Water pumping

Background: Lehigh University has developed a forward osmosis separation processes using magnesium oxide and carbon dioxide. The invention can purify water through a Forward Osmosis process from both surface water and saline water. The invention can concentrate waste from a dilute waste stream. Technology Description: In various applications it may be desirable to concentrate species of interest which are present in solution.

A collective water pumping system for domestic use and/or irrigation purposes in areas with no grid power or erratic supply of power from grid. An array of solar panels connected in series and parallel configuration generates the power and voltage required for the ATV312 Solar unit to drive the motor. The DC to AC frequency converter in the solar drive converts the DC voltage input to the drive to variable 3-phase AC voltage and frequency.

Northwestern researchers have developed the ability to store large-scale electrical energy for renewable energy sources such as wind and solar. Established energy storage technologies such as hydroelectric water pumping and underground compressed air storage are limited to specific geographic sites and most batteries and ultracapacitors have limited energy storage capacities and times.

The Easy Photovoltech Solar Water Pump is specially designed to lift water for irrigation, horticulture farms, gardens, drinking and other similar applications. Solar powered water pumps are good alternatives for areas where there is no electricity or scarcity of power supply. Easy Photovoltech's solar water pump systems can be easily installed and requires minimum maintenance.

Solar pump controller is specially designed electronics to run the solar pump through solar power.

It will get maximum possible power from solar panel for particular point of time by using maximum power point tracking (MPPT) Algorithm. It also controls all the parameters to run the pump in safe environment and provide many useful protections like, dry run, over voltage, under voltage, reverse polarity etc.

The MAGNA3 pumps make up a broad range of small, medium and large circulator pumps fitted with communication equipment and motors with electronic speed control based on permanent magnet (PM) and compact stator motor technology.

The MAGNA3 is an innovative member of the Grundfos family of high-quality circulator pumps.

With a MAGNA3, you can stop worrying about complicated pump settings. Simply install the pump and leave it on the factory setting, AUTOADAPT (MAGNA3 only).

The TinyTech 2 KW Solar Water Pumping system is fully automatic with an expected lifespan of 20 years.The cost includes solar panels, support structure, inverter and submersible pump, but does not include pipelines and cables.

Each solar panel is of 250W and is approved by MNRE and is made of first grade polycrystalline solar cells. The size of panel about 1.5m x 1m and each solar panel is supplied with test certificate. Each inverter controller converts DC power of low voltage to AC power of high voltage of 400V. 3 phase power.

Energy conversion for water pumping.Technology consists of rotary blades to convert the wind energy into mechanical energy for water pumping. Blades are designed in relation to the energy desired to pump the water about 2-3 meters long. The switching on and off is done manually to pump the water but intends to use a floater in automation. Device can pump 6000 liters per 8 hours of good wind.
