Pure Aqua Supplied two SWRO Systems to Lebanon

Pure Aqua supplied two sea water reverse osmosis systems SWRO for a major livestock applications for a Lebanese livestock importing company; plant’s capacity is 2 x 6,000 GPD

Process Description

Feed water to the plant is supplied direct from the seawater. Each se water plant capacity is 6,000GPD of product water used for drinking and washing purposes. Plants were designed based on TFC spiral wound membranes, which can handle the salinity of 40,000mg/L.

Pre Treatment

  • Antiscalant Dosing System
  • Automatic Multi Media Filter
  • 50 micron bag filter

Location: Beirut, Lebanon

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.


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.

Systems & 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.


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.

In January 2009, Pure Aqua supplied 2x200m3/day Industrial Sea Water Reverse Osmosis (SWRO) Unit to a major treatment company in Azerbaijan. The complete SWRO Units were completed with advanced PLC, colored touch panel screen, prechlorination, multi media filters, antiscalant dosing, dechlorination dosing, post chlorination, cleaning and flushing system,


Feed water to the system is from sea water, TDS of about 25,000 PPM. The SW-52K-4480 Sea Water Reverse Osmosis Units were selected from our SWI Series.

Pre-treatment of raw water includes filter feed and backwash pumps, variable frequency drive and all necessary equipment to run the system smoothly.

Each of the Seawater Reverse Osmosis Units consists of (2) FRP Protec pressure vessels, (8) 8″ TFC spiral wound membranes, 5 micron sediment prefilter. In addition to Danfoss HP Pump which is manufactured from duplex SS2205 stainless steel alloy, Duplex 2205 High pressure piping, powder coated frame skid.


The SW-52K-4480 SWRO Unit was designed to produce 200m3/day, at max. TDS 25,000 ppm.

Desalination using Seawater Reverse Osmosis (SWRO) membrane technology has become a viable option for the development of new regional water supplies.

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.
