EMU: Removal Device

During static thickening of treated sludge sludge water will occur, which will have to be transported to the intake of the sewage treatment plant. A special sucking device will do this job. In this construction a submersible sewage pump is installed in the basin upside down by means of a lowering device in such a way that the sludge water can be sucked off during operation. As the water in the basin surrounds the motor of the pump it is always properly cooled. The position of the pump is adapted to the water level in the basin by means of the lowering device. An alternative to the installation with lowering device is to fix the pump with a pontoon on the water surface. This means that the pump automatically adapts to changing water levels and is always ready for operation. This system is also used in SBR-installations for removing clear water. After the sedimen-tation phase the clear water can be pumped off by using the system with pontoon. The removal of floating sludge on final clarification basins is a task that constantly occurs. By installing the lowering device at the scraper bridge the floating sludge can be sucked off and transported to the sludge treatment.

EMU: Submersible Pump

Economical Solutions

For Several decades WILO have been producing submersible pumps for water supply, lowering of water level and booster plants. These highly developed quality products make possible a maintenance-free application. They are a result of many years of experience and intensive development activities and have proved to be worthwhile under teh most difficult conditions.
Due to this comprehensive program of submersible pumps there is a variety of solutions for hydro-economics problems-in the municipal and industrial area.

Application
Besides their traditional applications submersible motor pumps are increasingly installed in sumps, collecting chambers, storage or intermediate reservoirs, lakes dams or rivers for:

• Supply of drinking industrial and emergency water
• As booster pumps in supply networks
• Water treatment plants
• Irrigation and sprinkling
• Circulating purpose in air conditions and industrial cycles
• Fire Fighting and sprinkler systems
• lowering and maintaining of the ground water level in mining and civil engineering
• Use of geothermic energy
  
• fountains and hydraulic organs
• Snow canons
• Off-shore-plants
  

EMU: Switch Gear and Control Panel

WILO EMU Anlagenbau plans, produces and assembles the electrical switch gears and control panels for our submersible clear water and sewage pumps for waterworks and sewage treatment palnts.
Product range:

• Low voltage distributor systems
• remote control and network technique
• control panels
• automatic emergency power control
• alarm systems
• process visualization devices

According to the principle all about water -everything from a single source. we also install our submersible clear water and sewage pumps. For deep wells we supply the necessary rising mains, well head covers, fittings and hydraulic accessories and install the pump. In waterworks and booster plants our mechanics execute the assembly of the complete machinery equipment ready for operation.

EMU: Transport of The Sewage-Drainage Systems

Pressure drainage systems care for the drainage of remote farms, enterprises and settlements. The collected sewage is transported to the public sewer system through EMUPORT underground pumping stations. They are equipped with submersible pumps either in wet or in dry sump installation. You can choose between sumps of PEHD-quality or concrete.
We especially want to mention EMUPORT pumping stations with pumps in dry sump installation and solids separation system in a PEHD-sump.

EMU: Water Supply and Lowering of Water Level With Submersible Pump

Water Supply and Lowering of Water Level With Submersible Pump

Worldwide application
All over the world communities and industries count on WILO submersible pumps for water supply and lowering of water level. their mature technology has proved to be worthwhile in practice a thousand times. The advantages of these type are their slim construction, easy handling and the fact that no maintenance is required. the single or multi-stage centrifugal pumps are directly installed in the pumped liquid. By precisely trimming the impellers it is possible to exactly determine the pumping duty required and so to achieve economical solutions for all pumping problem. These are convincing arguments for the use of WILO submersible Pumps.

Pumping of water
For pumping groundwater out of boreholes WILO submersible motor pumps are graded according to the usual well diameters. The comprehensive range reaches from 4" up to 24" and bigger. These pumps are vertically installed and suspended at the rising main. Installation depth and well productivity determine the pump to be use of suitable materials for a long and maintenance-free pump operation.
In basins, lakes and rivers a horizontal installation is possible without problems.

EMU: EMUPORT Dry Sump Installation

EMUPORT Dry Sump Installation


EMUPORT underground pumping stations
The best possible protection against corrosion is one of the most important demands placed on a pumping station. Therefore materials are used in EMUPORT underground pumping stations which guarantee an optimum operation.
– PEHD climbing aid or stainless-steel ladder with stainless-steel access aid
– all pipelines including union piece of PEHD

– PVC ball valve
– cover of stainless steel or with BEGU class D withstands foot traffic

EMUPORT underground pumping stations with pumps installed in dry sump
The sewage flows into a separate PEHD collection reservoir forming part of the plastic sump. The pump compartment itself stays clean, dry and odor-free. Maintenance and assembly work takes place under hygienic conditions. Additional equipment for these pumping stations suitable for aggressive sewage:

– drainage pump at the bottom of the sump
– barrier is controllable in the sump
– collection reservoir and sump aeration in PEHD tubes; aboveground optionally in stainless steel material
– WILO submersible sewage pumps with single-channel impeller or vortex impeller
– Protection type IP 68 (submersible)

EMU: EMUPORT Solid Separation System

Solid Separation System
EMUPORT-PEHD underground pumping
stations with pumps installed in dry sump and solids separation system
The pumps do not come into contact with the solids in the sewage itself during the pumping process. This results in the following advantages:
– low maintenance and operating costs for moving parts of the pumps
– pump compartment remains dry, clean and odor-free
– hygienic conditions for maintenance and assembly work
– can be equipped as double pumping station; the plant remains fully functional, even when a pump is being serviced

– WILO submersible sewage pumps with suitable impeller
– no corrosion problems, no consequences in case of formation of sulfur
– Application of pumps with ball passage <>
