NASH Vacuum Pumps for Wastewater Treatment Plants
ثبت نشده
چکیده
Many larger wastewater treatment plants use Anaerobic Digestion, a bacterial process that is carried out in the absence of oxygen. Compared to the conventional activated sludge process, Anaerobic Digestion is more energy efficient, reduces dewatered biosolids by 7-12 times (as compared to conventional processes) and produces useful methane gas (biogas). Gardner Denver Nash liquid ring pumps and compressors are used for three applications in this process:

Models for Optimization of Energy Consumption of Pumps in a Wastewater Processing Plant
In this paper, a data-mining approach for modeling pumps in the wastewater preliminary treatment process is discussed. Datamining algorithms are utilized to develop pump performance models based on industrial data collected at a municipal wastewater processing plant. The performance of wastewater pumps is described by two parameters, pump energy consumption and water flow rate after the pumps. ...
متن کاملMapping Thermal Energy Resource Potentials from Wastewater Treatment Plants
Wastewater heat recovery via heat exchangers and heat pumps constitutes an environmentally friendly, approved and economically competitive, but often underestimated technology. By introducing the spatial dimension in feasibility studies, the results of calculations change considerably. This paper presents a methodology to estimate thermal energy resource potentials of wastewater treatment plant...
متن کاملUpgrading Wastewater Treatment Plants Based on Reuse Demand, Technical and Environmental Policies (A Case Study)
Reclamation and reuse programs are an indispensable part of integrated water resource management, particularly in arid and semi arid regions. Yet, the feasibility of sustainable application not only is relied on design, operation and maintenance of wastewater treatment plants, but also could be influenced by the economical and environmental aspects of reuse demands. This study is aimed to illus...
متن کاملModeling and analysis of pumps in a wastewater treatment plant: A data-mining approach
A data-mining approach is proposed to model a pumping system in a wastewater treatment plant. Two parameters, energy consumption and wastewater flow rate after the pumping system, are used to evaluate the performance of 27 scenarios while the pump was operating. Five data-mining algorithms are applied to identify the relationships between the outputs (energy consumption and wastewater flow rate...
متن کاملRapid in vitro tests to determine the toxicity of raw wastewater and treated sewage effluents
Wastewater consists of a complex mixture of substances. During wastewater treatment these harmful substances can be eliminated or degraded. However, persistent compounds released with the treated sewage effluents enter the environment and pose a risk to animal and human life. To determine the potential risks involved, screening tests are needed to monitor wastewater for potential toxic contamin...
