Microfiltration is a way of removing contaminants in the size range of 0.1 to 10.0 µm from fluids or gases by passage through a microporous medium such as a membrane. There are two techniques used in microfiltration: dead-end filtration, where microfiltration is widely used, and cross-flow filtration, using a tangential flow for the fluid being filtered. Larger colloidial particles, bacterial iron, bacterial reduction, algae, and limited viruses typically 5 microns to .1 micron. Nominal and Absolute ratings. Validated upon request.
Nanofiltration is a process similar to microfiltration. Hardness reduction, TOC, VOC, endotoxin, pyrogen and soluable salts typically .01 to .001 micron.
Ultrafiltration is a process similar to microfiltration. The main difference is the "tighter" retention behavior: the ultrafiltration membrane retains much smaller particles from the passage through the membrane than do microfiltration membranes. Typically the particle size is measured by molecular - weight, and ultrafiltration membranes have retention ranges from 1,000 to 1,000,000 molecular weight. Excellent colloidal reduction, viruses, endotoxin, pyrogen, and VOC and TOC reduction typically .1 to .05 mircrons. Comes in “Dead End” or Crossflow configurations.
Electrodeionization Technology (EDI)
Remove residual salts and other aqueous species from your water with up to 18 MOhm-cm resistivity GE’s E-Cell* electrodeionization (EDI) technology removes residual salts and ionizable aqueous species - such as carbon dioxide, silica, ammonia and boron - from your water sources. The EDI systems operate chemical-free, achieve 97% water recovery, and consume only electricity. They are ideal for multiple applications including: power generation for boiler feed and NOx control, semiconductors, microelectronics, food and beverage, and pharmaceuticals.
Electrocoagulation (EC), is a rapidly growing area of wastewater treatment, less well known as radio frequency diathermy or short wave electrolysis, is a technique used for wash water treatment, wastewater treatment, industrial processed water, and medical treatment. Electricity-based electrocoagulation technology removes contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum hydrocarbons, refractory organics, suspended solids, and heavy metals. There are many brands of electrocoagulation devices available and they can range in complexity from a simple anode and cathode to much more complex devices with control over electrode potentials, passivation, anode consumption, cell REDOX potentials as well as the introduction of ultrasonic sound, ultraviolet light and a range of gases and reactants to achieve so-called Advanced Oxidation Processes for refractory or recalcitrant organic substances.
Advanced oxidation processes (AOPs) in a broad sense, refers to a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and waste water by oxidation through reactions with hydroxyl radicals (·OH). In real-world applications of wastewater treatment, however, this term usually refers more specifically to a subset of such chemical processes that employ ozone (O3), hydrogen peroxide (H2O2) and/or UV light. One such type of process is called in situ chemical oxidation.
We provide anion resin dealkalizers with or without caustic feed for boiler water pretreatment. Systems can be duplex, triplex or quadplex depending upon flow capacity required. Turnkey engineering and water treatment/purification systems where dealkalizers, works with deionization, filtration, water softening, reverse osmosis, and ultraviolet instrumentation.
Dealkalization is a process of surface modification applicable to glasses containing alkali ions, wherein a thin surface layer is created that has a lower concentration of alkali ions than is present in the underlying, bulk glass. This change in surface composition commonly alters the observed properties of the surface, most notably enhancing corrosionresistance.
Many commercial glass products such as containers are made of soda-lime glass, and therefore have a substantial percentage of sodium ions in their internal structure. Since sodium is an alkali element, its selective removal from the surface results in a dealkalized surface. A classic example of dealkalization is the treatment of glass containers, where a special process is used to create a dealkalized inside surface that is more resistant to interactions with liquid products put inside the container. However, the term dealkalization may also be generally applied to any process where a glass surface forms a thin surface layer that is depleted of alkali ions relative to the bulk. A common example is the initial stages of glass corrosion or weathering, where alkali ions are leached from the surface region by interactions with water, forming a dealkalized surface layer.
A dealkalized surface may have either no alkali remaining or may just have less than the bulk. In silicate glasses, dealkalized surfaces are also often considered “silica-rich” since the selective removal of alkali ions can be thought to leave behind a surface composed primarily of silica (SiO2). To be precise, dealkalization does not generally involve the outright removal of alkali from the glass, but rather its replacement with protons (H+) or hydronium ions (H3O+) in the structure through the process of ion-exchange.
