Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
Germanium(II) hydroxide is formed as a white or yellow precipitate when base is added to solutions containing Ge II, produced for example by the reduction of an acid solution of germanium dioxide, GeO 2, with hypophosphorous acid, H 3 PO 2, [2] or alternatively by hydrolysis of GeCl 2. [3]
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
Spent backwash water is either discharged without treatment to a sanitary sewer system or is treated and recycled within the plant. [4]: 22.37–22.40 Historically, backwash water was discharged directly to surface water supplies; however, direct discharge is now highly regulated through NPDES discharge permits and is often discouraged.
Dishwasher salt is a particular grade of granulated, crystalline sodium chloride intended for regenerating the water softener circuit of household or industrial dishwashers. Analogous to water softener salt, dishwasher salt regenerates ion exchange resins, expelling the therein trapped calcium and magnesium ions that characterize hard water.
