Eco-Friendly Sand Filtration Device
With zero emissions, easy maintenance and no need for filter media replacement, the eco-friendly mobile sand filtration device called MOBILE SIPHON TANK (MST) is able to consistently produce high-quality filtered water. As such, potable water is made available for drinking, industrial use and emergency situations, thanks to patented technology referred to as “Siphon Washing Technology.” This technology essentially causes twin vertical and horizontal vortices that agitate sand particles as part of a three-dimensional washing action. The hard sludge layer on particle surfaces is then able to be removed.
The two main benefits of MOBILE SIPHON TANK (MST) are environmental sensitivity and cost reduction. With easy maintenance and zero emissions contributions, MST is making considerable advantages in this industry.
Major Features and Advantages
I. No filter media replacement
Filter media can be used semi-permanently without the need for replacement, with zero need for disposal of dirty, used filter media as industrial waste. Earth-friendly, this filtration device significantly adheres to requirements set forth by ISO14000. In line with environmental standards, MST is safe for use in many applications.
II. Lessened amount of backwashing
MST is able to remove suspended substances via Siphon Washing Technology, conducting backwashing only as needed for rinsing away suspended substances. This means the amount of backwashing water is largely reduced, compared with most conventional sand filtration devices that require frequent backwashing. In addition, the outflow of exfoliated sludge is drastically reduced, resulting in an overall high cleaning effect. Crushing of the media filter is impossible due to the kneading action of the unit.
III. Prevention of filter media fixation
When sewage water containing organic matter is treated by the conventional filter tanks, filter media can’t keep up and may suffer proper functioning as a result. That’s where MOBILE SIPHON TANK comes in: to prevent fixation and keep media perpetually clean through Siphon Washing Technology. This means washing only has to happen for one minute a day.
IV. Low CO2 emissions
MST can cut back on about 10% of CO2 emissions in comparison with traditional sand filtration devices. Why? It doesn’t have to get rid of used media, thereby decreasing the amount of backwashing water and electricity consumption necessary. Certified as “Low CO2 Kawasaki Brand” by Kawasaki-city in Japan, MST is a major contributor to compliance with non-polluting zero-emission efforts.
V. Track records
The Siphon Washing Technology was invented in 1997. Since then, it has been exhibited in major foreign exhibitions, such as IFAT in Germany, Aquatech in the Netherlands, WEFTEC in the US and The Big 5 in UAE. At this time, 100 devices have been applied over the globe, including Japan, German, Korea, Vietnam, Laos, Philippines and Mozambique.
VI. International patent
Nihon Genryo Co., Ltd.’s Siphon Washing Technology has patents in 33 countries currently.
Our Eco-friendly mobile sand filtration device, so-called ‘MOBILE SIPHON TANK’ (MST), can consistently produce high quality filtered water without replacing filter media. High quality filtered water would be available for drinking, industrial use and emergency. This is achieved by our patented technology, so-called ‘Siphon Washing Technology’. This technology creates twin vertical and horizontal vortices that cause sand particles to be kneaded each other in a three-dimensional washing action to remove hard sludge layer on the surface of particles.
1. No need for filter media replacement
Filter media can be used semi-permanently without replacement, because of Siphon Washing Technology. Therefore, there is no need to dispose used filter media as industrial waste. SHIPON TANK is “earth-friendly” filtration device that significantly contributes to a response to ISO14000.
2. Amount of backwashing water can be dramatically reduced
Since MST efficiently removes suspended substances by Siphon Washing Technology and conducts backwashing only for rinsing away the suspended substances, the amount of backwashing water can be significantly reduced, compared with the conventional sand filtration devices.
3. Prevention of fixation of filter media
When sewage and water with high content of organic matters are treated by the conventional filter tanks, filter media usually cannot filter and may stop functioning properly. However, MOBILE SIPHON TANK can prevent the fixation and keep media always in a clean condition by our Siphon Washing Technology (washing is conducted only 1 minute in every single day).
Siphon Tank, which is embedded in MST, can reduce around 10% of CO2 emissions in comparison with the conventional sand filtration devices, because it does not need to dispose any used media and it also can decrease the amount of backwashing water and electricity consumption for operation. Siphon Tank is certified as “Low CO2 Kawasaki Brand” by Kawasaki-city in Japan, because it has made a major contribution to the realization of non-polluting zero-emission efforts.
Technical maturity / Past record of introduction
After inventing Siphon Washing Technology in 1997, it has been exhibited in the major foreign exhibitions, such as IFAT in Germany, Aquatech in Nederland, WEFTEC in the US and The Big 5 in UAE. Currently, more than 100 devices, which adopt Siphon Washing Technology, have been used all over the world, including Japan, German, Korea, Vietnam, Laos, Philippines and Mozambique.
The following materials have to be removed in advance, because surface water is preferable as raw water for the device, such as river, spring and lake water.
– Agricultural chemicals
– Heavy Metals
– Sea water
