Abstract Quantity and quality of raw domestic wastewater are reviewed and discussed for packaged plants, known as johkasou, in Japan. A method for the estimation of johkasou capacity in terms of population equivalent, or PE, was introduced and discussed in this paper. It was found that the pollutant loads of domestic wastewater were respectively BOD 45 g, CODMn 23 g, SS 37 g, TN 9.3 g and TP 1.1 g per capita per day on average. It shows that the BOD load of wastewater from kitchens is higher than that of black water. The estimation of the johkasou capacity needed for buildings can be done using a series of formulas, which forms an important estimation method for the implementation of on-site wastewater treatment.

This paper aspires to examine the environmental effects of financial market development (FMD), foreign direct investment (FDI), and trade openness on the CO2 emissions per capita along with the environmental Kuznets curve (EKC) hypothesis in six East Asian countries from 1991–2014. For this purpose, spatial econometrics is applied to consider the spillover effects from neighboring countries. The results of the study corroborate the spillover effects from neighboring countries’ CO2 emissions per capita, FMD, FDI, and trade openness, and the EKC hypothesis is proven true in this region. Local FDI inflows, trade openness, and energy intensity are found to be responsible for local environmental degradation. Local FMD has an insignificant environmental effect, but neighboring countries’ FMD has contributed to the local CO2 emissions per capita. Further, positive (negative) environmental spillover effects are found from neighboring countries’ FDI (trade openness).

The various emissions to water, air and soil from the municipal wastewater treatment plant Avedore Wastewater Service Company are accounted for and quantified in terms of the environmental impacts to which they contribute: global warming, acidification, eutrophication, space demand for controlled deposition of residues, as well as persistent toxicity, human toxicity and eco-toxicity. The impacts are expressed on the same scale, namely as fraction of the total per capita loads in a national scenario 1990, also called the person equivalent or PE1990. This provides a compact and informative overview of the environmental impacts and allows for a holistic prioritisation in the operation and management of the plant. The accounting shows that the resulting emissions per person in the catchment area of the plant correspond to 0.5-5.0% of the average Danish PE1990 for the impacts in question.

Wastewater Treatment Systems

In developing countries with large Millennium Development Goals (MDGs) sanitation indicator, pollutant discharge reduction function of wastewater treatment systems should be considered. In this paper, pollutant generations per capita (PGCs) and pollutant discharges per capita (PDCs) are estimated as a base dataset for wastewater management in Thailand. PDCs of black water, i.e. toilet wastewater, are found to be much smaller than PGCs of black water. However, PDCs of gray water, i.e. municipal wastewater other than toilet wastewater are large. Gray water is often discharged without treatment and contributes much to ambient water deterioration. Moreover, possible 5-day biological oxygen demand (BOD5) discharge reductions with “soft interventions”, i.e. measurements in households to reduce wastewater pollutant discharge such as using a paper filter or a plastic net in kitchen sinks and so on, are estimated as 39, 21 and 34% for BOD5, total Kjeldahl nitrogen (TKN) and phosphate (PO4-P), respectively. For the estimation, environmental accounting housekeeping (EAH) books of domestic wastewater, spreadsheets with pollutant discharges by water usages and possible effects of “soft interventions” are applied. The framework of this study with “soft intervention” effects on pollutant discharge reductions should enhance wastewater management especially in the areas under development of wastewater treatment systems.

The Federal German Water Law of 1976 postulated for the first time that a license for the discharge of wastewater into public water courses might only be granted when the wastewater prior to the discharge is treated according to the actual standards. Also since 1976 it was decided that for the residual pollution of wastewater a pollution fee has to be paid. Assuming certain loads per capita one can calculate that presently three pollution units have to be paid per capita and year for untreated domestic wastewater. One pollution unit is assessed with 50 DM per year in 1991 but the price will be increased to 90 DM per year in future. Since the pollution units encompass COD, nitrogen, phosphorus, heavy metals and chlorinated carbon compounds the pollution unit is a very good tool to compare the effectiveness of treatment. For different drainage systems one can also calculate the residual pollution units per litre and second for low flow conditions.
