Pre Treatment

The quality of surface water in Jakarta is on a serious polluted status. In order to reduce the Water Treatment processing load, a pre-treatment process is needed to eliminate parameters such as organic matter, ammonia, color, taste, and odor. This treatment generally uses chemical and physical processes, such as chlorination and activated carbon that produce harmful byproducts. Moving Bed Biofilm Reactor (MBBR) is one of the solutions developed to reduce the nutrient and organic levels in raw water. This study aims to improve the quality of raw water, by reducing the concentration of COD, NH3-N, Phosphate, and TSS before entering the conventional process. Reactor performance is assessed based on contaminant removal efficiency with variation of residence time (1 hour, 1.5 hours, 2 hours). The reactor is operated by using Kaldness K1 as the medium and oxygen supply of 7 L/min. The optimum residence time is 1,5 hours with the ability to remove COD, NH3-N, Phosphate, TSS 51.8% ± 0.2; 54.3% ± 0.28; 52.6% ± 0.19; and 77.7% ± 0.14 respectively. Based on the optimum residence time, the kinetics of the ammonia removal rate in MBBR takes place at zero order, with a rate constant removal of 0.0056 g/m2.day. The results showed that the higher concentration of ammonia, and organic contaminants treated, the higher the efficiency of MBBR. Apart from water quality improvement, pre-treatment process using MBBR can reduce coagulant dose from 50 mg/L to 9 mg/L, to decrease raw water turbidity from 135 NTU to 0.68 NTU before entering the coagulation-flocculation unit.

A new moving bed biofilm reactor has been developed in Norway. The biomass is attached to carrier elements that move freely along with the water in the reactor. It is demonstrated in the paper that this results in a very compact reactor and a very efficient biomass. Experiences from pilot and full-scale testing of the reactor in municipal and industrial wastewater treatment applications are presented and discussed.

Abstract An aerobic moving bed biofilm reactor (MBBR) was applied to treat landfill leachate generated from a domestic waste incineration plant. Pollutant removal efficiency of this reactor under stable operating condition was studied. The biomass, bacteria species, and microbial metabolism in this reactor were investigated. These results showed that the average removal efficiency of chemical oxygen demand (COD) and ammonia nitrogen in the aerobic MBBR achieved 64% and 97% in the optimum conditions, respectively. The three-dimensional fluorescence spectrum revealed that the content of soluble microbial byproducts from extracellular polymeric substances extraction in suspended sludge was much higher than that on biofilm, and the types of pollutants were various in different regions of the reactor. It also indicated that the MBBR system had a stable, rich and regular microorganism community, including large amounts of nitrifying bacteria and denitrifying bacteria. Scanning electron microscopy suggested that biofilm attached to the packing provided a good anoxic–aerobic micro environment system to achieve a high metabolic activity, which favored COD and ammonia removal.
