Backwashing requires 50% less water & energy
compared to conventional nozzle system
DESALINATION
TECHNOLOGY
(CHEMICAL-FREE)
DESALINATION SYSTEM (PATENTED CHEMICAL-FREE CIP TECHNOLOGY)
RO Membrane Chemical-Free Cleaning
DESALINATION SYSTEM (PATENTED CHEMICAL-FREE CIP TECHNOLOGY)
Operating Parameters
• Capacity Range 500 - 1,000,000 cu.m/day • Seawater TDS 30,000 – 41,000 ppm • Temperature 15⁰C - 32⁰C (59⁰F - 90⁰F) • Recovery 45%
Applications
• Potable water for municipalities and resorts • Water for irrigation – agriculture • Boiler Feed Water (BFW) for various industrial
needs – power plants, refineries and more
BENEFITS & ADVANTAGES
• The rejected brine solution can be used to produce industrial salt.
BENEFITS & ADVANTAGES
• Entire process is chemical-free
• Reduced energy consumption
• Reduced footprint
• Minimal infrastructure investment required
• Modular units for fast & easy installation
• Operational costs reduced by 10%
• Plug & Play installation • No need for chemical
handling nor disposal permits
• Easy operation and maintenance

RECLAMATION
FACILITY (WRF)
TRIVIA: Do you know that the DENR/LLDA Standard for treated
wastewater effluent has remain unchanged since 1978 with the
BOD (Biological Oxygen Demand) of 50 mg/liter?
Do you know that the Philippine population in 1978 was about
20 million as compared to 100 million today?
Do you know that a well maintained and cleaned septic tank can
only reduce the BOD5 by 30% ?
Typical influent BOD5 value is 300mg/l and with 30% maximum
reduction, the effluent BOD5 from septic tanks is 210mg/l;
EPA Guidelines for Water Reuse (2012)
BENEFITS OF WASTEWATER RECYCLE & REUSE
• SM MALLS saves 3.3 Million Cubic Meter
of Water a Year • US Embassy in Manila saves Php 5
Million annually
