Water pressure too low: Possible causes and remedy
In the physical sense, water pressure is the hydrostatic pressure in water. It increases with increasing water depth and is referred to as the water column and measured in meters of water column, mH2O or mWS for short. A meter of water column is about 0.10 bar. In everyday life, water pressure refers to the the force applied per unit area with which the fresh water - alternatively also called tap ...

Optimal solving of the pump scheduling problem by using a Harmony Search optimization algorithm
Pumps are installed in water distribution networks (WDNs) to ensure adequate service levels in the case of poor water pressure (e.g. because of low elevation of reservoirs or high head losses within the WDN). In such cases optimal pump scheduling is often required for the opportunity of significant energy saving. Optimizing the pump operation also allows a reduction in damage and maintenance ...

Dust Suppression System--Fog Cannon
Fog cannon machine, also known as mist cannon dust suppression machine and water mist cannon spraying machine, is a device specially developed for dust suppression. Now the equipment can be used to print dust in the environment or in places with large dust such as mines, docks, and stone quarries. The sprayed water mist can well condense with the dust, and the dust falls under the action of ...

What are IP Ratings and why do they matter?
IP Ratings (formally called Ingress Protection Rating) are an international standard that determines the level of sealing an electrical enclosure has. The environment your electrical enclosure will be in determines which IP rating you need. The harsher the conditions the higher rating you need. The rating has two numbers. Great. So what do they mean? The first number is the protection level from ...

The study on increase low permeability reservoir adsorption ability with nano–polymerisation emulsion
Low permeability reservoirs always have some problems such as long–termed high injection pressure, low injection rate, the great variation of injection pressure during the water injection because of the compact and complicated structure. So it is necessary to reduce injection pressure and augment injection rate. Water–based nanometre polysilicon break through the limitation of organic scattered ...

Gas Lift Optimisation (GLOP) Efforts Supplemented by CO₂ Tracer Application
We were excited to see that our customers, Petronas Carigali, have recently had their work on Gas Lift Optimisation (GLOP) published in One Petro.Gas Lift Optimisation Abstract Field B, located offshore in Malaysia relies on gas lift optimisation due to the high water cut behaviour of the reservoir paired with low-medium reservoir pressure. Traditional techniques to measure the enhancement put a ...

Fifteen years of experience with standardized reference radiometers for controlling low-pressure UV disinfection plants for drinking water
The only practicable way to control the disinfection capability of a UV disinfection plant for drinking water all the time is to use a UV radiometer. According to the Austrian Standard M5873, this plant radiometer is a standardized part of each plant. The standard defines a so-called reference radiometer (RRM) as well. This is necessary because a plant radiometer has to be controlled ...

Experimental observation on factors affecting intrusion volumes during low or negative pressure events
External water intrusion during low or negative pressure transient events in urban water supply systems may cause pollution and health problems. The volume of intrusion pollutants is one of the significant indicators that can reflect the degree of health risks when a pollution incident occurs. A pilot-scale platform was constructed in this study to simulate intrusion events, which were caused ...

Evaporation sensor introduction
Summary: Before the emergence of evaporation sensor, the calculation methods of water surface evaporation can be roughly divided into two categories.One is theoretical calculation method, the other is empirical calculation method.The so-called theoretical calculation methods are those with strong physical basis, such as heat balance method, aerodynamic method and water balance method.These ...

Remediation of simazine from water through low-pressure thin film composite membrane using surfactants
The investigation was carried out to remediate simazine from water by the pressure driven filtration techniques (viz. nanofiltration, reverse osmosis). The separation of simazine through the membranes showed similar trend as glucose (organic marker) and salt. Surfactant-mediated filtration showed better performance of the membranes, though it depends on the nature of membranes and surfactants. ...

The potential for health risks from intrusion of contaminants into the distribution system from pressure transients
The potential for public health risks associated with intrusion of contaminants into water supply distribution systems resulting from transient low or negative pressures is assessed. It is shown that transient pressure events occur in distribution systems; that during these negative pressure events pipeline leaks provide a potential portal for entry of groundwater into treated drinking water; and ...

Method to determine the power efficiency of UV disinfection plants and its application to low pressure plants for drinking water
In this paper we present a method to determine the power efficiency of ultraviolet (UV) disinfection plants and apply this to low pressure plants for drinking water. In UV disinfection plants the water flow is regulated to ensure that microorganisms receive the necessary fluence for inactivation while passing through. The flow depends on the UV transmission (UVT) of the water. The lower the ...

Benefits of high energy UV185 nm light to inactivate bacteria
Inactivating and eliminating bacteria from ultra pure water (UPW) systems is always a significant problem for semiconductor and pharmaceutical industries. To alleviate the problem, ultraviolet (UV) radiation—both monochromatic UV254 light and high pressure UV185 light—is traditionally used for bacterial sterilization and in the case of the later, breakdown of trace organic molecules. The focus of ...
