    INDUSTRIAL AND DOMESTIC WASTEWATER TREATMENT

    When creating our technologies a key criteria was to avoid any impact of noise, vibration, odor or aerosol on the environment. In line with international practice, this ensures that communal wastewater treatment plants are built in the direct vicinity of residential areas, and industrial wastewater treatment plants are built in factories side-by-side with production units. All this offers significant savings potential. Our biotechnology features a high level of flexibility and toleration capacity which allows high level of automation. A minimum number of operating staff is needed (they can even be employed part-time). The wastewater treatment plants operate non-stop and their professional and effective operation poses an even greater challenge than their construction. Upon demand, our company provides professional supervision and, in case of industrial facilities, comprehensive operation.

    Industrial wastewater treatment plants

    Our industrial wastewater treatment plants evolve in line with the increasingly diverse requirements of our clients and the challenging composition of wastewaters. Competition is extremely intense in this worldwide sector meaning that new technologies must be developed constantly. Our mission is the implementation of patented cutting-edge technologies and their adaptation to a specific task.

    The economic and sustainability aspects of industrial wastewater treatment plants are now among the most important issues. Our facilities employ state-of-the–art low-sludge technologies with typically low space requirements, high flexibility and a level of automation. This allows easy adaptation to hectically changing loads. It is likely that these factors together account for our outstanding success in the industrial segment.

    Industrial wastewater treatment plants

    Domestic wastewater treatment plants

    When developing our municipal wastewater treatment facilities we have followed similar principles to those applied in the industrial segment. Our patented technologies offer the most modern solutions in terms of efficiency, security of operation and operating costs. We recommend our tailor-made, simple biological wastewater treatment plants to any size of municipality.

    The technologies used can be of continuous operation or they can be based on cyclic CONTISEQTM activated sludge technology. At the lower end of the capacity spectrum we can deliver containerised, ready-built wastewater treatment facilities requiring assembly only.

    Biogas

    The sludge generated during wastewater treatment, alongside with a wide range of other agricultural by-products, can be the basis of long-reaching and environmentally aware thinking. The harmonised, coherent development of wastewater treatment, sludge management and biogas production technologies can yield far more economical environmental systems and far greater benefits to the environment.

    On the basis of our experience from a large number of industrial and municipal wastewater treatment projects, both as developer and as main contractor, we can also develop and build cost-effective biogas facilities. Like our wastewater treatment plants, our biogas plants come with a high level of professionalism, which means the best available technologies are delivered.

    INWAFERM innovative digestion

    Concept

    INWAFERM is an innovative digester type of attractively low investment and operational costs, yet allowing the application of the most versatile feedstock. Inwatech constructs flat type digesters facilitating the digestion of feedstock with very high thickness and organic content. Important parts of the INWAFERM concept are:

    • Cost-effective, low energy demand tank mixing and heating system, outstanding heat balance
    • Integrated biological biogas treatment for H2S removal with polishing step BIOGINWA
    • Integrated variable volume biogas buffer at the top of the reactor

    We apply proven, self-developed components including Inwatech’s state of the art control equipment which is easy to integrate into existing systems. Our past experience also covers all necessary equipment to treat and convert biogas into energy, in whatever form it is required (electricity, heat, bio methane, steam). Inwatech’s digesters are also well suited for fermentation of sewage sludge.

    Flexibility

    INWAFERM’s customers come from various agricultural sectors as well as from industries and municipalities that require the utilisation of the widest variety of bio solids and sludge. INWAFERM’s clever design layout and the applied equipment provides excellent robustness, technological safety and flexibility.

    Innovative water disinfection

    Water disinfection by chemicals is steadily losing its popularity due to the disinfectants being harmful to human health and the environment. Not even mentioning that in cases of industrial use, traditional methods are often ineffective. The unique h2o.TITANIUM® offers an effective, chemical-free, up-to-date water treatment solution. The equipment operating on the principle of photocatalysis (UV/TiO2) is suitable for the treatment of drinking, bathing and industrial (waste) water. With the use of h2o.TITANIUM®, the removal of microorganisms and pathogens is faster and more efficient than with any other known and industrially used oxidation technology.

    The use of h2o.TITANIUM® is a reasonable investment since the easy-to-operate, safe and environmentally friendly device has long life, low power consumption and does not require significant maintenance. Furthermore, the photocatalytic technology is available both on its own, and as part of the complex water management system. In special cases, such as an unforeseen microbiological water pollution, the operational leasing of the equipment is possible.

    Summary

    Summary

    The number of green energy investments has been shown a growing tendency both worldwide and in Hungary in the last decays. One important pillar of renewable energy utilization is biogas production which both in Hungary and Norway has come to the fore and become a supported investment as a green technology.

    Biogas technologies based on agricultural input or sewage water have an important but not (effectively) solved aspect: utilization of the by-product digestate on cultivable land meets several problems despite the digestate having an excellent composition for sustaining/increasing the multifunctionality of soils. For example, the high volume of liquid phase digestate results in difficulties at its agricultural disposition, generating relatively high costs; remarkable part of the valuable nutrients can be volatilized and degraded during the digestate treatment; the water soluble plant nutrients can leach into the deeper soil layers thus hampering the nutrient utilization of plants.

    The main goal of this project is to solve the above mentioned problems in the frame of international R&D cooperation on the field of waste management. The result of the project will be a product prepared from biogas digestate, a non-hazardous waste for sustaining/increasing the multifunctionality of soils and the nutrient supply of plants. The raw materials used for product preparation will be bentonite rock as a mineral and biogas digestate as an organic matter.
