Industrial Brackish Water Reverse Osmosis SystemReverse 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.

Introduction

In 2006, Pure Aqua successfully supplied, to a major heavy machine company, a water treatment package consisting of a Brackish Water Reverse Osmosis System (BWRO) to produce 80gpm of product from 113gpm feed, twin MLF-48A-F multimedia filters, twin ACF-48A-F activated carbon filters, antiscalant chemical dosing, and dechloronation dosing system.

Systems & Process

Feed water to the system is processed water with raw water TDS of about 4,610 PPM. The system design was based on high rejection TFC spiral wound membranes. The Brackish Water Reverse Osmosis system was selected from our RO-400 Series, model number BW-130K-3680-5. It produces 80gpm of drinking water with TDS less than 100 mg/L.

Performance

From a feed TDS of about 4,610 mg/L at temperature range of 15°C to 35°C, the brackish water plant produces 80gpm of drinking water with TDS less than 100mg/L. Since the time of its start-up in October 2006, the plant has been running smoothly with minimal trouble-shooting.

INTRODUCTION

As municipalities seek new water sources to augment fresh water supplies, water reuse and reclamation are gaining in popularity. Reuse is an economic and environmentally sound solution that uses less energy and reduces overall waste compared to the alternative solution, seawater desalination.

Low-pressure membranes based processes for water reuse have been proven to meet stringent standards. Their advantages include: a physical barrier to biosolids, pathogens, bacteria and nutrients; the flexibility to handle changing wastewater characteristics and plant capacities; fully automated and simple operation; a significant reduction in footprint and operating costs, delivering the lowest cost per volume treated. Low-pressure membranes are commonly used for post-secondary clarification processes for tertiary filtration, and after biological processes such as membrane bioreactors (MBRs).

In September 2008, Pure Aqua successfully manufactured and supplied three Industrial Brackish Water Reverse Osmosis (BWRO) Units for reclaimed water, Dubai, UAE. Brackish Water Reverse Osmosis Units are designed to produce 3 x 2000 m3/day. The complete BWRO Units were supplied with pre and post treatment using advanced PLC control.

Pure Aqua, Inc. modular design and the use of fiber reinforced pressure vessels, Grundfos multi stage SS pump, advanced PLC control panel with colored touch panel, make these modular units one of the most compact units in the water treatment industry.

The overall reverse osmosis water treatment plant design used a total of 378 reverse osmosis low-pressure membrane elements housed in 54 pressure vessel assemblies.

The plant is designed as three identical stand alone operating trains which provide more operating flexibility.

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 that have a molecular weight of greater than 150-250 Dalton.

SYSTEMS & PROCESS

Feed water to the system is processed water with raw water TDS about 1250 PPM. The system design was based on high rejection TFC spiral wound low fouling membranes.

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 pump and TFC spiral wound membranes to reduce the TDS.

PERFORMANCE

The RO membranes remove total dissolved solids (TDS), TOC, BOD and COD after MBR. The RO membrane permits the passage of water molecules but is a barrier to most of the ions, viruses and bacteria in the water.

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 & 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-108K-3580. 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.
