Quite often jetties are fitted with their own water pumps, taking suction into the sea or river. The jetty fire water grid is often connected to the main plant fire water system as a backup. Care should be taken to avoid seawater corrosion of the main site fire water system. 

The major elements of a water supply system are the raw water source (lake, river, reservoir, or groundwater aquifer), the water treatment plant, the pumping stations, and the distribution system consisting of pipes and intermediate storage reservoirs. 

In order to prevent polluted river water from reaching your drinking-water system, you want to know how much time you have to turn off the pumps once a pollution cloud in the river has reached the location adjacent to the well. In your considerations you assume that the concentration of the pollutant suddenly increases from 0 to a value 10 times above the maximum tolerable drinking-water concentration and then remains at this level. (1) Take the worst-case scenario and calculate how much time you have to turn off the pumps. (2) How much does this time change if you assume that the concentration in die river reaches 1000 times the maximum tolerable drinking-water concentration ... 

A very large petrochemical facility has many cooling systems and a variable water quality due to seasonal fluctuations. The river water makeup supply water is pumped approximately 100 km across a desert plain. The supply water pH can quickly increase to 8.6, the TDS rises to 1300 ppm, SS to 500 ppm (before clarification), chlorides to 650 ppm, and total hardness to 600 ppm. As a consequence, priority is given to stabilizing the makeup water quality as much as possible using acid dosing, but control is poor and acid incursions take place. 

A through-flow system with a continuous feed from two pump systems (illustrated in Figure 4.3.2) was used in order to minimize the rate of depletion of PAHs due to adsorption to the walls of the system, and to uptake by passive samplers deployed in the tank. The first pump provided a circulation of the Maas river water at a constant 10 Lh-1 flow rate, and the second one added a solution of 16 PAHs (prepared by the dilution of a stock working solution containing equal concentrations of the test 16 PAHs) in acetonitrile at a rate of 0.1 mF min-1. 

Phenylurea herbicides are widely used for weed control around the world. This method works directly on a filtered river water sample. This fully automated method was accomplished on the PROSPEKT automated system and was interfaced directly to an HPLC. Figure 10.18 shows the configuration of the system. It consists of the solvent delivery unit (SDU), which prepares the sorbent, pumps the sample, and elutes the cartridge. The system also includes Marathon autosampler, which coordinates the 10-mL water samples, and the...

Some of the first reactors that were constructed used a single-pass cooling system. The eight reactors constructed for plutonium production at Hanford, USA, between 1943 and 1956, pumped water from Columbia River through the reactor cores then delayed it in cooling ponds before returning it to the river. The river water and its contents of particles and components were thereby exposed to a great neutron... 

The normal source of makeup water to the K-, L-, and P-Reactor Disassembly Badns is from the filtered water system throu two makeup water fines. One of the fines supplies the MB, while the other supplies the VTS badn (Ref 8-28). Inhered water to eadi badn is supplied through a manual blodc valve and then to a pneumatically operated butterfty valve. The water then flows into the respective section of the Disassembly Bam Filter water can be automatically controlled, but is not usually operated in this manner. Makeiq> water addition is normally manually controlled via the manual block valves. The emergency cooling water pump suction header CW-39 and the river water header RW-1 were once alternative sources of mak water to these Disassmbly Basins. Each of these alternate sources of water have been drained and isolated from the Disassembly Basins (Ref 8-27), and are not considered as sources. 

Existing Water Controls. In some waterways, controlling the flow of water can confine heavier-than-water spills. Tidal streams can simply be diked. Waterways used for irrigation may have a system of diversion gates that can be closed or a pumping system that can be shut down. Typically, streams, creeks, and rivers are not controlled and require a different approach. 

Because of the potential Importance of the moderator cooling system a high degree of reliability has been provided Circulation pumps are powered both vlth BPA and local electric power In the event of failure of both power systems, cooling will be supplied by raw river water on a once through basis ... 

The HGP, owned by the Supply System, received steam via the steam piping system from the N Reactor. The HGP consists of two 430-MW (electrical) low-pressure turbine generator systems with associated auxiliary equipment normally found in a steam power station. The HGP is operated by the Supply System. The HGP condensers and auxiliary cooling systems were supplied by raw water pumped from the Columbia River and discharged back to the river approximately 90 m (300 ft) upstream from the N Reactor raw water intake structure.

Reactor generated heat is transferred to the circulating raw water system in the dump condensers for ultimate dissipation in the Columbia River. About 400,000 gpm of untreated Columbia River water will be pumped from the river, through the tube side of the diimp condensers and turbine condensers, and back to the river. Flow control is exercised primarily through the number of circulating raw water pumps online however, trimming adjustments are possible at each of the condensers. Since the drives for these pumps do not Incorporate speed control, fluctuations in river level will also effect the flow rates in this loop. 

The application supported the domestic water delivery system for half of the Parkview Towers, a 684-unit affordable housing complex in West New York, NJ. BuUt in 1974, and located blocks from the Hudson River, the pumping station delivers domestic water to one of the twin 24-story apartment building towers.
