2 Industrial Brackish Water Reverse Osmosis Units Egypt

INTRODUCTION

In December 2008, Pure Aqua successfully supplied two Industrial Brackish Water Reverse Osmosis (BWRO) Units for Coca Cola Company, Egypt. Brackish Water Reverse Osmosis Units or Industrial RO are 634,080 GPD product water. The complete BWRO Units were supplied with pre and post treatment using advanced PLC control, colored touch panel, data acquisition software, and soft starters. Water is one of the cornerstones of the beverage industry and the quality of the raw water can make or break the quality of the beverage. Beverage manufacturers of beverages and bottlers of mineral water will place entirely different requirements on the composition of the raw water that they need. However, whatever the type of beverage you are involved in, the user will require hygienic, perfect water for production or filling. It must not contain anything that will influence smell or taste, cause haze, influence the manufacturing process or leave corrosion deposits in the system or on bottles.

SYSTEM AND PROCESS

Feed water to the system is processed water with raw water TDS about 2451 PPM. The system design was based on high rejection TFC spiral wound low fouling membranes. The Industrial Brackish Water Reverse Osmosis Unit was selected from our RO-500 Series; model number BW-320K-7680-3. It produces 50m3/hr @TDS < 100 ppm from raw water. The Brackish Reverse Osmosis unit consists of 5-micron cartridge filters to reduce feed water Silt Density Index (SDI) and to limit the SS to 5-micron size. It also includes RO membranes feed high pressure CRN Grundfos pump and TFC spiral wound membranes to reduce the TDS.

PERFORMANCE

The RO membranes remove total dissolved solids (TDS) from the source water. The RO membrane permits the passage of water molecules but is a barrier to most of the ions in the water.
