Large Reverse Osmosis System from NEWater

Our Large Reverse Osmosis Systems work with the help of a multi-step process, each part of which helps ensure fresh and healthy consumables. It starts with determining whether large debris has to be removed, this is done by using settling tanks and membranes with larger bore sizes.

The water is pressurized using pumps and is pushed through partially permeable membranes that retain the impurities and allow only the water to pass through. The water may then be treated to remove hardness, by reducing its ion content using cationic and anionic resins. This allows water to be ideal for both domestic and commercial uses.

NEWater’s large scale reverse osmosis system may also make use of post-purification treatments such as UV light, and removal of microbial pathogens that may cause disease! Send over any questions that you may have, we are looking forward to being of service!

The Ultimate FAQ Guide for Large Reverse Osmosis Systems.

Inaccessibility to freshwater reservoirs has driven the current demographic into exploiting other water sources such as groundwater, seawater, and brackish water. Reverse osmosis systems have facilitated the conversion of saline and contaminated water into high-grade product water by significantly lowering the TDS levels.

Countries in arid and semi-arid regions such as Northern Africa and the Middle East harbor most of the world’s largest reverse osmosis plants. Below we examine large RO systems and their role in remedying global water scarcity.

➣What is a Large Reverse Osmosis System?

A large reverse osmosis system is simply a high-capacity water treatment plant utilizing high-pressure pumps and RO membranes for heavy and continuous production of product water. Large RO units are rapidly proliferating seeing that municipalities and enormous industries are incorporating them into their water treatment projects.

Typical large RO systems generate 200,000 to 900,000 gallons of water per day. The primary attribute of large reverse osmosis plants is their high flow rate and high-pressure pumps. These systems are specialized to treat distinct sources of feed water with seawater and brackish water dominantly prevalently utilized.

➣Where are Large Reverse Osmosis Systems Mainly Applied?

Generally, reverse osmosis systems provide valid and viable water solutions to diverse sectors. In coastal, arid, and semi-arid regions governments through their respective municipalities, exploit large RO systems to ensure their residents access fresh potable water.

Similarly, large industries with a humongous demand for product water, utilize large RO units to reinforce their freshwater supply. Underneath, we unravel renowned sectors making use of large RO systems across the world.

● Water bottling and beverage production.
● Municipal water treatment.
● Power plants.
● Refineries.
● Boiler feedwater.

➣How Do Large Reverse Osmosis Systems Operate?

Large volume reverse osmosis systems and small RO units have their differences but essentially, they adhere to the same working principle. By sharing a similar process, they are able to generate high-grade product water for diverse applications. A high-pressure pump is obligatory in large reverse osmosis systems. It breeds pressure necessitated to reverse the normal osmotic flow thereby initiating the reverse osmosis process.

Primarily, reverse osmosis systems kick-start their water treatment process in a pretreatment unit. Often, this involves the utilization of chemical dosing and pre-filtration. Sediment filters make certain that sand, debris, colloids, and conventionally large particulates are eliminated from the water to avert membrane fouling. Chemical dosing is deployed to nullify the threat of scaling and equipment corrosion.

Subsequently, the water is forcefully pumped through the perforated RO water membranes. Unlike regular osmosis processes, the water flows from the region of high concentration to a less concentrated one. The membrane pores selectively alienate dissolved solids, microorganisms, chemicals, and minerals from water, ultimately generating permeate and brine.

Based on the projected quality of the permeate, a post-treatment process is enforced. Carbon filters are regularly utilized to eradicate chlorine, bad smells, and tastes while Electrodeionization is utilized to get rid of C02.

➣What are the Advantages of Large Capacity Reverse Osmosis Systems?

Primarily, large reverse osmosis systems have proven their value as comprehensive remedies to the global water scarcity menace. They generate high-quality product water suitable for distinct industrial, commercial, and residential applications.

➣What are the Distinct Types of Large Scale Reverse Osmosis Systems?

There are numerous types of large RO systems differentiated by their suitability to specific applications. NEWater provides a comprehensive range of large reverse osmosis in standard and customized versions. The following is a list of our distinct large reverse osmosis plants.

Large seawater RO systems.

Seawater desalination using reverse osmosis systems is presently a common occurrence. Seawater RO plants are characteristically endowed with high TDS levels (approximately 35,000 ppm). This ensures they effectively desalinate seawater for years without depreciating in performance. They are available in containerized, modular, and skid-mounted designs.

Large brackish water RO systems.

Brackish water RO plants are particularly designed to desalinate slightly saline water. These systems support TDS levels ranging from 1000ppm to 15,000ppm. Large brackish water RO systems can be skid-mounted, modular, or containerized. They are more energy-efficient and can desalinate huge volumes of brackish water continually.

Other large reverse osmosis systems include:

• Well water RO systems.
• Wastewater RO systems.
• Containerized and Skid-mounted large RO systems.

➣How Much Does a Large Reverse Osmosis System?

Compared to small-scale reverse osmosis, the production of product water using large RO systems is relatively economical. Essentially, the total cost of a large reverse osmosis plant is achieved by adding up the cost of equipment, installation, labor, power consumption, upkeep, and value depreciation. To illustrate the cumulative cost of a large RO system, we are going to disintegrate the investment and operational expenses of a 10,000 tons per day seawater RO plant.

The power consumed when desalinating a ton of seawater costs 2.25 yuan while salaries and wages for the labor force are approximately 0.2 yuan. The reverse osmosis membranes necessitate changing often after three years, totaling 0.05 yuan per ton of water. The depreciation of RO equipment is estimated to be 0.12 yuan per ton. This adds up to 4.54 yuan as the cumulative cost of generating a ton of water using a large reverse osmosis unit.
