HYWATER Reverse Osmosis plant/system
water Treatment unit by reverse osmosis with a capacity of 50m³per day What are the conditions that Tunisia needs before installing water treatment equipment? Then I will sort it out for you with the case of our company: The Supply, installation and commissioning of a reverse osmosis plant with a capacity of 50 m3 per day at 1000 ppm for drinking water for bovine animals Supply of a water treatment unit deep drilling. That unit must be composed by:Raw drilling water has a high iron content and high turbidity, so in order to prevent the formation of iron carbonate and to ensure optimum equipment durability, pre-treatment of the raw feed water is essential to remove deposits and reduce fouling. The quality of the raw water is summarized in the following table: The above mineral solutions mainly include the following: Pretreatment stage: It is important to propose the required treatment facilities for the desalination plant, depending on the quality of the raw water, and to ensure that it is of good quality for drinking water for bovines Filtration step: Automatic filtration is essential: a sand filter and cartridge filters. Injection of sequestrants: The sequestrant injection station contains a polyethylene storage tank and will be equipped with a system level reading, stirrer for possible dilution of sequestrant, of a detector of level. with generation alarm And transmission of signal At PLC And a emptying connected to the desalination plant discharge system, two dosing pumps including one is a backup and also a sequestrant injection system with a detector of debit allowing of to provoke the stop of the unit of desalination At case Or this one born would detect more flow. The sequestrant will be injected downstream of the micro-filter. Osmosis block: High pressure pumping Purification part : Membrane ▪Regarding the production of first-stage permeate. ▪ Regarding the production of second stage permeate. ▪ Regarding second-stage denials. An iron and manganese abatement system: This system must ensure that the iron and manganese content is reduced to values acceptable to the membranes of the new reverse osmosis plant. The iron removal and demanganization operations must be carried out separately (in cascade). And all the necessary equipment must be provided to perform the two operations separately such as: - An air injection kit for oxidation and an electric dosing pump with agitator tank for demanganization. - HD polyamide tanks with epoxy treatment inside. - Cartridge filters, sand filters, multimedia filters .... - Automatic counter-current washing machines with the possibility of manual of the washing. - Control panels (including pilot solenoid valves, pneumatic valves for washing, control manometers, etc.). The injection of these agents will be controlled by the water flow at the outlet of the pumps. The dosing system is complete with the necessary accessories for the correct functioning of the operation (bottom valve, level probe, injection valves etc.) The chlorine dosage must be precise to avoid oxidation of the membrane material even after dechlorination. B-Reverse osmosis desalination station The water will go through three chemical injection operations which are : - Upstream of the 5 micron filter door, sodium metabisulfite will be injected to perform dechlorination. - The injection of an anti-scalant product downstream of the 1 micron filter gate to avoid the precipitation of iron oxides and the calcification of osmotic membranes. - The injection of liquid soda concentrated at 10% so that the water mixture is balanced (neither corrosive nor incrusting). This injection will be done in a mixing chamber in which a pH probe will be placed.

A coagulant-flocculant injection system (2x100%): A chlorine injection system to fight against biofouling: A chemical injection stage (dechlorination / anti-scalant / pH adjustment): This injection stage will be mounted on a stainless steel frame and will be composed of three (03) electromechanical diaphragm dosing pumps, equipped with precise flow control.A tank with a storage capacity of at least 100 L with its agitator will be associated with each pump (03 tanks in total).
