Water Treatment

Last week, class of 2m are required to make a scrapbook about water treatment.

Water conservation
Water conservation can be defined as:
  1. Any beneficial reduction in water loss, use or waste as well as the preservation of water quality.
2. A reduction in water use accomplished by implementation of water conservation or water efficiency measure
  1. Improved water management practices that reduce or enhance the beneficial use of water. A water conservation measure is an action, behavioral change, device, technology, or improved design or process implemented to reduce water loss, waste, or use. Water efficiency is a tool of water conservation. That results in more efficient water use and thus reduces water demand. The value and cost-effectiveness of a water efficiency measure must be evaluated in relation effects on the use and cost of other natural resources (e.g. energy or chemicals)

Importance of Conserving Water

Water is too good to waste because it is
essential for life. Desalinization is too expensive for most communities. Once
water is washed into a sewer system, it's mixed with chemicals that are
difficult and very expensive to remove. Watering lawns too often will wash
pesticides and herbicides into the sewer system. The water we drink is recylced
from the water we use, so it's important to not pollute it.

Steps to
Conserve Water
Repair faucets to eliminate leaks in kitchen and bathrooms.
Install retrofit devices on faucets to reduce flow.
Repair toilets to eliminate leaks
Install water displacement devices in toilet tanks to reduce flow.
Replace with new low volume toilets.
Install a high efficiency clothes washer (average 27 gallons per
Install a water efficient dishwasher (average six to seven gallons
   per load).
