Booster pump helps RO system keep production steady

A lot of areas use ro system to filter water, Specific energy consumption (SEC) for reverse osmosis (RO) desalination systems has usually been estimated using simplistic analyses that consider an average duty point of operation for a certain plant.
Amore sophisticated and comprehensive approach that accounts for the effects of variable parameters of operation on SEC was recently described, introducing the concept of the “hydraulic envelope”.
Variable parameters include flow rates at variable recoveries, feed temperature and salinity with their resulting pressure requirements, pressure losses caused by membrane fouling, and pressure losses caused by system controls such as feed throttle valves.
Particular attention will be paid to a recently developed, innovative energy recovery configuration that uses a motor-driven booster pump coupled to a Pelton turbine, the so-called ‘PROP’, instead of a single-component high-pressure feed pump. This new energy recovery concept can not only be applied to single-stage RO plants, but also as a highly effective interstage booster for dual-stage Brine Conversion Systems (BCS). The concept has been submitted for patenting. Results of the analysis suggest that the key issue for minimizing SEC is to control the plant over the entire width of the operational range without creating throttling losses. This can only be achieved by using hydraulic equipment that allows for feed pressure adjustment at minimum energy dissipation and eliminates the need for throttling valves. It is shown that the newly developed ‘PROP’ concept provides minimum SEC over the entire range of the hydraulic envelope of a plant, while at the same time allowing for maximum hydraulic dynamic control efficiency of the RO unit. In addition, the ‘PROP’ offers a significant savings potential in terms of capital costs compared to conventional energy recovery strategies.

Several type of pumps for changing human life

Today we will talk about several type of water pump ,which changes our life. 1, Booster pump :The last decades,people who lives in high building can feel pains caused by the low water pressure,especially in rush hour.But now,the convenience booster pump takes to us become a part of our life. We nearly forget it exist.In nowadays,building is taller and taller,but even on the top of the high cloud bulding,the flow of water is also very stable and strong. 2,Ro booster pump:As ro technology developed,ro booster pump step into our daily life,since the pump appeared ,make water clean and safety is not a hard work,this type of pump helps a lot of people drink clean water,avoid disease,especially some people who is required only drink purified water,do not need to pay too much money to buy purified water,we can get it anywhere.Even in desert,bottle water can be brought easily.some sweet water purified by sea water,how magical pump is it? 3, Aquarium water pump ,fishes which we can see on...

Causes of Electric Motor Burning by Water pump

1. First, find out whether the motor burns the bearing (mechanical fault) or the coil (electrical fault). If it is the fault of burning coil, it is mainly caused by overcurrent, sometimes too high or too low voltage will also cause the coil to heat and short circuit, so check that the voltage when running is too different from the rated voltage.There may be several reasons for over-current short-circuiting: A. the equipment is overloaded to make the motor run for a long time at rated or over rated current. In particular, the starting current of the motor is 3-5 times that of the rated current. Therefore, we should try to avoid running with load or full load when starting the equipment (mainly depending on the matching allowance of rated current and normal operating current of motor). B, the motor works in a wet working environment. The insulation of the coils should be checked before the motor starts. The insulation requirements of different voltage grades are also different. May r...

Pump repair--The pump flow is very low

The pump flow is very important,if the flow is too big,the pump can be easily damaged,the motor can be burned. and if the flow is too small,you should also take care,check the pump carefully and find the problems. We can give you some suggestions below ,you can compare your pumps: 1,Check the pump and pump system as the ways of  no water or few water out from pump . 2,Part of pipe and impeller is blocked,there is incrustation inside,valves are not opened completely.first remove the block and incrustation,open valves. 3,If the voltage is very low,choose a pump which can work in low voltage,and keep the voltage stably. 4,impeller is lossy,change a new impeller. Gelaili pump industry is a professional  water pump  supplier,we produce water pump and water pump system,the centrifugal water pump is widely used as shower pump , booster pump, aquarium water pump, coolant pump, dewatering pumps,  dirty water pump ,  ro booster pump . Want to know more ,check our w...
