New System Improves Coking Wastewater Treatment Efficiency
According to the IPE researchers, the installed systems now can treat more than 55.2 million tonnes of coking wastewater every year. Over the past three years, the systems have treated 152 million tonnes of coking wastewater, recycling 750,000 tonnes of tar and reducing emissions of 240,000 tonnes of chemical oxygen demand as well as 90,000 tonnes of ammonia nitrogen.

An integrated three-dimensional electrochemical system
In our previous work, 3DERs were combined with 3DBERs to treat coking wastewater ( Wu et al., 2025 ). Results demonstrated that at a hydraulic retention time (HRT) for the 3DERs of 5 h, 79.6% of COD and 76.3% of total nitrogen (TN) are removed at an energy consumption of 15.60 kWh m −3.
The integration of magnetically immobilized cells of JB and an E-Fenton process into one entity has been designed to prepare a novel integration system to improve the treatment efficiency of phenol, pyridine, and quinoline in coking wastewater. The optimal pH for the integration system was 3.5. Degradation rates of phenol, pyridine, quinoline, and COD by the integration system were significantly exceeded the sum degradation rates of the single E-Fenton process and magnetically immobilized
Coking wastewater treatment for industrial reuse purpose
Zhao has already demonstrated that employing MBR following A 1 /A 2 /O process was more efficient and reliable in pollutants and acute toxicity reduction than the conventional A 1 /A 2 /O system in coking wastewater treatment, and this advantage was owed to the creation of a low food to microorganism environment to strengthen refractory substances degradation and reduce sludge pro- duction rates (Zhao et al., 2009a, 2009b).

New Technology Improves Adelaide’s Wastewater Treatment
A spokesperson from SA Water explained that a key challenge for the project from inception was the ability to transition from the old control system to the new. “Apart from the complexity behind the wastewater treatment process, transitioning from the old to the new system posed a high risk in terms of plant performance and operability.
The Connected Enterprise Improves Water Plants. You need to be able to extract data from within your industrial or municipal water treatment assets. The convergence of IT and OT is also on the lips of just about everyone in industry. Do you have a vision for how you can embrace data and new technologies to improve your operations?
Treatment of high strength coking wastewater
In this study, a laboratory-scale membrane distillation (MD) system was developed for advanced treatment of biologically treated coking wastewater (BTCW), while the effect of pre-coagulation was
“Wastewater treatment facilities of all sizes can realize significant energy reduction and cost savings by effectively controlling dissolved oxygen in aeration basins. Informed selection of equipment supplier, measurement technology, mounting technique and maintenance strategy will maximize ROI.”
- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
- Can polyacrylamide be used for drilling?
- However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).
- What is polyacrylamide used for?
- Hence, it is an earth-stabilising fluid that is designed for a variety of applications in the geo-construction industry such as tieback anchors, diaphragm walls, horizontal drilling, tunnelling, slurry trenching, drilled shafts/bored piles, and others. 6.1. Polyacrylamide in drilling technology
- Which polymers are used as drilling fluid treatment agents?
- Natural polymers such as starch, xanthan gum, and other biopolymers are widely used as drilling fluid treatment agents, (15−18) but their use is limited because of problems such as salt and temperature resistance.
