REVERSE OSMOSIS STAGE VS PASS A “pass” shall be seen as a stand alone RO system . The difference between a single pass RO system and a double pass RO system is that with a double pass RO, the permeate from the first pass becomes the feed water to the second pass (or second RO) which ends up producing a much higher quality permeate because it has essentially gone throughtwo RO systems.

Colloids are very low diameter particles which are responsible for the turbidity or the color of surface water. Because of their very low sedimentation speed the best way to eliminate them is the coagulation-flocculation processes. The aim of the coagulation is to destabilize the electrostatic charge in order to promote the colloidsmeeting.
MOLECULAR WEIGHT CALCULATOR (MOLAR MASS) Molecular mass or molar mass are used in stoichiometry calculations in chemistry. In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu". PROPERTIES OF GROUNDWATER Properties of groundwater. Composition: The geological nature of the soil determines the chemical composition of the groundwater. Water is constantly in contact with the ground in which it stagnates or circulates, so equilibrium develops between the composition of the soil and that of the water: i.e. water that circulates in a sandy or granitic substratum is acidic and has a few minerals.

ACCURACY-WATER-ANALYSIS This calculator helps you determine the accuracy of your water analysis. The calculations are based on the principle of electro-neutrality. The principle of electro-neutrality requires that the sum in eq/L or meq/L of the positive ions (cations) must equal the sum of negative ions (anions) in solution, thus: BOILER WATER CONSUMPTION The water consumption consists on the control of the make-up water, the blowdown water and the condensed water quantities. These three waters determine the cycles of concentration that can be reached inthe cooling tower.
SAR HAZARD OF IRRIGATION WATER Sodium hazard of irrigation water High sodium ions in water affects the permeability of soil and causes infiltration problems. This is because sodium when present in the soil in exchangeable form replaces calcium and magnesium adsorbed on the soil clays and causes dispersion of soil particles (i.e. if calcium and magnesium are the predominant cations adsorbed on the soil exchange complex, the WATER TREATMENT AND PURIFICATION Lenntech Water Treatment solutions is a design and manufacturing company serving numerous industries.

Reverse osmosis (RO) is a water treatment system that eliminates most dissolved elements and chemicals, such as sulfate, from water by pushing the water through a plastic surface similar to cellophane known as a "semipermeable membrane." Generally, it can eliminate between 93 and 99 % of the sulfate in drinking water. This depends onthe type of unit.

ELECTRODIALYSIS REVERSAL (EDR) 2) Process Function. Fig.1, Schematic description of the electrodialysis reversal process. In each EDR stack there are two electrodes on the outer side which are submerged in a watery salt solution that is able to conduct electrical current and allows for an electrical field to be placed around the stack.SCALING IN BOILERS
Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating.

If we consider that we want to produce pure water from the salt water, it is necessary to apply a “force” (pressure) in the column of the salt-containing water, to force the water to flow in the reverse direction, making the water molecules to flow through the semi-permeable membranes to the fresh water compartment.

SILICA SCALING IN BOILERS Silica, in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies.In rain hail and snow, silica content range from 1 to 2.8 ppm. In the analyses of various surface and ground waters, silica content range from 1 to 107 ppm.This refers to soluble silica content and not to the silica that may be present in thesuspended matter.

Scaling mechanism is the exceeding of theSULFATES - LENNTECH
Reverse osmosis (RO) is a water treatment system that eliminates most dissolved elements and chemicals, such as sulfate, from water by pushing the water through a plastic surface similar to cellophane known as a "semipermeable membrane." Generally, it can eliminate between 93 and 99 % of the sulfate in drinking water. This depends onthe type of unit.
COOLING TOWER BLOWDOWN Cooling tower blowdown (CTBD) treatment. The make-up water Cooling tower blowdown water treatment presents several challenges due to the high salt concentrations and SILICA SCALING IN BOILERS Silica, in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies.In rain hail and snow, silica content range from 1 to 2.8 ppm. In the analyses of various surface and ground waters, silica content range from 1 to 107 ppm.This refers to soluble silica content and not to the silica that may be present in thesuspended matter.
MICRO FILTRATION AND ULTRA FILTRATION The principle of micro filtration and ultra filtration is physical separation. The extent to which dissolved solids, turbidity and microrganisms are removed is determined by the size of the pores inthe membranes.
ACCURACY-WATER-ANALYSIS This calculator helps you determine the accuracy of your water analysis. The calculations are based on the principle of electro-neutrality. The principle of electro-neutrality requires that the sum in eq/L or meq/L of the positive ions (cations) must equal the sum of negative ions (anions) in solution, thus: REVERSE OSMOSIS STAGE VS PASS A “pass” shall be seen as a stand alone RO system . The difference between a single pass RO system and a double pass RO system is that with a double pass RO, the permeate from the first pass becomes the feed water to the second pass (or second RO) which ends up producing a much higher quality permeate because it has essentially gone throughtwo RO systems.
PHOSPHOROUS REMOVAL FROM WASTEWATER Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters. Its presence causes many water quality problems including increased purification costs, decreased recreational and HYDROGEN PEROXIDE AS A DISINFECTANT Lenntech (European Head Office) Distributieweg 3 2645 EG Delfgauw The Netherlands Phone: +31 152 610 900 fax: +31 152 616 289 e-mail: info@lenntech.com Lenntech USA LLC (Americas) BRINE DEEP WELL INJECTION During the well operation there’s a continuous monitoring of brine flow and the wellhead pressure. Increasing pressure during steady operation could indicate possible clogging, while a sudden decrease in pressure is indicative of leaks within the casing, grout, or seal.
