How To Prepare For Reopening Your Pool Facility
Effective testing and management of your pool facility can ensure that the water remains safe for pool users. Management of external facilities is also critical, with guidance on this provided in the final section of this article, see Maintaining safety in pool and leisure facilities after COVID-19.
Does Chlorine kill COVID ?
The amount of chlorine in the water needs to be properly maintained in order for its disinfectant qualities to be effective. This is why lifeguards and pool managers test chlorine and pH levels throughout the day and make adjustments as needed.
How does a cooling tower work ?
warm effluent from the plant heat exchangers enters the tower and is sprayed over the cooling tower fill. Air enters the lower portion of the tower and contacts the water in a counter-current manner to help maximize heat transfer. The cooled water collects in a sump for return to the heat exchangers, while the warm air exhaust vents to the atmosphere.
What is a heat exchanger?
Heat exchangers are devices designed to transfer heat between two or more fluids—i.e., liquids, vapors, or gases—of different temperatures. Depending on the type of heat exchanger employed, the heat transferring process can be gas-to-gas, liquid-to-gas, or liquid-to-liquid and occur through a solid separator, which prevents mixing of the fluids, or direct fluid contact.
Do water softeners remove chlorine?
When oxidizing agents—such as chlorine, chlorine dioxide, chloramine, and ozone—come into contact with both cation and anion resins under certain conditions, they can damage the resins, leading to capacity loss and inhibited performance. When present in a feed stream, oxidants degrade IX resin polymers, causing them to deform and compact over time. This compaction obstructs the flow of liquids through the resin bed, which can compromise the overall effectiveness of the IX unit, and lead to inconsistent effluent quality due to channeling in the resin bed.
How to choose the correct chemical injection pump!
Chemical injection pumps are used in a variety of applications in all kind of industries and markets. There are many manufacturers and vendors. Unfortunately, their product description is a laundry list of features and specifications that make no sense to somebody who is not constantly working with their products. Chemical injection pumps are not uber complicated, and their operating principles have been the same for many decades. Why a casual user should have to make multiple phone calls and emails to decide which pump to purchase?
Free Chlorine and DPD test!
The free chlorine DPD method immediately measures free chlorine residual—hypochlorous acid (HOCl) and hypochlorite ion (OCl– )—in water samples. If only combined chloramine— monochloramine (NH2 Cl)—is present, interference will occur and increase within seconds to minutes when free DPD reagents are used.
Boiling point of water
Boiling occurs when the vapor pressure of a liquid equals the air pressure of the atmosphere above the liquid. For example, at sea level, water boils at 212°F (100°C). As elevation increases, the amount of atmosphere above the liquid decreases, so the boiling temperature of the liquid decreases. In general, the lower the atmospheric pressure, the lower the boiling temperature of any liquid.
How does a cooling tower work ?
Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers.
How does the cooling tower startup work?
The primary goal of effective water treatment is to provide and maintain clean heat transfer, piping, and other water contact surfaces. Even before cooling tower start-up, surfaces are exposed to the elements of air and water, and that has an impact on four main areas:
Peracetic acid - the new hero in hospitals
Unlike bleach (sodium hypochlorite), it does not linger on surfaces. PAA components are completely biodegradable to its base elements of hydrogen peroxide and acetic acid. In comparison to bleach, which requires rinsing after use, PAA does not need to be rinsed off surfaces. When used correctly, it can be used to sanitize surfaces, vessels, closed systems and equipment safely, ensuring surfaces remain sanitized until required.
