LAR delivers measuring technique for the worldwide first semicentralized Supply and Treatment Center (STC) in Qingdao, P.R. China
On the occasion of the „World Horticulture Exposition 2014” (WHE) in Qingdao, China, the Supply and Treatment Center (STC) Qingdao of the project SEMIZENTRAL, was opened April 27, 2014. It is the worldwide first reference plant following the semicentralized, integrated infrastructure approach. The center will serve approximately 12,000 people.
SEMIZENTRAL is an infrastructure approach for future cities. It is an alternative for extensive, centralized systems with long lead times and insufficient scalability. The innovative approach towards semicentralized supply and treatment systems has been developed to serve new-build residential areas in fast-growing metropolitan environments. Each urban district is provided with a flexible integrative infrastructure system for water, wastewater, and waste, adaptable to the respective need.
The SEMIZENTRAL approach combines the traditionally separated sectors of water, wastewater, waste, and energy. Before being treated in the supply and treatment center, wastewater streams (so-called grey water and black water) are collected separately. Sewage sludge is co-treated with organic waste to produce biogas which in turn is used for energy generation.
During the approximately three years of planning and operational attendance of the semicentralized STC Qingdao, 14 partners from Germany, the Tongji University Shanghai and the Qingdao Technological University worked together in a cooperative consortium. The TU Darmstadt maintains a partnership of more than 30 years with its Chinese partners.
The following supporters and sponsors have made important material contributions towards the realization of the SEMIZENTRAL approach. Our sincere thanks go to:
