Removal of solid and colloidal dispersions from wastewater

Kurzfassung

A governmental organisation in the Region of Northern Hungary, active in water and wastewater treatment technologies, is seeking innovative technologies to remove solid and colloidal dispersed particles from wastewater. Joint venture, license agreement, technical cooperation, and/or a manufacturing and commercial agreement with technical assistance are preferred forms of cooperation, financial resources are also awaited. The technology should be already on the market.

Details

The requesting Hungarian organisation is planning and supervising programs for treatment of water/drinking water, wastewater, sewage products and effluents, sewage sludge. It provides technical support, expertise and consultancy for all relevant companies and organisations like SMEs, municipalities that plan or operate water works and/or wastewater treatments plants or pollute the environment in the organisation’s territory of competence. The organisation, being in regular contact with municipalities, companies having pollution problems and also with environmental companies that technically solve the pollution problems, can provide among others technical audits, analyses of physical, chemical and biological processes, as well as expertise in designing and construction of water and wastewater treatment plants.
Thus this organisation will act as an interface or coordinator between foreign companies that offer environmental technologies on the one hand, and municipalities, environmental and polluting companies in the Region of Northern Hungary, on the other hand.

The organisation requests novel and efficient technologies to remove solid and colloidal dispersed particles from wastewater of several categories. Preferred technologies involve treatment with mechanical process, micro filtration or membrane techniques.

The technology should be already on the market.

Further requirements related to the technologies offered are as follows: 1. cost-effectiveness; 2. detailed representations of references; 3. possibility for updating to meet the requirements of the more strict future regulations - for at least 10 years after implementation.
