BBA emergency pump units for a nuclear power plant

by BBA Pumps  (Feb. 26, 2015)

Following the Fukushima nuclear disaster in 2011, safety regulations at many nuclear plants have been considerably tightened, this has led to an increased demand for fire fighting pump systems. These systems must comply with extremely strict requirements and regulations. Working closely together with the Belgian distributor Rental Pumps, BBA Pumps ...

Seawater Biotoxicity monitoring to protect the coastal waters of Italy

by microLAN On-line Biomonitoring Systems  (Jan. 1, 2015)

The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares ...

Pumps for the Booming FPSO Sector

by Sulzer Ltd  (Mar. 11, 2015)

In the last few years, several new offshore oil fields have been discovered. The current findings from Petrobras and other companies in the pre-salt province, located in the Brazilian continental shelf, suggest reserves of over 50 billion barrels of oil. Extracting the pre-salt oil is challenging and done increasingly with floating production ...

Southside, Arkansas - Case Study

by Environment One Corporation  (Mar. 9, 2015)

Rural area faced failing septic tanks in soggy land that didn't perc well. The Problem Failing septic tanks needed to be replaced. Gravity sewers were cost-prohibitive, requiring deep trenches and massive disruption. The Solution E/One's grinder pump stations easily replaced septic tanks.

Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River

by Inderscience Publishers  (Mar. 2, 2015)

The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the ...

Optimal operation efficiency and control of water pumps in multiple water reservoir system: case study in Korea

by IWA Publishing  (Feb. 4, 2015)

Pumping regimes for water distribution systems have been established to reduce pump operation costs. Optimization of water reservoir networks has been studied extensively for operating pumps efficiently. According to research, optimization reduces pump operation costs by approximately 10–20%. However, comparing economic benefits ...

Optimization of pumping schedule based on water demand forecasting using a combined model of autoregressive integrated moving average and exponential smoothing

by IWA Publishing  (Feb. 4, 2015)

Stable water supply to end users is the most important element in water supply systems (WSSs). The portion of energy used by the water distribution system is up to 40% of the total energy consumed by WSSs. To save energy cost for pumping systems, a number of attempts have been made. Especially, an optimization scheme for scheduling the ...
