Abstract

proposal for energy recovery device

The main objective of this research is to conceptualize, design and study a system that will solve the existing problem encountered in ELITE Power Plant.  The Reverse Osmosis Plant, basically resulted to a high power consumption particularly in a high pressure pump motor of the system. Reduce the load on the high pressure pump motor which caused high power consumption.

In order to lessen the problem on high consumption as well as repair and maintenance, the use of “ENERGY RECOVERY DEVICE” is suggested.  In which it is designed based on the machine components potential requirements and specifications.

Reverse Osmosis System us to take seawater, filter and treat seawater for domestic use, service water and to supply the deminiralizers at the water treatment plant.

Osmosis is the naturally occurring diffusion of fluids through a semipermeable membrane in the attempt to equalize different concentrations of dissolved solids.  The Reverse Osmosis System takes this natural occurrence, reverses it by applying pressure on one side of the membrane and separates the two concentrations, in this case, fresh water from salt water.

Water is pumped from the sea, sent through a series of filters, then pressurized through membranes where salt and fresh water separates, chemically treated, and forwarded on storage tanks.
While, Energy Recovery Device, connected to the opposite end of the high pressure pump motor shaft.  The purpose of the ERD is to reduce the load on the high pressure pump motor.  This is accomplished by utilizing the energy contained in the high pressure brine before it goes to the drain.

During the practicum at the ELITE Power Plant, the researcher was assigned at the Reverse Osmosis Plant where the project is located.

Together with the Plant Technician, the researcher inspected the sites where the operation for Reverse Osmosis Plant is on going.  The activities were purely operation and monitoring such as providing the data for Reverse Osmosis Plant.

Upon evaluation of the plant, one of the problems in the system is high energy consumption of the high pressure pump.  The researcher determined that application of Energy Recovery Device is recommended.
The company will be benefited in this study, of which the maintenance of the different motor equipment used in their operation will lessen as well as students who will go further studies related to this.
