This paper presents the methodology used for the rehabilitation of the pretreatment stage in a water treatment plant for a village located in Bolivia which has 3500 inhabitants. The treatment plant was initially composed by horizontal-flow roughing filters and slow sand filters, but due to the high contents of colloidal turbidity of the providing source, it did not work properly. A plan of rehabilitation was made which comprised laboratory tests, pilot tests and proposal of modifications based on the results of previous stages. The laboratory tests were made in order to find the optimum conditions to coagulate the raw water. It was found that horizontal-flow roughing filters must be turned into up-flow roughing filters, so a pilot plant was built and was operated for three months in order to find suitable design parameters. The results obtained obtained during the operation of the pilot plant and the proposal of modifications are presented. The results of operation of the final plant, which are also reported, demonstrated the advantages of the up-flow roughing filtration as a pretreatment stage when it is necessary to add chemical products in small treatment plants.

The Vaalkop plant, owned and operated by Magalies Water, provides a valuable South African case study of sludge and washwater management at a large water treatment plant. Starting out as a small plant of 18 Ml/day about thirty years ago, it has steadily grown to a plant with treatment capacity of 210 Ml/day; fairly large by South African standards. During the preceding years, it has not only been subject to a vastly larger scale of operation, but it also had to adapt to a tremendous increase in the cost of raw water, an increased environmental awareness amongst water treatment professionals and general public alike, and a much more sophisticated and complicated legislative framework. It is the objective of this paper to track the sludge and washwater management practices adopted over the years at Vaalkop, and to present the current strategies adopted for the medium to long term. The paper will summarize the previous methods of sludge and washwater disposal, with reasons why they were adopted. The multitude of technical analyses and alternatives that were performed over the years will be summarized, and may provide valuable pointers for other applications in South Africa. The current system, which has just been commissioned, will be presented; its technical design parameters, the anticipated mode of operation, its costs and how the current environmental and legislative requirements are being met.

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.

Clean Water

Water is one of the important components of human life or other living things. With the increasing number of residents, the need for clean water has also increased. However, this increase in demand is not offset by the availability of clean water due to the lower quality of water produced by the water treatment plant. Therefore, it is necessary to do alternative water treatment so that clean water needs can be sufficient. One method of processing clean water that can be done is the Jar test method. This study aims to determine the effect of coagulant dose addition on water quality parameters including pH, turbidity, TDS and total hardness of the Manisrejo City Madiun well water sample after water treatment. The research method is carried out through three stages, namely the preparation stage, the instrument analysis stage and the experimental stage. Where the type of coagulant used is Poly Aluminum Chloride (PAC). From the research that has been done, the optimum PAC coagulant dose is 43 mg / l. The conclusion obtained in this study is that the greater the coagulant dose added to the water sample, the smaller the pH value, the value of turbidity, the TDS value and the total hardness of the water sample.

The reuse of wastewater by the pulp and paper industry reduces environmental impacts by contributing to raw water conservation, thereby making a greater volume of fresh water available for nobler purposes, and reducing wastewater treatment. This study evaluated a proposed system of water reuse at a Kraft pulp and paper plant in Brazil, based on a survey of water quality required by its consumption points, supplied by its water treatment plant. Results after ultrafiltration included: turbidity of 0,3 NTU and pH 7,5, average values of BOD 66,4 mg/L, COD 9,6 mg/L and the colour of 280,5 ppm Pt were measured after ultrafiltration. The ultrafiltered wastewater was considered available for reuse, and its quality was compared with that of the water supplied by the water treatment plant, which provided for the classification of potential reuse points. Water colour was identified as the limiting factor for reuse; thus the reuse points were two Kraft paper machines, and the water flow to the liquid ring formations that generate the vacuums inside nineteen pumps for these two machines. The advantages of this proposal for water reuse include: ultrafiltered water quality sufficient for the vacuum pumps, the small distance between the point of reused water generation and the paper machines section, and the reused water has no contact with the final product. The calculated cost and return time for the water reuse system was US$ 607.020,00 in 15 years.

Abstract There are presented results of technological experiments carried out in Water Treatment Plant Kúty. The goal of this study was to compare modified zeolite known as clinoptilolite (rich deposits of clinoptilolite were found in the region of East Slovakia in the 1980s) with the imported modified zeolite from deposit situated in Hungary. Klinopur-Mn and Klinomangan were used for removal of iron and manganese from ground water to meet the requirements of the Regulation of the Government of the Slovak Republic No. 496/2010 on Drinking Water. The materials observed exhibit different efficiencies of manganese removal from water, since the quality of the treated water play a major role (oxygen content and pH value). In the case of the removal of the iron from the water, the quality of the raw water is not a limiting factor; both materials removed Fe from the water to below the limit value (0.20 mg.l-1).

Water Treatment Plant called IPA 1 located on Jl. Penjernihan II No.1 Pejompongan is one of the water installations owned by a water treatment company in DKI Jakarta that operates 24 hours non-stop to produce clean water with a capacity of 2500 liters per second (2500 lps). In a Water Treatment Installation (IPA) there is a process of processing and distributing water, to distribute water needs needed auxiliary equipment that is able to supply clean water as needed. In water supply applications at water treatment plants (IPA), the need for clean water, especially in the capital city of DKI Jakarta, is increasingly increasing, making the pump's performance even greater in its distribution so that it often ignores the amount of energy used in producing and distributing clean water. Testing a distribution pump is needed to determine the working characteristics of a pump. One of the variables tested to determine the pump's working characteristics in terms of electricity is to test the relationship between the motor rotation speed used (RPM) and the flow rate of water generated from the pump (liters / second). It can be seen that if the electric motor used to rotate the pump works in a low rotation, then the electric power used will be low and vice versa. One obstacle that may be faced when we are going to do a test to find out the motor rotation characteristics with the flow rate of water, especially in a water treatment plant in Jakarta is that the distribution of water to the public should not be interrupted when we do the testing, so the data obtained will be difficult to obtain completely, especially when the motor rotates at low speed. One approach that can be taken to look for values that are not measurable is to use polynomial regression. The purpose of this study is to look for variables that cannot be measured at the time of the test, especially the water speed rate variable at each motor rotation change which is regulated by Variable Speed Drive (VSD) on motor pumps number two, three, and four using formula obtained from the coefficients of the polynomial regression method. One formula produced by this polynomial regression is Q = 0.0005 N2 - 0.2231 N - 14.101, with an R2 value of 99.79%, where Q is the water flow rate (liters / second) and N is the motor rotation speed (RPM) ).ABSTRAKInstalasi Pengolahan Air IPA 1 yang berlokasi di Jl. Penjernihan II No.1 Pejompongan merupakan salah satu instalasi air yang dimiliki sebuah perusahaan pengolahan air di DKI Jakarta yang beroperasi selama 24 jam non stop untuk menghasilkan air bersih dengan kapasitas 2500 liter per detik (2500 lps). Pada suatu Instalasi Pengolahan Air ( IPA ) terdapat proses pengolahan dan pendistribusian air, untuk mendistribusikan kebutuhan air dibutuhkan peralatan bantu yang mampu menyuplai air bersih sesuai dengan yang dibutuhkan. Dalam aplikasi penyuplaian air pada instalasi pengolahan air (IPA), kebutuhan air bersih khususnya di daerah ibu kota DKI Jakarta semakin lama semakin meningkat membuat kinerja pompa semakin besar dalam pendistribusiannya sehingga sering mengabaikan besarnya energi yang di pakai dalam menghasilkan dan mendistribusikan air bersih.  Pengujian suatu pompa distribusi diperlukan untuk mengetahui karakteristik kerja dari suatu pompa tersebut. Salah satu variable yang diuji untuk mengetahui karakteristik kerja pompa tersebut dalam hal kelistrikannya adalah dengan menguji karakteristik hubungan kecepatan putaran motor yang digunakan ( RPM ) dengan laju aliran air yang dihasilkan dari pompa tersebut ( liter / detik ). Dapat diketahui bahwa apabila motor listrik yang dipakai untuk memutar pompa bekerja dalam putaran yang rendah, maka daya listrik yang dipakai pun akan rendah begitu pula sebaliknya. Salah satu kendala yang mungkin dihadapi pada saat kita akan melakukan pengujian untuk mengetahui karakteristik putaran motor dengan laju aliran air khususnya pada suatu instalasi pengolahan air di Jakarta adalah distribusi air kepada masyarakat tidak boleh terganggu pada saat kita melakukan pengujian, sehingga data yang diperoleh akan sulit didapatkan secara lengkap khususnya pada saat motor berputar pada putaran rendah. Salah satu pendekatan yang dapat dilakukan untuk mencari nilai-nilai yang tidak terukur  tersebut adalah dengan menggunakan regresi polynomial. Tujuan dari penelitian ini adalah mencari variable-variabel yang tidak dapat terukur pada saat dilakukannya pengujian, khususnya variabel laju kecepatan air pada setiap perubahan putaran motor yang diatur oleh Variable Speed Drive ( VSD ) pada motor-pompa nomor dua, tiga, dan empat dengan menggunakan rumus yang didapatkan dari koefisien-koefisien metode regresi polynomial. Salah satu rumus yang dihasilkan dengan regresi polynomial ini adalah Q = 0.0005 N2 – 0.2231 N – 14.101, dengan nilai R2 sebesar 99,79 %, dimana variable Q merupakan laju aliran air ( liter / detik ) dan variable N merupakan kecepatan putaran motor ( RPM ).
