Siemens to Provide Kuwaiti Wastewater Treatment Plant with Bioflowsheet+ Solution

Jul 24 2008

Siemens Water Technologies will provide a high-performance nutrient removal systemfor the 180mld (47.5mgd) Kubdwastewater treatment plant (WWTP) located outside of Kuwait City, Kuwait. The solution, which is based on Siemens’ new biological process optimization program– BioFlowsheet+ Solutions, will help the WWTP meet required effluent levels.
Siemens signed the contract for about 5.2million euro ($7.4m) with Kuwaiti contractor Mushrif Trading and Contracting Company of Kuwait City. The plant will be commissioned in 2010.
Siemens`’ proposed BioFlowsheet+ Solution was an alternative to the originally specified conventional MLE (Modified Ludzack Ettinger) process that consisted of an anaerobic selector, anoxic zone and fine-bubble aeration for nitrification, scraper clarification, and sand filtration/disc filtration.
Compared to its conventional counterpart, Siemens` solution will provide superior process design and performance, a smaller footprint, less energy consumption, and compact tertiary filtration.
BioFlowsheet+ Solutions is a new biological process optimization program from Siemens Water Technologies that integrates several key WWTP
operations including biological, solids separation, solids treatment and controls to meet the needs of most wastewater treatment applications. The program evaluates effluent requirements, land
availability and specific cost factors such as energy use, labor, and disposal. The BioFlowsheet+ Solution for the Kubd plantwill consist of four VertiCel systems (in two parallel operating trains), six 46m diameter, high-performance clarifiers and eight Forty-X disc
filters (with 24 discs apiece). The project marks the largest VertiCel systemand Forty-X disc filter orders to date. Siemens will also provide an overall process warranty for the biological process to guarantee the
plant meets required effluent quality levels.
