Electrocoagulation Technique for the Treatment of Effluents from Metal Working Fluid | Chapter 1 | Chemical and Materials Sciences: Research Findings Vol. 3

Using mild steel, electrocoagulation is a successful method for treating Metal Working Fluid (MWF) industrial effluent. The goal of the current study is to determine how electrolysis time, applied charge density, and electrolyte pH affect the effectiveness of electrocoagulation in treating MWF effluent. According to the current experimental findings, electrocoagulation is an excellent method for treating wastewater.  The electrolysis time of 55-60 minutes, for a current density of 3 A/dm3 and pH 7 at a temperature of 350C effective treatment of the effluent was observed. It was found that the highest COD and color removals were 95% and 98%, respectively. Several adsorption isotherms were used to describe the electrocoagulation process, and it was shown that the predictions of the Langmuir isotherm models agree well with the experimental findings. Langmuir isotherm models (R²>0.99) provided a better fit than Freundlich models for the electrocoagulation process.

Valorizing Plastic Wastes and Textile Sludge as Composites | Chapter 13 | Recent Progress in Science and Technology Vol. 9

 The fabric industry is a major beginning of water pollution in the Tiruppur domain of Tamil Nadu, India. The strict implementation of discharge treatment plants in big textile industries, in addition to common effluent situation plants for small scale activities, has helped to mitigate the question. However, the sludge caused as a result of the treatment of fabric industry discharge poses storage and disposal issues on account of high concentrations of heavy metals, sulphates, and chlorides. When mud is kept in open yards and dropped in landfills, these chemicals and heavy metals another time constitute a important threat to the environment. Once more, these entities erode into surface and rainwater. So skilled is a cycle of troubles caused by both fabric industry discharge and treatment plant sludge of fabric industry. Thus, there are various studies being conducted on a all-encompassing scale to incorporate the sludge into construction materials. Waste flexible may be the apt cover for Textile sludge.  The attempts to involve sludge as an inert essence into concrete using various types of binders, including cement, geopolymer, and flexible, are discussed in this work. Plastic production often decay into micro plastics that can corrupt ecosystems and harm bio-history.  This study demonstrates a shy advance in attempts to encapsulate textile mud using gone oil and waste polypropylene and polyethylene plastic in differing ratios for valorizing.

Determination of the Seasonal Variation of Physicochemical Characteristics of Brewery Industry Effluent and Receiving Water of Ikpoba-Oha Rivers, Benin City, Nigeria | Chapter 01 | Emerging Challenges in Environment and Earth Science Vol. 2

 The current research focuses on determining the physicochemical properties of brewery effluent and receiving water, which serves as a source of drinking water, fishing, and agricultural irrigation for the community. During the wet and dry seasons of 2016, the impact of brewery effluents on the water quality of the Ikpoba-Oha River was investigated. pH, temperature, total solids, total dissolved solids, hardness, BOD, COD, DO, chlorides, phosphates, and sulphates were all measured in water samples taken from three different locations along the river. Samples were taken at three different locations: point 1 (effluent), point 2 (upstream), and point 3 (downstream) (downstream). The pH (5.90-8.38), temperature (25.20oC-33.15oC), chlorides (12.0-129.2 mg/l), phosphates (0.9-20.48 mg/l), sulphates (3.30-53.0 mg/l), nitrates (3.8-17.20 mg/l), DO (2.3-4.15mg/l), Total Hardness (12.10-425.6 mg/l), Ca hardness (6.0-296.4 mg/l), Because of the water dilution effect, the levels of most of the parameters evaluated are normally greater near the point of effluent released into water bodies and distributed to less harmful circumstances downstream.

Improving Fish Production in a Locally-Designed Aquaculture System | Chapter 5 | Novel Perspectives of Engineering Research Vol. 4

 This paper describes a lab-scale recirculating aquaculture system (RAS) that reduces, recycles, and reuses wastewater from fish farms. A biological treatment unit, a settling tank, and a fish tank are all included in the system. For 21 days, four fish samples were housed in the tank. Then, for 16 days, highly concentrated fish farm wastewater was continuously recirculated to build up a significant mass of bacteria on the filter. The rationale for this is to guarantee that proper nitrification processes were in place before the fish were placed in the fish tank to be reared. The ammonia, nitrite, nitrate, dissolved oxygen, pH, and total suspended particles levels in RAS were all within permissible limits for African catfish culture, according to the results of water analysis. The RAS for the 21-day culture consumed 32.89L of water and resulted in a weight gain percentage ranging from 17.69% to 37.05%. This demonstrated that the system is capable of maintaining the required effluent quality for catfish production.

Study on Phytoremediation Potential of Vetiver Plants and Its Amelioration by Ascorbic Acid in Constructed Wetlands | Chapter 6 | Challenging Issues on Environment and Earth Science Vol. 8

 The primary goal of this research is to evaluate the performance of vetiver plants (Vetiveria zizanioides L. Nash) in phytoremediation of service station wastewater in artificial wetlands under controlled greenhouse conditions. The study also attempts to see how vetiver plants respond to ascorbic acid (AA) amendment after being treated with service station effluent. The study's findings revealed that seven days of ascorbic acid (10 mg/mL) treatment on alternate days for up to 15 days to the service When compared to un-amended wastewater treated vetiver plants, station wastewater treated vetiver plants improved their growth, tolerance, and hyper-accumulation capacity. According to the findings, adding calculated amounts of ascorbic acid to metal-contaminated soil/wastewater improves vetiver plants' phytoremediation potential by raising their tolerance to heavy metal stress.
