Excessive algae growth can throw even the best water treatment processes out of balance. Algae can clog intake screens, fluctuate pH levels, increase chlorine demand, and negatively affect the taste and smell of water. By blocking sunlight within water treatment tanks, you can stop algae growth, reduce chemical usage, and minimize the formation of disinfectant by-products (DBPs). Temperature is better controlled and maintenance associated with algae cleaning is simplified. The results? Better water treatment and lower operating costs.

Whether you find yourself in a hotel bath room, cruise ship cabin, hospital, office building, industrial plant, greenhouse, car wash facility or your own hot tub, the combination of certain temperature levels, stagnant water and the presence of biofilm in water systems is a potential recipe for disaster: an outbreak of Legionnaires’ disease. An outbreak of Legionnaires’ disease is often the result of negligence, having legal repercussions for responsible parties. Because of its chemical and biocidal characteristics, chlorine dioxide is ideal for maintaining good standards of water hygiene. Chlorine dioxide has consistently been demonstrating to be the best molecule for eradicating the causative organism of Legionnaires’ disease.

In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

In order to ensure that an industrial process can be controlled or even improved and optimized continually an analysis of the current situation in real time is necessary. Process data like temperature, pressure but also particle concentration and size distribution of a material flow can supply valuable information and be used for the regulation or the improvement of a process.

“Efficiently lowers algae, biofilm formation, bacterial counts and chemical consumption.” When temperatures are high, for example in cooling towers, a matrix of different microorganisms such as bacteria, fungi, EPS and algae can grow very rapidly. The disadvantages of biofilm formation in cooling towers can be enormous. Therefore water used in cooling towers needs frequent treatment and chemical shocks to keep levels of micro-organisms to a minimum.

teel and ferrous alloys production happens in industrial manufacturing processes which involve high temperature exhaust streams, often at more than 900 ºC. Typically, the gas flows into a gas conditioning tower to cool down to approximately 200 ºC, before entering into an ESP. These flue gases from steel or ferrous alloys kilns are also very maintenance demanding for bag filters and the very small size of the particles limit the use of usual dedusters such as regular cyclones and multicyclones as pre-separators. Bag filter failure is consequently a very common problem for clients in this industry. 

Client`s needs include a very robust dedusting system, either serving as end-stage collector avoiding the need to cool down flue gases, or strongly minimizing the loads of aggressive material to bag filters.

Waste incineration is a complex area. The mix of waste, moisture content, temperature of the waste, surrounding air and a variety of other factors interact and affect which residues are formed. Combustion entails often a gas consisting of heavy metals, sulfur oxides, chlorides, dioxins, etc. It is extremely important with a proper handling of the gas and the task often requires a mixture of wet and semi-dry treatment. EnviBAT offers equipment that brings particle levels down to extremely low levels, which guarantees a total separation of dioxins and wet purification that separates contaminants found in the gas phase.

Compressed air isn`t free, so more and more companies carefully monitor its usage. Thermal flow meters are ideal for this application. Because our thermal flow meters measure mass flow directly, no temperature or pressure compensation is required. Thermal flow meters also have a very high turndown, allowing the same flow meter to measure very low leak rates as well as full operational flows.

For PM emission control in high temperature exhaust streams, such as fuel oil boilers, usual dedusters such as bag filters are very maintenance demanding. Particularly, diesel and fuel particulates are very sticky and clog to filter elements, unless protection reagents are used. Flue gas cooling is also needed in front of the filter when temperatures are higher than 200 ºC. On the other hand, regular cyclones and multicyclones are frequently not able to reduce emissions to present emission limits.

Hydrogen Peroxide typically controls odors and corrosion at treatment plant headworks by direct oxidation of hydrogen sulfide (H2S) within the wastewater. In the direct oxidation mode, H2O2 is applied to the wastewater 5-30 minutes prior to the point where the odors are being released, generally as the wastewater line enters the plant boundary. The efficiency of hydrogen peroxide treatment depends upon the available reaction time, the level of iron in the wastewater (reaction catalyst), wastewater pH and temperature, and the initial and target levels of H2S odor. Under optimal conditions, effective dose ratios are 1.2 - 1.5 parts H2O2 per part dissolved sulfide, and can be reliably estimated through beaker tests. H2O2 + H2S → S0 + 2H2O Frequently, control of odors through the primary clarifiers is wanted. In such case, the mechanism of control is both direct oxidation of H2S (as it rises from the solids blanket), and prevention of odor generation (by supplying dissolved oxygen). Control is typically achieved with a booster dose of 1-2 mg/L H2O2 added to the clarifier influent. Higher doses or alternate modes of addition may be required in cases where: 1) hydraulic retention times are > 2-3 hours; 2) solids blanket depths are > 1-2 feet; 3) soluble BOD levels are > 200-300 mg/L; or 4) waste activated sludge is co-settled with the primary solids. 2H2O2 → O2 + 2H2O
