Importance of water pumps in RO plants
In our previous article, we mentioned the importance of choosing the right valve for the construction and design of water treatment plants. In this article, we discuss the importance of water pumps. Their different types, and how to choose the size or capacity of the pump. We trust in Carewater that the secret to excellence and continuity of quality is by paying attention to all details.
The role of water pumps
The water pushes the permeate to the point of the end of use. The selection is made on the basis of the overall distance and the desired goal. This pump should be selected from stainless steel to prevent any contamination of the permeate water.
It is important for the system to ensure that the pump matches the proper number and size of membranes. Typically, the higher the horsepower on the inside of the pump, the better the permeate rejection and recovery rates.
Types of water pumps used in waterworks
Several types of solar pumps depend on how they are classified. But primarily there are four types of water pumps:
First submersible pumps
As the name implies, the submersible pump is located deep below ground level and remains submerged under water.
The suction head of the submersible pump exceeds 10 meters in depth, these pumps are installed by drilling a backhoe, which increases the cost of installation and maintenance.
Second, surface pumps
Surface pumps remain out of the water and in the open, they are installed where the water table is at a depth of 10 meters, since they need to be on the surface, this particular type of pump used in different waterworks is the easiest to install and maintain, however, They are not suitable for deep groundwater.
Third, DC pumps
This pump works on a direct current motor, and therefore there is no need for a battery or inverter in this type of pump type used in waterworks.
Fourth, alternating current (AC) pumps
The motor of this pump runs on alternating current, which means that the direct current produced by the solar panels, is converted into alternating current using the inverter, converting from DC to AC to energy loss from generation and consumption.
How to choose the suitable water pumps
There are some calculations that must be done accurately. To ensure that the proper water pump volume is calculated. so always assigning this task to a technician who is an expert in these calculations saves you the trouble of going through many problems.
Among the most important facts to ensure that the appropriate water pumps are selected, the following facts must be taken care of:
- The volume of water to be produced in the water treatment plant.
- Pump pressure It is determined based on the depth of placement of the pump in the well.
- The vertical distance between the surface of the earth and the depth of the water in the well. Every 10 meters = 1 bar.
- The horizontal distance between the well outlet and the water treatment plant every 100 meters = 1 bar.
