The wastewater treatment plants are supplied as complete products including the lid. The blower and control unit are installed inside the plant. TOPAS S WWTPs are made of polypropolene material, which ensures the long life of the product.
Steel-plastic tanks, specifically designed by Greener Waste Technology, are used for larger, rectangular types of plants. In the production we combine profiled steel sheets and thermoplastic, taking advantage of both types of materials.
The tanks are manufactured by welding segments of a sandwich panel. Their main advatnages are:
- Guaranteed water tight tank
- Excellent thermal insullation
- Long term working life without corrosion
- Resistance against chemical substances
- Static (structural) analysis with guaranteed values
All types of tanks can be installed without any structural changes below the groundwater level.
Large underground tanks are installed on a concrete slab. The smaller tanks only need a sand bed as the design does not require concrete walls.
The technological design of the TOPAS S WWTPs is protected by an international patent.
