example of boiler softening water hardness calculation


Filtration - GVS Filter Technology

De-ionized water; water processed through an ion exchange process by passing through a mixed resin bed to remove positive and negative ions. The purity of water is measured by its electric resistance. DEAD END FILTRATION Feed stream flows in one direction only, perpendicular to and through the filter medium to emerge as product or filtrate.

How to Make Liquid Soap (The Easy Way) - Humblebee & Me

Apr 18, 2014 · We started off by using almost all the same ingredients as my all-in-one bar.The only ingredient that was ditched was the beef tallow (no need for a hardening fat here) and the clay (to start with, at least). And we calculated it the same way as you'd run the bar soap through SoapCalc, only selecting KOH instead of NaOH, complete with a 5% superfat.

Boiler water treatment - Lenntech

The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

Water Handbook - Boiler Blowdown Control | SUEZ

Continuous blowdown, as the term implies, is the continuous removal of water from the boiler. It offers many advantages not provided by the use of bottom blowdown alone. For instance, water may be removed from the location of the highest dissolved solids in the boiler water. As a result, proper boiler water quality can be maintained at all times.
