Wastewater Treatment
Chemical tanks
Water and Wastewater
Through the addition of chemicals, phosphates in the wastewater are precipitated out, for example in primary sedimentation, in aeration systems or in special precipitation and secondary clarifiers. Pr...
Coarse and fine screens
Water and Wastewater
Mechanical cleaning removes entrained floating matter with screens or sieves. This protects the downstream process stages from buildup, clogging and abrasion. Solids with diameters greater than 25 mm...
Combined Sewer Overflow (CSO)
Water and Wastewater
Large Combined Sewer Overflows (CSOs) protect the wastewater treatment plant from a capacity overload during heavy rain. The precipitation is temporarily stored and then delivered to the treatment pla...
Conditioning
Water and Wastewater
The applied chemicals and precipitants are suitably conditioned to ensure that they reach the wastewater in an optimal, low concentration. They are metered out according to the degree of pollution and...
Container
Water and Wastewater
After coarse/fine screening, sorted solids such as waste, plastics, sand and sludge are transported to special containers via conveyor belt. Reliable level measurement enables automatic notification t...
Digester
Water and Wastewater
The organic components of sewage sludge are decomposed under anaerobic conditions in heated, closed digestion tanks. In the process, combustible gases such as methane are released from the sludge. The...
Fuel tank
Water and Wastewater
Backup generators are a common safeguard at lift stations to maintain operation during power outages. Day tanks at each lift station and a main tank at the plant are used to store the fuel. To make su...
Gas pipeline
Water and Wastewater
The biogas generated from sewage sludge is used for environmentally friendly production of heat and electricity. It is transported to the storage tanks through a gas pipeline.
Gauge station
Water and Wastewater
Accurate monitoring of the river level is an important prerequisite to be able to react quickly and correctly in the event of a flood. Data recording and transmission via radio link is the optimal sol...
Grit trap
Water and Wastewater
Through circulation and aeration of the wastewater, mineral substances such as grit and sand settle to the bottom of the settling basin. Point level detection of settled sand under water prevents equi...
Grit washer
Water and Wastewater
Before the settled out sand can be used as recycled material, it is cleansed of organic matter in the sand washing plant. The washed sand is then dewatered in a screw press and discharged into a stora...
Gullies
Water and Wastewater
Buildup and deposits accumulate in gullies and raise the water level there. Since this can lead to blockages, gullies must be cleaned regularly. Reliable level measurement ensures that blockages are r...
Inlet channel
Water and Wastewater
Sewage and rainwater are often transported to the treatment plant in open collection channels or flumes. The flow rate is measured at various points in these channels. Measurement of the water flow at...
Lime silo
Water and Wastewater
In the nitrogen and phosphorus removal stage, lime is used to stabilize the pH value. Stored in silos, the lime is added to the wastewater as a solid or as an aqueous suspension. The silo content is m...
Mixing and equalization ponds
Water and Wastewater
These open pools even out peak loads and strong volume fluctuations. During periods of decreased load, the wastewater is pumped from the buffer pool into downstream biological treatment basins. A lev...
Process water tank
Water and Wastewater
The process water is collected in tanks or open basins. Pressure pumps deliver the water for cleaning and rinsing purposes to various locations in the wastewater treatment plant. To ensure an optimal...
Pump room
Water and Wastewater
To protect the process pumps, any leakage water, e.g. arising from a faulty pump seal, is detected and an alarm triggered. The pressure in the pipe is measured directly at the pump and displayed in th...
Pumping station
Water and Wastewater
Wastewater from households and businesses, together with surface water, is carried to the wastewater treatment plant via an extensive sewer network. If the natural gradient is not steep enough, numero...
Receiving watercourse
Water and Wastewater
After the wastewater has been treated, it is discharged into bodies of water through a drainage system. The local municiple water organisation requires measurement of the amount of wastewater being di...
Sewage screw lifting station
Water and Wastewater
The heavily soiled, greasy wastewater from households and commercial enterprises flows into the sewage lifting station. The dirty water and floating debris contained therein are raised to a higher lev...
Sewer network
Water and Wastewater
Wastewater from households and industrial operations is carried through a sewerage system to the clarification plant. In large sewer systems, the water levels are monitored at key points in the networ...
Sludge dewatering
Water and Wastewater
The digested sludge is dewatered prior to drying in centrifuges or filter presses. The sludge liquor thus obtained passes through the cleaning process of the WWTP once again. A level detector controls...
Sludge drying
Water and Wastewater
Through drying, the weight and volume of the sludge is further reduced. In the thermal drying unit, which is equipped with a belt drier and a hot (+80 to +130 °C) air stream, water is removed from the...
Sludge granulate silo
Water and Wastewater
After thermal drying, the sludge is stored in silos for further use. The granulated product is deposed of in landfills, used in agriculture or burned for energy generation. The level measurement and p...
Sludge receiving station
Water and Wastewater
Sewage sludge from small decentralized sewage treatment plants or sewer cleaning operations is delivered in special vehicles. It is collected in a receiving tank and then gradually fed into the main s...
Sludge storage tank
Water and Wastewater
The digested sewage sludge is pumped into a sludge storage tank. This tank serves as an intermediate storage facility before the sludge is fed to the centrifuge or pressed for mechanical dewatering. T...
Sludge thickening tank
Water and Wastewater
Before the sludge enters the digestion tower, it is stored in large vessels. During storage, the sludge is dewatered and thickened sometimes scrapers and agitators are used to accelerate the process.
Stormwater retention basin
Water and Wastewater
In case of heavy precipitation, excess rainwater is temporarily stored in open, artificial reservoirs. The water reservoir buffers the drainage and the water is pre-cleaned through natural settlement....
Vacuum sewerage system
Water and Wastewater
When new building zones are opened up, it is often quite expensive to build a sewerage network with the necessary downward slope. In such cases, a vacuum sewerage network offers an interesting alterna...
Biogas storage facility
Water and Wastewater
The methane gas extracted from the digestion tank is temporarily stored in a gas reservoir. Depending on the design of the gas storage facility, either a flexible diaphragm of plastic or a floating ro...
