  3. 3. Disturbing facts about water pollution• Water pollution is one of the biggest global killers, affecting over 100 million people.That’s comparable to global diseases like malaria and HIV.• Approximately 46% of the lakes in America are too polluted for fishing, aquatic life,or swimming.• The Mississippi River carries an estimated 1.5 million metric tons of nitrogen and 0.5million metric tons of phosphorus pollution into the Gulf of Mexico each year, creatinga “dead zone” in the Gulf each summer about the size of New Jersey.• Each year 1.2 trillion gallons of sewage, storm water, and industrial waste aredumped into U.S. water.• Every day, 2 million tons of human waste are disposed of in water courses.Source: EPA, WWAP, BlackSmith Institute4/25/2013 3info@nanolandglobal.com

  13. 13. Most effective Restoration method: Bio-accelerationWhat are diatoms ?• Diatoms are photosynthesizing algae• They come in many different shapes• They are commonly between 20-200 microns in diameter or length• The cell wall is composed, for the most part, of silica (SiO2)N + P+4/25/2013 13info@nanolandglobal.com

  16. 16. How to provide the right amount of nutrients ?• Nutrient uptake kinetics for photosynthetic algae, including diatoms is a function ofnumerous variables (e.g., amount of sunlight, concentration in P and N, temperature,etc.)• The cell wall of diatoms is constructed by silica deposition vesicles (SDV) withmembranes called silicalemmas.• Without the proper amount, size and geometry of silicate, diatom cells cannotdivide, and its capacity to perform energy producing processes (photosynthesis andglycolysis) are diminished• The already very small (micron-scale) diatoms have tiny portules and chloroplasts intheir cell walls where micronutrients are absorbed and photosynthesis takes place.• Nutrients have to be available in nanoscale geometries to be easily absorbed throughthese portules.4/25/2013 16info@nanolandglobal.com
  17. 17. A revolutionary nanotechnology-based solution !!• Scientists at Nualgi Nanobiotech have developed arevolutionary solution for diatom regeneration : NUALGI• This patented technology, based on the latest nanotechnologymanufacturing methods and years of algal micro-nutritionresearch, provides an optimum blend of micronutrients on anano-silica base.• The incredibly effective NUALGI provides 10 micro-nutrientswith an optimum concentration ratio and nano-size distributionto accelerate diatom regeneration4/25/2013 17info@nanolandglobal.com

  22. 22. Other advantages of using NUALGI• The most eco-friendly restoration method• Low cost(after initial treatment of 1 liter per acre per week for 2 weeks, a half liter per acreper week for 4 to 6 weeks is usually enough• NUALGI can be used in a broad variety of applications:• Fish farming• Sewage treatment• Lakes and streams restoration• Aquariums• Biodiesel• Agriculture and horticulture (in spray form)4/25/2013 22info@nanolandglobal.com
