High-Flow Reverse Osmosis System - Commercial - Crystal Quest Water Filters

Reverse Osmosis (RO) Systems 

Thanks to our flexibility and expertise, we can engineer our RO systems to meet any application requirements. Generally, RO systems are categorized into three main types: traditional, brackish, and desalination. 

Traditional systems typically operate with a feed pressure of 200 to 400 psi. This requires minimal energy, as only enough pressure is needed to push the feed water through the membranes and overcome the osmotic pressure. 

Brackish systems operate at pressures above 400 psi, using more energy because of the need for a higher-pressure pump. Brackish water has a higher concentration of dissolved solids compared to the water processed in traditional RO systems. 

Desalination systems function at pressures of 800 to 1200 psi. These systems require specialized high-pressure pumps made from durable alloys to withstand the intense pressure. Given the high energy demand needed to counteract the osmotic pressure, energy recovery devices are commonly used in these setups.

Industrial Water Filtration Units

Filtration is a crucial element of any water treatment system, and we design filtration units to handle all kinds of water types. A common filtration process targets TSS, iron, and manganese, using media such as sand, multi-media, Greensand, and Birm. When designing filtration systems, there are several factors that we consider such as: 

  • Specific elements to be removed 
  • Concentration levels of these elements 
  • Flow rate 
  • Bed surface velocity 
  • Required retention time 
  • pH levels 

Another frequently used filtration method is carbon filtration, which is effective for removing chlorine, benzene, radon, solvents, trihalomethane compounds, and volatile organic compounds (VOCs). Specialized carbon options are also available to eliminate many additional compounds from water. 

Industrial Water Softening 

High levels of calcium and magnesium in water can disrupt equipment function, reducing efficiency, driving up energy costs, and even leading to equipment failure. To address this, many facilities use water softeners for boiler feed, cooling towers, and entire water supplies. 

When designing water softeners for boiler feed, key considerations we include are: boiler horsepower, condensate return, operating pressure, and water hardness.

Boiler feed systems typically use alternating water softeners to ensure a continuous supply of softened water. Since boiler efficiency depends more on capacity than flow rate, capacity is a critical factor in system design. Higher operating pressures require stricter water quality standards. 

Water softeners are also commonly used for cooling towers. When designing a water softener for cooling towers its vital to consider: 

  • Water hardness  
  • Number of cycles before blowdown 
  • Size of the feed line to the tower 
  • Tonnage

Flow rate and capacity are essential in designing a softening system for cooling towers, as a thorough understanding of daily water usage and flow rate requirements is crucial. 

For many plants, using water softeners for the entire facility’s water supply is essential. High hardness levels make water softening the most cost-effective solution to protect the plant from scaling, which can lead to operational issues and costly damage.

Industrial Deionization (DI) 

Deionization systems treat incoming water by utilizing cation and anion resins, or a mixed-bed resin. The result is a reduction in the total dissolved solids (TDS) in the water.

Unlike reverse osmosis systems, which rely on electricity to power feed pumps, deionization systems regenerate using acid and caustic chemicals. When applied effectively, deionization (DI) can produce highly pure water with great efficiency. A Dual Bed DI system typically achieves a water quality of around 200k, while a Mixed Bed DI system can reach up to 18 megaohms. 

Key factors to consider when sizing a DI system include: 

  • TDS levels 
  • Required effluent water quality 
  • Daily capacity needs 
  • Operating costs (volume of acid and caustic chemicals required) 
  • Flow rates

Dealkalizer

systems are commonly used in boiler water treatment but can be applied in other contexts as well. When designing a dealkalizer system, it’s essential to assess the full water treatment requirements, including desired water quality, the quality of the incoming supply, required flow rate, and daily capacity needs. 

The two primary types of dealkalizer systems are chloride cycle dealkalizers and acid-regenerated dealkalizers. Each system has its unique advantages and is chosen based on specific customer requirements. 

Arsenic Removal Systems

Arsenic removal can be achieved through various methods. Reverse osmosis is highly effective, though other treatment options are also available. Selective media, for example, targets arsenic specifically and doesn’t require regeneration. System design involves calculating the media's life expectancy, determined by water volume and arsenic levels. When the media is exhausted, it needs to be replaced. Arsenic exists in two forms—Arsenic III and Arsenic V—with the latter being easier to remove, so a full water analysis is necessary before system design. The EPA’s maximum contaminant level (MCL) for arsenic is 0.010 mg/L or 10 ppb.

Radium Removal Systems  

Radium removal can be accomplished with water softeners, reverse osmosis, or selective radium resins. Selective radium resins are advantageous as they don’t require regeneration. System design calculations help determine the media’s expected lifespan based on water volume and radium levels. Once exhausted, the media needs to be replaced. Radium has two forms—Radium 226 and Radium 228—with an EPA-set maximum contaminant level (MCL) of 5 pCi/L. 

Uranium Removal Systems  

Uranium removal systems use specialized resin to capture uranium without requiring regeneration. The resin’s capacity depends on water volume and uranium concentration, and, once saturated, it must be disposed of at a nuclear waste facility. Due to the high concentration of uranium in the used media, specialized equipment and strict security measures are required during removal to prevent unauthorized access. The appropriate federal agencies should be involved throughout this process.

Fracking Water Treatment 

What is Fracking? It is the process used after drilling a well and inserting a steel casing into the wellbore. The casing is perforated in specific target zones that contain oil or gas, allowing the injected fracturing fluid to flow through these perforations into the desired areas. When the formation can no longer absorb the fluid as quickly as it’s injected, the increasing pressure causes it to crack or fracture. Once fractures are formed, fluid injection stops, and the fracturing fluid begins to flow back to the surface. Materials called proppants—typically sand or ceramic beads—are left within the formation to keep these fractures open. 

Studies indicate that between 20-85% of fracking fluids may remain underground. The fracturing fluids that return to the surface, known as flowback, are generally stored in open pits or tanks at the well site until disposal. 

Crystal Quest has extensive expertise in treating water used in fracking, previously thought to be untreatable. In the past, fracking wastewater was typically disposed of via deep well injection; however, many states no longer permit this method. As the industry has expanded across the U.S., especially with heavy development in areas like the Marcellus Shale, a sustainable disposal plan for frac water remains a challenge. Often, this water is transported out of state or to points of use (POUs) unprepared to properly treat or assess the toxicity, creating potential long-term environmental issues, only recognized once contamination affects streams, landfills, and drinking water sources. 

How do we treat water with high levels of TDS, uranium, radium, silica, chlorides, TOC, iron, free oil, and other compounds?  

Achieving this requires thorough research and design to develop a reliable treatment method. We have conducted the necessary work and can provide a treatment program that integrates with your existing process or offers a full treatment plant solution. 

  A comprehensive treatment plant may involve 18 to 25 stages to achieve potable water quality, depending on the complexity of the wastewater. We can design plants with capacities ranging from 50,000 gallons per day up to 10 million gallons per day.
