Total Swimming Pool Care: Granada Hills, Ca. 91344
Do you know what’s in there?
Do you know what’s IN YOUR pool?
No seriously, do you?
Swimming pools are great…when they are clean. And even when they ARE clean, it’s hard to tell how clean they really are just by looking at it.
Sure you’ve got that scoop net that lets you skim off the surface stuff like leaves or other debris, but that’s like taking a wet washcloth and wiping off your arm.
You know that you STILL need to shower and scrub up in order to be as clean as possible. Now, imagine if all you ever did was use a wet washcloth now and then and only took a REAL shower once a month.
How healthy do you think you’d stay?
How CLEAN do you think you’d REALLY be?
Luckily for you, showers can be had on a daily basis.
Unfortunately, when it comes to REALLY cleaning your pool, well that can become a rather tedious process and often times we’d rather take the wet washcloth approach.
Sanitation methods include a water filter to remove pollutants, disinfection to kill infectious microorganisms, swimmer hygiene to minimize the introduction of contaminants into pool water, and regular testing of pool water, including chlorine and pH levels.
Contaminants and Disease
Swimming pool contaminants are introduced from environmental sources and swimmers. Affecting primarily outdoor swimming pools, environmental contaminants include windblown dirt and debris, incoming water from unsanitary sources, rain containing microscopic algae spores and droppings from birds possibly harboring disease-causing viruses.
Contaminants introduced by swimmers can dramatically influence the operation of indoor and outdoor swimming pools. Sources include micro-organisms from infected swimmers and body oils including sweat, cosmetics, suntan lotion, urine, saliva and fecal matter. In addition, the interaction between disinfectants and pool water contaminants can produce a mixture of chloramines and other disinfection by-products.
Pathogenic contaminants are of greatest concern in swimming pools as they have been associated with numerous recreational water illnesses. Public health pathogens can be present in swimming pools as viruses, bacteria, protozoa and fungi. Diarrhea is the most commonly reported illness associated with pathogenic contaminants, while other diseases associated with untreated pools are Cryptosporidiosis and Giardiasis. Other illnesses commonly occurring in poorly maintained swimming pools include swimmers ear, skin rashes and respiratory infections.
The journal Environmental Science & Technology reported that sweat and urine react with chlorine and produce trichloramine and cyanogen chloride, two chemicals dangerous to human health.
Maintenance and Hygiene
Contamination can be minimized by good swimmer hygiene practices such as showering before and after swimming, and not letting children with intestinal disorders swim. Effective treatments are needed to address contaminants in pool water because preventing the introduction of pool contaminants, pathogenic and non-pathogenic, into swimming pools is impossible.
A well-maintained, properly operating pool filtration and re-circulation system is the first barrier in combating contaminants large enough to be filtered. The removal of filterable contaminants reduces the impact on the disinfection system thereby limiting the formation of chloramines, restricting the formation of disinfection by-products and optimizing sanitation effectiveness. To kill pathogens and help prevent recreational water illnesses, pool operators must maintain proper levels of chlorine or another sanitizer.
Over time, calcium from municipal water tends to accumulate, developing salt deposits in the swimming pool walls and equipment (filters, pumps), reducing their effectiveness. Calcium also absorbs chlorine and prevents proper performance of added chemicals. Therefore, it is advised to either completely drain the pool, and refill it with fresh water, or recycle the existing pool water, using reverse osmosis. The advantage of the latter method is that 90% of the water can be re-utilized.
Pool operators must also store and handle cleaning and sanitation chemicals safely.
Prevention of Diseases in Swimming Pools and Spas
Disease prevention should be the top priority for every water quality management program for pool and spa operators. Disinfection is critical to protect against pathogens, and is best managed through routine monitoring and maintenance of chemical feed equipment to ensure optimum chemical levels in accordance with state and local regulations.
Modern digital equipment when used in conjunction with automatic chemical feeders results in stable pH and chlorine levels. Local jurisdiction may demand a wait time if chemicals are added by hand to the water so that swimmers are not injured.
Chemical parameters include disinfectant levels according to regulated pesticide label directions. pH should be kept between 7.2-7.8. Human tears have a pH of 7.4, making this an ideal point to set a pool. More often than not, it is improper pH and not the sanitizer that is responsible for irritating swimmers’ skin and eyes.
Total alkalinity should be 80-120 ppm and calcium hardness between 200 – 400 ppm.
Good hygiene at swimming pools is also important for reducing health risk factors at swimming pools and spas. Showering before swimming can reduce introduction of contaminants, and showering again after swimming will help to remove any.
Those with diarrhea or other gastroenteritis illnesses should not swim within 2 weeks of an outbreak, especially children. Cryptosporidium is chlorine resistant.
To minimize exposure to pathogens, swimmers should avoid getting water into their mouths and never swallow pool or spa water
Systems and Sanitation Methods
Chlorine and Bromine Methods
Conventional halogen-based oxidizers such as chlorine and bromine are convenient and economical primary sanitizers for swimming pools and provide a residual level of sanitizer that remains in the water. Chlorine-releasing compounds are the most popular and frequently used in swimming pools whereas bromine-releasing compounds have found heightened popularity in spas and hot tubs. Both are members of the halogen group with demonstrated ability to destroy and deactivate a wide range of potentially dangerous bacteria and viruses in swimming pools and spas. Both exhibit three essential elements as ideal first-line-of-defense sanitizers for swimming pools and spas: they are fast-acting and enduring, they are effective algaecides, and they oxidize undesired contaminants.
Swimming pools can be disinfected with a variety of chlorine-releasing compounds. The most basic of these compounds is chlorine, however, its application is primarily in large commercial public swimming pools. Inorganic forms of chlorine-releasing compounds frequently used in residential and public swimming pools include sodium hypochlorite commonly known as liquid bleach. Chlorine residuals and inorganic chlorine-releasing compounds break down rapidly in sunlight. To extend their disinfectant usefulness and persistence in outdoor settings, swimming pools treated with one or more of the inorganic forms of chlorine-releasing compounds can be supplemented with cyanuric acid—a granular stabilizing agent capable of extending the active chlorine. Chlorinated isocyanurates, a family of organic chlorine-releasing compounds, are stabilized to prevent UV degradation due to the presence of cyanurate as part of their chemical backbone.
Chlorine reacting with urea in urine and other nitrogen-containing wastes from bathers can produce chloramines. Chloramines typically occur when an insufficient amount of chlorine is used to disinfect a contaminated pool. Chloramines are generally responsible for the noxious, irritating smell prominently occurring in indoor pool settings. A common way to remove chloramines is to shock the pool with a high dose of inorganic chlorine sufficient to deliver 10 ppm chlorine. Regular shocking (every two weeks in summer) helps to eliminate these unpleasant odors in the pool. Levels of chloramines and other volatile compounds in water can be minimized by reducing contaminants that lead to their formation.
Medium pressure UV technology is used to control the level of chloramines in indoor pools. It is also used as a secondary form of disinfection to address chlorine tolerant pathogens. A properly sized and maintained UV system should remove the need to shock for chloramines, although shocking would still be used to address a fecal accident in the pool. UV will not replace chlorine, but is used to control the level of chloramines, which are responsible for the odor, irritation, and enhanced corrosion at an indoor pool.
Private Pool Filtration
Filter Cleaning, Maintenance & Service – Imagine if the drain plug in your sink got clogged up? What would happen to the water in your sink? Yeah, this is an area that you need to keep in mind and an area you may want to seek out help with.
An electrically operated water pump is the prime motivator in recirculating the water from the pool. Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of the pool. Residential pool pumps are typical run for 4 hours per day in winter (when the pool is not in use) and up to 24 hours in summer. To save electricity costs, most pools run water pumps for between 6 hours and 12 hours in summer with the pump being controlled by an electronic timer.
Most pool pumps available today incorporate a small filter basket as the last effort to avoid leaf or hair contamination reaching the close-tolerance impeller section of the pump
A pressure-fed sand filter is typically placed in line immediately after the water pump. The filter typically contains a media such as graded sand. A pressure fed sand filter is termed a ‘High Rate’ sand filter, and will generally filter turbid water of particulates no less than 10 micrometers in size. The rapid sand filter type are periodically ‘back washed’ as contaminants reduce water flow and increase back pressure. Indicated by a pressure gauge on the pressure side of the filter reaching into the ‘red line’ area, the pool owner is alerted to the need to ‘backwash’ the unit. The sand in the filter will typically last five to seven years before all the “rough edges” are worn off and the more tightly packed sand no longer works as intended.
Some filters use diatomaceous earth to help filter out contaminants. Commonly referred to as ‘D.E.’ filters, they exhibit superior filtration capabilities. Often a D.E. filter will trap waterborne contaminants as small as 1 micrometer in size. D.E. filters are banned in some states, as they must be emptied out periodically and the contaminated media flushed down the sewer, causing a problem in some districts’ sewage systems.
Other filter media that have been introduced to the residential swimming pool market since 1970 include sand particles and paper type cartridge filters. These units can be ‘daisy-chained’ together to collectively filter almost any size home pool. The cartridges are typically cleaned by removal from the filter body and hosing-off down a sewer connection. They are popular where backwashed water from a sand filter is not allowed to be discharged or goes into the aquifer.
Automated Pool Cleaners
Automated pool cleaners more commonly known as “Automatic pool cleaners” and in particular electric, robotic pool cleaners provide an extra measure of filtration, and in fact like the handheld vacuums can microfilter a pool, which a sand filter is unable to accomplish.
