Over the last thirty years, the Aquaculture industry has seen tremendous growth worldwide. Now, US producers are struggling because international suppliers are flooding the domestic market and driving prices down. Recently, the industry has been turned upside down with the introduction of the bio-floc technology. The underlying principle of the bio-floc technology is to create an environment that is “biologically” dominated, as opposed to the traditional system of allowing algae to be the primary...

The largest volume effluents in petroleum refining include “sour” process water and non-oily/non-sour but highly alkaline process water. Sour water is generated through a number of processes, such as: - Desalting - Topping - Vacuum distillation - Pretreating - Light - Middle distillate hydrodesulphurization - Hydrocracking - Catalytic cracking - Coking - Visbreaking/thermal cracking Sour water may be contaminated with hydrocarbons, hydrogen sulfide, ammonia, organic sulfur compounds, organic acids, and phenol....

Companies and municipalities have to remove nutrients from their effluents - such as nitrogen and phosphate - before they can reuse the water. There are also strict discharge limits on the nutrients levels that must be met. Paques has a number of technologies that can deal with these requirements.

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.

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...

Over the last 30 years, nutrient pollution has become one of the major issues threatening the water ways around the U.S. Severe algae blooms and the corresponding hypoxic zone are a problem that will not go away alone. The U.S. EPA has been aggressively working with state regulators to limit the amount of point-source nutrient pollution around the country, and particularly in sensitive watersheds such as the Chesapeake Bay and the Mississippi River. Unfortunately, the amount of pollution from non-point source...

There are over 307 million lakes in the World and that doesn’t even take into account man-made lakes or reservoirs and the majority of those are only 2.5 acres. Lakes are open systems and capture tons of organic material including trash, run-off, airborne debris, and algae. Most of the lake pollution occurs from human activity so it’s up to us to fix it. That’s why BCMbio™ has developed a complete line of lake management solutions to clean up even the most polluted body of water.

PLAZKAT Aero units are used to neutralize bad smells from waste treatment facilities, caused by the presence of sulfur and nitrogen compounds - hydrogen sulfide, mercaptans, and ammonia. Urban waste treatment facilities, local waste treatment systems in factories, pumping stations in waste water treatment systems are characterized by a strong smell of sulfur and nitric compounds.

Fine filtration is essential to help maintain water quality when pumping out source water directly to fish tanks or in recirculating or closed loop systems in commercial aquaculture systems. Recirculating water systems are very common and used to minimize or reduce dependence on water exchange and flushing in fish culture units.

Coke Wastewater Treatment: Heating coal over 1100 Co in the absence of oxygen produces metallurgical coke. This process provides both heat and carbon (coke) required for iron production. During this process the volatile materials contained in the coal are driven off, leaving coke as the product. Gas produced by coking is withdrawn by means of blowers to recover energy-rich byproducts, including methane. Ammonia stills are the principal means of recovery. Recycled scrubber water is used as a coolant. Scrubber...

Zirconium phosphate compounds are emerging as critically important reagents in hemodialysis home treatment units for kidney patients. Zirconium phosphate is also used in the ceramics industry for color and strength application, as well as a catalyst for petroleum industry application. You can also find zirconium phosphate in paints and coatings, anti-bacteria and artificial joints, and optical material application.

Industrial wastewaters are often produced on extremely large volumes. Many studies have shown that these wastewaters can potentially serve as a source for both carbon (essential nutrient) and water for microalgal production. The effluent of an anaerobic internal circulation (IC) reactor, used to treat the waste of a biotechnology production facility, was chosen as the cultivation medium for Chlorella sorokiniana in batch and continuous cultures using the PBR101 photobioreactor.

Air Stripping is the transferring of volatile components of a liquid into an air stream. This process is used for the purification of groundwater and wastewater containing volatile compounds. Air Strippers are usually packed towers operated with a countercurrent flow of water and air. The design for Air Strippers involves a packed tower which includes plastic random packing it its design. The size of the packed tower and plastic random packing is determined by the air to water flow rates. Since many of the...

Enhanced Oil Recovery (EOR) is a broad O&G Industry term, but almost always involves some kind of water treatment processes. Whether you are trying to increase injectivity, kill bacteria, break emulsions or destroy polymers, MIOX has equipment to help. MIOX’s exclusive Mixed Oxidant technology turns your EOR site into an on-demand chemistry factory - eliminating middle men and lowering costs.

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...
