| | | HP ERDUND SERIES HP High Pressure Srl designs and manufactures reverse osmosis plants of small, medium and large dimensions for the desalination of sea water and the treatment of brackish and tap waters. The plants manufactured by HP High Pressure have found application in the followings fields: SEAWATER DESALINATION BRACKISH AND TAP WATER TREATMENT Yachts Houses Houses Hotel Hotel Camping Camping Pharmaceutics industry Chemical industry Hospitals Farms | | |
| | | The plant here described is able to produce by an unique treatment 3 cubic meter of drinking water per hour, using seawater at 35.000 mg/l TDS. The water produced will be characterized by a residual salinity less then 500 PPM TDS. Organic big molecular substances, as viruses, bacteria and pyrogen agents will not pass though membranes. The choice of multiple plants is not casual. By this way we try to avoid every system stop that could happen if I there was installed a single high pressure pumping group. The advantages of this solution are indisputable. It will be possible, for example, the membrane substitution, their ordinary washing by fresh water, and their ordinary washing by chemicals; therefore it will be possible the ordinary pumps and motor maintenance and in case of eventual damages, there will be the possibility to stop just a single unit, avoiding to stop all the multiples. It will be also possible to save the energy needed for the start by a smaller total energetic absorption, in that the pumps could start one by one. The sea water, taken by the low pressure boost pump, will be brought through a sand filter, that will get rid of all the biggest particles in suspension up to 50 micron; this group will be self washing. The following phase will bring the water into a multi cartridge filter group that will detain the particles in suspension up to 5 micron to avoid the obstruction of the R.O. membranes. In the further step, a dosing pump will inject an anti floccu-lent solution to avoid the precipitation on the membrane of the heaviest elements, dissolved in the water. The high pressure pump will push the seawater at 55 - 60 bar into the osmotic membranes. By this pressure the desalination treatment will take place. Through the pressure effects just a pretty small portion of water will pass through the membranes (10%). This will be called permeated water and will be drinking water. The remaining portion, the concentrated water, will be dumped to the sea. | | |
