The conservation of water, its proper flow, and assured safety for home or industrial use can be achieved by reusing water through renewable energy. However, algae control is challenging even for modern wastewater treatment plants. One of the best ways of resolving this problem is by installing launder covers.
Aside from this concern, water ecosystems also face other issues, the most notable being water and wastewater treatment facilities. So how can launder covers be of any help in such a scenario?
The discussion that follows will serve as a useful reference point when choosing the right launder cover for your water and wastewater treatment facility. Let’s get up to speed on how launder covers can help water environments.
Prevent Algae Growth
Algae growth has a proven tendency of developing in water and wastewater treatment facilities. It causes changes in the hydraulic dynamics of clarifiers, which leads to obstruction of design features found in weir configurations. Once launder covers are installed, they provide an attractive and extremely low maintenance structure to help eliminate algae growth problems.
Also, larger algae can dislodge and move around in plants that utilize ultraviolet disinfection technology. If the floating algae ends up covering UV bulbs, this may cause bulb failure and render UV bulbs ineffective, which are unfortunately very expensive to replace.
That’s why the installation of reliable launder covers, like IEC Covers, is recommended to help prevent algae growth in water and wastewater treatment plants. This would save money on repairs and UV bulb replacement at the same time.
Control Gas And Odor Emissions
Launder covers are useful in providing a continuous protective environment above the effluent stream. They can contain odor and gas to prevent environmental pollution and protect the health of workers in the area.
A reliable and corrosion-free launder cover system prevents direct sunlight from reaching the elevated growth areas of the weir and clarifier launder. Since launder covers serve as odor control hoods, they trap noxious gases that are generated during wastewater treatment processes.
Provide Essential Value To Water Environments
Custom designed launder covers can be placed in rectangular and round tanks, providing essential value for different water and wastewater operations. This page will teach you everything about wastewater treatment.
Here are the advantages of installing launder covers in water environments:
- Continuous inhibition of algae growth
- Lightweight and cost-effective solution for water problems
- Operable access for safety inspections and preventive maintenance
Maintain Weir Structural Integrity And Function
Eliminating direct sunlight inhibits algae growth, which also enhances the flow consistency of weir and reduces the need for maintenance. Launder covers shield other openings where access is normally required, but for safety reasons they need to be covered when not being used.
You can request custom-designed launder covers according to your preferred requirements. Custom-designed launder covers can be used in both round and rectangular clarifiers, as well as channels, sludge thickeners, and other openings.
Acts As Debris Barrier
Plastic bags, leaves, dead tree branches, and other windblown debris often lands in water environments. Launder covers help prevent such waste materials from ending up in your water and wastewater plant.
Also, aside from preventing debris from entering the water stream, launder covers can also be helpful in containing localized odor emissions if present in the weir area (effluent trough). Choosing fiberglass launder covers helps seal water environments in order to control odor.
Protect Launder From Weather
Strong winds, storms, snow, or heavy rainfall may introduce debris to water environments. Installing launder covers helps protect them against debris and damage caused by natural disasters. Choosing high-quality launder covers will ensure that they can withstand harsh weather conditions while protecting water and wastewater treatment plants.
Here’s a quick guide for when you are choosing launder covers:
- NSF/ANSI Certified: Choose launder covers that are NSF or ANSI 61 certified. Also, opt for launder covers made of AWWA F101 compliant materials. NSF/ANSI Standard 61 or NSF-61 refers to a national standard relating to water treatment, establishing strict requirements and controls for equipment coming in contact with potable water or other products supporting the potable water production.
- Quality Make: Select launder covers with superior strength and corrosion resistance that use FRP components to ensure long and maintenance-free service life. Choose clarifier launder covers that utilize fiberglass and stainless steel hardware, specifically made for municipal or industrial wastewater treatment purposes. These launder covers are easy to use, ensuring smooth operation and meeting the required NPDES effluent levels of Total Suspended Solids or TSS.
- ISO Certified: Choose an ISO 9001 certified launder cover for manufacturing facilities.
Conclusion
Launder covers provide great protection against debris, harsh weather conditions, and direct sunlight. They further help protect weir structures, prevent algae growth, and are handy in avoiding the potential damage that algae can do to UV bulbs in treatment facilities using UV disinfection technology.
Choosing high-quality launder covers would mean having long-term peace of mind that your water quality is preserved and wastewater treatment operations can function smoothly.
