New Solids Separation System for Highly Efficient Waste Water Disposal


At this year’s IFAT, KSB Aktiengesellschaft, Frankenthal, Germany, will present an innovative solids separation system allowing highly efficient waste water disposal in pumped drainage applications.

New Solids Separation System for Highly Efficient Waste Water Disposal

The new AmaDS³ system for waste water transport applications excels through its economic efficiency and operating reliability.

New AmaDS³ is a technically advanced system for waste water transport which excels through its economic efficiency and operating reliability. It is a combination of a patented, dry-installed solids separation system and two waste water pumps in back pull-out design.

The raw waste waters flows into a separator where the solids are separated from the liquid. Then the solids-free waste water flows into a collecting tank where it is collected until a pre-set level is reached. The pump set is started up via a control system and pumps the waste water from the collecting tank into the discharge line. During this operation, the solids are flushed out of the separator and into the discharge pipe as well. The pump set is switched off once the waste water level in the collecting tank has gone down to the pre-set minimum level. At this point the inflow check valve opens automatically and raw sewage can again flow into the separator.

As the waste water handled by the pump s hydraulic system is mechanically treated, pumps with smaller free passages and highly efficient hydraulic systems can be used. This enables operators to achieve considerable energy savings and to keep operating costs down. Even in the case of high heads or long discharge lines AmaDS³ is a viable solution for economically efficient transport of raw waste water. In addition, the service life of the entire station is longer than that of conventional systems. Since the pumps handle solids-free water only, the risk of wear and clogging is extremely low.

All main components are redundant. The pumps as well as the system’s most important components can be reached comfortably and without getting wet. The separators are located outside the collecting tank. This ensures that the system can be serviced or repaired while it is in operation. The collecting tank is gas-tight and features a central vent. New AmaDS³ is available in six different sizes. Its maximum head is 85 metres and the maximum inflow rate 120 cubic metres per hour.
