The quality of environment especially the water bodies need to be improved on the pollution load of the household wastewater, which in general still does not have a liquid waste treatment plant. Electrocoagulation used in this research because of the simple and efficient method. The aim of study to know the ability of electrocoagulation method for reducing the concentration of COD and TSS in the wastewater from household textile industry.  The sample was taken from the residual wastewater of textile dye (sarung) with a liquid waste requirement of 36 liters. The data for the analysis is the initial and final parameters data were COD and TSS. The electrodes were used aluminum (Al) as an anode and iron (Fe) as a cathode. The research variations were used the number of electrodes and the voltage. The results showed that the treatment of 4 electrodes with 12volt voltage could reduce the COD concentration up to 76% and TSS up to 85% in household wastewater of household textile industry. Keywords: COD, electrocoagulation, liquid waste, TSS

Abstract Background:The study conducted a comprehensive assessment of the quality of selected groundwater sources around the liquid waste treatment plant of Ahmadu University Teaching Hospital Shika, Nigeria. Water samples were collected from four (4) hand-dug wells following standard procedures, ten (10) physicochemical parameters and seven (7) heavy metals were analyzed.Results: All the physicochemical parameters studied were within the WHO specified limits except for DO which was less and turbidity which was higher. Heavy metals were found in the all the groundwater sources that were studied. However, the concentration of some heavy metals exceeded the specified limits recommended by the World Health Organization (WHO). The heavy metal presence in the groundwater sources may be connected to human activities such as waste disposal containing these metals around the groundwater sources and liquid waste from the hospital which can may have seeped into the wells.Conclusion: By implication, this study shows that the hand-dug wells were not safe for drinking. It is recommended that wells be sited away from dumpsites and waste treatment plants and effluents from waste treatment plants should also be properly treated before their subsequent discharge into the environment. This study has generated a baseline data that will be useful in monitoring heavy metal pollution.

Animal Sluaghterhouse (RPH) liquid waste contains organic matter, suspended solids, and colloid materials such as fat, protein, and cellulose with high concentrations that fall into the category of complex wastewater. RPH X is a RPH that uses Water Waste Treatment Plant (WWTP) in treating wastewater, although it has been equipped with WWTP there are still some problems in RPH X. The purpose of this research is to describe wastewater treatment and content of BOD, COD, TSS, NH3-N, pH and fatty oil at waste water in inlet and outlet of IPAL RPH X, Jember District. This research is a descriptive research. Technique of data collecting done by observation, interview, and laboratory test. The average of wastewater content test result in RPH X Jember Regency at inlet and outlet of IPAL is at safe limit of quality standard according to East Java Governor Regulation Number 72 Year 2013 except COD parameter at inlet that is equal to 277,6 mg / L. The average percentage of content in liquid waste in RPH X decreases from inlet to WWTP outlet except the pH parameter.

On 16 October 1996, a malfunction at the Swan Hills Special Waste Treatment Center (SHSWTC) in Alberta, Canada, released an undetermined quantity of persistent organic pollutants (POPs) into the atmosphere, including polychlorinated biphenyls, dioxins, and furans. The circumstances of exposure are detailed in Part 1, Background and Policy Issues. An ecologically based, staged health risk assessment was conducted in two parts with two levels of government as sponsors. The first, called the Swan Hills Study, is described in Part 2. A subsequent evaluation, described here in Part 3, was undertaken by Health Canada and focused exclusively on Aboriginal residents in three communities living near the lake, downwind, and downstream of the SHSWTC of the area. It was designed to isolate effects on members living a more traditional Aboriginal lifestyle. Aboriginal communities place great cultural emphasis on access to traditional lands and derive both cultural and health benefits from “country foods” such as venison (deer meat) and local fish. The suspicion of contamination of traditional lands and the food supply made risk management exceptionally difficult in this situation. The conclusion of both the Swan Hills and Lesser Slave Lake studies was that although POPs had entered the ecosystem, no effect could be demonstrated on human exposure or health outcome attributable to the incident. However, the value of this case study is in the detail of the process, not the ultimate dimensions of risk. The findings of the Lesser Slave Lake Study have not been published previously and are incomplete.

The Impact

The effect of discharging specific oil degrading bacteria from a chemostat to a refinery activated sludge process was determined biokinetically. Plant data for the kinetic evaluation of the waste treatment plant was collected before and during treatment. During treatment, the 500 gallon chemostatic growth chamber was operated on an eight hour hydraulic retention time, at a neutral pH, and was fed a mixture of refinery wastewater and simple sugars. The biokinetic constants k (days−1), Ks (mg/L), and K (L/mg-day) were determined before and after treatment by Monod and Lineweaver-Burk plots. Solids discharged and effluent organic concentrations were also evaluated against the mean cell retention time (MCRT). The maximum utilization rate, k, was found to increase from 0.47 to 0.95 days−1 during the operation of the chemostat. Subsequently, Ks increased from 141 to 556 mg/L. Effluent solids were shown to increase slightly with treatment. However, this was acceptable due to the polishing pond and the benefit of increased ability to accept shock loads of oily wastewater. The reason for the increased suspended solids in the effluent was most likely due to the continual addition of bacteria in exponential growth that were capable of responding to excess substrate. The effect of the chemostatic addition of specific microbial inocula to the refinery waste treatment plant has been to improve the overall organic removal capacity along with subsequent gains in plant stability.

As a rule, hazardous waste needs a pre-treatment, either a thermal or a chemical-physical one, before it can be disposed of at a landfill. The concentration of different kinds of treatment facilities at a Centralized Hazardous Waste Treatment Plant is advantageous. The facility of the ZVSMM at Schwabach is presented as an outstanding example of this kind of Treatment Centre. The infrastructure, the chemical-physical plant with separate lines for the treatment of organic and inorganic waste and the hazardous waste incinerator are described. Their functions are discussed in detail. Emphasis is laid on handling the residues produced by the different treatment processes and the final disposal.
