TECHNOLOGY
Water purification is the removal of contaminants from raw water to produce drinking water for human consumption or industrial use. Water filtration by means of a sand filter is use to remove suspended solids from water. The filtration media consists in silica sand, anthracite, gravel. An activated carbon filter reduces organic materials and other contaminants than can cause taste and odor problems in water. Final disinfection is made by using chlorine dosing, ozone or UV light.
FILTRATION ANDPURIFICATION TECHNOLOGY
Microfiltration is a physical filtration process where water is passed through a pore size membrane to separate suspended solids and microorganism. The typical particle size used for microfiltration ranges from about 0.1 to 10 μm. This process is used generally as a pretreatment of reverse osmosis systems.
MICROFILTRATION MF QUALITY
Reverse osmosis is the process of forcing water from a region of high solute concentration through a semi permeable membrane to a region of low solute concentration by applying a pressure in excess of osmotic pressure. RO membranes are made of a thin film composite polyamide and rejects contaminants based on their charge and size. This water technology is capable of removing up to 99% of the dissolved solids, colloids, organics, bacteria (particles larger than 0.0001 microns. RO works with a high pressure pump, the more concentrated is the feed water the more pressure is required in the system.
REVERSE OSMOSIS RO INTELLIGENTSOLUTIONS
Biological wastewater treatment is the conversion of biodegradable waste products from domestic, municipal or industrial sources by biological means. The treatment process consists of the following stages: Primary Treatment – It is the first stage of the treatment and is designed to remove solid objects, suspended and floating solids from raw water. Secondary (Biological) Treatment - Removes the dissolved organic matter that escapes primary treatment. This is achieved by microbes consuming the organic matter as food, and converting it to carbon dioxide, water, and energy. Tertiary Treatment - Can remove more than 99% of all the impurities from sewage, producing an effluent of almost drinking-water quality.
WASTEWATER TREATMENT PLANTS TREATMENT BY EXPERTS
Reverse Osmosis is the most widely practiced desalination technology. In this technology seawater is forced against semipermeable membranes under high pressure (>700 psi). As the water permeates through the membrane the 99.5% of the dissolved salt is removed. SWRO systems are designed to keep down energy consumption using high efficient pumps, low energy membranes and energy recovery systems such as Pressure Exchanger and Turbine.
SEAWATERDESALINATION INNOVATION
Ultrafiltration is a membrane filtration which retain suspended solids, solutes of high molecular weight, colloids, bacteria and viruses. UF membranes have a pore size between 1 - 100 nm. There are 4 configurations of UF membranes: spiral wound, plate and frame, tubular and hollow fiber. UF reduces the silt density index and removes particles that can foul reverse osmosis membranes and is frequently used to pretreat surface water, seawater and biologically treated municipal water upstream reverse osmosis.
ULTRAFILTRATION PRE - TREATMENT AND BREACH OF WATER OIL EMULSIONS
Electrodeionization is a water purification technology that utilizes electricity to removes residual salts and ionizable aqueous species and produces up to 18 MOhm-cm resistivity water for applications including Power Generation, Pharmaceutical and Microelectronics. In this process water is passed between a positive electrode and a negative electrode. Semi permeable ion exchange membranes separate the positive and negative ions creating deionized water. EDI operates chemical free which eliminates expensive and hazardous chemicals used in ion exchange resin regenerations. EDI modules are usually used as a post treatment of RO water.
ELECTRODEIONIZATION EDI MAXIMUM PURIFICATION OF WATER
Membrane Bioreactor process is a combination of biological wastewater treatment and membrane filtration and is used for municipal and industrial wastewater treatment. Biodegradable pollution is reduced using bacteria and microorganisms. Following biological treatment, the activated-sludge is separated from the treated water by a microfiltration membrane. Membranes can be flat sheet or hollow fiber. There are two configurations: internal-submerged and external-sidestream. MBR can produce a high quality effluent to be discharged to drain, water source or to be reclaimed for irrigation.
MBR MEMBRANE BIOREACTOR PROCESS
Ion Exchange Demineralization is the process of removing mineral salts from water by using ion exchange resins. Ion exchange resins are small plastic beads that are composed of organic polymer changes and attracts charged ions. Eventually, when the resins beads are exhausted is needed to be regenerated with acid/alkaline solutions. Ion exchange produces ultrapure water.
ION EXCHANGE DEMINERALIZATION MODERNITY
Nanofiltration is a membrane based filtration using 1 to 10 nm pore size membranes. NF technology is used as a softening (polyvalent cation removal) in surface water and ground water. The feed pressure to NF systems generally is lower than RO systems because uses bigger pore size membranes. Typical applications of NF systems are softening, heavy metal removal and salt reduction in low dissolves solids brackish water.
NANOFILTRATION EQUIPMENT AND INNOVATIVE TECHNIQUES
Physicochemical treatment of wastewater focuses on the separation of colloidal particles, heavy metals, oil and fat and floating parts by adding coagulants and flocculants chemicals. Coagulant causes the destabilization of contaminants by the reduction of surface charges responsible of particle repulsions. Flocculants produces the agglomeration of particles that will settled and a clarified effluent is obtained.
PHYSICOCHEMICAL PROCESSES COMMITMENT ON WATER QUALITY
Degasification consists in forcing air up-flow over a thin film or small drops of down-flow water. This procedure allow gases such as carbon dioxide and hydrogen sulfide to escape to the moving stream of air. The system has three main components: a packed tower, a blower and a sump. The tower is filled with a large surface area packing that breaks up the falling column of water into a thin film and small drops. The blower forces a stream of air upflow through the water and out through the vent pipe. The sump receives the degasified water and stores it for a few minutes before it is pumped to the point of use.
