Professional certification programs in the water treatment industry provide training on all of the following EXCEPT:(Required) Ethical standards Ethical standards Finding the lowest prices for products Best practices and standards 2. In addition to traditional resin-based softeners, which of the following is NOT effective at reducing hardness:(Required) Distillation Reverse Osmosis Rapid Contaminant Flushing (RCP) Portable Exchange 3. Water distillation can be effective at removing salinity from water during the distillation treatment process because:(Required) During boiling, salt disappears into the atmosphere Salt is left behind in tanks during water evaporation Salt is lighter than water and rises through special tubes None of the above 4. Reverse Osmosis (RO) treats hardness ions by:(Required) Capturing them in a membrane before washing them off Turning them into harmless pre-calcium molecules Destabilizing the ionization process Electrical charges that remove the “salinity” element 5. Portable Exchange (PE) is the process where resins are:(Required) Buried in waterproof containers Flushed down specially built sewer canals Transported elsewhere for regeneration Rapidly agitated, causing deionization of most hardness 6. In speaking with customers about the need for salinity management, the following points should be emphasized:(Required) Water sources outside the state such as Lake Mead have fallen to very low levels In-state reservoirs are experiencing capacity as low as 50 percent High salinity can lower crop yields and require extra resources for farmers Salinity at some levels is harmful to children and many small pets 7. “Salt free” treatment devices often do not reduce hardness because they do not remove:(Required) Boron Calcium Mercury Hydrogen 8. Rebate programs have been offered by communities to homeowners who:(Required) Pledge to reduce water softener use Upgrade or remove older softeners Take education training on the environment None of the above Δ
