4 Definitions

Anthracite: A granular hard coal used as a filtration medium in multi-media filters.

Backwash: The procedure used to flush deposited solids out of the granular filter at the

end of the filter run. This normally involves feeding clean water in the base of the

granular bed and washing it in an upward direction.

Design Engineer: The Engineering Company responsible for specifying the design

requirements for ROS on the drawing sheet, in accordance with the requirements of this

specification.

Page 4 of 18

Filter Medium: The term filter "media" is in common use to describe granular filtering

materials. Grammatically, it is plural and should apply to the bulk material to be

installed in several filters. (A single filter has a filter medium). To avoid ambiguity the

term "filtering material" used in the American Water Works Association (AWWA

B100) specification is preferred.

Packing layer: A granular material, coarser than the working filtering material, which

is not intended to capture suspended solids and neither is it intended to move or be

fluidized during filter backwash.

Polyelectrolyte: An organic chemical compound with many repeated structural units

produced by uniting many primary units, called monomers. It is added to the water to

agglomerate particles into larger groupings called flocs, which then settle by gravity.

Pretreatment: All the unit operations upstream of the reverse osmosis (RO) system

that have purpose to eliminate or minimize the fouling potential of the RO feed water.

Saudi Aramco Inspector: The person or company authorized by the Saudi Aramco

Inspection Department to inspect ROS to the requirements of this specification.

Silt Density Index (SDI): A measurement of the rate of plugging of a 0.45 micron

Millipore filter at 207 kPa (30 psig) applied pressure.

5 General Requirements

5.1 The vendor shall be fully responsible for the performance of the system and for

each component in the system for a minimum of one year.

5.2 The skid shall support the total system for transportation to the field and shall

require only setting on a prepared deck or foundation. After making field

connections to prepared terminal points it should be ready for commissioning.

5.3 Each skid shall support complete subsystems (e.g., pretreatment system,

chemical cleaning system), requiring only skid-to-skid and terminal point

connections in the field.

5.4 The skid shall be fully automatic, including backwashing of all systems and

chemical injection. However, the membrane cleaning system shall be designed

for manual and automatic operation.

5.5 The vendor shall provide all the special tools for assembly, disassembly, and

unit maintenance, along with complete instructions for their use.

5.6 Provisions shall be made, where applicable, to prevent organic growth and

dehydration of membranes during shutdown.

6 Performance Guarantees

6.1 The water quality produced shall comply with the Saudi Aramco Sanitary Code

(SASC-S-17) relating to quality of water intended for human consumption.

6.2 The vendor shall guarantee that the membrane, when operated in accordance

with the instruction manual, will produce the specified product water flow rate

at the specified water quality for a minimum of three years from the date of

commissioning.

6.3 The vendor shall propose pretreatment chemicals (scale inhibitor, coagulant,

flocculent) approved by the membrane manufacturer and Consulting Services

Department of Saudi Aramco. These chemicals shall comply with applicable

health regulations and the vendor shall state the recommended and guaranteed

maximum dosage.

7 Design

The design of the RO skid shall be based on an accurate raw water analysis provided by

the proponent and checked by the vendor. This analysis should include all the

parameters shown in the technical data sheet "water analysis" in the Appendix.

Analyses for suspended solids (SS), pH, alkalinity and gases should be performed at the

point of sampling or alternatively pressurized samples should be taken if analyses are to

be carried out in the laboratory. The membrane design configuration and performance

should be determined on the basis of computer projection programs. These projections

should be within the membrane manufacturers' design guidelines. Additionally,

antiscalant projections should be carried out to determine the required dosage of

antiscalant for scaling prevention. Copies of the output of these programs should be

made available for review by CSD in order to check that the optimum membrane

configuration is being used as well as the optimum antiscalant dosage.

The RO Skid Unit shall contain, but not necessarily be limited to, the following

equipment:

chemical conditioning. The system shall ensure that the Silt Density Index

(SDI) meets the membrane manufacturer's SDI requirements.

anticipated media expansion level) to provide additional safeguard

against media losses during backwash. The system shall provide

adequate flow and distribution to uniformly expand the filter bed

during backwashing, and to uniformly collect the filtered water

during the filter cycle.
