Products equipment Chemical products

• APF Active Poly Floc
• inorganic flocculent, replaces PAC poly aluminium
  chloride
• Much more effective than PAC
• Coagulates and flocculates organic matter
• Precipitates phosphate and arsenic
• Applications
• Inject into the water before AFM or sand filters,
  best results achieved when used with a ZPM ( Zeta
  Potential Mixer)
• Swimming pools
• Aquatic displays
• Industrial water and grey water
• Cooling towers
• Virtually any application that uses sand or AFM
  filters

Products equipment NoPhos

• Nophos, for the removal of phosphate and arsenic
• NoPhos is a special coagulant / flocculent that
  also precipitates phosphate and arsenic. The
  precipitate is then removed by AFM mechanical
  filtration
• NoPhos is included in APF, however if the
  phosphate levels are very high then the water
  should be treated with NoPhos before moving on to
  APF
• Once phosphate has been removed bacteria and
  algae can not grow
• Applications
• General water treatment
• Fountains and aquatic features, keeps the water
  clean and clear, even without filtration
• Phosphate removal in aquaria, wastewater, lakes
  ponds
• Swimming pools, natural and chlorine pools
• Cooling towers and water systems

• Alternative to chlorine for water treatment
• Can also be used with chlorine, will reduce
  chlorine demand
• Oxidises and disinfects
• Coagulates and flocculates ve charge chemicals
  and solids
• Increases the zeta potential of water
• Increase the zeta potential of all wetted
  surfaces and makes then self cleaning and self
  sterilizing
• Can stabilize chlorine or hydrogen peroxide
• Applications
• Swimming pools chlorinated or natural
• Ponds and fountains
• Aquatic features
