1. INTRODUCTION

The water plays an important role on nature. It helps to ensure the continuity of aliveness. Humans, animals and plants use the water their own needs. The water is an essential part of human life, since the water constitutes the %60-70 of the human body weight. Beside of these essential needs, humans use the water for some other needs like cleaning and fun. Whole water cannot be used directly for each activity. For example, the water must have some proper values to drunk by humans. While some water has these proper values naturally, some water does not and it requires extra treatment and purification methods. And then it should be distributed to people properly. Therefore water purification and distribution are as important as water itself.

In todays, city water can supply many needs for humans. However it cannot be drunk by humans in many cities and people have to buy drinkable water. That drinkable water is distributed within bottles. In some public institutions or homes, the drinkable water is distributed within water dispensers which is a device that provides hot and cold water quickly. Still, most of the dispenser gets the water from big water bottle which is called demijohn. This is an insufficient water supply system because it is a discrete supply and it could not provide water needs continuously. When the water of the demijohn runs out, the demijohn must be changed to get water again. This demijohn changing process may include some difficulties. For example, if there is not extra demijohn near the water dispenser the person has to wait for the full demijohn. This causes waste of time. Even if there is an extra demijohn near the water dispenser, it still includes some difficulties. Since a demijohn is 19 liter and it has unbalanced shape, it can cause some health problems. The number of water dispenser and changing frequency of the demijohns are also problem. If the number of water dispenser is not enough and demijohns are changed rarely, people cannot access the water properly, they waste their times by waiting or they can have some health problem during demijohn changing process. Because of these problems and needs, an automated central water filtering system was designed for Yeditepe University Engineering building. In this report, this automated central water system is explained.

In our project, that automated central water filtering system must have compact size, it includes long life span tools and devices, the system must be efficient, reliable and low cost. The system operates non stopping. These features can be described as the objectives of the project. On the other hand, the system must include a clean water tank, a pump, PPRC type piping system, hot and cold taps and finally there must be one dispenser for each floor. These features can be considered as the scope of the project.

The automated central water filtering system includes four major subsystems which are water supply subsystem, filtering subsystem, connector subsystem and interface subsystem. Water supply subsystem includes five parts which are piston pump, clean water tank, PPRC type piping system, hydrophore and control unit. Filtering subsystem occurs from two parts which are sand filter and reverse osmosis filter. Connector subsystem includes two parts which are hose adapter and fitting. And the interface subsystem occurs from the water prism as shown Figure 1.

2.3 Scientific Studies

In this section, some scientific studies and academic research is mentioned. Up to now, a scientific study has concerned about osmotic water purification system. Osmotic water purification systems produces a clean sugar – electrolyte drink from almost any water source [6].

A study which was published at 2000 concerned about the cleanliness of the drinking water. This study was conducted because in the beginning of the 2000’s, Canada’s drinking water has become a very important subject because of the Escherichia coli infection in Walkerton [7].

Another academic research was interested with household water purification system. In household applications, people can use ceramic filters, chlorination with storage in an improved vessel, solar disinfection and so on. However, each of these applications have limitation and the have to be improve [8].

And another scientific study was about carbon nanotube membrane for water purification. Water purification is a subject that works on nano size particles or infectives. Thereby, nanotechnology is directly influence on water purification systems. As mentioned in the article, a carbon nanotube membrane make the transport of water and antimicrobial properties faster [9].

4. DESIGN SELECTION

Selection of designs has some criteria’s like aesthetics, cost and function. These are the selected design charts for some subsystems according to criteria selection techniques. In the first part of the election group members voted for determination of evaluating criteria of each preliminary design group (Appendix 1). After that, each preliminary design alternatives were evaluated in terms of determined criteria (Appendix 2). Finally, the results are as follows;

5. CALCULATIONS

Calculation starts with measuring the head losses for each floors. Head loss calculation has two parts: Major head loss & Minor head loss. Before major head loss flow rate of each floors must be determined. Volume of the container is 150 ml. For one container, estimation time is taken as 5 seconds for filling the container. Flow rate is determined from that information and taken as 0.15 m3/h (included safety) and therefore Yeditepe Engineering building has 9 floors and total flow rate is calculated as 1.35 m3/h. After flow rate is calculated, our system pipe type is selected. In this system PPRC type pipes are used. PPRC type starts with 20 mm pipes.

Velocity in the pipe is determined from:

v= 4∗q

π∗D2 (1)

Velocity in the pipe shouldn’t exceed 1.5 m/s. If velocity is greater than 1.5 pipe diameter should be selected bigger than the first used diameter. After velocity is calculated Reynolds number should be checked. Flow regime must be observed.

ℜ= ρvDμ

(2)

Friction factor should be found from Moody chart for turbulent flow (Re>2000) and for laminar flow friction factor is;

f =64 /ℜ (3)

Length of the floors is taken as 4 meters. Eventually major head loss equation is;

h f=

f ∗lD

∗v2

2 g(4)

19

Page 20: The water purifiers   final report

This table shows flow rates, velocities, Reynolds number, head losses for each floor.

Total head loss is calculated as 1.549 m.

5.1 Major Loss

Major head loss decreases as height increases.

Velocity decreases as height increases because of the flow rate.

20

Figure 5.1.1: Major head loss vs Floor Number

Table 5.1: Results of main calculations

Figure 5.1.2: Velocity vs Floor Number

Page 21: The water purifiers   final report

5.2 Minor Loss

Minor loss occurs in a pipe due to the components below,

1. Fittings. (Elbows, tees, bends and other types)

2. Valves. (Check valves, gate valves and other types)

3. Inlet and outlet geometry.

4. Expansions and contractions in the pipe.

These components affect the flow and additional losses occur because of flow separation and

mixing due to them. Generally, total minor loss is less than the total major loss in a system.

The minor losses are associated with

Velocity (V)

Loss Coefficient (KL)

Gravity

Minor losses are calculated by:

hL=K L∗V 2

2 g

In our water purification system design we have used some fittings and valves. Number of

components used in each floor and the total numbers are shown in Figure.1.

Figure 5.2.1: Number of components used.

21

Page 22: The water purifiers   final report

According to the components presented in Figure.1, minor losses at each floor due to the

fittings and valves are calculated by using their loss coefficient values. (Table 1.)

Table 5.2.2: Minor loss and velocity calculations

As a result of the calculations, total minor loss due to the fittings is calculated as 0.194 meters

and minor loss due to valves is calculated as 0.277 meters. Therefore, total minor loss in the pipe

system is

hminor=minor fittings+minorvalves=0.194 m+0.277 m=0.471meters

Figure 5.2.3: Minor head loss change for each floor

22

Page 23: The water purifiers   final report

Up to now, minor loss and major loss calculations are done. According to their results,

total loss in the pipeline is calculated as

htotal=hmajor+hminor=1.549 m+0.471m=2.020 meters

Selection of the pump highly depends on the loss calculations in order to supply the

purified water up to the highest floor. Total height of the building is assumed as 36 meters.

Since the total head loss calculated as 2.020 meters; to design a water purification system to

this building we need to choose a pump that has a minimum head of

hpump=hbuilding+hloss=36 m+2.020 m=38 meters

7. SIMULATION

Simulation is an useful tool to observe deficiencies of the system before build the system. Designing a pipe system is a sensitive job that need inspection in each step. Also, a control system is a necessity for a closed system to operate easily. According to these constraints a control simulation was designed in Simulink.

7.1 The general control diagram

Figure x: The general control diagram

In the diagram above a well known controller was used which name is PID controller. PID controller has many advantages in control field. The most important one is fast converging capability. Thats why in this system PID controller was used. The input step block represents the desired water level of the tank. The disturbation after the pumping subsystem simulates the usage of water by individuals. Furthermore, display shows the instant water level of the tank

7.1.1 The Pumping Subsystem

In the control loop the actual dynamic system was modeled as pumping subsystem. It includes all system dynamics for example pipes, elbows, tees, dispensers and so on. Here, all calculated dimensions were given to the system to obtain more realistic result from simulation. Dispensers were modeled as “Constant head tank” in the subsystem. Also, clean water tank can be seen as “Reservoir” and “Fixed displacement pump” was simulates the actual pump in the real system. The subsystem can be seen in the following page.

28

Page 29: The water purifiers   final report

7.1.2 The results

After the diagram runs successfully the simulation gives the steady state “Water level vs Time” graph of the system. Here, when the system run the water level of the tank was drop catastrophic because the dispensers were empty. After dispensers filled up with water the system reaches steady state region. Also, tiny peak which can be considered as water usage of individuals can be seen in the figure below. In addition, this plot contains an accelerated simulation. It is obvious that it is impossible to fill up the tank 50 liters of water in 1.5 seconds safely.

8. CONCLUSION

Water is one of the most important thing for human being. Individuals should drink enough water every day for living healthy. World’s clean water resources are slightly decreasing day by day. For this reason, alternative sources for clean water come into question. Accordingly, demand for water treatment systems significantly increase in last 5 years. Companies, hospitals, schools set up water treatment systems in buildings.

In this project, an automated central water filtering system that connected to existing water dispensers was designed. This project includes only Yeditepe University Engineering Department floors. In the beginning of the project the need and the statement of the problem were obtained. Then, according to these need and problem remedial objectives and scopes were determined. In the next step, a detailed literature research was done for water filtering systems. After that, some preliminary design alternatives were generated. In preliminary design alternatives, focused on feasible solutions. Then, with the help of elimination techniques successful designs were selected.

On the next part, selected designs were examined in details. In detailed design; external dimensions, material requirements, design life and operating parameters were determined. According to detailed design results calculations & cost analysis of the system were done step by step. Finally, the simulation of the system was conducted.

To summarize, a retrofittable system was designed for Yeditepe Engineering Department floors. The system designed based on having long life span. Also, efficient and low cost appliances were considered during the design stage. With this system individuals do not wait for changing of demijohns. The most important thing that health problems caused by demijohns was be removed.
