  • 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 ...

  • 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 ...

  • Anaerobic Reactor Design Concepts for the Treatment of Domestic Wastewater

    Since the earlier anaerobic treatment systems, the design concepts were improved from classic reactors like septic tanks and anaerobic ponds, to modern high rate reactor configurations like anaerobic filters, UASB, EGSB, fixed film fluidized bed and expanded bed reactors, and others. In this paper, anaerobic reactors are evaluated considering the historical evolution and types of wastewaters. The ...

  • Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges

    The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

  • A Submerged Attached Growth Bioreactor for Decentralized Wastewater Treatment

    ABSTRACTThe Amphidrome® process is a submerged attached growth bioreactor (SAGB) that has been used in Massachusetts, Connecticut, Rhode Island and New Jersey for decentralized wastewater treatment systems ranging in size from 440 gpd to 150,000 gpd. The two primary advantages of a SAGB are the small volume requirement and the elimination of downstream clarification. Five years of data from four ...

  • Oxygen Transfer in a Biological Aerated Filter

    The City of San Diego (City) operates the Point Loma Wastewater Treatment Plant (PLWTP) which can normally treat up to 240 million gallons per day (MGD) of chemically enhanced primary treated (CEPT) effluent for ocean disposal. The City wanted to understand the performance capabilities of Biological Aerated Filters (BAFs) in treating CEPT effluent to secondary standards. To this end, the City ...

  • 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 ...

  • 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 ...

  • Low cost processes for the removal of phosphates in water and wastewater

    This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...
