  • Information for local authorities

    In contrast to industry and commerce, local authorities municipalities generally have to deal with comparatively readily degradable, albeit fluctuating quantities of waste-water sewage. We offer municipal treatment plants the following innovative, tried and tested proven processes: High performance nitrification

    - with suspended and robust carrier-bound immobilised organisms, - for the main stream, the sludge process water or landfill leachate.

    Anaerobic pre -/ partial treatment pretreatment of effluent sewage in plants with minimised sludge generation.

    Biofiltration of the effluent as after-treatment, using adsorbing, porous carrier surfaces to achieve more stable nitri- fication, remove residual COD, and toxic and suspended substances.

    Enzyme-supported sludge digestion, improved exgestion resulting in, less residual sludge and enhanced sewage gas production,

    Biological waste-gas treatment – for „lightening speed” treatment desodorating within seconds polluted waste- gas emissions from treatment plants, composting plants and waste warehouses compact trickle-bed reactors with BIOCONS carriers for the protection of staff and local residents.

    Among our successful, tried and tested “special tools“ are

    - Highly active special organisms (biocatalysts - patented), adapted to tackle the specific problem which operate far more efficiently and quickly than conventional biosludges. - Porous, absorbing BIOCONS carriers for the IMMOBILISATION of special organisms.

    Our innovative, compact and cost-effective solutions can be configured for the

    - Improvement and expansion upgrading and extension of existing plants and - Construction of new plants.

  • Compact anaerobic-aerobic municipal treatment plants with minimised sludge production

    The problem

    As a by-product, municipal waste-treatment plants generate high quantities of sewage sludge whose disposal is highly cost intensive. However, only around one third is eliminated in today‘s standard sludge-digestion proces- ses.

    Our Idea and Solution

    To avoid high quantities of sludge, the effluent sewage is fermented by methanising the organic contaminants ana- erobically initially through immobilised microorganisms and subsequently aerobically aftertreated. In the process, the contents of effluent are largely eliminated with much lower sludge production.

    Description of Process

    In the first anoxic downstream chamber, the organic content of the effluent is subject to hydrolysis and acidifica-

    tion. From here, the effluent flows into the plant’s anaerobic reactor and then upstream through a layer of immobi- lised anaerobic microorganisms equipped with biomass attached on absorbing, porous BIOCONS carriers which degrade the „broken down“ organic substances by methanisation. The generated biogas is collected in the upper section of the reactor and utilised released into the environment. The anaerobically pre-treated effluent, 65 to 80 percent of whose organic load has already been eliminated, flows through an overflow into the aerobic reactor, which is aerated by means of a special ventilation aeration system installed on the bottom ground. The residual or- ganic contaminants are then oxidised to form carbon dioxide and the ammonium nitrate is nitrified to form nitrate. The denitrification to molecular nitrogen is effected in non-aerated, oxygen-poor anoxic segments of the activated reactor. The excess sludge produced there, comprising generally only 1/5 to 1/4 of the normal amount, is then separated off into a secondary tank and removed from the plant at regular intervals. The advantages of the anaerobic-aerobic process compared with the aerobic variant:

    - Maximum possible elimination performance, with - Higher process stability (through immobilisation) - Higher space-time-yield - Higher elimination performance due to the anaerobic preliminary stage, (AOX, endocrine substances), - approx. 80% less, and better settleable excess sludge, as well as - Lower energy consumption (for aeration and sludge treatment).

    In addition, by virtue of the microorganisms immobilised on BIOCONS carriers considerably more hazardous, endocrine disrupters could be eliminated than in the parallel plant operating with suspended organisms.

  • Construction of new plants for local authorities

    We provide you with technological support in the design of new plants. At the same time, in addition to

    - The determination of water quantities and their pollution load - The bio-degradability of the individual strains single streams, or the entire effluent and their - Seasonal fluctuations, or - Future trends

    must be considered.

    Our objective is the design of

    - Customised - High performance - Cost-efficient - Environmentally and user-friendly plants,

    which can be flexibly adapted to the production requirements or to the expansion of the production plants. The crucial difference compared to the operation of conventional plants can be achieved through the application of BIOCONS carriers.

  • Treatment of complex, poorly-degradable industrial and/or commercial effluent with immobilised microorganisms

    The effluent load of individual industrial sites depends upon their particular type of production. Where as the continual production of paper, paints, food stuffs and mass chemicals (alcohols, carbonic acids, sugar, proteins, etc....) usually generates effluent with readily degradable contaminants, multistage manufacturing plants operating intermittently produce complex effluents, particularly if their products must be

    - durable, i.e. light and washproof (dyes, optical brighteners, etc..) or biologically active (herbicides, phar maceuticals etc..

    which usually contain

    - Several classes of substances of varying chemical structure, properties and degradability (usually poorly degradable), and - high salinity, whereby their - composition and concentration is subject to substantial fluctuations

    Apart from the chemicals industry, such complex effluent is also produced in other industrial sectors, for example in the:

    - Manufacture of chemicals, pulp and paper - Textile finishing and tanneries - Coal refining (coking plants), - Disposal plants (landfills, fermentation and composting plants, the concentrate from emulsion separation plants, sludge treatment, etc.) - Manufacture of petrochemical products

  • Optimisation, expansion and improvement

    Biological treatment plants are designed and constructed on the assumption of fixed in-flows in terms of quanti- ties and contaminants. Changes in production capacities, product ranges and regulatory stipulations can usually prompt changes in the quantity of effluent and its composition, in which the original process parameters no longer match optimal efficiency, leading to an overload of the plant’s capacity and a deterioration of the degradation performance.

    In such cases, the plant need not immediately be expanded, but rather its performance canbe modified to suit the new requirements

    - after careful analysis of the situation, by implementing the - optimal combination of suitable measures,

    which facilitate

    - improvements without large-scale investment, or by implementing - minor expansion measures.

    The “tools“ we deploy for this are:

    - Experimental determination of process parameters - Application of optimised, cultivated microorganisms, whose performance can be considerably enhanced by - Immobilisation on BIOCONS carriers.
