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.

The water purification concept has been an age old phenomenon but today's time is different. Gone were the days when water and air were hardly polluted as there were no mechanized processes as utilized today. The scenario changed after the industrial revolution. Factories were set up in huge numbers and the count is increasing by the day. Do you know where these industrial wastes go to? It is water source, especially rivers, lakes, big drains, etc.! The high use of pesticides used in agricultural fields for increased yield of crops also pollutes the ground as well as underground water. But at the same time inventors have also introduced solutions for the same.

The introduction of effective water purifiers Industrial RO for complete purification of water have brought rays of hope. Had there been no water purifier system, there would have been countless deaths everyday owing to water borne diseases. Only a water purification system with modern purifying mechanism like reverse osmosis and other methods can prove effective in purifying the water, making it organically, physically, and microbiologically safe to drink. If you follow the oldest method of purifying water, i.e. boiling, you may still be safe. But as boiling consumes lot of fuel, it does prove expensive in the long run. And if you reside in the city where you use LPG, consuming boiled water may take a toll on your financial health if your income is low.

This is because you will have to boil the water for at least 20 minutes to ensure that it is absolutely purified. It is affordable to install a water purifier system. Most urban homes are installed with RO water purifiers and users are luxuriating in their routine activities, enjoying a healthy life.

There are counted few companies that offer home demonstration of the desired water purifier once you send an enquiry. Some companies that sell water purifiers run their corporate websites and have customer care centres. You can either send an enquiry online or request an order dialing the customer care/helpline number. Trained executives will turn up at your home, test the water and accordingly recommend the right water purification system. RO water purifiers are available in varied price ranges and in different storage capacities. You can opt for the one that suits your budget and preferences. If you have yet not installed a water purifier, install one today! However, before installing a RO water purifier ensure that you get your input water tested for the TDS level and install a RO water purifier only if the TDS level is very High.

INTRODUCTION

Reverse Osmosis is a pressure driven process that raises the water pressure on the high TDS (source water) side of the membrane to well above the osmotic pressure and forces the water to flow through the membrane to the low TDS (product water) side of the membrane. Reverse Osmosis also known as hyper filtration, is used to purify water and remove salts and other impurities. It is also capable of rejecting bacteria, sugars, proteins, dyes, and other constituents.

SYSTEM AND PROCESS

In August 2008, Pure Aqua supplied Industrial Brackish Water Reverse Osmosis (BWRO) Unit for a major water bottling company in Algeria. The capacity of this Brackish Water Reverse Osmosis Unit is 100,000gpd with TDS less than 120ppm of product water. The Brackish Water Reverse Osmosis Unit was selected from our RO-400 Series. The BWRO consists of FRP Codeline Pressure Vessels, BW30-400 Filmtec 8"x40" TFC Spiral Wound Membranes, SS multi stage CRN Grundfos pump and advanced PLC control panel. The system included all pre and post treatment equipment such as prechlorination dosing, multi media filter, antiscalant dosing, dechlorination dosing, post pH dosing, and post UV sterilizer.

PERFORMANCE

From a feed TDS of about 5,000 mg/L at a temperature range of 19?C and 27?C, the BWRO skid produces 100,000gpd of drinking water with TDS less than 120mg/L. Since the time of its start-up in October 2008, the plant has been running smoothly with minimal trouble-shooting. Pure Aqua is well known in supplying the highest quality RO systems within the water treatment industry, all stainless steel pipes are passivated and electro polished, the skid is sand blasted, primed and fused or powder coated. Pressure vessels and membranes are manufactured in USA.

INTRODUCTION

Seawater reverse osmosis system was manufactured and supplied by Pure Aqua in March 2008 for a water treatment company in Yemen, the end user is a major shopping mall in Yemen. The total capacity is 40,000gpd of product water used for drinking, cooling tower and irrigation purposes.

SYSTEM AND PROCESS

The SWRO system was completed with advanced PLC control panel, flushing system, and pre & post treatment systems, all skid mounted system. Feed water to the system is from seawater, TDS of about 42,000 PPM. The SWRO system was modified from our SWI Series. The system design was based on high rejection TFC Spiral wound low fouling membranes.

PERFORMANCE

The desalination plant produces 40,000 GPD of drinking water with TDS less than 350 mg/L from feed water with a TDS of about 42,000 mg/L at temperature range of19 to 27?C. Trials concluded that acid injection could be suspended without affecting the operations of the plant. From its initial start-up in Dec 2008, the plant has been running smoothly with minimal trouble-shooting. As a result, the mall has a reliable and steady supply of potable water at a cost far less than shipping water to the site.
