Industrial water Ammonia & Arsenic removal from water

Nitrogen is a nutrient essential to all forms of life as a basic building block of plant and animal protein. Nevertheless, too much of it can be toxic. The processes used for the removal of ammonium ions from drinking waters include ion exchange. PuriTech`s ION-IX system can be broken up into 4 distinctive zones with each zone operating continuously. The resin is initially loaded with the Ammonia ions (and partially calcium and magnesium)in the adsorption zone. As the ION-IX multi-port valve rotates, the resin that has been saturated with Ammonia ions (and some calcium and magnesium ions)moves into a one-bed displacement zone with softened water to ensure hard water does not cause precipitation within the multi port valve.

Air pollution control solution for the Ammonia and odour

Control of emissions is often required due to the hazardous nature of the contaminant. Often, control or removal is necessary due to offensive odours. Ammonia, sulfur and other related compounds fall in these categories. Macrotek offers many control technologies to capture ammonia and other odour causing contaminants. Reagents are often used to neutralize and stabilize the by-product.

Water Treatment Solutions for Nitrate Removal

Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. According to the Toxics Release Inventory, releases to water and land totaled over 112 million pounds from 1991 through 1993.

Landfill Leachate Treatment

Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen. Certain processes also produce residues such as concentrates, which must be removed from the landfill body. This disposal is very expensive. WEHRLE is a reliable and experienced plant constructor for those applications. The first leachate treatment plants were built in 1991 and have been in constant operation ever since. This is not only proof of excellent technology but also for sustainable efficiency with stable, predictable, low operation costs.

Disposal wells treatment for oil and gas industry

Treating the water being injected for disposal is not always considered by operators. This is likely costing you money in the long run. Removing iron, heavy metals, and treating out ammonia is a benefit to treating with MIOX’s mixed oxidant solution. While these are benefits of the technology, the most important is the elimination of bacteria which can cause Hydrogen Sulfide (H2S), corrosion pitting, poor injectivity and other problems, resulting in great well workover frequency. Treating injection wells does not need to be expensive, and can be treated as you inject.

Odor Scrubbers Applications with Hydrogen Peroxide

Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.
