Disadvantages of other processes:

Chlorine
(Disinfection process)

    * Highly toxic greenish yellow gas

• EPA's maximum residual disinfection levels (MRDLs) are 4 mg/l (liter) for   

  chlorine

•  1 liter = 0.26 gallons = 4.16 cups

• 8 cups water per day contains 8 mg chlorine

• Operator hazard concerns because of corrosive, toxic nature

• Purchase and storage costs are ongoing

• The chlorine residual, even at low concentrations, is toxic to aquatic life   

  and may require dechlorination

• Chlorine oxidizes organic matter in wastewater, sometimes creating

  compounds that could be harmful to humans and the environment

Reverse Osmosis (Purification process)

• Uses a membrane that is semi-permeable, allowing the fluid that is being 

  purified to pass through it, while rejecting the contaminants that remain

• RO units use a lot of water. They recover only 5 to 15 percent of the water 

  entering the system

• Discharges contaminated wastewater

• For every 5 gallons of treated water per day, It may discharge 40-90 gallons

  of wastewater

• The storage unit for treated water will support bacteria growth unless

   regularly disinfected

• A pump may be needed to increase household water pressure and

  enhance membrane efficiency

• Ongoing costs for energy usage and membrane replacement

• Loss of trace minerals

UV Mercury Lamp (Disinfection process)

• Hazards of mercury

• Generates high amounts of heat, causing risks of explosion

• Ongoing energy costs

• Traces of any sort of ash, salts, metal oxides, or alkalis can leach

   into hot quartz and cause strains which can weaken the quartz

• A ballast is required to limit the current flowing through the lamp and

  also to provide any necessary high voltage starting pulses

• Sporadic photon pulses may lead to inefficiencies of disinfection

• Life expectancy of mercury bulb is 3- 6 months

• Ongoing bulb and ballast replacement costs
 

Carbon Filters (Purification process)

• Low contaminant reduction capacity

• Tendency to clog and restrict water flow

• Encourages growth of bacteria in the filter

• Particle size effects removal rates

• Frequent filter changes often required

• No reliable way to determine if the carbon is saturated with

  contaminants and needs replacing

• Will NOT effectively remove bacteria, nitrates or metals

Distillation (Disinfection process)

• Not very effective in removing organic chemicals, like

  pesticides and herbicides, because these vaporize at a                                    

  lower temperature than water

• Distillers produce water at a very slow rate

• The average cost is 18-20 cents per gallon of water

• Water will still need to be filtered for organic contaminants

• Distillers have small capacities and use considerable   

  energy to process water

• Because of the small capacities, distillers are limited to 

  point-of-use systems

Boiling (Disinfection process)

• Time consuming and costly in terms of electric or gas bill

• Some viruses are resistant to temperatures double that of 

  boiling water in their dormant state

• Boiled water loses volume, causing toxic chemicals in a

  higher concentration

• Can give water a stale or flat taste

• Limited capacity

• Requires separate storage of treated water
