The Project Smart Storm designed a complete, bespoke effluent treatment system to address the 'consent to discharge' parameters, ensuring the new Brewery was discharging within the consent to discharge limits:- Lamellar clarifier to drop out solids and to comply with consent limits (1) pH balancing with acid and caustic for optimal Bio Augmentation (2 & 3) Bio Augmentation in Bio ...
Solids build-up in this open anaerobic lagoon in Tennessee was hampering operations at a large US industrial food waste rendering plant. In just four months, a single application of Bio Dredger biocatalyst broke down solids, with samplings analysis showing 58% Total Solid Reduction (TSR) and 60% Volatile Solid ...
For instance, Fluence added AD to the wastewater treatment system at a major Italian poultry processing plant that was increasing production and had to comply with strict discharge limits. Using AD converted the high COD and nutrient load of the plant’s wastewater into biogas, digestate, and effluent that complies with all discharge regulations. ...
The aerobic tank sludge has insufficient nutrients or an unbalanced ratio of nutrients. The sludge load of the aerobic tank is too high (the effluent is turbid, the COD is high, the sludge is finely crushed after the sedimentation of the aerobic tank and the supernatant is turbid). The sludge load of the aerobic tank is too low, the aeration is ...
Performance data Wastewater: Max. 200 m³/day COD: up to 15,000 mg/l COD load: up to 2,400 kg/day COD outflow: < 1,000 mg/l ...
Performance data Throughput: 50 m³/day COD load: 4,000 kg/day COD concentration: < 80,000 mg/l COD degradation (anaerobic): > 95% Space requirements: 20 x 15 m Control system: PLC, process visualisation Methane reactor: Volume 2 x 200 m³ Material Stainless steel, insulated Biogas yield: > 1,950 ...
Samples were analysed for various physico-chemical parameters (pH, conductivity, O2, BOD5, COD, TOC, NH4-N, NH3, NO3-N, NO2-N, PO4-P, SO4, Cl-, F-, and Fe). Toxicity of the samples was expressed as German regulatory G-values and Toxic units (TU). ...
"The sensor has been really useful and we are developing a good correlation between the COD mass loading and the MET data. Our next step is to use this to further automate our oxygen feed rate to the ...
The system is designed to treat nearly 10,000 kg of organic load per day (kg COD/d), with treatment efficiencies of approximately 95%. ...
The key factor in the choosing AQQA® for this project was the fact that the load of BOD, COD and Ammonia is high but nevertheless the membrane filter must perform without maintenance on site. ...
Municipalities struggle with: Meeting the demand for drinking water and dealing with both, an increased flow and higher COD loading of wastewater. Employing enough technical staff to operate and maintain drinking water treatment installations and WWTP's (wastewater treatment plants) during the peaks. ...
The maximum removals of chemical oxygen demand (COD) obtained during each operation step were 72% (BF 1), 72% (BF 2), and 8% (BF W) for 30 vinasses/70 water; 72% (BF 1), 73% (BF 2), and 66% (BF W) for 40 vinasses/60 water; and 22% (BF 1), 20% (BF 2), and 18% (BF W) for 50 vinasses/50 water. The total organic carbon (TOC) removal was significantly increased using a volumetric ...
Micro-electrolysis and Fenton oxidation were applied to reduce chemical oxygen demand (COD) organic load and to enhance organic components gradability, respectively. ...
Laboratory analysis of the samples before and after EC have shown an effective reduction not only in organic loads in accordance with the COD (chemical oxygen demand) parameter, but also in mineral oil content, toxic metal concentration, and surfactants. The COD in liquid waste from the detergent industry was reduced by 73% and the content of ...
Wastewater was fed continuously to the reactor with step flow increases reducing hydraulic retention time from 55 to 12 hours, increasing organic loading rate from 3 to 33 kg-COD/m3·d. The HyVAB removed on average 91% and 86% of the soluble and total feed COD, respectively, at steady state and loads up to 23 ...
The waste stream contains a high proportion of high strength industrial waste, which results in a typical COD loading of about 2000 mg/L, which is approximately four times the strength of normal municipal waste. ...
Then, electrolysis batch runs were carried out at laboratory scale to test the effect of different process parameters, namely, initial chemical oxygen demand (COD) load (72.9, 33.8, and 0.18 g/L), the addition of Na2SO4 as supporting electrolyte, and adding NaCl along with Na2SO4, on the efficiency of the treatment process. ...
Over the years though, our operations had grown considerably and we received our first complaints from the local wastewater treatment plant about problems with the COD loads in the wastewater. Since I was planning on expanding the business anyway, I started looking for a new technology capable of delivering better quality of the purified wastewater while also ...

The reactor was operated under low dissolved oxygen (DO) concentration (0.3–0.7 mgL−1) and an average applied organic load of 0.5 g COD L−1 d−1 (COD: chemical oxygen demand). Removal efficiencies were higher than 70% for both soluble chemical oxygen demand and ammonium, with average effluent concentration of 51 ± 15 mg COD L−1 ...
