Combined biological and physico-chemical treatment of filtered pig manure wastewater has been investigated on the pilot installation operated under ambient temperatures (15-20°C) and included: i) UASB-reactor for elimination of major part of COD from the filtrate; (ii) stripper of CO2 + fluidised bed crystallisator for phosphate (and partially ammonia) removal from the anaerobic effluents in the form of insoluble minerals - struvite (MgNH4PO4) and hydroxyapatite (Ca5(PO4)3OH); (iii) aerobic-anoxic biofilter for polishing the final effluent (elimination of remaining BOD and nutrients). Under overall hydraulic retention time (HRT) for the system of 7.8 days, the total COD, inorganic nitrogen and total phosphorous removals were 88, 65 and 74%, respectively. A decrease of the overall HRT to 4.25 days led to 91, 37 and 82% removals for total COD, inorganic nitrogen and total phosphorus removals, respectively. The approaches for further improvement of effluent quality are discussed.

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.

Recent Developments

Abstract Recent developments in the application of activated carbon to wastewater treatment are reviewed. Particular emphasis is placed on the physico-chemical treatment of municipal waste. Technological development, adsorptive behaviour, and research needs serve as the three primary discussion topics.
