This project has awarded Distinction and I have put a lot of effort to study on electrical and electronic software and knowledge. I dont have electrical background but I willing to learn for improvement.
After assembly, again it has to be tested. This test
is called first quality test to avoid error and achieve the objective of the
project.
When no switch on power supply, there is no current
pass through water level controller. The red and green L.E.D will not light up.
After switch on power supply, the red L.E.D will
light up to show the voltage regulator is functioning. Then pour the water as
shown in the above picture. The water will pass through filter and flow to
aquarium pump arcyclic fiber tank.
The water level sensor will detect the water and
send signal to water controller and at the same time light up green L.E.D. The
water level controller will actuate the sensor to activate the water flowing
from aquarium pump arcyclic fiber to another acryclic fiber (toilet).
Once again the toilet tank of water level sensor
detect the water is maximum level, it send signal to water level controller to
stop the pump from pumping water and at the same time green L.E.D will
illuminate. Consequently, water will not flowing anymore from the pump.
The picture below shown that the project has completely success built in Kuching in the year 2003. This project is built for whole resident uses while my project is built for individual house usage.
Practice of Water Reuse and Recycle
Urban
Reuse
The more
common applications include irrigation of public access areas (residential
lawns, parks, school yards, highway medians, golf courses, and landscaped areas
surrounding hotels, offices, and commercial buildings). Other uses have
included vehicle washing facilities, reflecting pools and fountains, fire
protection, and toilet and urinal flushing. Urban reuse systems typically
involve dual distribution systems that deliver reclaimed water to customers in
a network of distribution piping separate from the potable distribution system.
Examples of such systems are the Irvine Ranch Water District in California and
the cities of St. Petersburg and Cape Coral in Florida. In St. Petersburg,
Florida the dual distribution system has reduced potable water usage by 50%.
Agricultural
Reuse
As Table
1 reflects, there are several different agricultural reuse categories.
California and Florida have extensive programs accounting for between 34 and
63% of the total volume of reclaimed water used — depending on the source of
the information. Prominent examples of agriculture reuse include the Cities of
Orlando and Tallahassee in Florida. The system in Orlando is part of a joint
program called Conserv II between the city of Orlando and Orange County,
Florida.
Groundwater
Recharge
Water
Factory 21 in Orange County, California has been conducting reuse research and
injecting effluent via wells into the coastal aquifer since 1976. WWTP effluent
is combined with well water prior to injection. This indirect potable reuse has
a psychological advantage in that there is a loss of identity between reclaimed
water and groundwater. In Florida, the previously mentioned Conserv II program
in Orlando also involves rapid infiltration basins for groundwater recharge.
Augmentation
of Potable Supplies
Besides
the indirect potable reuse just mentioned under the heading of groundwater
recharge, direct potable reuse is also possible. There are major psychological
barriers to this application although considerable research has been conducted
in Denver, San Diego, and Tampa. Currently direct potable reuse is not
practiced anywhere in the United States.
Environmental
Enhancement
This
category includes the use of reclaimed water for the creation or enhancement of
wetlands, stream augmentation, and recreational and aesthetic impoundments.
Examples of two major wetland enhancement systems to provide wildlife habitats
as well as additional effluent treatment prior to discharge are sites at
Orlando, Florida and Arcata, California. Other applications in this category
include the creation of recreational lakes and snowmaking.
Industrial
Reuse
In-plant
recycling is an important part of many wet process industries. Separate from
this, industrial applications of reuse (WWTP effluent) water include:
evaporative cooling, boiler-feed water, process water, and irrigation of plant
grounds (Goto, 1995). The cooling water application and the utility power
industry are by far the predominant industry reuse situations.
