Within the holding of Bührmann-Tetterode NV, 7 Dutch paper and board mills are operating, all of them using mainly waste paper as raw material. While three of them completely closed their watercircuits, two other mills put into practice biological waste water treatment namely anaerobic and anaerobic/aerobic. Number 6 is realising an anaerobic plant this year and for number 7 research is still being carried out, dealing with several unfavourable aspects. In September 1981 research for anaerobic treatment (UASB reactors) was started. After good results had been achieved on laboratory scale (301), further investigations were started on semitechnical scale (50 m3). In both cases the anaerobic seed sludge granulated after a while and loadings up to 20 kg COD/m3.d could be handled. COD-removal was 70 per cent, even when the hydraulic retention time was only 2.5 hours. In April 1983 a 70 m3 practical scale UASB reactor was started up at the solid board mill of Ceres. In October 1983 a full scale plant was started up at Papierfabriek Roermond. This plant consists of a 1,000 m3 UASB reactor and a 70 m3 gasholder. It has been designed and constructed by Paques BV and is used for pretreatment of effluent, in order to reduce the loading of the activated sludge plant. Besides energy savings on the oxygen input, about 1 million m3/year of biogas is being generated and is used for steamproduction. Both plants are working satisfactorily. Investment costs appeared to be relatively low. At Ceres, pay-out time is 1.5 year, while at Papierfabriek Roermond waste water treatment is cheaper than before, although capacity is doubled.

This paper aims to contribute to the assesment of a (more) optimal design and operation of a high rate anaerobic waste water treatment process. The discussion will be made on basis of available information of modern anaerobic waste water treatment processes, such as the Anaerobic Filter Process and the Upflow Anaerobic Sludge Blanket process and of recently introduced Attached Film processes.

Community service activities is one of the obligations that must be implemented by lecturer at the university sabagai one aspect of Tri Dharma Perguruan Tinggi. The activity was carried out by a Team of Community Service entitled "The Application of Coconut Waste Processing Technology as Organic Fertilizer and Nata de Coco" is a devotion activity involving two partners, namely Bakti Karya Farmer Group and Mekar Jaya Farmer Group are two groups of farmers who are active in cultivation and coconut cultivation in Desa Asahan Mati, Tanjung Balai Sub-district of Asahan Regency. Problems faced is the low quantity and quality of coconut production caused by the limited information about the culture culture of coconut cultivation, especially aspects of pest control and fertilization. In addition, the presence of coconut straw waste in the form of midrib and leaves and coconut water that is very large to be a problem because it has the potential to cause environmental pollution and become a pest of nests. . In order to solve the problems of both partners, this activity will be conducted in the form of lectures, discussions, practices and introduction of coconut chopping machine in the form of leaf and stem to be used as raw material of organic fertilizer, hybrid coconut seeds and coconut waste water treatment equipment as nata de coco . After the implementation of the dedication activity to the partner community has been able to make organic fertilizer bokashi by utilizing the waste of coconut plants by digging the compost cutting machine that introduced, the practice of hybrid coconut cultivation, and waste water treatment of coconut to nata de coco. The results of these activities can increase hybrid coconut production while maintaining environmental sustainability,

The use of biological anaerobic treatment for sludge digestion in treatment plants has a Jong operational record. The result is a lower amount of stabilised sludge and a considerable energy output, as heat and possibly also electrical energy. In industrial waste water treatment, anaerobic processes have also been used quite a Jong period, especially in food and pulp and paper industries. The anaerobic treatment of organic waste from industries or municipal waste, is a more recent application. The paper presents a summary of used anaerobic technology, with a special case from the Kalmar waste water treatment plant, where the two existing sludge digesters are upgraded to termophilic anaerobic treatment, one unit t be used for sludge and the other, separately, for organic waste from food industry and manure from farms.

It is challenging work to develop a low-cost, efficient, and environmentally friendly Cr(VI) adsorbent for waste water treatment. In this paper, we used hemicelluloses from chemical fiber factory waste as the raw material, and prepared two kinds of carbon materials by the green hydrothermal method as adsorbent for Cr(VI). The results showed that hemicelluloses hydrothermally treated with citric acid (HTC) presented spherical shapes, and hemicelluloses hydrothermally treated with ammonia solution (HTC-NH2) provided spongy structures. The adsorption capacity of the samples can be obtained by the Langmuir model, and the adsorption kinetics could be described by the pseudo-second-order model at pH 1.0. The maximum adsorption capacity of HTC-NH2 in the Langmuir model is 74.60 mg/g, much higher than that of HTC (61.25 mg/g). The green hydrothermal treatment of biomass with ammonia solution will provide a simple and feasible way to prepare adsorbent for Cr(VI) in waste water treatment.

A new procedure for electroplating waste water treatment using a waste iron scrap by-product for nanoparticle ferriferous hydrosol (FFH) preparation is presented. FFH which contains Fe(II) and Fe(III) was employed for neutralization and heavy metal removal from electroplating wastewater as well as for decontamination of concomitant pollutants such as phosphates, organic compounds, residual oils, dyes and detergents. It is possible due to the simultaneous operation of several different mechanisms: sorption, coagulation, reduction, fertilization and etc. The method is suitable for the purposes of waste water treatment and disposal in compliance with environmental laws and is implemented in some East and West European countries. The results were proved in accredited laboratories in various countries. According to the composition of its water extractable fraction, remaining waste sludge could be safely deposited in urban waste repositories or used as a raw material for production of various technically useful products such as ceramics, pigment, etc. Treated water may be reused in technological processes.
