Sewage Wastewater Chlorine Tablet Precautions

Brent Hardbass, PE

English: Calcium hypochlorite formula

Image via Wikipedia

Calcium hypochlorite is generally the approved septic wastewater chlorine tablets. It is very important that you do not confuse isocyanurates with calcium hypochlorite. Isocyanurates are generally used for swimming pool chlorination, not wastewater disinfection. You should never use isocyanurates for sewage wastewater disinfection or septic tank chlorination.

We can break down wastewater treatment systems into two categories; high and low wastewater flow rates. A high flow system is normally a large residential wastewater treatment system or commercial wastewater treatment system. The high flow systems generally use a product similar to NORWECO’s Bio-sanitizer disinfection tablets. The Bio-sanitizer tablets dissolve faster than the low flow chlorine tablets. Low flow systems require specially designed tablets, which are similar to the NORWECO Blue Crystal sanitizing tablets.

Low flow systems or systems that do not have flow equalization (FE) generally use of Blue Crystal type chlorine tablet. These tablets are specially design to work under these low flow conditions. The base material is still calcium hypochlorite, with a different tablet-bonding agent. If you are looking for low flow chlorination tablets, then we recommend NORWECO’s Blue Crystal disinfection tablets.

Commercial wastewater treatment systems, generally, have higher flow rates. The calcium hypochlorite tablets used in this application are designed for these higher flows. Commercial systems can flow in excess of 300 gallons per minute flows. NORWECO produces a specially designed calcium hypochlorite tablet that is known as “bio-sanitizer disinfecting tablets.” In both the high flow and low flow applications, the tablet size is the same (2 5/8 inch diameter, and 3/16 of an inch thick). Standard chlorine-tablet-feeder-tubes, generally 3 inches in diameter, readily accept this size of tablet. We recommend the NORWECO biodynamic tablet feeder LF series, as the best on the market.

Chlorine tablet handling precautions: Chlorine tablet vapors and the calcium hypochlorite tablets can be very toxic to your hands, face and lungs. In addition, these calcium hypochlorite tablets react quite violently with grease, oils and other petroleum products. In addition, dechlorination tablets and other types of chlorine can react quite violently with the calcium hypochlorite tablets.

Whenever you handle calcium hypochlorite tablets, you should use a protective face shield and rubber gloves. Be especially careful when you first open the tablet storage container. Large amounts of chlorine-based gases release when you first open the container. Never, breathe these gases in. The gases can damage your lungs, your face and other mucous membranes, such as your eyes. Handle calcium hypochlorite tablets caution.

How much chlorine should you expect to use?: A standard three bedroom 2-bath home should use about 12 chlorine tablets every four months. This assumes that a three bedroom two bath home has six persons living in it. A significantly higher tablet usage rate could indicate excessive wastewater flow, caused by a leaking faucet or toilet. Also, jerry-rigged and/or poorly designed chlorine tablet feeders could be the cause. First, check for water leaks, and then consider replacing your wastewater chlorine tablet feeder. For example, a jerry-rigged tablet feeder could be made with a 4 inch Tee with a vertical three-inch PVC tube. In this case, the chlorine tablets could be in constant contact with the wastewater. The tablets in it dissolve more quickly because the bottom tablet is partially submerged in the water. A good replacement consideration would be the NORWECO biodynamic LF series feeder.

The price you pay per chlorine tablet can vary greatly from vendor to vendor. Shopping online for your chlorine tablets is a very good option. For example, you can easily spend $100 or more, if you have a larger wastewater treatment system. If you can save 20% or more on the price that you pay per tablet, you can save thousands of dollars per year. It pays to shop for the best price.

In conclusion, calcium hypochlorite tablets should be the only type tablets you use in your wastewater treatment system. Make sure you take the proper precautions, if you maintain the system yourself. Use personal protective equipment at all times when handling the chlorine tablets. Make sure you store your chlorine tablets and clean, dry areas away from all petroleum products and other chlorine. Keep an eye on your chlorine tablet consumption. If you are using too much chlorine for the size of your wastewater treatment system, you should consider looking for water leaks in your system and/or replacing your wastewater tablet feeder with a NORWECO biodynamic LF series feeder or equivalent.

Modern Commercial Sewage Lift Stations

Bruce Hardboss, PE

Sewage pump stations which can be utilized in sewage collection methods, also known as lift stations, are frequently made to handle raw sewage

The ABS EffeX range of submersible sewage pump...

that’s supplied through subterranean gravity-given pipelines (piping that happens to be laid in a location to make sure that a liquid can easily flow one path subjected to gravity). Sewage is given directly into and saved within below grade tank, generally referred to as a wet well. The well is usually equipped by having electro-mechanical instrumentation to measure the amount of sewage available. Whenever the sewage level goes up to some predetermined point, a pump motor will be began to raise up the sewage ” up ” by means of a pressurized conduit system termed as a sewer pressure main or maybe rising primary in which the sewage is discharged right into a gravity manhole. Then the pattern commences all over again before the sewage reaches its destination – often a treatment plant. With this method, lift stations are utilized to move waste to greater elevations. Within the situation of high sewage flows in to the well (for instance throughout peak flow periods and wet weather) additional pumps are generally used. If this sounds like inadequate, or perhaps in the situation of failure from the moving station, the sewer system can back up, resulting in a sanitary sewer overflow – the release of raw sewage in to the environment. Most facilities are quite concerned about the hazards of raw sewage releases. For example, in San Diego, CA, the beaches were shut down following most major rainfall events due to sewage releases. The bad press over many years prompted San Diego to build it’s new Point Loma facility.

Sewage pumping stations are usually designed to ensure that one pump or multiple pumps will handle normal peak flow conditions. Redundancy built  into the system to ensure that when anyone pump has run out of service, the rest of the pump or pumps will handle the designed flow. Present day designs include lots of electronic remotes on the market designed specifically with this application. The storage amount of the wet well between your ‘pump on’ and ‘pump off’ configurations are designed to minimize pump on-off cycles, however is not such a long enough retention time to promote septic conditions in the tank wet well. If the sewage remains static for too long a period of time, then ecessive corrosion and/or explosive conditions can occur. Also, some regulatory bodies require a minimum height to cross-sectional area requirement to minimize these effects.

Sewage pumps are nearly always centrifugal pumps with open impellers and therefore are specifically fashioned with a sizable open passage in order to avoid blocking with debris or winding debris around the impeller. A 4-pole or 6-pole AC induction motor normally drives the pump. Some pumps do not rely the ability to pass large solids, and typically more compact sewage pumps,  macerate any solids inside the sewage breaking them into more smaller parts which can easily pass through the impeller.

The inside of the sewage pump station is an extremely hazardous. Poisonous gases, for example methane and hydrogen sulfide, build up within the wet well an ill-outfitted person entering the well could be rendered unconcous very rapidly. Any entry in to the wet well necessitates the correct limited space entry of a hazardous atmosphere. To reduce the requirement for entry, the wet wells are generally located outside, which minimizes some confined space entry concerns.

Traditional sewage lift stations incorporate both a wet well along with a ‘dry well’. Frequently fundamental essentials same structure separated by an interior divide. Within this configuration pumps are installed on the bottom of the dry well to ensure that their basins are below level of pump start, priming the pump as well as increasing the accessible NPSH. Although nominally isolated in the sewage within the wet well, dry wells are subterranean, confined spaces and require appropriate safeguards for entry. Further, any failure or leakage from the pumps or pipe-work can discharge sewage into the dry well with complete flooding. Consequently, the electrical motors are usually mounted over the overflow, top level from the wet well, usually above walk out, and drive the sewage pumps with an extended vertical shaft. To safeguard the above mentioned ground motors from weather, small pump houses are usually built, that also incorporate the electrical switch-gear and control electronics. Fundamental essentials visible areas of a conventional sewage moving station even though they are usually more compact compared to subterranean wet and dry wells.

More contemporary sewage pumping stations don’t require a dry well or pump house in most cases comprise merely a wet well. Within this configuration, submersible sewage pumps with a combined motor unit are mounted inside the wet well itself, immersed inside the sewage. Submersible pumps are installed on two vertical guide rails and seal onto a permanently fixed ‘duckfoot’, which forms both a mount in addition to a vertical bend for the discharge pipe. Maintenance is performed by elevating the submersible pumps with a chain from the duckfoot, or they are extracted by guide rails to the maintenance (normally at the ground surface) level. The pumps are re-installed by simply reversing this procedure. Because the motors are sealed and weather isn’t a concern, no above ground structures are needed, except a control panel which contains the electrical switch-gear and control systems. In the past 20-years or so, pump materials have allowed us to design sealed submersible-pumps that can withstand being submerged in relatively caustic conditions. In the 1960′s and earlier, few true submersible pumps were available, therefore pump stations that contain large dry-wells were predominant. Modern sewage lift stations rely almost exclusively on submersible pumps.

When we balance safety and reliablility concerns, and require more compact footprint and visibility, submersible pump sewage pumping stations have almost completely replaced traditional sewage lift stations. Further, a refit of the traditional pumping station usually involves transforming it right into a modern lift station by setting up submersible pumps within the wet well, destroying the pump house. Wet well designs, utilizing submersible pumps are the future of wastewater lift stations.

Sewage Wastewater Treatment – Disinfection Via Chlorine UV and Ozone

 

Article by Hardboss

In wastewater treatment, the effluent sewage stream is sometimes disinfected. Disinfection is accomplished, generally, by either using contact

Clean drinking water...not self-evident for ev...

chlorination, ultraviolet (UV) processes or by applying Ozone. Disinfection is generally required if the waste stream has the potential to come into contact with the general population, or drinking water supplies. The overall goal is to reduce the infection risk to the surrounding population.

Chlorine Disinfection

 

The least expensive and most common type of disinfection is by chlorination. Generally, the wastewater stream passes over chlorine tablets (known as contact chlorination) which increases the chlorine concentration in the wastewater. The increased chlorine concentration is very effective in killing most harmful pathogens.

The second type of contact chlorination is a batch process. In batch application(s), the wastewater fills a large tank, where sufficient chlorine is added to kill most pathogens. In batch processing, the chlorine is added manually as a powder or as chlorine gas.

In sensitive areas, the chlorinated wastewater stream can be passed through de-chlorination tablet feeders to neutralize the chlorine prior to discharge. One disadvantage is that salts are introduced into the environment via the chlorination/de-chlorination process.

Ultraviolet Disinfection

Ultraviolet disinfection (UV) uses no chemical in the treatment, and the treated water is not subjected to the salts produced in chlorination processes. One significant disadvantage is that the UV disinfection systems require constant maintenance and a power source. UV light bulbs or windows must be cleaned regularly and bulbs replaced.

Ozone Disinfection

Third type of chlorination method is Ozone. Ozone if a very effective and fast-acting disinfection method. Generally, the Ozone is produced onsite and is introduced into the waste stream. Ozone disinfection requires higher power supplies to run, but is relatively safe. Maintenance requirements complicates the Ozone process and its reliability.

We recommend using Chlorination tablet feeders and the applicable Chlorine tablets to disinfect most wastewater streams. We feel that the NORWECO Chlorine tablet feeders, and the NORWECO Disinfection tablets are the best on the market. Please visit our online store for pricing.

Commercial Wastewater Pumping Stations Review of Bio-microbics’ BioSTEP® and NORWECO

 

Article By Bruce Hardboss, PE

 

 

BioSTEP® screened pumping schemes are versatile ticker packet designed to transferral screened liquid in numerous size-diam, decentralized accumulation applications. BioSTEP® is a registered trademark of Bio-MICROBICS.  Bio-MICROBICS claims the following; “BioSTEP® screened pumping systems are designed so that once installed, all normal operation and maintenance can occur without the messy removal of system components. BioSTEP screened pump vaults utilize the patented SaniTEE® screening technology to screen and deflect solids rather than collect and hold them like other filtering technologies. ” (see http://www.biomicrobics.com/?p=67&s=10) This article is the sole property of BnB Alternative Septic Solutions, LLC and does not necessarily reflect NORWECO’s position. We feel that our evaluation is technically correct and we welcome constructive comments.

At BnB Alternative Septic Solutions, LLC our registered professional CIVIL Engineers prefer simple NORWECO grinder pump configuration(s) or the robust BK-2000 filtration system followed by a standard NORWECO pump unit. Bio-MICROBICS advocates their BioSTEP® product as superior to filtration systems. We strongly feel that for flows up to 2000 GPD, a BK-2000 system provides robust filtration and is a simpler approach when compared to the BioSTEP® system. We also feel that adding grinder pump units to a standard septic tank outlet is also a “more simple design.”

Either a NORWECO pump vault or a simple grinder pump installation in the septic tank fluids compartment or a BK-2000 filtration unit paired with a standard lift pump unit will give comparable performance and possibly increased reliability. We have seen very few problems with particle clogging.

We recommend adding NORWECO Bio-Gem organic digester or Bio-PERC to the wastewater up-stream to promote solids breakdown to any configuration, including the BioSTEP®. A typical NORWECO pump package would be as noted below:

Typical NORWECO Pump Package

(There are multiple configurations available)

Also, a good option which is robust and similar to the Biomicrobic’s approach is to add a BK 2000 filtration unit to the septic tank outlet, then feed the filtered outlet to the above pump unit. In this case a single liquid pump is adequate since solids are removed and TSS is lowered to under 10 mg/L.
