UNIQUE PROPERTIES / PROJECT DESCRIPTION:
Human power can make purified water through membrane filter.
This membrane filter can use back flushing which lasts longer than other purifiers. This product can be used without electricity.
This product can store extra filters.
OPERATION / FLOW / INTERACTION:
1.Let the undrinkable water settle in another container before filtering.
2.After it has settled, use only the water from the upper part of the container and pour the water in the nonpotable collapsible plastic bottle
3.Turn Body upside down to connect the container, and then turn the whole unit upside down again.
4.push the bottle by human weight at right angle
5.repeat pour the water in the bottle and repeat 4.
6.when you feel filter is stopped up than before use, disassemble the bottle and start back-fiushing process
1. disassemble the bottle and terminal tube from body
2. pour filtered water to back-flushing bottle(0.5liter)
3. upside down body and assemble back-flushing bottle to body(L)
4. push the bottle by human weight
PROJECT DURATION AND LOCATION:
For areas where water supply is in need
For any kinds of disaster areas to use rain waters without electicty

PRODUCTION / REALIZATION TECHNOLOGY:
BioCleanAct™ Anti-microbial Master Batch is anti-microbial that MST Develops by much kinds so that can satisfy user's appetite. As concentration anti-microbial of pellet form, is supplied by much kinds in various form such as LDPE, HDPE, PP, ABS, SAN PLA so that can satisfy user's appetite. Apply to various plastics and is suitable to Well-being stationery, infant's needs, life, electronic article and Superior performance about endocrine disrupter is not detection decision and human body safety and various poisonous bacillus were recognized from domestic, outside official recognition test institution can use safety to package film for food, food storage courage, chopping board, cosmetics receptacle, wide application product such as treatment tool.
PE, PP, ABS, SAN, PLA(Biodegradable),
Polyester Chip(Anti-microbial, deodorization, dry & humidity,anion, electromagnetic waves shielding,
Scattered Infrared rays functional fiber emission)
Non-toxic to the human body.
1. Safe from environmental endocrine disrupters.
2. Guarantee excellent anti-bacterial, anti-fungi efficacy.
3. Wide anti-bacterial, anti-fungi, anti-lichen(moss) power.
4. Admirable anti-microbial continuance.
5. Superior resistance to the heat.
6. Acquired all of the test reports in accordance with regulations of US FDA & Korea FDA.
SPECIFICATIONS / TECHNICAL PROPERTIES:
+ additional equipments
The membrane filter of under 0.4 micron can remove 99% of bacteria and germs.
1. In order to use the 0.4 micron membrane filter, the pressure of around 1kgf/cm2(14psi) is necessary.
2. When the membrane filter is used, some particles will accumulate on the surface of the filter. It is necessary to back-flush the filter in order to clean it and not hinder the efficiency.
3.Most undeveloped country cannot use electricity.
4.The system should be user friendly.
1.The necessary pressure is made from the weight of an adult (40-80kg/100-200 lbs). To resist this much pressure the size of membrane filter is 7-10 cm (2.8-3.9 inches) diameter.
2. The necessary pressure for operation is generated by the weight of person. To clean it, turn the system upside down and reverse the pressure to the other side.
Initially it was challenged to find how membrane filters work ideally in an appropriate shape. However, I have decided two cone shapes that are base side back to back so the body creates space for extra filers.
second challenge was back flushing.
membrane expert said back flushing extend use-by date of filters.
upside-down action can makes product could be intuitable for less-educated people in under-developed country.
