This paper depicts the research conducted at a micro-pilot scale on autochthonous cultures in order to develop adequate technological solutions for the treatment of wastewater resulting from shrimp cultures (Palaemonidae) that would ensure the protection of the Black Sea ecosystem and constitute an applicable tool for the development of aquaculture in Romania. The proposed objectives were attained by adopting an integrated system of marine cultures shrimps-mussels-macrophyte algae, followed by a conventional chemical treatment step using aluminium sulphate recovered from metallurgical slags. This system together with wastewater treatment ensures an optimum development of species and a minimum load of pollutants in the aquatic environment.

Treatment Facilities

Most of the wastewater treatment facilities in the upstream areas of dams in Korea are small and scattered and the local governments of these areas are financially very poor as well. Owing to these characteristics, though they directly impact the quality of water resources, operations and management of these facilities have been non effective. So, in this research, Korea Water Resources Corporation (K-water) has tried to integrate operations and management (O&M) of wastewater treatment facilities in these areas to maximize operating efficiency. Although there have been some difficulties measuring effects of an integrated system, we could see many positive consequences including operating cost reduction, effluent quality and process efficiency elevation, and customer service improvement in the centralized O&M.

Textile Dyeing Wastewater

Two systems using ash–cinder and dust–offgas to treat textile dyeing wastewater were studied, one being an ash-cinder filtration adsorption system, and the other an integrated system consisting of ash–cinder filtration–adsorption and dust/offgas scrubbing adsorption, in which high-color dyeing wastes were introduced to the scale-removal system of a boiler, resulting in both hydraulic antiscaling and wastewater treatment. Because of the very low cost of wastewater treatment and the saving of antiscaling process, comprehensive treatment and utilization of various wastes was sucessfully realized.

The TELEMAC project brings new methodologies from the Information and Science Technologies field to the world of water treatment. TELEMAC offers an advanced remote management system which adapts to most of the anaerobic wastewater treatment plants that do not benefit from a local expert in wastewater treatment. The TELEMAC system takes advantage of new sensors to better monitor the process dynamics and to run automatic controllers that stabilise the treatment plant, meet the depollution requirements and provide a biogas quality suitable for cogeneration. If the automatic system detects a failure which cannot be solved automatically or locally by a technician, then an expert from the TELEMAC Control Centre is contacted via the internet and manages the problem.
