Large Reverse Osmosis System RO-600

Quality Systems at an exceptional value
Product Description

Pure Aqua manufactures large reverse osmosis systems from the RO-600 series which are designed to eliminate high concentrations of contaminants in water. These contaminants range from total dissolved solids (TDS), salt, bacteria, proteins, metals, organic substances, dyes, and constituents that contain a molecular weight higher than 150-250 Daltons.

Pure Aqua's comprehensive line of conventional and completely customizable brackish reverse osmosis systems are also engineered through cutting-edge 3D computer modeling and process design technology for precise and tailor-made solutions. 

The parts that make up this large RO system include spiral membrane elements constructed from one or multiple membrane envelopes that are engrossed around a perforated central tube. The permeate flow is sent through layers of membranes into the envelope and makes its way to the central tube where it sits. The membrane layers are displayed in the picture to the right.

While smaller systems are designed for most commercial businesses and other lesser-scale applications, our large reverse osmosis system is produced to perfectly handle manufacturing and healthcare facilities of great proportions. Regardless of what type of system that you might require, a large reverse osmosis system is tailor-made to produce you the cleanest water for consumption or other use. 

The Filtration Phases of Large Reverse Osmosis Systems

A large reverse osmosis system generally consists of distinct filtration and carbon constituents. Carbon filters work in conjunction with a large RO system to eradicate chlorine, chloramines, disinfectants, VOCs, and pesticides that enhance the taste and odor of water. Commercial water softeners also help by softening water that prevents membrane fouling. This multi-filtration method ensures an extremely purified solution for the production of highly pure water.

Modern large reverse osmosis systems also incorporate pre-filters to eliminate sand, particulate matter, rust, and turbidity that are capable of causing damage to the membranes. It is crucial that you the steps to safeguard your membranes from these potential threats so they can do their work. RO membranes are very efficient in removing a wide range of salt, dissolved solids, lead, heavy metals, organic & inorganic substances, microorganisms. These membranes take in water forced through the system by a high-pressure pump that drives water flow into the pores of the semi-permeable membranes.

There is a storage tank and other water purification optionals that can be used such as uv sterilizers that kill biological organisms, water deionizer systems used as post-filtration to ensure ultra-pure water.

The Benefits of a Large Reverse Osmosis System

  • Enhanced flavor, smell and appearance 
  • Purifying procedure with high quality 
  • Takes out contaminants 
  • Conductivity/total dissolved solids decrease  
  • Brings down hardness in water  
  • Reduced price for high value   
  • Mitigates alkalinity

Other water treatment systems can minimize contamination and may take significant initiative to operate over time. These units also include additional pollution risks can arise if something fails with that specific system. Your water, however, remains fresher spotless through the use of reverse osmosis.

There are various utilizations that a large reverse osmosis system is suitable to handle in both industrial and commercial industries. Although everybody needs their water to be healthy water supply and nice drinking water, companies require clean water to make the most of their business operations. Food suppliers, health facilities, pharmaceutical companies and industrial cooling towers could all benefit from the reliably clean and fresh water provided by the method of reverse osmosis.

Large RO systems are capable of eliminating other impurities not known by many users such as flouride, arsenic, radium, nitrate, sulfate, potassium, and more. Once these substances are taken out by the membranes, they are discharged and flushed away.

Maintenance is made to be simple and extremely cost-effective. Users are only required to clean and change the RO membranes and filters in use on an occassional basis, including sanitizing the system itself. Our RO-600 large RO system provides a user-friendly option to guarantee pristine water purification.
