On this occasion, a Spanish multinational from the metallurgical sector, dedicated to the production of metal profiles and accessories, has placed itself in the hands of J.HUESA to adapt the quality of the water they use to treat the surfaces of the parts they manufacture in the center. production located in Algeria. J.HUESA has carried out the study, design, manufacture and commissioning of a water treatment plant whose objective is to eliminate the salinity of the water supplied to rinse baths by means of reverse osmosis .

The installation, made up of a reverse osmosis plant with a previous filtration, has the capacity to produce a total of 8 m 3 / h of osmotized water. This must be stored in a 30 m 3 capacity warehouse . Osmosis is made up of two stages. So the rejection of the first is introduced into the second. With the particularity of being able to clean the stages independently. Facilitating in this way the maintenance of the plant. The installation has a conversion between 65% and 75%.

The water from the well that feeds the installation, previously passes through a low speed bilayer filter and automatic washing. In which the solids in suspension that can be dragged by the water are retained. Before entering the reverse osmosis membranes, the water passes through a 5µ safety prefilter and chemical products are dispensed (reducing agent, antifouling and sequestering agent). For the adequacy of the affluent with the consequent increase in the performance of the membranes. The parameters of the water that circulates through the plant are measured with measuring equipment (conductivity, redox, pH). And controlled by a Siemens automaton programmed by specialists in this sector.

The main advantages of this installation are the following:
1. The system works continuously, without the need for regeneration, eliminating the consumption of products that are difficult to handle. home water purifier in bd

2. The system is fully automatic, it can work up to 24 hours a day, with minimal supervision. It does not require personnel with special qualifications.

3. The reverse osmosis system assumed due to the characteristics of semi-permeable membranes. A bacteriological barrier in the produced water, which eliminates bacteriological problems in the installation.

4. There are no toxic, dangerous or polluting discharges to the environment. Expendables are in short supply.
