First, the use of long life: This product resistant to moisture, acid, oxidation resistance, no distortion temperature up and down, the normal use of more than 50 years. Second, covers an area of ??small: This product footprint is about 45% of the traditional septic tank, saving land resources, with site selection sensitive properties. Third, the device construction Lunch: free space requirements can be based on a combination of devices, two hours after the device is ready for use. Fourth, high compressive strength: reasonable product structure design, average pressure, repeatedly cycling through 200 test truck is not rolling in the upper part of the settlement, no deformation. Five, low cost: the overall cost is 80% of reinforced concrete construction, urban construction department is trying to implement environmentally friendly products. Six, never leakage: Product barrel body with strength glass fibers, organic resin material forming a high acid and alkali resistance, good sealing, will not produce damage and fracture phenomena pond scum layer compaction due to foundation settlement caused thoroughly dealt with brick septic public water pollution problems and ensure the robustness functioning septic tanks and anaerobic septic function. Seven disposal effect: under split-level design of the product compartment panel, from the DC-style pan of water to the pan of water circulation type, matrix transfer fluent application of anaerobic biological filter (AF) packing system, trapped more more biomass, sewage disposal in order to progress more than doubled in the same volume than conventional septic tank.
