The Amajet system is perfect for automatic cleaning of walls and floors in: Stormwater retention tanks, stormwater overflow basins and stormwater settling basins Storage sewers in sewer systems Fluids handled Water Stormwater Waste water Mixed water Operating data Operating properties Characteristic Value Sizes DN 100 Motor rating P to 16 kw Fluid temperature t Up to +40 C 1) Design details Design Drive Stationary or compact pump set with horizontally or vertically installed submersible motor propulsive jet pump with non-clogging F impeller Three-phase asynchronous motor DOL starting Enclosure: IP68 (permanently submerged) to EN / IEC 529 Thermal class F Motors integrated in explosion-proof pump sets are supplied in Ex d IIB type of protection.

5 Heating sludge Mixed water Raw waste water Raw sludge Recirculated sludge Bearings Grease-packed rolling element bearings Configuration and function Amajet system for cleaning tanks Design KSB's system solution consists of: A robust submersible motor propulsive jet pump with nonclogging free-flow impeller An Amajet ejector set designed for high cleaning performance A control unit, optionally with operating data logging system and data storage unit Level monitoring equipment Control unit Function Amajet sucks in the fluid from near the tank floor and transports it to the ejector nozzle. The narrow passage through the reducing nozzle increases the flow velocity in and downstream of the nozzle, producing a low pressure in the mixing chamber compared to the fluid surrounding it and compared to the atmosphere. Through the vent line this low pressure draws in air, which is mixed with the fluid in the mixing chamber. The fluid-air mixture is ejected through the ejection pipe as a high-velocity jet that is horizontal to the tank floor. The combined effects of the water jet and the small air bubbles in the fluid generate a powerful horizontal flow with a large vertical reach in the tank. The turbulences caused in the entire tank by both transverse and longitudinal flows lift up the solids and keep them suspended. During drainage the sludge is carried out of the tank at an even rate to prevent peak demand periods for biological waste water purification. If the fill level in the tank exceeds 1 metre, the energy-saving intermittent operation mode set to approximately 10 to 50 % of the operating time is sufficient. This mode is designed for cleaning tank walls and posts. At a fill level below approximately 1 metre, the general cleaning mode (i.e. continuous operation) is activated. A control unit with operating data logging system and data storage unit Function SewerAmajet is installed on the sewer floor in the storage area. By means of a suction pipe and ejector it mixes waste water with air and ejects the mixture lengthwise along the bottom of the sewer, thus enriching the waste water with oxygen and preventing digestion. The high-grade cleaning effect of this patented cleaning equipment is achieved by combining a throttle valve with a jet nozzle. The control unit of the storage sewers transmits the required impulses for opening and closing the throttle valve at set intervals. When the valve is partly closed, the pressure increases up to 1.5 times during continuous operation of the pump set. When the valve opens, this energy is suddenly released and produces shock waves, which spread over the entire length of the storage sewer. SewerAmajet for storage sewers can usually be retrofitted without any structural modifications as long as a suitable shaft structure is available for installing SewerAmajet. A single SewerAmajet system can also be used to clean several sewers arranged in parallel, provided that specific conditions are met. Control unit The control unit is precisely set to match the conditions in storage sewer systems and ensures a fully automatic operation of the pump set, taking into account the storage sewer geometry, inflow and discharge conditions as well as the pollution load. Product benefits Energy-saving cleaning mode by intermittent operation matching the actual hydraulic conditions Intelligent control system and perfect automation by process controller: Electronic control units select a matching operating mode for each water level; operating times are computed based on the current water level. Low maintenance Low life cycle costs thanks to low maintenance costs and high energy efficiency Straightforward assembly of ready-made components Control system Optimum operation of the Amajets is provided by KSB's electronic control unit. The parameters for all levels and hystereses needed for automatic operation can be freely set to satisfy all system requirements. Amajet only operates when the water level within the tank decreases, i.e. during the draining process. The operating times for the individual Amajets are calculated separately based on the current water levels.

The reference values given are based on optimum conditions. As project-specific conditions such as fluid composition, internal structures, surfaces, drainage, etc. can have a significant impact we recommend involving us already in the planning phase.
