No matter if new construction or refurbishment - every single adapt-installation is individually adapted and optimized by hydrograv to the conditions of the plant. Regularly with several hundred flow simulations (CFD) per installation. In this way we achieve the maximum benefit for the operation and for the environment: the highest possible performance reserves for secondary treatment with the lowest effluent values of filterable substances (AFS), total phosphorus of the treatment plant and COD.
Already since the first installation more than 10 years ago hydrograv adapt stands for two impressive advantages: More capacity for the secondary clarifiers and at the same time clean water in the outlet. Since 2018 the adapt system has been proving that very good things can also be improved: since then the patent-pending phosphorus elimination ring - PER - ensures that even clearer water flows out of the tanks. Already in use at several plants, for example in Frankenberg/Eder and in Schlüchtern, it has already proven over many months that the total phosphorus in the effluent of a wastewater treatment plant can be reduced to monthly average values of only 0.2 mg/l Pges with the adapt 2.0 system with PER, even without additional filtration.
hydrograv adapt 2.0 with PER solves the AFS problem at its cause - the inlet of the secondary clarification - instead of curing the symptoms with one filtration only, which is expensive and energy and maintenance intensive.
Our robust drive solution ensures that all moving parts under water are driven by a single motor. This motor is freely accessible above the water level. Particular emphasis was put on all details of the construction to ensure that no parts can jam under water. Sufficient play ensures that this has not become a problem in the cumulative well over 200 years of operation of all installations. The maintenance effort has therefore been minimal on all our installations for many years.
Of course, the adapt system can move fully automated to the best position due to the connection to the process control system of the sewage treatment plant at any time.
