2. Hybrid biological membrane reactor for the treatment of urban and industrial wastewater

Juan Manuel Garrido, Ramón MëndezPampín, VinkaOyanedelBasaez(2006)

This invention refers to a hybrid biological membrane reactor for the treatment of industrial and urban waste water with organic and nitrogenous matter. It is constituted of three chambers: anoxic, aerobic and membrane filtration chambers (Figure 1). The proposed reactor is a compact system with which very low or negligible levels of solids in suspension in the purified effluent are obtained. The present invention implies improvements in the waste water biological treatment systems, in general, and hybrid reactors in particular. One of the main features of the hybrid reactor proposed is that of confining particles of a plastic granular support in the aerobic chamber, having a density slightly less than that of the water. This support neither breaks nor deteriorates by use in the system; furthermore, if will not break due to growth of the biomass therein, as can occur in systems using microorganisms immobilized in the polymeric gels, since the growth is limited to the surface of the plastic support.

The assembly of membrane filtration units in the hybrid reactor makes it possible to obtain an effluent with low levels of solids in suspension, which would comply with the most demanding dumping requirements of this pollutant, significantly decreases the dumping of microorganisms with the effluent (including pathogens and other health vectors); furthermore, it is suitable for dumping close to marine culture areas or fish hatcheries and collection areas for collecting waters used for irrigation or for producing drinking water. At this moment a 3.8 m3 pilot plant is being operated for treating hospitality wastewater (Figure 2) with the participation of the Galician company “Espina Obras Hidráulicas” in the frame of the Interconnecta project “Demagua”. A First option patent agreement was assigned between the USC and this Company

6. Process for the removal of pharmaceutical products present in wastewater (SeMPAC) Francisco Omil, Denisse Serrano, Sonia Suárez, Juan M. Lema (2013)

Technical Field of the Invention

The present invention relates to a process for the removal of contaminating pharmaceutical products present in wastewater in trace concentrations by means of adding powdered activated carbon in a sequential bioreactor coupled to a contiguous chamber containing an ultrafiltration membrane.

State of the Art

Pharmaceutical compounds are a group of organic pollutants with a large number of active ingredients that are consumed on a massive scale in developed societies. These substances are used in the formulation of pharmacological products as well as personal care products (shampoos, body lotions, sunscreens, etc.), therefore covering a wide spectrum concerning the molecular structure, physicochemical properties, biodegradability potential and persistence. Thousands of active ingredients are being used today for synthesizing an even larger number of products. Taking the scope of the EU as an example, more than 3000 different substances are being used in human medicine alone, to which a very significant number of drugs for veterinary use must be added. In terms of the prospects for upcoming years, an increase in medicament consumption is envisaged primarily due to gradual population aging, although it may also be due to the improvement in the quality of life. Legislative regulation of these substances in the environment is imminent, as indicated in the Water Framework Directive (2000/60/EC). In this sense, a list of priority pollutants is updated every four years which already includes several pharmaceutical compounds.

In the present invention, the process proposes using a sequential bioreactor operated under nitrification-denitrification conditions in the presence of PAC, coupled to a chamber containing an ultrafiltration membrane which, as a whole, entails a very efficient process for the removal of pharmaceutical compounds. The removal of those compounds that are more biodegradable is favored by operating under nitrification-denitrification conditions, with high biomass concentrations and long SRTs, whereas the presence of PAC allows removal by adsorption of the more persistent trace pollutants (e.g., carbamazepine), and finally, sorption of the more lipophilic substances (e.g., musk fragrances) on the sludge will increase due to the development of agglomerates (flocs) that are smaller than those growing in a CAS due to the presence of the ultrafiltration membrane. Furthermore, since it is a process with membranes, the retention of the PAC and of the sludge, and therefore of the sorbed compounds, is complete

9. ELAN®Technology: Method for starting up and controlling a biological process for ammonium removal by the action of autotrophic bacteria in wastewater José Ramón VazquezPadín, Roberto Fernández González, Jose Luis Campos Gómez, Anuska Mosquera Corral, Ramón Méndez Pampín(2014)

The present invention is related to a method for starting up and controlling a biological process for removing nitrogen contained in wastewater through a combined stage of nitrification and anaerobic oxidation of ammonium ion (Anammox), in which an aerobic reaction of partial nitrification of the ammonium contained in the wastewater to nitrite with oxidizing bacteria and addition of oxygen, and a nitrogen production anoxic reaction with ammonium and nitrite autotrophic denitrifying bacteria, of the phylum Planctomycetes, take place at the same time, both bacterial populations being arranged in the form of biofilm in the same reactor such that the oxidizing bacteria are on theoutside of the

biofilm contacting an aerobic zone inside the reactor and the autotrophic bacteria are inside the biofilm creating an anoxic zone, characterized in that the reactor is fed with a wastewater flow and air/oxygen are injected into the same continuously until its shutdown, i.e. aeration is facilitated in the entire reaction stage, keeping the dose of dissolved oxygen in the reactor at a level higher than 0.6 mg/l.In order to ensure the stability of the process, the air/oxygen supply to the reactor, the hydraulic residence time and the alkalinity in the feed are controlled such that the (Alkalinityinput-Alkalinityoutput)/ (Conductivity input-Conductivityoutput) ratio must be kept, ideally, below 13 mM/(mS/cm 25ºC). In order to maintain a high efficiency of the process, the alkalinity at the output of the reactor must be between 5% and 25% of the alkalinity at the input.

The present invention belongs to the area of treatment of wastewater having a biodegradable organic matter/ nitrogen ratio lower than 2 kg biodegradable COD/kg N. These waters are characterized by high nitrogen content, such as discharges and wastewater, especially waters and urban discharges treated in wastewater treatment plants (WWTP), and more especially the liquid effluent from anaerobic digesters of the WWTPs, having a high concentration of ammonium as a result of said fermentation process. An example of a current that can be treated through this invention is the drainage of the digested sludge dehydration system in a sludge line of a WWTP.
