  • Effectiveness of recovered Magnesium Phosphates as fertilizers in neutral and slightly Alkaline soils

    Magnesium phosphates such as struvite (MgNH4PO4 · 6H2O) can be recovered from municipal, industrial, and agricultural wastewaters. However, limited information is available on the beneficial reuse of these recovered products; research has focused on low pH soils. This study determined whether recovered struvite and dittmarite (MgNH4PO4 · H2O) were effective P fertilizers in neutral to slightly ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • 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 ...

  • Characteristic of wastewater and their analysis

    Wastewater containing chromium and other heavy metals, is highly toxic effluents which require high-quality and efficient purification. Such effluents formed during electroplating, other types of chemical, electrochemical surface treatment of metal products such as chromium-plating, nickel-plating, copper-plating, zinc-plating, cadmium-plating and also during some technological ...

  • 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 ...

  • Optimization of motor vehicle industries wastewater treatment methods with the aim of heavy metals removal and water reuse in pilot scale

    Virtues of industrial wastewaters completely depend on the type of process and products of the factory. Keeping this fact in mind, the greatest differences between industrial waste and municipal wastewaters could be as follow:  There is more possibility of existence of toxic chemical compound in the industrial wastewater. - It has more corrosive characteristic.  It conveys alkaline or acidic ...

  • Microbiology: The Key to Wastewater treatment case study

    The biological treatment of wastewater relies mainly on a consortium of heterotrophic and autotrophic bacteria. The fecal bacteria that are constantly introduced into the collection system are not the optimal bacteria for degrading the contaminants present in wastewaters. The soil bacteria that are introduced through inflow and infiltration are more effective at degrading the wastes and can ...

  • 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 ...
