Oxidation Reduction Potential

On-line control of the biological treatment process is an innovative tool to cope with variable concentrations of chemical oxygen demand and nutrients in industrial wastewater. In the present study we implemented a simple dynamic control strategy for nutrient-removal in a sequencing batch reactor (SBR) treating variable tank truck cleaning wastewater. The control system was based on derived signals from two low-cost and robust sensors that are very common in activated sludge plants, i.e. oxidation reduction potential (ORP) and dissolved oxygen. The amount of wastewater fed during anoxic filling phases, and the number of filling phases in the SBR cycle, were determined by the appearance of the ‘nitrate knee’ in the profile of the ORP. The phase length of the subsequent aerobic phases was controlled by the oxygen uptake rate measured online in the reactor. As a result, the sludge loading rate (F/M ratio), the volume exchange rate and the SBR cycle length adapted dynamically to the activity of the activated sludge and the actual characteristics of the wastewater, without affecting the final effluent quality.

Aerobic granulation technology is applied to treat domestic and industrial wastewater. The Aerobic granular sludge (AGS) cultivated has strong properties that appears to be denser and compact in physiological structure compared to the conventional activated sludge. It offers rapid settling for solid:liquid separation in wastewater treatment. Aerobic granules were developed using sequencing batch reactor (SBR) with intermittent aerobic – anaerobic mode with 8 cycles in 24 hr. This study examined the settling velocity performance of cultivated aerobic granular sludge (AGS) and aerobic granular sludge molasses (AGSM). The elemental composition in both AGS and AGSM were determined using X-ray fluorescence (XRF). The results showed that AGSM has higher settling velocity 30.5 m/h compared to AGS.

Abstract A laboratory-scale study has demonstrated the technical feasibility of using a sequencing batch reactor to treat the wastewater from the manufacture of shampoo and other personal care products. The results demonstrate that good treatment (90% removal efficiency for organic substrate as measured by TOD) is possible at an organic loading below 0.70 kg TOD/kgVSS/day. Higher ratios provide some treatment but there may some risk of washing out the biomass when the organic loading exceeds 1.4 kg TOD/kg VSS/day. The effluent produced was suitable for discharge to a municipal sewage system or to a polishing pond but not for direct discharge to receiving waters. The treatment was totally adequate when nutrients were kept in the ratio B0D5/N/P of 100/5/1. Results were obtained for a ratio of 100/2.5/0.5 and the system did not adequately remove organic material. The response to an inadequate supply of nutrients was very rapid and the production of biomass was severely affected. The effect of various ways of filling the reactor were investigated but no significant effect was found. Lower temperatures reduced the efficiency of the system.

The World

All around the world, activated sludge is the classical and traditional biological wastewater treatment for municipal and industrial wastewater. With the development of social and technology, the concentration of pollutants has been increased, so the performance of the old wastewater treatment plants not guaranteed. Therefore, upgrade and reconstruction wastewater treatment system becomes the main task of protection environment, especially in the developing countries. Application biofilms in process biological wastewater treatment is one of technology method and it has many advantages. In the Sequencing Batch Reactor, the Mutag BioChip 25TM provides to the bacteria an optimal habitat at the surface area, increasing rate of Utilization of Substrates 20 – 30% and efficiency of organic matter removal from 10 – 15%.

Abstract The tofu industry is one of the home industries which in the processing process, produces liquid waste. Tofu liquid waste is known to contain very high organic matter such as Nitrogen and TSS so that if it is directly discharged into water bodies, if discharged directly into the environment will cause water. The purpose of this study was to determine and analyse the effect of variations in times and velocity of sequence batch reactor on the optimization of Nitrogen and TSS removal in tofu industrial wastewater by anaerobic bacteria originating from natural sediments. This study uses a Sequencing Batch Reactor, and the waste used is artificial by the characteristics in the preliminary test. In this study, time and speed variations were used in the mixing process. The artificial waste has a TSS value of 2,910 mg/l and Nitrogen of 18.82 mg/l. The results show that using a sequence batch reactor can reduce the TSS value to 66 mg/l and reduce the nitrogen value to 1.214 mg/l.
