Water Challenges: The characteristics of chemicals throughout groundwater is determined by the gases and minerals reacting with the water in its generally slow passage through the Earth’s crust. Extensive variations in groundwater quality are brought by many variables in various water sources. Dissolved minerals such as silica and sulphate produce corrosiveness among water which leads to the deterioration of water treatment equipment, steam boilers, water pipes, etc. Measures to avoid this from occurring involves utilizing active agents that work to minimize these unwanted effects and maintaining pH stability in treated water. If properly treated, the feed water will reach a balance where the additional of more dissolved substances will no longer occur.

Applied Solution: Pure Aqua manufactures reverse osmosis systems that are designed to target and eliminate elevated levels of silica and sulphate. Reverse osmosis has become the main water treatment method for the removal of these compounds, desalination, and industrial wastewater. RO systems provide great versatility and ubiquity in complex industrial applications, specifically ones that involve removing scaling and fouling substances such as silica and sulphate.

Low operating cost, compact size, reduced footprint, and high quality production of freshwater.

System/Product: Industrial Seawater Reverse Osmosis

Capacity:24,000 GPD

Water-scarce countries such as Dubai require a large amount of water distribution systems in order to supply their citizens with adequate amounts of freshwater.

From its initial start-up, the SWRO system has been operating accordingly with minimal trouble-shooting. An industrial seawater RO system is designed to eliminate enormous quantities of salt and other contaminants from seawater using a technology called reverse osmosis. The reverse osmosis technology consists of using a high pressure pump which exerts extreme pressure to salty water, pushing it through semi-permeable membranes while rejecting salts and other contaminants from going through. The amount of pressure that needs to be applies relies on the ocean’s specific TDS and temperature. The RO membranes are specifically built to remove particulates while dividing the feed water between purified water and rejected concentrated salts. The salts and the other contaminants are discarded into the brine stream then flushed into a drain. Finally, purified water with 99% less dissolved salts comes out on the permeate side and is ready to be collected.

Dubai needs clean drinking water to provide quality service to their visitors. In addition, the poor consumability of drinking water is directly related with inadequate hygiene environment.

In May 2007, Pure Aqua successfully supplied an Industrial Reverse Osmosis Kit to produce 200 GPM of product from 250 GPM feed, antiscalant chemical dosing, prechlorination and chemical dosing, acid injection dosing, and dechlorination dosing systems. Feed water to the package is processed water with a raw water TDS of about 1,500 PPM. The package design was based on a high rejection TFC spiral wound low fouling membrane. The Reverse Osmosis Kit was selected from our RO-500 Series, model # BW-360K-8680-3 It produces 200 GPM of drinking water with TDS less than 100 mg/L. The Reverse Osmosis Package 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.

Pure Aqua successfully manufactured and supplied to a major water treatment company in Dubai UAE, more than 15 units of Commercial Brackish Water Reverse Osmosis (BWRO) Units to produce different capacities between 1,500 GPD to 6, 000 GPD at a maximum 2000 ppm feed water TDS. Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. To illustrate, imagine a semi-permeable membrane with fresh water on one side and a concentrated aqueous solution on the other side. If normal osmosis takes place, the fresh water will cross the membrane to dilute the concentrated solution. In reverse osmosis, pressure is exerted on the side with the concentrated solution to force the water molecules across the membrane to the fresh water side.

 PERFORMANCE

 From a feed TDS of 2,000 mg/L at temperature range of 25 °C, the system produces from 1.2 to 7gpm of high quality water at less than 100 ppm.

Reverse osmosis is often used in commercial and residential water filtration. It is also one of the methods used to desalinate seawater. Sometimes reverse osmosis is used to purify liquids in which water is an undesirable impurity (e.g., reclaimed waste water, ethanol).

The BWRO Unit consists of TFC spiral wound membranes to have a recovery rate of 60% with an advanced microprocessor control panel.

Water Challenges: Much of the drinking water supplied to Americans are extracted from surface water sources such as lakes, rivers, and artificial water bodies. Surface water sources are preferred over groundwater for the reason of being much easier to purify during the treatment process. However, unlike groundwater which is naturally filtered once pulled out from the ground, surface water is vulnerable and accumulates many unwanted impurities, such as bacteria, parasites, and viruses. For this reason, advanced water treatment such as multi-media filters are required to convert surface water (aluminum reduction from water) into fresh, clean drinking water.

Applied Solution: Pure Aqua has manufactured two sets of stainless steel Multi Media Filters, with each tank having a capacity of 330 GPM, and 660 GPM when used in conjunction. The Multi Media Filters to be used in an airport in Abu Dhabi, UAE and were highly successful in treating the issue of contaminated surface water in the area.

System: Stainless Steel Media Filtration

Large concentrations of suspended solids present results in a reduction in water quality. This outcome occurs in the form of turbidity which produces undesirable effects such as color alterations, smell, and taste issues in the water. Scaling can also result due to suspended solids and significantly hampers the performance of equipment and utilities utilized across industries. For these reasons, multimedia filtration systems are depended upon within applications that require high quality treated water. Media filtration has proven to be the most effective treatment method in regard to suspended solids reduction.

Pure Aqua manufactured and supplied a series of stainless steel filtration equipment for a major water treatment company in UAE.

Media filters are designed and manufactured to rid water of suspended particles as well as remove unwanted taste, smells, or coloring. They are made up of different layers of sand and particles with the intention of grasping the smaller particles imbedded within the water. In multimedia filters materials that are light and course are usually on the top of the filter bed while particles that are heavier and finer are at the bottom. This is a great system when it comes to the filter operating to its full capacity. Because of the way the particles are placed in the filter, the entire filter is being used in the purification of the water.
