The presence of hydrogen sulfide in home drinking water supplies is not a health hazard, but is a common nuisance contaminant whose distinctive “rotten egg” odor makes water treatment desirable. Several treatment methods are available, and often hydrogen sulfide can be treated and removed using the same process and equipment used for iron and manganese removal.
Acid mine drainage (AMD) is typically characterized by low pH and high dissolved iron. The acid mine drainage may also contain high amounts of CO2 which forms carbonic acid and further depresses the pH.
The Tarboro Water Treatment Plant, built from 1937 to 1938, serves approximately 14,000 people in Tarboro, NC, as well as some of the surrounding rural areas. Originally, the plant had rapid sand filters with a total capacity of 1.5 mgd. It was upgraded in 1958 increasing the plant’s capacity to 3 mgd. In 1979, the filters were converted to a dual-media consisting of a nine inch layer of filter sand beneath a twenty inch layer of filter anthracite, again doubling the capacity to 6 million gallons per day.
Our Filters are Highly Resistant to Corrosivity. Reverse osmosis is one of the most widely applied desalination technologies. Previous to the process of separtion of water from salt and minerals, seawater or brackish wter requires the elimination of large size particles in order to assure a good performance of reverse osmosis membranes. Our sand filters facilitate the removal of these suspended solids to avoid membrane fouling. In addition, after reverse osmosis process, water has to be remineralized through...
Mining release large volumes of water with a high conductivity due to the mineral salts that it contains. These effluents must be be treated with sand filters or activated carbon filters to reduce the environmental impact. Our range of filters in fiberglass reinforced polyester is highly resistant to corrosion and is, therefore, suitable to withstand these aggresive conditions.
The first use of activated carbon for water treatment dates back to more than 2000 years ago when the product was used in char form. Powdered Activated Carbon (PAC) became commercialized during the 20th century for water treatment to remove taste and odor contaminants. Granular Activated Carbon (GAC) came into use after World War II.
Using any coated abrasive for sanding, polishing, or finishing introduces small amounts of both surfaces into the air. The particle size of the dusts produced in this application depends significantly on the abrasive’s grit size and composition, as well as the material being worked. Wood, metal, or plastics dusts each have specific health risks if inhaled.
Offshore installations, whether it’s a drilling rig, production platform or FPSO, have some of the most testing operating environments possible. Operators must combine the drive to efficiency with their environmental commitments. Whatever analyzer you choose should not only match your needs and add value but must not take up valuable resources whether that’s personnel or consumables.
The food and beverage industry faces many challenges in their manufacturing processes. This industry demands pumps that can provide gentle but reliable pumping action that can meet their highest quality and hygienic standards. ALBIN PUMP peristaltic hose pumps provide superior performance for handling low shear sensitive food products and offers accurate and repeatable metering for additives, flavorings, and colorings and viscous products containing solids. ALBIN PUMP can offer hygienic food grade hoses in...
By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the...
Today ceramic MF/UF membrane filtration for treatment of drinking water is becoming more and more accepted as a viable treatment method. This trends is mainly driven by an increasing demand for a more effective removal of especially challenging feed water containing:
The Sheaf Filter saves water, demands less maintenance and has enhanced filtration as compared with older, ordinary sand filters or diatomaceous earth filters used at public swimming pools today. With an automatic self-rinsing back-wash system utilizing less than 1% of the water from the overall water cycle, the Sheaf Filter reduces water consumption, energy consumption, cuts daily labor cost – (time spent on maintenance), reduces chlorine demand and improves water quality.
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.
All the industries including pharmaceutical, food&beverage, chemical, textil, paper & pulp, etc. require big quantities of water. The water used in any industrial process as for example heating, cooling or if it is going to be consumed directly in the process like in food & beverage industry should be purified and softened. Our range of pressure vessels can treat these effluents through sand, multimedia or activated carbon filters according to the needs.
Nowadays, drinking water is still not available for all the population. The development of mobile units makes possible the supply of drinking water to remote areas. We can design sand filtration systems adapted to specific demands for containerized water treatment plants
Wedge wire screen is divided into: cylindrical screen and flat screens. The cylinder screen mainly composed of V wire and support rod,each cross point connected in welding,solid structure,good mechanical properties.V-shaped cross-section to avoid clogging,while ensuring the smooth flow of water.Continuous slits have a greater flow areas,while reducing ground water penetration speed,avoiding sand under large pressure into the tube,better filtration properties of sand,the gap may be varied depending on the geological...
Controlling algae, cyanobacteria and fouling efficiently with ultrasound to reduce taste and odor problems in the treatment plant. Prevent taste and odor problems. Control fouling in sand filters and clarifiers. Improve coagulation and flocculation processes.
Fossil fuel or solar-thermal power plants require clean water for their operation. Water used may contain several impurities such as calcium, magnesium or silica which can cause damages to turbines or heat exchangers. For this reason, water must be treated by ionic exchange or mechanical filtration. Also, the appropriate wastewater treatment for its reuse through sand filters in order to contribute to a sustainable water use is of vital importance.
