acidic wastewater neutralization Articles

  • White paper - Neutralization theory

    The most common measurement made in water-pollution control, particularly in the area of industrial wastewater treatment, is pH. Acidic and basic substances, which define pH, have a severe effect on aquatic life and, in turn, an effect on humans. Since acids and bases are used extensively in industry, it is important to understand these effects, because pH measurement is the essential key to ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Manganese-catalyzed degradation of phosphonic acids

    Abstract The non-biodegradable and chemically very stable phosphonates are used in a variety of industrial applications including cooling waters, oil production and textile industry. We show here that they are degraded in the presence of Mn(II) and oxygen. The half-life for the reaction is 9 min near neutral pH. The presence of other cations such as Ca(II) and Zn(II) considerably slows down the ...

  • Skimming Oily Wastewater

    As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater. Because ...

  • From Wastewater Treatment to Sweet Pineapples

    In wastewater treatment, ammonia that is removed from sewage used to be discharged directly to the atmosphere. Nowadays, studies have identified that ammonia emissions are of major concern to air quality. This has led to a new way of thinking. Sulzer offers modern closed-air-loop systems for wastewater treatment that transform ammonia into a common soil fertilizer. This reuse of a waste product ...

  • Cavitational technology in wastewater treatment process

    Cavitation is one such recent technique which has been found to be substantially beneficial in wastewater treatment. Cavitation can be described as formation, growth and sub-sequent collapse of cavities releasing large magnitudes of energy locally, creating conditions similar to hot spots, and also generating strong oxidizing conditions by way of ...

  • Grab the best wastewater treatment service provider

    The hazardous organic wastes are immensely increasing by industries, militaries as well as by the domestic sources. It is an emerging issue in the recent days and needs immediate actions by government or by any private organization. To reduce the effects of the hazardous waste from the environment, the advanced oxidation process is considered as an efficient technique that helps in removing ...

  • Wastewater treatment from phenol by AVS-100

    Qualitative treatment of wastewater from phenol and other organic contaminants has a great practical importance within different branches of industry. In many cases, contemporary ways of usage by enterprises do not provide high qualitative treatment (degree of phenol decline is 75-90%). These ways have defects such as long process duration from 3 to 5 hours, long processing time, high reagent ...

  • Pilot test of pollution control and metal resource recovery for acid mine drainage

    The study was undertaken in order to recover the metal resources from acid mine drainage (AMD). A 300 m3/d continuous system was designed and fractional precipitation technology employed for the main metals Fe, Cu, Zn, and Mn recovery. The system was operated for six months using actual AMD in situ. The chemicals' input and also the retention time was optimized. Furthermore, the ...

  • Case study: How to purify Hexavalent Chrome Wastewater

    We all talk about priority pollutants, about hazardous substances and discharge to the atmosphere etc. which are dangerous for our environmental. Day by day we adopt new laws and regulations to protect our green future. So, what is that “priority pollutants”? Priority pollutants are highly toxic chemicals. The list of these chemicals is quite large and includes thousands of items but ...

  • Iron removal in highly contaminated acid mine drainage using passive biochemical reactors

    Passive biochemical reactors (PBRs) are a viable alternative to neutralization plants for the treatment of acid mine drainage (AMD) because they require lower investment costs and use residual materials. However, high iron (Fe) concentrations (≥0.5 g/L) in AMD are challenging for their long-term efficiency. Sorption and precipitation are the main Fe removal mechanisms, but the relative ...

  • Phenol degradation kinetic property in coking wastewater with pulse corona

    The degradation kinetics of phenol in coking wastewater and the effect of electrode parameters on phenol's removal ratio in pulse corona discharge were investigated with experiments and theoretical analysis. The result showed that Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand after five days (BOD5) in the wastewater increased in the initial step, ...
