Fenton’s reagent has been effective in treating various industrial wastewater and wide variety of dyes. Fenton process gives colour removal efficiency is 98% at pH 3 at FeSO4 of 0.2 gm/lit. and
Biological treatment of model dyes and textile wastewaters
A local textile company in San Cibrao das Viñas (Ourense, Spain) kindly provided the real effluents (a liquid wastewater and a semi-liquid sludge). Table 1 . Chemical structure, wavelength (range and maximum absorbance) and type of dyes used in this work.
575 from Spain) and compared its performance with ferric chloride and polyaluminium chloride for treatment of textile wastewater at the lab and scales. The results found that natural coagulant was more effective as 36% lower dose of natural coagulant was enough to achieve the same level of treatment as inorganic coagulant and less toxic in both

treatment of industrial wastewater to achieve maximum removal of COD, BOD and color.2 Therefore, Amudaa & Amoob3 investigated the effect of coagulant dose, polyelectrolyte dose, pH of solution and addition of polyelectrolyte as coagulant aid and found to be important parameters for effective treatment of textile industrial wastewater.
In this study, three different biological methods—a conventional activated sludge (CAS) system, membrane bioreactor (MBR), and moving bed biofilm reactor (MBBR)—were investigated to treat textile wastewater from a local industry. The results showed that technically, MBR was the most efficient technology, of which the chemical oxygen demand (COD), total suspended solids (TSS), and

In this sense, advanced oxidation processes are possibly one of the most effective methods for the treatment of wastewater containing organic products (effluents from chemical and agrochemical industries, the textile industry, paints, dyes, etc.).
TREATMENT OF TEXTILE WASTEWATER BY ADVANCED OXIDATION
The use of conventional textile wastewater treatment processes becomes drastically challenged to environmental engineers with increasing more and more restrictive effluent quality by water authorities. Conventional treatment such as biological treatment discharges will no longer be tolerated as 53% of 87 colours are identified as non-biodegradable. Advanced oxidation processes hold great
The study explores pretreatment of textile Wastewater by using CaO2/H+/Fe2+ advanced Fenton-like oxidation technology. The result show that when the initial COD is 2200mg/L, the pH=3, the reaction time is 40min, the speed is 150r/min, the dosage of calcium peroxide is 24g/L and the dosage of FeSO4 is 2g/L at 25°C, the removal rate of COD reach 81.82% and the decolorization rate is 99.93%.
- Which urban organic waste treatments are being implemented in Thailand?
- This section provides examples of urban organic waste treatments that are being implemented in Thailand. From the characteristics of MSW in Thailand, composting tends to be the most appropriate technology for waste disposal and treatment. A high percentage of organics makes waste suitable for composting (Table 3.2 and 3.3).
- Does Thailand have organic waste?
- Thailand's municipal solid waste contains a major component of organic nature. It can be seen from Tables 3.1 and 3.2 that most of the waste shares the same characteristics, which include high organic content and recyclable waste.
- What are the goals of solid waste management policy in Thailand?
- Targets of the policy on solid waste management are summarized as follows: Establishing a center for municipal hazardous waste management in each region. To achieve these targets, integrated waste management is included in the national agenda. Solid waste management in Thailand has moved toward national environmental policies and plans.
- Why is integrated waste management important in Thailand?
- To achieve these targets, integrated waste management is included in the national agenda. Solid waste management in Thailand has moved toward national environmental policies and plans. The policy is developed mainly for integrated solid waste and wastewater management (UNEP, 2012).
