Composite manhole covers and frames are ideal for the most corrosive environments in municipal collection systems, sewers, and industrial pretreatment applications. Sulfide rich wastewater is common in these humid and warm environments. When the humid and hot environment is combined with longer residence time, the ideal conditions of microbial induced corrosion (MIC) are produced. This mic can eventually destroy most of the sewer infrastructure without damaging the composite manhole cover or FRP manhole. This inherent corrosion resistance makes the composite manhole cover an ideal choice for production wells, outfalls, industrial pretreatment, industrial processes, equalizing tanks, tanks and pools.
Sealing property of composite manhole cover can reduce odor
It is well known that hydrogen sulfide (H2S) and other sewer gas odors exist in the collection system and sewers. The typical odor of rotten eggs is an indicator of hydrogen sulfide (H2S), and colorless gases are found in the sewer system.
Odor control is considered in the design of composite manhole cover and (FRP fiber reinforced polymer) manhole cover and manhole cover frame. These composite covers are manufactured to provide better sealing and help control odor. Plastic or composite manhole covers are also ideal for residential areas and urban environments sensitive to sewer odors. These composite manhole covers solve the problem of manhole in resorts, hotels and entertainment places. Many engineers and facility managers have been using composite coverings in parks and recreation areas, shopping centers, shopping centers, high-density development areas, water parks, beaches, trailer parks, campsites, and even a full range of island resorts.
Sealed covers and frames help reduce odor. In addition, the use of manhole seal kits can also reduce odor.
Composite well cover is an ideal choice for non-conductive applications
Many telecommunication and power utility manhole applications require non-conductive covers and seals. Composite manhole covers are very suitable for these non-conductive manhole requirements. Manholes can also be manufactured and equipped with non-conductive fiberglass ladders, platforms and railings
