This is usually prepared by either a base-exchange method using sodium zeolite, by a lime-soda ash process, or by the addition of sodium hexa-metaphosphate. In addition to the bacteria derived from the mains water, additional flora of Bacillus spp. and Staphylococcus aureus may be introduced into systems which use brine for regeneration and from the chemical filter beds which, unless treated, can act as a reservoir for bacteria. 

Mild alkalis have less effect, but again temperature and concentration are important factors. Sodium carbonate is used in wool scouring and small quantities of ammonia are sometimes added to a dyebath. Slight damage caused by an alkali in scouring can render the fibre less resistant to subsequent processes. Ammonia, ammonium carbonate, borax, sodium hexa-metaphosphate, tetrasodium pyrophosphate, and sodium triphosphate can be used at temperatures up to 60 to 70°C (140° to 158°F) with safety. 

The water was treated with sodium, hexa-metaphosphate, before it entered the piping system of the house. 

Sodium Phosphate. The hexa-metaphosphate (generally under the proprietary name calgon) is used to control the viscosity of slips in the pottery and vitreous enamel industries.
