Tap & Brackish Water RO


Tap Water

Reverse Osmosis systems can operate with Tap ot Brackish Well Water, for applications such as hydroponics, coffee shops, restaurants, convenience stores, micro breweries, supermarket produce and food preparation operations, misting and humidification systems, car wash facilities, and many other businesses that must have consistent high quality water for their daily operations.

Definitions:

Reverse osmosis (RO): is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied.


In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2–17 bar (30–250 psi) for fresh and brackish water, and 40–70 bar (600–1000 psi) for seawater, which has The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2–17 bar (30–250 psi) for fresh and brackish water, and 40–70 bar (600–1000 psi) for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome.


This process is best known for its use in desalination (removing the salt from sea water to get fresh water), but it has also been used to purify fresh water for medical, industrial and domestic applications since the early 1970s. In reverse osmosis, in a similar setup as that in osmosis, pressure is applied to the compartment with high concentration. In this case, there are two forces influencing the movement of water: the pressure caused by the difference in solute concentration between the two compartments (the osmotic pressure) and the externally applied pressure.

Brackish reverse osmosis systems tend to operate over 400 psi and require more energy as a higher pressure pump is necessary. Brackish water has higher total dissolved solids than water that is fed through a traditional reverse osmosis system. The feed TDS levels are typically 1,000 ppm to 5,000 ppm. Brackish reverse osmosis systems have a configuration that includes a pre-filter, pvc header piping, plc controller, and fiberglass pressure vessels for the membrane housings. Options include stainless steel pressure vessels, stainless steel header piping, plc controller with remote monitoring, controller with touch panel display, design modifications for higher recover rates, and other equipment depending on your application.

Brackish Water

Brackish water contains relatively high levels of dissolved salts and minerals. Depending on the location, it can range from 1,000 to 10,000ppm and high brackish is 10,000 to 15,000ppm. We offer solutions to all your brackish water problems.

Brackish water desalination gained wide acceptance during the mid-eighties when RO membrane manufacturers developed robust membranes that could withstand cleaning, biofouling and high operating pressure over many years.

Our water purification systems are used across many sectors worldwide, including farms, Agribusiness, hotels and resorts, dairy and food processing industries, commercial and civic water supply.

Our containerised water treatment systems offer reliability and robustness to meet the operational requirements of cogeneration plants, municipalities, the shipbuilding industry, electronic plants, resorts, and others.

BRACKISH WATER DESALINATION

Definitions:

In general, ground or surface water with an increased salt content is referred to as brackish water. With the aid of desalination systems, this can be processed accordingly so it can be used as drinking water or process water for industry.

Design:

The design and construction of brackish water desalination systems primarily depend on the salinity of the available water, the substances contained in the water, and the parameters required for product water. It is therefore necessary to plan and design the systems on an individual basis, which is often associated with high costs. Standard systems offered at suitable prices often only represent a compromise, as these frequently do not sufficiently meet the individual needs of the customer.
