With the growing spectrum of several industrial, manufacturing, and services concerns at a global level, the consumption of electricity has also been mounted upwards over a period of time. As a matter of cause and effect process, the outcome of high on demand electric consumption in numerous industrial and commercial spheres worldwide has turned out in terms of the shift of most of the industrialists in becoming self sufficient to meet their electricity needs. They are doing so by the adaptation of various alternate power generation techniques and the installation of in-house standby generators at their sites.
PS Bangor City - Case Study
Landustrie supplied two Landy Archimedes screw pumps for doubling the capacity of water storage in the underground storm water bassin at Pumping Station Luke`s Point (Northern Ireland Water).With a capacity of 1,200 l/sec these screw pumps enable the station to deal with heavy rainfall and reduce flooding.Both screws dimension 1950 mm diameter and 6 meter long. Special feature is the use of eco-friendly stainless steel lower bearings which allow for 3-dimensional self-alignment.
Velocity-based analysis of sediment incipient deposition in rigid boundary open channels
Drainage systems must be designed in a way to minimize undesired problems such as decrease in hydraulic capacity of the channel, blockage and transport of pollutants due to deposition of sediment. Channel design considering self-cleansing criteria are used to solve the sedimentation problem. Incipient deposition is one of the non-deposition self-cleansing design criteria that can be used as a conservative method for channel design. Experimental studies have been carried out in five different cross-section channels,...
Water safety planning for small water supply systems: the framework and control measures
A water safety plan (WSP) is a preventive comprehensive risk assessment and management approach to ensuring the safety of a drinking water supply from source to tap for public health protection. The concept was introduced in the last decade in international guidance documents and has been applied widely across a varied range of water supply systems, particularly, the public water utilities and to a lesser extent towards small systems. Mainstreaming water safety intervention for small systems however, would ensure...
Array gain and reduction of self-noise
Abstract—Because an array is composed of many sensors, each making an independent measurement of the wavefield, intelligent combination of the sensor signals should lead to an overall increase in the signal-to-noise ratio. What we are trying to achieve is enhancing the signal with an array beyond what is possible with a single sensor. The array gain measures an array’s signal-to-noise ratio enhancement, and thus also the self-noise improvement of the total array.Index Terms—Array gain, self-noise,...
Potential of phosphatases for express assessment of self-purification at different types of ...
The potential of an express enzymological indicator – phosphatase activity index (PAI) – for assessment of different types of pollution and self-purification potential in running waters was evaluated for three river subcatchments, representative for different ecological situations and impacts. According to the values of correlation coefficients, a significant positive correlation existed among PAI and total microbial count, organic loading and phosphate concentrations. The enzyme activity is useful tool for early...
