A high-pressure pump is utilized as an integral part in the Reverse Osmosis(RO) technique to constantly convey/deliver pressure to the feeder straits/channels . The supplied stream is divided/split symmetrically into ‘brackish/brine(or reject) stream’ , which has a high concentration of dissolved salts , & ‘permeate’ stream , which has a low concentration of dissolved salts . So now we talk use of high-pressure pump in ro plant of a water treatment.
Operating principle of High-Pressure Pumps
Systems of Reverse Osmosis(RO) operates on the principle , increasing the pressure/force on the salt-side of the Reverse Osmosis(RO) & forcing the water past the semi-permeable RO membrane , leaving behind nearly all(approx. 95 – 99%) of the dissolved salts in the reject stream .
Water treatment plants is the best manufacturer of water treatment plants.
Generally, High pressure pumps in commercial RO plants are susceptible/vulnerable to a various kinds of issues/problems , including :
- Water-seeping(leaks) from the pump-head causing severe damage to the pump.
- Unusual sounds create abnormal noises .
- Boosting-pressure becomes poor.
- Seals on the driving piston are severely worn , resulting in air -leakage .
- A reversing valve becomes dirty & sometimes fails to move normally .
And because of above mentioned problems these high-pressure pumps are subjected to fail, which occurs due to the following reasons :
- Harsh coarse wear & tear following the presence of solids in the water.
- Various Chemical Reactions within the elements , oily & greasy matter & particles present inside it.
- Scaling & Fouling
- Cavitations
Pump failure is costly in terms of interruptions , delays , repairs , & damages . Understanding the reasons for failure can helps in selecting pumping equipments , decreasing the chance of failure .
Determine if the high- pressure pump on the equipment has failed , as well as whether the water-treatment accessories , & consumables are in excellent operating condition.
If neither waste-water nor clean water is discharged , or if only a little amount of wastewater is discharged, the pre-filter may get jammed .
Detailed Elaboration of the Reasons/causes for the High-Pressure Pump Failures in the RO plant :
Abrasive wear is caused by solids in the water :
Because mineral water-pump stations have greater levels of filtration, this type of wear is often reduced , albeit pebbles or other debris may become caught inside the pump & cause issues .
This material is significantly more prevalent in raw water pump stations . Gravel occasionally makes its way into the completed water system , most often as a result of a construction project .
Different Reactions occurring Chemically :
Corrosion & impeller deterioration are caused by chemical interactions between the solution & the impeller material. Water variables such as the chemicals used for treatment, cavitation, & water temperature may exacerbate these issues.
The corrosivity of the water in the pump impeller may be altered by how it is chlorinated by water operators.
Failure because of Cavitations developing :
Cavitation, which causes pitting & cracks in the impeller, volutes, & casing, can weaken the metal , increase flow resistance , & diminish pumping efficiency.
The service life of the shaft & motor may be reduced as a result of the shock loads induced by cavitation . Cavitation & the difficulties it causes can severely diminish a pump’s life, reducing it in half or more in extreme cases.
Fouling due to outside particles accumulating
Particulate matter adheres to the inside surfaces of a pump, most commonly in distribution lines linked to the intake or outflow, resulting in fouling. As a result, pumping efficiency & flow capacity are lowered, & the system may eventually fail.
This is an in-escapable problem, & it is especially prevalent in situations where the pumped fluid contains particles. On the other hand, many cleaning procedures may be used to keep the pump in excellent operating condition & boost its efficiency & capacity.
