2 Entipur Monitor TM Entipur Monitor Manifold includes bypass valve, 1 FNPT fitting kit, Meter, Meter Control, transformer and S1, S2, S3 sample taps. Choice of Filter Media available to suite your application needs Down-flow Tank Heads Inside each Mineral Tank is an upper distributor screen and lower distributor screen with 1.05 distributor tubes. The Entipur Monitor TM uses best management practices for treating drinking water for contaminants such as arsenic, uranium, V.O.C. s, and radium, and integrates twin tanks, water sample ports, and meter control into one system. Meter Control monitors water use with 80% threshold yellow flashing light, 90% threshold red flashing light, and beeps when threshold gallons is met. Also displays flow, total flow and peak flow.

3 Entipur Monitor TM The Entipur Monitor uses best management practices for treating drinking water for contaminants such as arsenic, uranium, V.O.C. s, and radium, and integrates twin tanks, water sample ports and meter control into one system. The Entipur Monitor features: Twin tank back up protection Water Use Alarm Sample Valves Packaged with meter control (Part Number BUB080) which can be used for a water use alarm, flow switch, air pump, and feed pump operation* with the following features: Displayed real time flow rate, GPM Total accumulated flow, Gallons Records peak flow, GPM Peak Power On Green Light Adjustable threshold gallons prompt 80% Threshold Amber Light 90% Threshold Red Light 100% Threshold flashing Red Light 100% Threshold Audible alarm 100% Threshold 12 V AC Output Set Volume/Set Time 12 V AC Output Flow Switch 12 V AC Output Adjustable 4-20 ma output flow rate signal 1-40 GPM +/- 5% Easy touch programming Multiple Quick Connect fittings 1 High Flow Turbine Meter Glass Reinforced Polymer Housing *For use with many different treatment medias, contact us for application engineering Media Specifications Model # Monitor 10T Monitor 15T Monitor 20T Monitor 25T Selection per application Tank Size, In. 9x48 10x54 12x52 13x54 Overall Height, In Inlet Height, In Pipe Size In/Out*** 1 MNPT 1 MNPT 1 MNPT 1 MNPT Peak Flow, GPM ** ** ** ** Shipping Weight, lbs Mineral Volume, Cubic Feet Per Tank ** Selection per application, manifold and tank heads only is 25 GPM at 8 PSI pressure drop ***Bypass and 1 MNPT fitting kit standard Railroad Ave. Exeter, NH 03833

4 Arsenic Removal: LayneRT Arsenic Removal Media Meet the Arsenic MCL Using the Best Arsenic Removal Media Available The LayneRT difference: LayneRT LayneRT is a long lasting, high capacity has been developed as a significant technology that provides rapid improvement in the efficiency and adsorption kinetics without generating longevity of adsorptive arsenic media, any fines. Not only does LayneRT thus lowering the operating cost provide optimal flow dynamics, no associated with removing arsenic backwashing (no onsite residuals), and a (arsenate and arsenite) from water. Its low pressure drop, but it is also ideal blend of selectivity and durability regenerable, thereby mitigating the means that LayneRT can reliably and liability associated with waste disposal. efficiently reduce arsenic to safe consumption levels. LayneRT - the Best Selection for Blended or Full Flow Arsenic Treatment Breakthrough to 10ppb in Processed Bed Volumes The LayneRT Difference: NSF/ANSI Standard 61 Certified Longer lasting Higher capacity Lower operating cost Proven iron chemistry No fines No backwash Regenerable Limits liability associated with disposal Optimal flow dynamics Rapid adsorption kinetics Low pressure drop Spent media passes Toxicity Characteristic Leaching Procedure (TCLP) Component Well #14 mg/l Well #18 mg/l As ph SiO 2 Fe Mn SO 4 PO 4 Species < <0.150 V:100% < <0.250 V:100% Layne Christensen Company Wells located in Tuscon, Arizona area.

Media comprised of granulated materials are friable and generate fines, which can lead to increased backpressure during operation requiring backwash, additional system complexity and more frequent maintenance. No Backwash Required: Backwash requirements add operational complexity, and generate fines containing an arsenic residual. Arsenic Residuals: LayneRT requires no backwash and does not generate arseniccontaining fines. Disposal: LayneRT in residential systems may be returned for environmentally responsible disposal. Spent LayneRT in municipal systems is regenerable. Although most spent media pass TCLP, research supports that they leach arsenic under actual landfill conditions. TCLP Underestimates Leaching of Arsenic from Solid Residuals Under Landfill Conditions Ghosh A., Mukiibi M., Ela W., Environ. Sci. Technol., 2004, 38(17), pp Regenerable: Regeneration lowers long-term operating and maintenance costs and reduces the volume of solid waste disposal by a factor of ten! The Layne Media Assurance Program The annual media regeneration costs of PES systems using LayneRT can be determined by completing a pilot test. Our Pilot/Performance program is unique in the industry and is illustrative of our confidence in our technologies and in the systems that we install. Pilot evaluations, which are usually completed in 3-6 months, provide enough information for Layne to warrant your annual media regeneration costs under certain conditions. Minimum Contact Time: A lower contact time enables systems using LayneRT to have a smaller system footprint, reducing facility requirements and system costs.
