A bench scale study was carried out in order to evaluate the applicability of dissolved air flotation (DAF) as an advanced treatment for effluents from three different domestic wastewater treatment processes, namely: (i) a tertiary activated sludge plant ; (ii) an upflow sludge blanket anaerobic reactor (UASB); and (iii) a high-rate stabilization pond.

Papermaking Wastewater

The quality of water from traditional two-stage biochemical treatment process of papermaking wastewater cannot meet the pollutants discharge standard of paper industry,therefore it is necessary to develop new advanced treatment processes to further treat the effluent. This paper adopts the homogeneous Fenton oxidation technology to treat the effluent from a secondary sedimentation tank of a papermaking factory by batch experiments. The optimum reaction conditions are H2O2dosage 6.54mmol/L, FeSO4.7H2O dosage 200mg/L, pH=3, t=1.5h and of all the experiments the dosage of polyacrylamide is 3ppm. The COD of the treated water is under 50mg/L and its removal rate can reach as high as 75.4%, the chroma almost falls to zero, the effluent meets the first grade of the national wastewater discharge standard. Therefore, the homogeneous Fenton is an effective alternative for papermaking wastewater advanced treatment, due to its high effect.

The Impact

With an ever-increasing world population and the resulting increase in industrialization and agricultural practices, depletion of one of the world’s most important natural resources, water, is inevitable. Water reclamation and reuse is the key to protecting this natural resource. Water reclamation using smaller decentralized wastewater treatment plants, known as satellite water reuse plants (WRP), has become popular in the last decade. Reuse plants have stricter standards for effluent quality and require a smaller land footprint (i.e., real estate area). They also require additional treatment processes and advanced treatment technologies. This greatly increases the energy consumption of an already energy intensive process, accentuating even more the nexus between energy use and wastewater processing. With growing concerns over the use of nonrenewable energy sources and resulting greenhouse gas (GHG) emissions, WRPs are in need of energy evaluations. This paper contrasts the energy consumption of both conventional and advanced treatment processes in satellite WRPs. Results of this research provide a means for engineers and wastewater utilities to evaluate unit processes based on energy consumption as well as a foundation for making decisions regarding the sustainability of using advanced treatment technologies at reuse facilities.

The Cost

In the Netherlands, interest in advanced treatment is increasing now that almost all wastewater treatment plants apply full biological treatment and nutrient removal. The resulting effluents have an excellent quality which can be improved further by applying advanced treatment processes like flocculating filtration, membrane filtration, UV or activated carbon, and others. The treated effluent can be re-used for various purposes, as process water, household water, urban water, for groundwater suppletion and drinking water. Nowadays many applications are investigated. In order to confirm the applicability pilot test investigations are done at various WWTPs. The results are promising; the cost estimations show increasing prospects. This will finally lead to the maturity of the advanced treatment. It will certainly contribute to a more sustainable water cycle.

Wide Range

Reliance upon advanced water treatment processes to provide safe drinking water from relatively compromised sources is rapidly increasing in Australia and other parts of the world. Advanced treatment processes such as reverse osmosis have the ability to provide very effective treatment for a wide range of chemicals when operated under optimal conditions. However, techniques are required to comprehensively validate the performance of these treatment processes in the field. This paper provides a discussion and demonstration of some effective statistical techniques for the assessment and description of advanced water treatment plant performance. New data is provided, focusing on disinfection byproducts including trihalomethanes and N-nitrosamines from a recent comprehensive quantitative exposure assessment for an advanced water recycling scheme in Australia.

Two Alternatives

With shortage of water becoming a major concern in many areas, use of recycled water is a necessity for a growing number of municipalities. This paper describes a case study in which two alternatives were considered for upgrading an existing wastewater treatment plant with the goal of producing recycled water. The first alternative consisted of conventional secondary and tertiary unit processes while the second alternative included the advanced treatment technology of membrane bioreactor (MBR). Also, two alternatives were evaluated for disinfection of recycled water; chlorine gas and UV system. The more advanced treatment technologies (MBR + UV), which produce the higher quality recycled water, resulted in higher cost. The paper discusses the design and project execution approaches as how the more expensive advanced treatment processes were made cost competitive with the conventional treatment processes.

Improved external treatment of wastewater has become necessary for an increasing number of paper mills in view of stringent regulations governing the protection of receiving waters. Some of these advanced treatment processes have been shown to be useful after conventional primary treatment of wastewater with low concentrations of organics resulting from wood free paper production. For more contaminated wastewaters these state of the art techniques can also be used to supplement regular treatment like activated sludge processes. In these cases the advanced treatment processes are the final stage of a chain of mechanical, physico-chemical and biological treatment steps. The equipment and processes used for advanced treatment are sand filters, biofilters, low-capacity trickling filters, flocculation and precipitation with inorganic salts in combination with filtration or flotation. These procedures are designed mainly for a reduction in concentrations of suspended solids, COD, and phosphorus. Examples of the technical operation of these processes are presented. Compared to the results of standard treatment processes the results of the advanced treatment are a significant improvement As requirements for effluent quality will be maximized in industrialized countries in the near future - if this has not already been done - these processes will be needed, even if the costs are high.
