
LayneRT is comprised of a hybrid resin bead that is attrition resistant and does not generate fines. It has been developed as a significant improvement on the efficiency and longevity of adsorptive arsenic media, thus lowering the operating cost associated with removing arsenic. Its ideal blend of selectivity and durability means that it can reliably and efficiently reduce arsenic to safe consumption levels.
Removes arsenic levels up to up to 300 ppb (.300 mg/L or ppm).
(If As+3 is present it is recommended that you oxidize the water prior to the arsenic removal media for optimal results)
These systems are intended for water supplies with minimal levels of other contaminants. See the "More Info" tab for these contaminant levels and the different methods of removing them prior to the arsenic system.
Treats a continuous flow rate of 3.75 GPM and maximum flow rate of 7.5 GPM peak flow
Simple head eliminates moving parts to reduce maintenance costs
Designed for 2 bathroom and 2-3 people and/or homes with flows matching system capacities
Simple system connections and detailed installation instructions allow most homeowners to install this system themselves. For those who prefer to leave the work to a professional, most plumbers can install the system in 1-2 hours.
Product Description
LayneRT has been developed as a significant improvement on the efficiency and longevity of adsorptive arsenic media, thus lowering the operating cost associated with removing arsenic (arsenate and arsenite) from water. It&roquo;s ideal blend of selectivity and durability means that LayneRT can reliably and efficiently reduce arsenic to safe consumption levels. LayneRT is a long lasting, high capacity technology that provides rapid adsorption kinetics without generating any fines. Not only does LayneRT provide optimal flow dynamics, no backwashing (no onsite residuals), and a low pressure drop, but spent media passes Toxicity Characteristic Leaching Procedure (TCLP), thereby mitigating the liability associated with waste disposal.
- NSF/ANSI Standard 61 Certified
- LayneRT is comprised of an NSF certified hybrid resin bead
- Long lasting
- Highest capacity
- Treats arsenic levels up to 300 ppb (.300 mg/L or ppm)
- Lowest operating cost
- Proven iron chemistry
- Hydrous metal oxides are the industry accepted chemistry for binding arsenic
- No fines
- LayneRT is attrition resistant and does not generate fines
- No backwash
- Backwash requirements add operational complexity, and generate flues containing an arsenic residual
- Optimal flow dynamics
- Rapid adsorption kinetics
- A lower contact time enables systems using LayneRT to have a smaller system footprint
- Spent media passes Toxicity Characteristic Leaching Procedure (TCLP)
- Low pressure drop
- LayneRT allows for higher service flows, unlike medias comprised of granulated materials, which are friable and generate flues. This can lead to increased backpressure during operation requiring backwash
More Info
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.
Higher levels of arsenic tend to be found more in ground water sources than in surface water sources (i.e., lakes and rivers) of drinking water. The demand on ground water from municipal systems and private drinking water wells may cause water levels to drop and release arsenic from rock formations. Compared to the rest of the United States, western states have more systems with arsenic levels greater than EPA’s standard of 10 parts per billion (ppb). Parts of the Midwest and New England have some systems whose current arsenic levels are greater than 10 ppb, but more systems with arsenic levels that range from 2-10 ppb. While many systems may not have detected arsenic in their drinking water above 10 ppb, there may be geographic "hot spots" with systems that may have higher levels of arsenic than the predicted occurrence for that area.
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. Water systems must comply with this standard by January 23, 2006, providing additional protection to an estimated 13 million Americans.
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.
When it comes to removing arsenic from your drinking water, there are several options depending on your application and contaminant level. The EPA has stated that the following methods have proven to be effective for removing arsenic to below 0.010 mg/L or 10 ppb: adsorption media, ion exchange, coagulation/filtration, oxidation/filtration, and point-of-use or point-of-entry treatment using activated alumina or reverse osmosis. The LayneRT arsenic removal media is an adsorbtion media.
