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

WASTEWATER

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
