Waste Water Treatment
Simple and cost effective
A Moving Bed system comprises three chambers. The wastewater enters the first chamber, where all solids sink to the bottom. Floating particles are retained thanks to the overflow openings.
The wastewater enters the second chamber through the overflow openings. Actual biological cleaning by microorganisms occurs here. These microorganisms stick to the carrier material, which is made of plastic. The carrier material has a very large surface. The bacteria needed for purification sticks to the carrier material such as a ‘bio film’.
So that the bacteria receives enough oxygen to breathe, the Moving Bed is regularly streamed with air. An air compressor is used for this purpose, which is installed in the cellar or in the garden outside the reservoir.
Then the wastewater enters the third chamber for final treatment. The remaining solids settle there and they are pumped back to the first chamber from here. The purified wastewater can now be fed into a discharge system or infiltration system.
| Waste water treatment refers to the filtration process of used and dirty sewage water. Waste water treatment helps in wiping out all the harmful constituents present in the sewage water. This treatment is mainly carried out in the waste and water driven out from the housing complexes, offices, hospitals, institutions and even industries. This waste water mainly comes out from the bathrooms, toilets, showers, kitchens and sinks etc.
This process is a combination of several chemical, physical and biological processes. It is basically a recycling process of waste and contaminated water. This treated water can be used for watering plants, cleaning and flushing toilets as well as other agricultural purposes. This treatment process is a very long process which mainly consists of pre-treatment process which destroys the solid wastes present in the sewage water thus preventing the blocking of pumps and other pipes. The screening process involves removing all sorts of hard materials like the cans, sticks, wood etc present in the sewage water with the help of automatic mechanical raked bar screen system. The sedimentation process helps in cleaning the water from the floating oil and grease and thus creates liquid which can be biologically treated. The sedimentation process mainly consists of settling tanks which are installed with mechanically driven scrapers which constantly remove the sludge into the sludge treatment system. The secondary treatment process disintegrates the biological wastes present in the sewage water. The biological wastes mainly consist of human and animal wastes, detergent and soap wastes. This biological process is an aerobic process which means this process is carried out with the help of oxygen. There also exist membrane bio reactors which use high and low pressure technology to wipe out the dirty content in water. |
