What is a water jet eductor?
The water-jet eductor harnesses the kinetic energy of a moving liquid under pressure. An eductor entrains another liquid, gas, or gas-solid mixture, mixes it with the liquid under pressure, and discharges the mixture against a counterpressure, as shown in Figure 35-10. Application of water-jet eductors is limited by the amount of lift or suction necessary, available motive pressure, and discharge pressure. Generally, a motive-to-discharge pressure ratio of at least 3.5:1 is necessary.
What is feedforward control?
Feedforward control systems are designed to detect changes in chemical demand and compensate for them to keep the system under control. In contrast, feedback control systems react only after a system error is detected. Feedforward control is typically used to adjust corrosion inhibitor feed rate (based on changes in water temperature), chelant feed rate (based on a hardness tests), and coagulant feed rate (based on influent turbidity readings).

Why is reverse osmosis more expensive than standard filtration?
Reverse osmosis forces water through filters to remove salts and dissolved solids more effectively than standard filtration. Therefore, compared to a basic plant that only filters water, a reverse osmosis water plant may cost more due to more extensive filtration and purification required of the process.
How does reverse osmosis affect water treatment?
Multiple factors affect the total cost of water treatment. For instance, choosing reverse osmosis will increase the cost because this form of purification requires more expensive equipment to ensure purity of the water. Additionally, choosing self-cleaning filers over single-use filters will increase the upfront cost of the water treatment facility but reduce the costs of labor, replacements and total cost of ownership compared to single-use filters.
What is closed loop water treatment?
Closed loop system water treatment focuses on preventing microbial growth, corrosion and scale. As a closed system, facility managers may neglect the condition of the water in these systems. Often this comes from the false belief that if the same solution continuously loops through the system, it cannot become contaminated. However, closed loop systems can lose up to 10% of their water volume each year. This lost water requires replacement, which dilutes chemicals in the solution used for freeze or corrosion protection. Therefore, you still need to test your closed loop system water regularly.
Why is purifying water important?
While purifying water will allow it to move throughout the facility for use as process water, it likely will need additional treatment for specific applications to ensure that it performs as needed. Even the purest water can eventually pick up materials that lead to corrosion, bacteria growth or freezing. Therefore, chemical additions and the equipment used for maintaining clean water are essential components for cooling towers, boilers and closed loop systems. For instance, in closed loop systems, process water will need corrosion prevention agents added to the feed water.
Why is water in a cooling tower bad?
Cooling towers have the unique problem of exposing water to the outside. This puts the water at risk for taking on bacteria or algae. Additionally, as water evaporates from the cooling tower, it leaves minerals in the water behind, leading to scale buildup. As with all process water uses, starting with purified water for a cooling tower can mitigate some of the effects of scale and microbe growth. However, even clean water will develop contamination without proper treatment to prevent it.
