• C.

Chlorination, Rapid Mix, Flocculation, Sedimentation, Filtration

• D.

Filtration, Rapid Mix, Flocculation, Sedimentation, Chlorination

A. Rapid Mix, Flocculation, Sedimentation, Filtration, Chlorination
Explanation
The correct order of treatment processes is Rapid Mix, Flocculation, Sedimentation, Filtration, Chlorination. This sequence ensures that the water is properly mixed, particles are clumped together, settled, filtered, and finally disinfected with chlorine to remove any remaining contaminants.

### What is the purpose of the LFOM?

• A.

To maintain a linear relationship between water height and flow in the plant

• B.

To control the flow rate of the plant

• C.

To mix the coagulant with the raw water

• D.

All of the above

A. To maintain a linear relationship between water height and flow in the plant
Explanation
The purpose of the LFOM (Linear Flow Orifice Meter) is to maintain a linear relationship between water height and flow in the plant. This means that as the water height increases, the flow rate also increases proportionally, ensuring a consistent and predictable flow of water. This is important for various processes in the plant that require a specific flow rate, such as mixing coagulant with raw water or controlling the overall flow rate of the plant. Therefore, the correct answer is "To maintain a linear relationship between water height and flow in the plant."

Rate this question:

• 3.

### True or False: The chemical dose controller regulates the amount of coagulant that is added to the raw water.

• A.

True

• B.

False

A. True
Explanation
The chemical dose controller is responsible for regulating the amount of coagulant that is added to the raw water. This ensures that the correct dosage of coagulant is added to achieve the desired water treatment process. By accurately controlling the coagulant dosage, the chemical dose controller helps to optimize the treatment process and maintain water quality standards.

Rate this question:

• 4.

### The rapid mix pipe

• A.

Sends water from the entrance tank to the flocculator

• B.

Obtains adequate mixing of the coagulant with the raw water

• C.

Replaces conventional rapid mix units which require a lot of energy

• D.

All of the above

D. All of the above
Explanation
The rapid mix pipe serves multiple purposes. Firstly, it sends water from the entrance tank to the flocculator, ensuring a continuous flow of water through the treatment process. Secondly, it helps in obtaining adequate mixing of the coagulant with the raw water, which is crucial for effective coagulation and flocculation. Lastly, it replaces conventional rapid mix units that require a lot of energy, making it a more efficient and sustainable option. Therefore, the correct answer is "All of the above."

Rate this question:

• 5.

### True or False: The goal of flocculation is to cause particles to break apart

• A.

True

• B.

False

B. False
Explanation
Flocculation is a process used in water treatment where particles come together to form larger clumps or flocs. The goal of flocculation is actually to cause particles to stick together, rather than break apart. This helps in the removal of suspended solids from the water, making it easier to filter or settle out. Therefore, the correct answer is False.

Rate this question:

• 6.

### In a vertical flocculator, water flows over and under baffles, creating a velocity gradient that forces particles in the water to collide.

• A.

True

• B.

False

A. True
Explanation
In a vertical flocculator, the water flows over and under baffles, which are structures that disrupt the flow of water. This disruption creates a velocity gradient, meaning that the water flows at different speeds at different points within the flocculator. This velocity gradient causes particles in the water to collide with each other, which promotes the formation of larger flocs or clumps of particles. Therefore, the statement that water flows over and under baffles in a vertical flocculator, creating a velocity gradient that forces particles in the water to collide, is true.

Rate this question:

• 7.

### True or False: The floc weir controls the height of the floc blanket

• A.

True

• B.

False

A. True
Explanation
The floc weir is a device used in water treatment plants to control the height of the floc blanket. It is designed to allow the settled water to flow over the weir while retaining the floc particles within the treatment basin. By adjusting the height of the floc weir, operators can control the depth of the floc blanket and ensure effective settling and filtration of particles in the water. Therefore, the statement "The floc weir controls the height of the floc blanket" is true.

Rate this question:

• 8.

### How does the settled water flow into the stacked rapid sand filter?

• A.

The water flows into the bottom of the filter, moves up through all the layers of the sand, and exits from a pipe at the top of the filter box

• B.

The water flows into the top of the filter, trickle down through all the layers of sand, then leaves through the bottom pipe

• C.

The water flows through four inlet pipes, filtered through one layer of sand, and then leaves through an adjacent pipe

C. The water flows through four inlet pipes, filtered through one layer of sand, and then leaves through an adjacent pipe
• 9.

### What is the purpose of a ram pump as part of an AguaClara plant?

• A.

To raise a small portion of treated water to a higher elevation

• B.

To fill the chemical stock tanks with water

• C.

To reduce the burden placed on the plant operator

• D.

All of the above

D. All of the above
Explanation
A ram pump is used as part of an AguaClara plant to serve multiple purposes. Firstly, it is used to raise a small portion of treated water to a higher elevation, which is necessary for distributing the water to different parts of the plant or to supply water to a higher level. Secondly, it is used to fill the chemical stock tanks with water, ensuring a steady supply of water for chemical dosing processes. Lastly, it helps reduce the burden placed on the plant operator by automating the process of raising water and filling the tanks, allowing the operator to focus on other important tasks.

### What are the significant differences between the AguaClara water treatment systems that have been implemented in Honduras and those which have been implemented thus far in India?

• A.

The systems in Honduras contain an entire treatment train while the systems implemented in India consist of only a filter and doser.

• B.

The systems in India treat well water while the systems in Honduras treat surface water.

• C.

The systems in India treat a lower flow rate of water than the systems in Honduras.

• D.

All of the above.

D. All of the above.
Explanation
The significant differences between the AguaClara water treatment systems implemented in Honduras and those in India are that the systems in Honduras contain an entire treatment train, including a filter and doser, while the systems in India consist of only a filter and doser. Additionally, the systems in India treat well water, whereas the systems in Honduras treat surface water. Lastly, the systems in India treat a lower flow rate of water compared to the systems in Honduras.
