Industrial Sea Water Reverse Osmosis (SWRO) Singapore Yacht Club

10:23 PM

INTRODUCTION

In December 2006, Pure Aqua successfully supplied 3 X 50TPD 440V/3Ph/60Hz & 6 X 30TPD 415V/3Ph/50Hz customized Industrial Sea Water Reverse Osmosis systems to the Singapore Yacht Club.

SYSTEM AND PROCESS

Feed water to the system is from sea water, TDS of about 35,000 PPM. The SW-13K-1380 & SW-8.0K-1280 Sea Water Reverse Osmosis systems were modified from our SWI Series. Pre-treatment of raw water includes media filtration to remove suspended solids down to 25 microns and antiscalant dosing to prevent fouling the membranes. The Seawater Reverse Osmosis (SWRO) units consist of 5-micron cartridge filters to reduce feed water Silt Density Index (SDI) and to limit the SS to 5 microns. The unit also has an advanced microprocessor with permeate water divert option and fresh water flush.

PERFORMANCE

The SW-13K-1380 SWRO system was designed to produce 50cmd and the SW-8.0K-1280 SWRO was designed to produce 30cmd, both at 35,000 ppm feed TDS. Since the time of its start-up in February 2007, the plants have been running smoothly with minimal trouble-shooting.

INTRODUCTION

In December 2006, Pure Aqua successfully supplied to a major power plant in HI, USA, a water treatment package consisting of twin Multi-Media Filters, model: MLF-48A-F-twin, Pretreatment System, Double Pass Reverse Osmosis Unit System, Electrodeionization System (EDI), Storage System, and RO cleaning system.

SYSTEM AND PROCESS

Pre-treatment of the feed water includes filtration using twin multi-media filters to remove sediment down to the 10-20 micron range providing service feed water with a flow rate of 126 GPM at a maximum operational pressure of 100 psi. Filtration using Activated Carbon Filters with Carbon block cartridges removes chlorine, silt, taste, odor and sediment. The use of antiscalant dosing minimizes the precipitation of sparingly soluble sulfate salts (Calcium and Barium Sulfate) and silica oxide. The double pass RO unit comes with a high pressure pump to boost the feed pressure, 5-micron cartridge filter to remove the last traces of suspended solids and reduce the feed water SDI to less than 3. The unit also comes eq uipped with an Advanced Allen Bradley PLC 14? color touch screen control panel, the control panel has an air condition due to the tropical severe weather condition. Electro-deionization removes ions from aqueous streams to achieve a water quality of 18.6 Mega Ohms then the product pump skid takes the product water from the EDI system to a product storage tank. The RO cleaning system is used to clean the membranes in three pressure vessels at a time.

PERFORMANCE

From a feed TDS of about 300 mg/L at temperature range of 27?C, the power plant produces 60gpm of ultra pure water at 18.6 Mega Ohms. Since the time of its start-up in March 2007, the plant has been running smoothly with minimal trouble-shooting.
