01PP water storage module
The rainwater storage module is made of renewable polypropylene material, there are different specifications and sizes of the grid-like flat plate assembled into a modular box, and then each box is placed into a continuous rainwater "matrix" pool. Because of its grid permeable structure, the structure of the material occupies less than 5% of the space, that is, the water storage space of the module reaches more than 95%, rainwater can be freely exchanged in which the flow.
The main role of rainwater storage module is rainwater collection, storage, and storage. When it rains, the peak flow of rainwater runoff is temporarily stored in it, and then the rainwater is slowly discharged from the rainwater collection tank after the maximum flow declines. This can not only avoid the peak of rainfall flooding, rainwater recycling, but also to avoid the pollution of the initial rainfall on the water body, but also to play a positive role in the scheduling of drainage between the drainage area.
02 assembled modular cistern
Water storage module structure is simple and lightweight, through the combination of modules, you can quickly build different sizes of rainwater cisterns in the ground. Modular cistern in the completion of water storage at the same time, can form a stable structural space, has a strong pressure-bearing capacity, so the pool can be used as a parking lot, green space, etc.; rainwater storage module can also be combined into a fast drainage channel, to achieve the purpose of the plaza, road drainage.
03 water storage module working principle:
Rainwater falls to the ground, after the initial interception of sewage, flow disposal, retention of rainwater in the larger suspended and floating matter, can prevent the pumps, drainpipes, and other processing equipment clogging. After the rainwater is collected and stored in the modular cistern, the suspended substances in the rainwater (mainly sinkable solids) will be precipitated under the effect of gravity through natural sedimentation, so that the rainwater will be separated and the water will be clarified.
The rainwater stored in the rainwater cistern module can be used for watering roads, replenishing water features, and watering lawns after being filtered and disinfected by other rainwater treatment equipment. Rainwater can also be infiltrated through the cistern to supplement groundwater resources and improve the ecological environment.
04 The role of cisterns in the rainwater collection system
Compared with the traditional concrete cisterns, glass fiber reinforced plastic cisterns, rainwater cistern module has the following advantages:
1, easy to install: rainwater cistern module with a standard modular design, according to the project can be designed into a variety of irregular shapes and sizes. From the fundamental change Conventional pool settlement, cracking, leakage and many other problems.
2, high water storage rate: rainwater storage module has a 95% water storage void rate, and more than 6 tons of compressive strength
3, construction is simple: PP rainwater module can reduce more than 30% of the excavation, transportation, and 60% of the amount of backfill.
4, does not take up valuable space: rainwater storage module installed in the ground, can be set up on demand in the green, roads, squares, parking lots, sports fields Underground, does not take up space on the ground, and will not affect the landscape effect.
5, clean water storage: rainwater into the rainwater storage module before the abandonment of flow, filtration, the module of water to maintain optimal conditions, and there is enough space for aerobic activities. This prevents anaerobic bacteria that affect water quality due to rainwater cessation. And the modules are made of reliable materials that allow rainwater to be stored for long periods of time without deterioration.
Given the above advantages, rainwater storage modules can replace concrete underground cisterns and fiberglass cisterns in most cases. Only in some special environments, the use of water storage module is limited, consider the use of concrete underground cisterns or basements (underground engine room) set up storage tanks
