Siemens Water Technologies announces BioFlowsheet+ Solutions, its new biological process optimization program, which integrates the main unit operations of a wastewater treatment plant, by evaluating effluent requirements, land availability and specific cost factors such as energy use, labor, and disposal costs. Through Siemens' extensive process knowledge and product expertise, its biological treatment experts can review an entire system and ensure process integration and optimization--with a single point of process responsibility.

"Siemens is in a unique position to combine years of process knowledge, along with the broadest array of biological technologies," said Chuck Gordon, Executive Vice President of Siemens Water Technologies. "This provides real value to our customers, which is proven by the explosion of interest in this type of solution application."

The BioFlowsheet+ Solutions experts offer municipalities and engineering firms a single point of contact from process design through start-up and long-term support. By harnessing its biological treatment expertise, Siemens is able to create a stronger collaboration with customers to provide a complete process-based solution to meet the specific needs of communities and industry.

BioFlowsheet+ Solutions optimizes the integration of several key wastewater plant operations including biological, solids separation, solids treatment and controls. This biological product and process knowledge and more focused coordination provides some key advantages such as integrated controls, design support, scope selection, system responsibility, and project execution/coordination.

Siemens WT offers solid and differentiating technologies to meet the needs of every application of wastewater treatment. The wide range of proprietary technologies include biological technologies such as Orbal, VLR, sequencing batch reactors and Verticel processes; solids separation technologies such as Rim Flo/ Tow Bro clarifiers and Memcor membranes; and solids treatment such as the Cannibal process and anaerobic/aerobic digestion.

An example of a BioFlowsheets+ solution is an 8.0 MGD wastewater treatment plant in Peru, Indiana. After reviewing the city's expectations and requirements, the Siemens experts recommended a Vertical Loop Reactor (VLR) process using existing tankage with a high performance RimFlo TowBro clarifier design for high peak flows along with the Cannibal biosolids reduction system for low sludge production. The results were an economical construction cost, a considerable reduction in sludge production from 1.32 MG/year to 130,000 gallons/year; significant power reduction; improved performance with ammonia < 0.5 mg/l, nitrate 1-2 mg/l; and better management of storm flows.
