WaterThe Essential Fluid

For:Municipal, residential, commercial,

institutional, industrial

Focus on industrial:

Chemical, petrochemical, refining, pulp and

paper, power, food and beverage,

pharmaceutical, and semiconductormanufacturing

Water can be used as a utility, a reactant, or a

raw material

Water Use - Chemical/Petrochemical

Heat transfer mediumcondensers, heat

exchangers, cooling towers, etc.

Raw material

diluentSolventwashing product/equipment

Reactant(Ex.) producing high-purity

hydrogen in a steam reformer

PRIMARY QUALITY CONSIDERATION:

CORROSION RESISTANCE

Water UseRefining

Water is used in almost every refining process from

alkylation through visbreaking

As much as 77,000 gallons/100 barrels of crudePrimary heat transfer medium


CORROSION CONTROL

Water UsePulp and Paper

Water flows within every line in the utilities, pulping

operations, and on the paper making machine

Water usage7,920 gallons/ton of pulp mechanical pulping

39,600 gallons/ton of pulp chemical pulping

Applications

Cooking pulp, drying paper, cooling


CORROSION, SCALE, AND BIOLOGICAL CONTROL




Water UsePower Generation

Treated water is the process fluid in a power plant

Conductivitymeasured at all key points

pH

measurement focused in the steam areaDOmeasured around the deaerator

Usage depends upon the size and design of the

power plant


CORROSION AND SCALE CONTROL




Water UseFood and Beverage

Food and beverage processing are sanitary

industries

Typical annual US consumptionBeer6.2 billion gallons

Carbonated soft drinks15.2 billion gallons

Water6.3 billion gallons

Water is the primary raw material


CHEMICAL/ BIOLOGICAL CONTAMINATION




Water Use - Pharmaceutical

Water is the most widely used raw material in the

pharmaceutical industry

Pharmaceutical grade watersPotable, purified, WFI, reageant

Utility grade waters

Plant and clean steam, chilled water


APPLICATION SPECIFIC CHEMICAL, MICROBIAL,

AND PHYSICAL ATTRIBUTES




Water UseSemiconductor Mfg.

Requires the highest purity water attainable, in

large amounts

Example:

For a reasonable size integrated facility

Make-up450 gallons/minute

Reclaim250 gallons/minute


PARTICULATE , DISSOLVED CHEMICALS




Water QualityMeasurement Tools

pH, ORP, Conductivity, DOProbe , electrodes based upon potentiometric

methods

Numerous manufacturers/suppliers (Sensors

Magazine Buyers Guide

pH - 79

ORP - 55

Conductivity - 86Dissolved oxygen - 70

Many offer all or several of the devices

Water QualityMeasurement Tools

Devices must be adapted to meet ANSI/ISA 76.00.02

Most manufacturers offer inline mounting provisions

for their devices, many times a bore-through Swagelok

tube fitting

Substrate manufacturers must work with the device

manufacturers to make adapter/NeSSI in-linemounting provisions available
