Water Reduction

Real water reduction is accomplished by a combination of advancing technologies as well as understanding and personal habit. National Energy Technologies can help you wade through the myriad of products that reduce water flow and usage at the fixture. We endorse and offer equipment like advanced irrigation, waterless urinals. low flow shower heads, automatic faucets and no touch flush valves.This technology is improving and the public is becoming used to using devices like double flush toilets. The automatic "no touch" flush head is now able to be retrofit with an affordable double flush kit. There are millions of these has operating and our water saving conversion kits will pay for themselves quickly. They can easily be installed without even turning off the water.

National Energy Technology is also able to consult on the commercial Water Flow Management Valve. This patented Turbulence Reduction System uses a reverse flow pulse to compress any air that is entrapped in your water system. This propitiatory process will reduce the water meter spin up to 12% and can save tens of thousands on the combined water sewer bills of heavy users.

 This valve is designed to slow water turbulence and compress air. The air in the pipes is plentiful, and it may add up to more than you think. This costly air serves no benefit, it is never requested and there won’t be a refund. Many are surprised to find that every building owner nationwide is faced with the same issue and because no one is aware of it, no one is complaining about it. Ultimately the valve will compress and condition the air and turbulence mixed in the water from the municipality, which can cause the water meter to spin an additional 5 to 10%. It’s true; we pay for the tiny bubbles mixed in with our incoming water supply from the utility. This air has always been a natural component to turbulent rushing water and as it passes through the meter it registers, and it reflects on the water bill. In fact, it is often paid for twice because the incoming water meter read is used to determine both water and sewer expense, in most cases.

    Fortunately new technology has provided an answer to this dilemma. It is based on 18th century principals from Le Chatelier and the Venturi effect. This device is legally installed after the meter on the user’s side. Yet it miraculously is able to compress and affect the air before it passes through the meter. Among other things this system will disrupt the usual swirl turbulence in the line without reducing flow. The device does not vent the air from the line but it does effectively compress it. The product is accepted by most municipalities and completely safe and sanitary. Because this technology is scalable it makes excellent sense for the large or small water user and will generally show an impressive ROI. A Turbulence Reduction System uses a reverse flow pulse to compress any air that is entrapped in your water system. This propitiatory process will have the following positive effects on stabilizing the flow entering your facilities water circuit.

    This device is capable of reducing the meter spin by 5 to 15% 
    Reduce sewer expense (often taken from the incoming meter) 
    It will act as a “Shock Absorber” for incoming spikes of entrapped air   
    It moderates current or seasonal High Water Pressure Conditions
    With any reverse in flow the device also acts as a secondary backflow device

Engineering Description 
  Also Called a Flow Management Device (FMD) the valve uses the flow of water to self-perpetuate an oscillation assembly, without noticeable negative effect on building pressure. The oscillation assembly will create a compression process that generates a backward thrust. The result is that air in water transforms into compacted state. The continuation of this process will alter the air to a maximum compression state. This super compressed air, then resumes travel through the water meter, along with clean flow water, and past our device. After the compressed air has traveled past our device the air will resume its original state of volume.

    The valve design will further influence the flow dynamics by breaking up the flow into smaller jets which change the velocity profile from slightly parabolic (flow faster in the center) to a flat-faced velocity profile where the center flow velocity is slower and the wall velocity faster than normal.

   This technology will also reduce the perpendicular (swirl) velocity vector in the pipe. When fluid travels through a pipe there are two velocity components. The first velocity is the forward linear motion through the pipe. The second component is perpendicular (sideways) to the first velocity. Generally water will flow more quickly in the center of the pipe and slower at the pipe walls. This device modifies the flow into a flat-faced velocity profile where the center flow velocity is slower and the wall velocity faster than normal. The ‘swirl’ velocity component that you see when you flush a toilet is unproductive in the line “pre meter” and will be greatly reduced with proper equipment. It is only a properly sized and custom built turbulence management valve that is capable of manipulating these multiple dynamic flow principles, and results into a solution that offers a multitude of benefits. 

    For commercial businesses who are heavy water users like hotels, prisons, country clubs, assisted living, theme parks, car washes and bottling companies, savings come quickly. They may realize a return on investment under 6 months, on a valve that is guaranteed for ten years. This product is only one of the advanced conservation strategies That National Energy Technologies will consider in their comprehensive approach to their Holistic water reduction program.
