Wastewater filtration

Pros and cons of secondary water filtration?

Pros:
• Water filtration is cost effective, and it does not require a lot of money to maintain
•It is very easy and straightforward to use

Cons:
•Thorough cleaning and care of the equipment is very vital so that they can carry out the water softening process without any hitch whatsoever

“Sewage"; used water from a community (homes, businesses and industries, stormwater runoff)

Type
Pros
Cons
Pitcher
Low upfront cost; no installation needed.
Does not remove all contaminants; filters must be changed every couple of months and will increase the yearly cost of the filter system; filtration is slow.
Faucet/On the Counter
Relatively inexpensive; can switch between filtered and unfiltered water; easy to install; ideal for drinking and cooking water.
Faucet mounted may not fit on all faucets; decreases flow rate; filters are changed every couple of months.

On the counter may require some installation and can take up space; can sometimes be expensive.
Under-sink
Filter system is out of sight; infrequent filter changes; ideal for drinking and cooking water.
Requires installation; can sometimes be expensive; takes up cabinet space.
Whole House
Whole house kept clean from one system; various processes available; if system uses filters they are changed every couple of years.
Professionally installed; very expensive.
Reverse Osmosis
Removes most unwanted contaminants.
5-step process; filters replaced frequently; very expensive; wastes a lot of water.
Distillation
Removes heavy metals, fluorides and bacteria.
Not energy efficient; takes up a lot of space; very expensive.
Ultraviolet (UV)
Does not use heat or chemicals to remove contaminants.
Any color in water will prevent UV from working; sometimes filtration is necessary prior to UV; has a low effectiveness for removing chemicals.

Hope all these helps
