GEOIMPULS Sewage Plants
The life of humans, of animals and plants is a natural recurring cycle where large varieties of different materials are continuously transformed and recycled. This material cycle is the basis for the regeneration of our main resources, such as soil, water and air. Often this cycle is not accessible for whole communities. The availability of wastewater treatment plants for example is not taken for granted for millions of people. Sanitary problems caused by bad or non-existent sewage systems are the reason for diseases and spreading epidemics. Immeasurable economical damage is caused each year. Besides this, organic materials produced by millions of people are not recycled and brought back into the soil where they belong to regenerate soil fertility and add organic matter. Instead, water not cleaned from faeces pollutes rivers and lakes, contributing to the reduction of fish populations and diminishing drinking water resources. As consequence of this wastefulness, agricultural soils have to be fertilised mainly with expensive chemical fertilizers to compensate for the lack of natural nutrition. Paradoxically, this nutrition exists abundantly, but it is not used since material cycles are not closed. High dosages of chemical fertilizers pollute ground water sources and equally bad, the growing of crops is not balanced anymore, requiring higher inputs of pesticides. Because of the destruction of resources caused by irresponsible water cycles, the quality of life of each individual and the energy he has available for his work and creativity is badly depleted.
But this need not be. We wish to present a simple but extremely effective system for the treatment of wastewater. This system does neither need expensive construction measures, nor elaborate operational intervention or maintenance. It does not use expensive filtering elements. While nobody has control over sudden rainfalls or flooding during the monsoon, this system responds appropriately to emergency flooding.
GEOIMPULS Wastewater Treatment Plants – with floating pond aeration system
The floating pond aeration system of GEOIMPULS uses the principle of Sequent Batch Reactor (SBR) Technology, combined with traditional wastewater pond principles and operational control systems. This unique combination offers a variety of synergies, which is especially appreciated by the specialists in the cleaning of communal wastewater, as well as in the industrial sectors, outside the chemical industry.
Through the combination with a specially developed floating pond aeration technology, the traditional wastewater pond is optimized. Simultaneously, its advantages with respect to safety of operations, buffer zone for sudden rainfalls, simplicity of operational processes and especially its reduced costs of construction fully come to fruition.
This wastewater treatment concept differs from other systems through its pulsating batches of continuous inflows and discontinuous outflows into one pond. Based on this pulsating rhythm an extremely precise cleansing effect is achieved, whilst at the same time the continuous inflow does not cause operational interruptions.
Other synergies are achieved through the combination of the traditional pond concept with state-of-the-art SBR & aeration technologies. These comprise amongst others the following:
Safety of Operations under Peak Loads
Because of the large capacity of the plant, operational safety is greatly enhanced. This allows to “thin down” or to dilute peak loads coming from sudden rainfalls as for example during the monsoon period and to get these more efficiently integrated with the bio mass. This dilution effect also takes place with loads of toxic substances such as from industrial activities. For example in-flows of contaminants from industrial complexes, attached to the wastewater system, would in the extreme case, cause much less damages than habitual plants and would also be much easier to rectify.
This offers a high degree of reliability, which the technical departments of urban communities greatly appreciate.
Buffer Effect for Sudden Rainfalls
Because of its unique way of construction, the wastewater plant is capable to absorb a larger quantity of water and to store it. The absorption of the so called ” initial flush” from sudden rainfalls is possible through the barrage effect of the pond. Rainwater retention ponds are therefore not needed, since the latter are replaced by the high hydraulic absorption capacity of the pond itself. This not only avoids incremental costs of construction, but also continuously incurring expenses for cleaning sediments in the water retention ponds, nuisance caused by bad smell plus many hygienic problems.
Efficient Aeration, Increased Cleansing Efficiency & Optimal Thermal Conditions
Due to the extensive volume of the pond, lower bacterial population levels are reached. This facilitates aeration of the pond and the exchange of gas. Bacterial density is a factor of the programming of the plant and its in-flow volumes and may comprise 1 – 2 gram of biomass per litre. At the same time, a more natural exchange of air is accomplished which may be considered as auxiliary, cost free aeration across the pond’s large surface. Due to the pond’s relatively shallow construction type, resulting in a bed of approximately 2,50 m in depth, arriving air does not need to be largely compressed. This greatly safes energy and water is less heated through compressed air, which is a great advantage in tropical zones where, caused by the weather, high water temperatures frequently occur.
Cost Effective Ponds with Plastic Skin
On one hand caused by the marginal depth of the pond, on the other hand by the possibility to erect the pond with plastic skins, a considerable cost saving is achieved. Apart from this, ponds created with plastic skins are much more flexible when it comes to rectifying cracks, tensions and displacements in sub layers than equivalent constructions in concrete. This, therefore, allows the cost efficient construction of wastewater plants in rural areas.
Reduced Stirring Mechanism’ Output through Moving Aeration System
Due to it’s floating and moving aeration system a torrent or a wall of water is created, sowly moving back and forth through the water. This prevents biomass from sedimentation. This means a considerable reduction in the use of additional stirring mechanisms.
Repair & Maintenance Works
Since the GeoImpuls Sewage System operates with floating components, repair & maintenance jobs are considerably facilitated. In such a case the sewage plant may continue its operations without interruption, even during repair and maintenance sessions. There is no need to let off the water, not even in situations where the replacement of complete components will take place.
Better cleaning of phosphorus
The rate of elimination of phosphorus by the plant is higher than with habitual waste water systems. Because of the efficient and strong aeration in combination with a lower density of biomass, microorganisms are capable to bind more phosphorous, thus protecting subsequent water resources.
Improved Fertilizer Quality through Increased levels of Phosphorous in the Sludge
The efficiency of the sludge as fertilizer is enhanced because of an increased content of orthophosphate and other phosphorous forms. The commercial value of the fertilizer product sourced from sludge is increased.
Reduction of Smell
Depending on national laws and regulations the use of sedimentation ponds can be abstained from. Apart from additional cost savings, disturbances through bad smells may be reduced, since anaerobic processes, taking place in sedimentation tanks, can be avoided.
Following pre-cleansing through sieves, the entire wastewater flows into the aeration pond where it will be exposed to very strong oxidation.
Through benefiting from the synergies of two different, apparently opposing systems, the GEOIMPULS wastewater treatment plant system offers the possibility to treat and clean wastewater cost efficiently and globally on highest quality levels.
