Abstract: A bioremediation device for liquid waste includes a medium for forming a microbial film and for exposing the microbial film to an effluent to decompose a first substance in the effluent and to produce a second substance from the decomposition of first substance. An aerator is coupled to the medium to supply the microbial film with oxygen and to accelerate the effluent around the microbial film.

Abstract: One embodiment to assist bioremediation in grease intercepters to substantially reduce FOG (fats, oils and grease) commonly installed in Food Service Establishments. The embodiment consists of a open elongated enclosure (28) containing a media basket (22) positioned in an pneumatically accelerated flow generated by a aeration lateral (26) located towards the bottom of the device. The embodiment is inserted into existing grease interceptors and rests submerged at the bottom of the grease vault. It only requires a constant air supply via a readily available air pump. The airflow moves the liquid to the media, providing the oxygen for the biofilm around the media tubes (20). The biological processes of the biofilm results in the reduction of FOG. The effectiveness of the systems depends on the regular introduction of microbes. Alternatively the embodiment can be used in animal waste lagoons, septic systems, waste water treatment basins etc.

Abstract: The invention relates to a method for charging for Internet services, wherein the Internet users have access to the Internet via servers of an Internet provider and use the fee-paying services of various providers. According to said method the Internet provider refers the Internet users to pre-established providers. When a service is ordered by an Internet user from a pre-established provider, an order ID is issued by the computer of the user and said order ID is transmitted to the service provider and the Internet provider, thereby enabling anonymous use of services and ensuring a secure charging method.

Abstract: The invention relates to a method for processing a payment operation via a credit card financial service provider in electronic commerce in an open network, particularly on the Internet, between a purchaser and a trader, where the credit card financial service provider transmits a transaction code which is valid for one payment operation to the purchaser at the latter's request, and the purchaser uses this transaction code instead of his credit card number when processing the payment operation with the traders.
