  • Domestic wastewater treatment: Summary and advantages

    The scarcity of water for present gen is not new for any of us. In spite of the fact that water encompasses the one-third of the entire world, yet least of that percentage is appropriate for drinking. With water deficiencies tormenting the world, water lack has ended up one of the biggest risks confronting society today. While the deficiency of safe drinking water is occurring to be a serious ...

  • A short guide to industrial wastewater treatment

    While the sources of wastewater are kept on creating issues for human society, the shortage of drinking water also lagged on behind it. The scarcity of drinkable water is the most severe issue that is the society is confronting today. Though we love in a society whose 1/3rd% lands are acquired by water, yet the sources of drinkable water are limited. But thanks to the modern technology that has ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters

    The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...

  • Winery and distillery wastewater treatment by anaerobic digestion

    ABSTRACTAnaerobic digestion is widely used for wastewater treatment, especially in the food industries. Generally after the anaerobic treatment there is an aerobic post-treatment in order to return the treated water to nature. Several technologies are applied for winery wastewater treatment. They are using free cells or flocs (anaerobic contact digesters, anaerobic sequencing batch reactors and ...

  • Effectiveness of Alternative On-Site Wastewater Treatment Technologies

    ABSTRACT New York City’s drinking water supply is threatened by the potential development of the Catskill/Delaware watershed. The effectiveness of alternative on-site wastewater treatment systems in this drinking water supply watershed is being evaluated during the course of a oneyear field study. Twenty-four on-site systems were designed and installed for individual sites throughout the ...

  • Classification of contaminants and treatability evaluation of domestic wastewater

    Long-term sampling and analysis were conducted in a domestic wastewater treatment plant for the investigation on the characteristics of the representative contaminants in raw sewage such as SS, COD, BOD5, TP, and TN. All these constituents were classified into dissolved and suspended groups by using a 0.45-μm membrane filter, and the concentration of each constituent in each group was ...

  • Performance of horizontal flow roughing filter using limestone media for the removal of turbidity, suspended solids, biochemical oxygen demand and coliform organisms from wastewater

    This paper examines and evaluates the removals of turbidity, suspended solids, BOD and coliform organisms from wastewater using different sizes of limestone roughing filter. Results indicated that removal efficiencies depended on the size of the filter medium and applied flow rates. Turbidity, suspended solids, BOD and coliform organisms removals were between 75% and 92%, 79% and 88%, 51% and 67% ...

  • Treatment of domestic wastewater by a hybrid natural system

    The present study addresses performance evaluation of a hybrid natural system comprising of settling tank, sand-gravel filter (SGF), aerated constructed wetland (ACW) and vermifilter (VF) for the treatment of domestic wastewater. The sequential batch experiments were conducted in a pilot-scale experimental set-up. The biochemical oxygen demand (BOD5) was varied from 20 to 120 mg/L and the ...

  • Research on the treatment of oily wastewater by coalescence technology

    Recently, oily wastewater treatment has become a hot research topic across the world. Among the common methods for oily wastewater treatment, coalescence is one of the most promising technologies because of its high efficiency, easy operation, smaller land coverage, and lower investment and operational costs. In this research, a new type of ceramic filter material was chosen to investigate the ...

  • Simulation of sludge dewatering on belt filters

    A mathematical model for belt filters was developed to determine optimum load rate and belt speed during drainage of flocculated biological sludge. Numerical simulations were performed for belt filters with and without plows, and the model fit experimental data well. Experiments showed that highly compressible cakes were formed during drainage, which was important. Due to cake compression, the ...

  • 5 Top advantages of MBBR wastewater treatment

    Wastewater treatment solutions have become one of the significant moves to filter waste water. Whether it is for fighting with the growing shortage of drinking water or finding better water sources for wastewater, several technologies have been practice for centuries, and MBBR wastewater treatment is being used for filtering waste water in both ...

  • 4 Top advantages of wastewater treatment solutions

    Getting clean and purified water in current time is sparse. Lack of water has ended up being the harshest circumstance confronting by the present society. Lack of drinking water is kept on affecting every continent, and approximately 1.2 billion people are suffering from the heavy shortage clean drinking water. While the world is moving towards digitalisation at a faster pace, more than billions ...
