Industrial Brackish Water Reverse Osmosis
Introduction In December 2008, Pure Aqua successfully supplied a skid-mounted Industrial Brackish Water Reverse Osmosis (BWRO) system to produce 50m3/hr product at 77°F using (42) 8"x40" FILMTEC LE-440i membrane elements, (6) FRP pressure vessels 7 elements per each vessel, SS multistage pump, PLC based controls and a digital conductivity and ORP read out, 380V/3ph/50Hz.
Systems and Process Feed water to the system is from bore-well with raw water TDS of about 2451 PPM. The system design was based on high rejection TFC spiral wound membranes. The Brackish Water Reverse Osmosis system was selected from our RO-500 Series, model number BW-320K-6780-3. The Brackish Water Reverse Osmosis (BWRO) unit consists of 5-micron cartridge filters to reduce feed water Silt Density Index (SDI) and to limit the SS to 5-micron size and advanced PLC control panel with touch panel screen. Pre-treatment and post-treatment includes the following:
- Antiscalant dosing to minimize the precipitation of sparingly soluble sulfate
- Multimedia filters to remove suspended solids and reduce turbidity
- Carbon filters
- Cartridge filter with 0.2 micron cartridges
- Filter feed and backwash pumps
- Post UV system
Plant Design Summary
- Application: Bottling
- Total Plant Design Capacity: 1200 m3/day
- Product TDS: General Use = less than 240PPM
- Chemical Treatments: Antiscalant
- Feed TDS: 2451 PPM
- Maximum Pressure: 300psi
- System Recovery: 65%
- Feed SDI: Less than 3
Performance From a feed TDS of about 2451 PPM at a temperature range of 19°C and 28°C, the BWRO skid produces 50 m3/hour of drinking water with TDS less than 240 PPM matching WHO standard for drinking water.

Industrial Reverse Osmosis Waste and Processed Water
Introduction In the Middle East, fresh water is becoming more and more difficult and expensive to obtain. As a result countries are investing in alternatives in water pufication such as reverse osmosis and desalination. In May 2007, Pure Aqua successfully supplied a water treatment package consisting of a Reverse Osmosis System to produce 200 gpm of product from 250 gpm feed, antiscalant chemical dosing, prechlorination chemical dosing, acid injection dosing, and dechlorination dosing systems.
Systems and Process Feed water to the system is processed water with raw water TDS of about 1,500 PPM. The system design was based on high rejection TFC spiral wound low fouling membranes. The Reverse Osmosis system was selected from our RO-500 Series, model number BW-360K-8680-3. It produces 200 gpm of drinking water with TDS less than 100 mg/L. The 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. TFC spiral wound membranes have a recovery rate of 80% with an advanced microprocessor control panel and cleaning system.
Performance From a feed TDS of about 1,500 mg/L at temperature range of 27°C, the system produces 200gpm of high quality water at less than 100 ppm. The water produced will be used in the water park area of the Sports Center in boating areas, pools and water slides.

Industrial Brackish Water Reverse Osmosis System
Introduction The Industrial Brackish Water Reverse Osmosis Unit was manufactured and supplied by Pure Aqua in January 2008 for a major water treatment company in Dubai. The BWRO Unit is capacity of 90,000GPD product water.
Systems and Process Feed water to the system is processed water with raw water TDS of about 2450 PPM. The system design was based on high rejection TFC spiral wound low fouling membranes. The Reverse Osmosis Unit was selected from our RO-400 Series, model number BW-87K-2680. It produces 63 gpm of drinking water with TDS less than 50mg/L. The BWRO Unit consists of 8"x40" Hydranautics ESPA2 membrane elements, Codeline 8" diameter FRP side ported pressure vessels, controlled by microprocessor with digital TDS read out, hi/low tank level switches, hi/low pressure switches, SS multistage pump and inlet shut off valve.
Performance From a feed TDS of about 2,450mg/L at temperature range of 25 °C, the system produces 90,000gpd of high quality water at less than 50ppm. Since the time of its start-up in January 2008, the plant has been running smoothly with minimal troubleshooting.
