Applications of High-Pressure Pump in Various RO Systems
Reverse osmosis is a filtration process used to separate the dissolved impurities and waste matter in the water to provide pure water. High-pressure pumps are the heart of any reverse osmosis system. To understand the role of high-pressure pumps in reverse osmosis, one must understand what a high-pressure pump is and where in the process of reverse osmosis it is used.
What is a High-pressure Pump?
A high-pressure pump is a hydrostatic pump, and it is a positive transfer pump that does not work in closed systems. It is used for dispensing gas and fluids at a very high thrust.
A reverse osmosis system works by forcing water through a semi-permeable membrane at a pressure that is high enough to overcome the natural osmotic pressure. To achieve this force, the system uses a high-pressure pump. The RO membrane acts as a porous sheet barrier with pores that only let pure water through and reject larger molecules such as the dissolved salts, minerals, bacteria and other particles.
Reverse osmosis is a pressure-riven process. Typically, the RO units operate on low pressure, and the water supply will be very slow. Low inlet pressure makes the reverse osmosis unit reject more water, producing less clean water and thus slowing the process. This is why a high-pressure pump is used in reverse osmosis systems.
Applications of High-Pressure Pumps in Reverse Osmosis Systems
The high-pressure capabilities are the most vital feature of a high-pressure pump. The amount of pressure required depends on the salt concentration of the feed water. So, the more concentrated the water is, the more pressure is required to overcome the osmotic pressure. The various industries in which high-pressure pumps are used are:
· Industrial wastewater treatment: Water is a key component in many industries. Industrial processes surrounding manufacturing and the cooling of plants and machinery use water. This water, after use, ends up with many chemicals, oils and other residues- also called wastewater.
Using reverse osmosis, the often-harmful waste in the water can be separated, resulting in clean water that is safe for disposal in the environment. This clean water can also be reused, helping the company save money on water bills.
Depending on the nature of the wastewater, the industry may use any of the various high-pressure pumps in India. For instance, the recycling industry may use harsh chemicals to treat metals. Since this wastewater is extremely toxic, the high-pressure pump needs to be able to deal with such corrosive fluids as these can affect its material of construction.
· Desalination Industries: The high-pressure pump is widely used in the desalination industries. A high-pressure pump is the heart of any desalinator. Desalination refers to the removal of salts, minerals and ions from seawater to convert it into fresh water. This is then used for drinking, washing and other purposes.
Modern vessels are installed with a desalination reverse osmosis system that helps produce fresh water on board by using the water most easily accessible to them. This saves the vessel owner the costs of purchasing water from suppliers at each port. High-pressure pumps that are used for desalination are made of materials that are resistant to corrosive salt content.
The pressure of the high-pressure pump depends on the salt content level in the desalinated water. Thus, high-pressure pump manufacturers in India recommend using pumps with higher pressure levels than the desalination pumps used in brackish waters.
· Food and Beverage Industry: Reverse osmosis is used in various food production sectors. Apart from wastewater treatment, reverse osmosis is also used in the process of food production. For example, reverse osmosis is used in the dairy industry to separate whey from water and leave behind concentrated whey protein.
High-pressure pump manufacturers in India recommend using food-grade high-pressure pumps. The pressure of these pumps depends on the viscosity of the fluid being treated.
Choosing the Best High-Pressure Pump for Your Industry
In the highly concentrated pump industry, choosing the right high-pressure pump manufacturer can be difficult. Your best bet is to head online to find a trustworthy high-pressure pump provider. A good high-pressure pump manufacturer will help choose a suitable pump by keeping in mind the reason it is needed, running costs and other specifications.
