Water Challenges: As part of our project’s initiative in Qatar, delivering clean water through our custom-designed well water treatment systems were required in several different locations. Contaminated water from wells were drawn into our system, requiring purification of the polluted water source prior to releasement on-site. Pure Aqua’s well water treatment systems are manufactured to supply industrial sites with as much water purification and reverse osmosis systems for hotel and industrial use, whilst preserving sodium chloride less than 100 ppm. Hotel industries require clean water for many applications such as: showers, kitchens, laundries, swimming pools, boilers and fountains.

Applied Solution: Pure Aqua manufactures top-rated reverse osmosis and multi-media filters with supreme flow rates and especially simple backwash properties that are able to filter down to 20 microns. The system includes feed and backwash pumps, media filter, dechlorination, antiscalant, and post-chlorination dosing systems. The feed water is coming from a brackish well, and the capacity of this system is 173,000 GPD. This system is for industrial use.

Water Concern Total dissolved solids (TDS) is the most commonly used measure of water quality. High accounts of TDS refer to elevated amounts of contaminants present usually in parts per million (PPM). Hotels utilize water in almost every part of their facility. From kitchens to pools to showers, water quality is integral to offering an exceptional customer experience. Elevated TDS levels in water can result in a variety of negative effects like taste and odor. Turbidity is another common issue that occurs with elevated TDS. In general, the term TDS is used to account for all the dissolved solids which can include specific harmful elements as well. Calcium and magnesium are two elements that are often present in water and they contribute to the hardness levels. Reducing the TDS would reduce the accounts of these elements and prevent the damage of any surfaces in contact with the water. Therefore, a purification system is necessary to provide for this industry’s water source to supply the multiple applications with almost zero TDS.

Applied Solution: This industrial reverse osmosis machine was recommended for a hotel in Oman to reduce TDS. The source of the water was municipal water of around 500 PPM TDS. For this particular customer we solely provided the reverse osmosis machine without pre/post treatment. The reverse osmosis machine was built to produce the capacity of 130,000 gallons per day and reduce the TDS level of 500 PPM TDS to less than 20 PPM. This will ensure the quality of water supplied to the hotel is completely purified and will only complement the various applications necessary.

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

The system design was based on high rejection TFC Spiral wound low fouling membranes. The Water Maker produced 188,000 GPD at a maximum 45,000 PPM feed water TDS while the Brackish RO Unit produced 130,000 GPD with a 100 ppm feed water TDS. From its initial start-up, the units have been running smoothly with minimal trouble-shooting. As a result, the military base has a reliable and steady supply of drinkable water at a cost far less than shipping water to the site.

Water Challenges: Military bases in Oman, such as the “Ministry Of Defense” requires a large supply of freshwater for the purposes of providing drinking water to soldiers and equipment that require the use of water. Since Oman is a country that does not possess sufficient freshwater supplies, the country depends on taking water from the sea and converting it into fresh, usable water. Seawater reverse osmosis systems are the treatment solutions utilized to achieve the purification process that effectively eliminates all unwanted impurities from the water, such as high levels of salt and minerals, into ultra pure water.

Applied Solution: Pure Aqua successfully manufactured and supplied a Double Pass Industrial Water Maker followed by an Industrial Brackish Water RO Unit to produce drinking water with Boron content less than 1ppm for a military base at the Oman Ministry of Defense. The Industrial Water Maker was selected from our SWI Series, while the Industrial Brackish RO Unit was selected from our RO-400 Series. These units came complete with an advanced PLC, cleaning and flushing systems, coagulant, pre & post de-chlorination, and antiscalant dosing systems. Feed water to the system is processed water and seawater well.

Seawater reverse osmosis systems are built for highly inconsumable water sources like the sea, removing enormous amounts of salt and other contaminants from them. Denying salts, particulates, and other contaminants from carrying on, water molecules are only permitted through the tiny pores of the membrane. Fresh, purified water emerges on the permeate side and is ready to be collected while salt, particulates, and other contaminants are discharged into a drain from the concentrate side.

Water Concern: Public facilities like malls or entertainment centers require water for general human use. These applications range from drinking fountains to toilet water. Therefore, a systemic water filtration system would best suit the requirements for all the applications. Supplying water from a well source usually includes an abundance of elevated parameters. The concern for this customer was reducing the TDS levels to accommodate the intended applications of the facility. This customer had a well water supply that contained 8,000 PPM TDS and was looking to produce 600,000 GPD.

Applied Solution: This industrial brackish RO equipment was recommended and constructed for a public mall facility in Kuwait. The capacity of this RO equipment was 600,000 GPD and the product is intended to be the main supply of water for the facility. This system includes the necessary pre-treatment and post-treatment units that keep the RO equipment functioning efficiently without any problems. Part of this pre-treatment is duplex multimedia filter to reduce turbidity and suspended solids. The pre-treated water continues on to a 5-micron cartridge filter to further reduce any leftover suspended solids and is injected with sodium metabisulfite along with antiscalant for chlorine reduction prior to reaching the RO membranes. Then, the water is pressurized by high-pressure pumps through the RO membranes that will raise the pressure to 300 PSI. The water exiting the system results in a product and reject stream.
