The catalytic thermolysis (CT) process is an effective and novel approach to treat rice grain-based biodigester effluent (BDE) of the distillery plant. CT treatment of rice grain-based distillery wastewater was carried out in a 0.5 dm(3) thermolytic batch reactor using different catalysts such as CuO, copper sulphate and ferrous sulphate. With the CuO catalyst, a temperature of 95°C, catalyst loading of 4 g/dm(3) and pH 5 were found to be optimal, obtaining a maximum chemical oxygen demand (COD) and colour removal of 80.4% and 72%, respectively. The initial pH (pHi) was an important parameter to remove COD and colour from BDE. At higher pHi (pH 9.5), less COD and colour reduction were observed. The settling characteristics of CT-treated sludge were also analysed at different temperatures. It was noted that the treated slurry at a temperature of 80°C gave best settling characteristics. Characteristics of residues are also analysed at different pH.

“…The current challenge is the financially realistic implementation of new and highly effective but cost and energy intensive, treatment technologies. Advanced wastewater treatment goes beyond the level of conventional secondary treatment to remove significant amounts of nitrogen, phosphorus, heavy metals, biodegradable organics, bacteria and viruses [7]. Electrocoagulation is a technique used for wastewater treatment, industrial processed water [8] and medical treatment [9].…”

Electrocoagulation (EC) treatment can be used as an effective alternative to the existing treatment methods. It is a distinct, economical and an environmental friendly choice for meeting water treatment discharge standards and compliance requirements. Due to improved material of construction and process design, the EC process is widely accepted. Presently, this process has gained attention due to its ability to treat large volume of effluent with low cost. The EC process includes the in-situ generation of coagulants via the electro-dissolution of a sacrificial anode, which is usually made up of iron or aluminum. This paper presents a review of the research works available in the open literature on the electrochemical treatment of industrial effluent such as textile, pulp and paper, paint, food, electroplating, distillery, etc. The mechanism and design consideration for electrochemical treatment of wastewater is also presented.

“…In addition to this, coagulation is very often a part of the treatment process for industrial effluents. Coagulation has been studied broadly in the treatment of effluents for example from the pulp and paper industry [3], textile industry [4], tanneries [5], distilleries [6], petrochemical industry [7] and palm oil mill industry [8]. In industrial effluent treatment, coagulation is often used to remove such impurities that either cannot be removed with biological treatment or are harmful to its operation.…”

The coagulation efficiency of novel coagulant aluminium formate was studied in the treatment of highly contaminated effluent from a styrene butadiene latex manufacturing plant. The coagulation behaviour of the aluminium formate was compared to the behaviour of the commonly used polyaluminium chloride and aluminium sulphate. The effects of the coagulant type and dose and coagulation pH on the treatment efficiency were studied as well as the role of polyacrylamide coagulant aid. Floc separation was done using three different methods: sedimentation, filtration and centrifugation. Their functionality was evaluated as part of the coagulation performance studies.Good purification results were obtained with all of the tested coagulants, the lowest residual turbidities achieved being 0.7 NTU with aluminium formate, 1.4 NTU with polyaluminium chloride and 0.7 NTU with aluminium sulphate. It was also observed that aluminium formate is as effective as commercial coagulants and is thus a potential novel coagulant chemical due to its less harmful and biodegradable counter anion. When using only aluminium coagulants, flocs were found to be too fine to be removed by sedimentation but they could be effectively removed by filtration or centrifugation.The use of polyacrylamide was found to be useful in the sense that it enables the separation of flocs by simple sedimentation because the floc size is significantly increased. In this study new knowledge about the coagulation behaviour of of highly contaminated effluent from latex manufacturing was gained and aluminium formate was proved to be promising coagulant also in industrial effluent treatment.
