Control Authority

In 1988 the State Pollution Control Authority in Norway made recommendations regarding process designs for small wastewater treatment plants. Amongst these were recommendations for biological/chemical plants where biofilm reactors were used in combination with pretreatment in large septic tanks and chemical post treatment. At the same time the socalled “moving bed biofilm reactor” (MBBR) was developed by a Norwegian company. In this paper, experiences from a small wastewater treatment plant, based on the MBBR and on the recommendations mentioned, will be presented.

Oxidation Surface

Two methods of surface modification of polyethylene biocarriers, chemical oxidation-surface covering with ferric ion (CO-SCFe) and chemical oxidation-surface grafting with gelatin (CO-SGG), were studied for improving the efficiency of wastewater treatment by moving-bed biofilm reactors. The results showed that two surface modifications caused corrosion pits to increase surface roughness, and brought –(C=O)–/–O–C–O– groups and ferric ions to the biocarrier surface, respectively. The positively charged surface increased the hydrophilicity and biological affinity of the biocarrier. The biofilm formation rate was improved by 37.5 and 60% after surface modifications of CO-SCFe and CO-SGG; the concentration of biomass on the biocarriers was improved by 54.8 and 76.1% and the COD removal efficiencies were increased by 10.63 and 8.64%, respectively. Polymerase chain reaction-denaturing gradient gel electrophoresis analysis showed that the microbial populations in the biofilm were almost the same after surface modifications, but the biomass concentration was greatly increased.

Total Residence Time

Many cities around the world are looking for compact wastewater treatment alternatives since space for treatment plants is becoming scarce. In this paper development of a new compact, high-rate treatment concept with results from experiments in lab-scale and pilot-scale are presented. The idea behind the treatment concept is that coagulation/floc separation may be used to separate suspended and colloidal matter (resulting in >70% organic matter removal in normal wastewater) while a high-rate biofilm process (based on Moving Bed™ biofilm reactors) may be used for removing low molecular weight, easily biodegradable, soluble organic matter. By using flotation for floc/biomass separation, the total residence time for a plant according to this concept will normally be <1 hour. A cationic polymer combined with iron is used as coagulant at low dosages (i.e. 1–2mg polymer/l, 5–10mg Fe/l) resulting in low sludge production (compared to conventional chemical treatment) and sufficient P-removal.

Start Up

Tourists visiting mountain refuges in the Alps have increased significantly in the last decade and the number of refuges and huts at high altitude too. In this research the results of an intensive monitoring of a wastewater treatment plant (WWTP) for a tourist mountain refuge located at 2,981 m a.s.l. are described. Two biofilm reactors were adopted: (a) a Moving Bed Biofilm Reactor (MBBR); (b) a submerged Fixed Bed Biofilm Reactor (FBBR). The aims of this research were: (i) the evaluation of the main parameters characterising the processes and involved in the design of the wastewater plants, in order to compare advantages and disadvantages of the two tested alternatives; (ii) the acquisition of an adequate knowledge of the problems connected with the wastewater treatment in alpine refuges. The main results have been: (i) a quick start-up of the biological reactors obtainable thanks to a pre-colonization before the transportation of the plastic carriers to the refuge at the beginning of the tourist season; (ii) low volume and area requirement; (iii) significantly higher removal efficiency compared to other fixed biomass systems, such as trickling filters, but the energy consumption is higher.
