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.

    Great designed RO system for nitrate removal from water, and we loved that your engineers designed it with low energy membranes
