The pilot investigation on the use of UV as an alternative disinfectant to NaOCI was started in 1992 at Trani (South Italy) municipal wastewater treatment plant (335 m3/h). The results collected after six months continuous operation enabled us to compare UV and NaOCl disinfection effectiveness on the basis of secondary effluent characteristics, quantify photoreactivation effects, evidence possible DBP formation and assess costs.

Industry Wastewater

Soft drinks industry wastewater from various production lines is discharged into the Industrial Effluent Treatment Plant. The traditional coagulation/flocculation method as first step, followed by biological treatment as second step, has been adopted for treating the soft drinks industry wastewaters. The performance of the plant has been evaluated. It has been found that the effluent characteristics are in most cases in correspondence with the requested standards for discharging the effluent into the Nicosia central sewerage system.

Effluent Characteristics

The objectives of this work were to carry out a complete characterization of textile wastewater, resulting from a textile unit located in the Marrakesh region. A physico-chemical characterization has been performed, focused on organic and toxicological aspects. The cladoceran Daphnia magna was used as the sensor organism and lethal concentration as a criterion to measure the toxicity of textile wastewater. The physico-chemical and toxicological status of a local textile effluent showed considerable values limitation, when compared to the European Union standard limit and Moroccan guide level and other studies. In view of those characteristics, the wastewater effluent from the textile industry should be considered to be treated before discharge to the environment.

Effluent Characteristics

Kandelia candel plants were grown in a simulated tide-tank system in the greenhouse to determine the performance of the mangrove ecosystem in treating synthetic wastewater of various strengths (NW, 5NW and 25NW). NW had a strength similar to the natural municipal wastewater, while 5NW and 25NW had 5 and 25 times, respectively, the amount of nutrients and heavy metals as in NW. The system was flooded daily with artificial seawater to simulate the tidal regime. Synthetic wastewater was irrigated to the system three times a week for 3 months. The results of effluent characteristics showed that the removal efficiencies of nutrients and metals from the wastewater were nearly 98% (except for organic N) and 96%, respectively, in NW and 5NW tanks whereas those of 25NW tanks were 75% for nutrients, 92% for Cd, Cr, Cu and around 88% for Ni and Zn. This study demonstrated that the mangrove ecosystem had a very high capacity to retain or immobilize the nutrients and heavy metals in the wastewater suggesting mangrove wetland had inherent physical, chemical and biological properties for adsorption and utilization of nutrients and heavy metals.

Carbon Filter

The textile dyeing industry is one of the hazardous polluting industries which uses water as the major source for their production and substantially the generation of wastewater leads to be a huge burden in treatment. The existing treatment methods adopted in most of the dyeing industries are said to be very old and its efficiency of removal is very less and at the same time it does not meet the standards for trade effluent discharge as prescribed by the regulatory boards. The study carried out on the application of Activated Carbon Filter (ACF) outlet in three stages of Reverse Osmosis results in reduction of 52% and the Total Dissolved Solids (TDS) is reduced to 226 ppm under the operation time of 10 hours. Significance reduction in pH, BOD, COD, TSS and Sulphates. The results say that the new technology of applying Nano-filtration and ultra-filtration will increase the efficiency of treatment. The effluent characteristics with the help this technology satisfy the standards.
