WASTEWATER TREATMENT EFFICIENCY CASE OF OXYLAG WASTEWATER TREATMENT PLANT, MHAYA (MOROCCO)

The wastewater from the urban commune of Mhaya (Morocco) was rejected directly into Ben Kazza river without treatment. This situation caused a widespread, massive, varied and insidious pollution of the environment. A wastewater treatment plant (WWTP) has been constructed in 2010 in order to preserve the nature surrounding the center. Called Oxylag, the plant has a nominal capacity of 6000 Equivalent Inhabitants. It is based on intensive treatment and it is considered as pilot and unique in Morocco. The treatment is consisting on three basins ventilated by insufflation of artificial air and a basin of finishing. The present study aim is the assessment of the purification performance of this plant during 2012, through the analysis of the pollution parameters (COD, BOD5 and TSS), which is the subject of the Moroccan standards on the quality of domestic wastewater defined by the decree Number 1607-06 of 25 July 2006. The results show a high purification performance in terms of carbon pollution removal (93% for BOD5, 79% for COD and 64% for TSS).

Household Wastewater

Abstract The study presents the legal requirements concerning the quality of wastewater discharged to waterbodies and to soil after treatment in household wastewater treatment plants located in agglomerations or outside them. The procedure of stopping the operation of a household treatment plant that doesn’t meet the statutory wastewater treatment efficiency was presented. The decision ordering to stop the use of a household wastewater treatment plant has to be preceded by a decision ordering to take measures to limit its adverse impact on the environment. The clarification procedure has to determine the adverse impact on the environment in a doubtless manner and it has to be reflected in the documentation. The assessment of adverse impact should take into account the binding standards of use of the environment. Stopping the operation of a household wastewater treatment plant may result in issuing a decision ordering the user to connect to the sanitary sewage system.

Pondok pesantren menyediakan asrama sebagai tempat menghuni para siswa. Beberapa kegiatan di asrama ini menghasilkan limbah. Semakin banyak penghuni yang menempati asrama semakin banyak pula limbah yang dihasilkan, salah satunya adalah limbah cair hasil dari kegiatan MCK. Pondok pesantren Nurul Musthofamemiliki jumlah penghuni dengan kapasitas maksimal 475 orang, sehingga apabila penghuni tersebut memenuhi kapasitas terbanyak, maka limbah yang akan dihasilkan adalah 45,6 m3/hari. Pondok pesantren ini memiliki beberapa sarana sanitasi yang kurang layak, oleh sebab itu perlu adanya upaya perbaikan sanitasi yakni merencanakan instalasi pengolahan air limbah domestik.yakni Anaerobic Baffled Reactor (ABR). Kualitas air limbah domestik BOD, COD, TSS, pH yang digunakan sebagai perencaaan yaitu 167mg/l, 469mg/l, 209mg/l, 7. ABR yang akan direncanakan memiliki 5 kompartemen dengan total dimensinya panjang, lebar, dan kedalaman adalah 9,85 meter, 2.8 meter, dan 2.3 meter. Biaya yang dibutuhkan untuk pembangunan ABR ini adalah Rp.225.000.000,00, dengan waktu kegiatan pembangunan yang direncanakan adalah 5 bulan. Kata Kunci : Anaerobic Baffled Reactor, Air Limbah domestic, Asrama, Pondok Pesantren. The Boarding school provides the dormitory as a living place for the students. Some of the activities in the dorm produce the wast. The more people who live in the dorm, the more waste that will beproduce, whice one is the wastewater from Bathing, Washing, and to defecate. Nurul Musthofa Boarding school has the occupants by maximal capacity of 475 people, if the occupants fill the most excessily capacity, the the wastewater that will be produced is 45.6 m3/day. This Boarding school has some inapproviate sanitation facilities, therefore it needs an improvement of the sanitation, that is to design the Wastewater Treatment Plant Anaerobic Baffled Reactor (ABR). The quality of domestic wastewater BOD, COD, TSS, pH used as planning is 167mg/l, 469mg/l, 209mg/l, 7. ABR planned to have 5 compartementswith a total dimesion of length, width, and depth is 9,85 meter, 2.8 meter, dan 2.3 meter. The cost needed for the construction of this ABR is Rp.225.000.000,00 Keywords : Anaerobic Baffled Reactor, the boarding school, the dormitory, wastewater.

Plant Evaluation

The communal domestic wastewater treatment plant functions to collect and treat domestic wastewater at the source location according to the communal scale treatment capacity. The communal Wastewater Treatment Plant (WWTP) in RT (neighborhood association) 01 / RW (citizen association) 09 Sindangrasa was built in 2016 using the Anaerobic Baffled Reactor (ABR) system. This study aims to evaluate the Communal WWTP by analyzing the quality of wastewater compared to PerMenLH No. 68 of 2016, calculates the processing efficiency and analyzes the water quality of the community wells around the Communal WWTP compared to regulation of PerMenKes No.416/MENKES/PER/IX/1990. Data collection techniques using the Slovin technique in the pre-research stage, direct sampling on location and testing in an accredited laboratory. The results showed the quality of wastewater exceeds the quality standard for BOD, TSS and Total Coliform parameters, the quality of residents' well water exceeds the quality standard for parameters pH, Cr VI and Total Coliform. Communal WWTPs in RT 01/ RW 09 Sindangrasa have not been efficient in treating residents' domestic wastewater. The management of Communal WWTPs needs to be improved so that the effluent quality and processing efficiency values meet the specified regulatory standards.

Toxicity Effects

An unusually severe case of toxicity accompanied by activated sludge filamentous bulking was observed at the wastewater treatment plant Sao Paulo-Barueri. Treatment efficiency of the plant, operated without major problems for more than five years before, was significantly hindered for almost six months. Occurrence of toxic shocks was confirmed partly directly but mostly indirectly by inhibition of nitrification and biological phenomena related to toxicity. Several measures adopted, including the recycled activated sludge chlorination, are described in the paper.
