Chapter 7 Tools for cleaning

Chlorides Ideal PPM

100 PPM

Silicates Ideal PPM

100 PPM

purified water should have a pH of

6.5 - 7.5

Water softeners remove?

Calcium & Magnesium

Enzymatic Products

Catalysts that can accelerate the speed of chemical reactions without being consumed by the reaction or becoming part of the product formed. Protease. Lipase. Amylase. Temperatures should not exceed 140 degrees because the enzymes become inactive.

Lipase Enzyme

Fat

Chelating agents

Have an ionic charge that allows soils with the opposite charge to break away and attach. Chemicals that hold hard water minerals in a solution, and prevent soaps or detergents from reacting with the minerals.

Reverse osmosis system

Prefilter, softener, GAC, Prefilter, vertical membrane filter, post filter.

Deionization

Process by which ions with an electrical charge are removed from water.

Distillation

Removes dissolved solids, gases and organics, along with particles, bacteria, pyrogens, and endotoxins.

Descaler

Solution used to remove the white, hard-to-remove, substance that sometimes appears on sinks and equipment.

Amylase Enzyme

Starches.

Surfactant

Surface-acting agent that lowers the surface tension of liquid so it can penetrate deeper and prevent debris from being re-deposited on item to which the soil was attached.

Emulsifier

Surrounds the particles to prevent them from re-attaching and they also help to break bonds that oils can create to trap soil.

Descalers

Used to remove chalky-powdery substance that appears of equipment and sinks.

conductivity (of water)

a measurement of the ability of water to carry an electrical current

silicate

a mineral commonly found in water that is derived from silica found in quartz and other components.

Ohm

a unit of measurement that expresses the amount of resistance to the flow of an electric current.

powdery stains or chalky build up caused by

calcium and magnesium

chloride

compound commonly found in water that is created when chlorine is combined with another element or radical

Distillation Removes

dissolved solids, gasses and organics, along with particles, bacteria, pyrogens and endotoxins

GAC

granular activated charcoal

chelating agent

have an ionic charge that allows soils with the opposite charge to break away and attach to the chelating agent

bluish or rainbow-type stains are caused by

iron and silicates

turbidity

occurs when water contains sediments or solids that when stirred make the water appear cloudy

Protease Enzyme

protein

pyrogens

pus producing organisms

Granular activated Charcoal (GAC)

removes chlorides in the water

emulsifier

surrounds particles to prevent them form re-attaching and they also help to break bonds that oils can create to trap soil

Reverse osmosis

the diffusion of water through a semi-permeable membrane to eliminate impurities that it contains

gross soil

tissue, body fat, blood, and other body substances

deionization units

used for heating/cooling therapy units and final rinse water

softeners

used to remove calcium and magnesium in water
