Treatment Technique

A cleaning site for road and rail car tankers emits a waste water stream of 200-250 m3/d. The waste water was originally treated in a physico-chemical waste water treatment plant. It was required to improve the effluent quality in order to meet the future discharge limits. As a possible treatment technique the sequencing batch reactor (SBR) technology, with an option for powdered activated carbon (PAC) dosing, was selected. Waste water originating from road and rail car cleaning installations is known to be potentially toxic/inhibitory. As a first step in the design procedure a pilot test was run for a period of 8 months. This pilot showed the SBR to be an appropriate technology for the treatment of the waste water. The PAC option was not feasible. Based on the pilot results a full scale installation, comprising a batch reactor with a diameter of 10.4 m and a maximum water depth of 17.3 m, was designed and successfully started up. This paper presents the highlights of the total project.

High Level

Generally, wastewater of nata de coco industry contains suspended solids and COD were high, ranging from 90,000 mg / l. The high level of of the wastewater pollutants, resulting in nata de coco industry can not be directly disposed of its wastewater into the environment agency. Appropriate technology required in order to process the waste water so that the treated water can meet the environmental quality standards that are allowed. Designing the waste water treatment plant that is suitable and efficient for treating industrial wastewater nata de coco is the activated sludge process. Wastewater treatment using activated sludge process of conventional (standard) generally consists of initial sedimentation, aeration and final sedimentation.Keywords : Activated Sludge, Design, IPAL

Sharon Process

A new biological process for ammonia removal from flows containing hundreds to thousands milligrams NH+4 per litre has been developed at the Delft University of Technology. The SHARON process operates at a high temperature (30–40 °C) and pH (7–8). The process is performed without sludge retention. This enables the prevention of nitrite oxidation, leading to lower operational costs. Denitrification is used to control the pH. A full scale plant was designed (1500 m3) based on kinetic and stoichiometric parameters determined at 1.5 1. scale and model predictions. Total costs are estimated at about $1.7 per kg removed NH4+-N. The first full scale SHARON plant will be operational at the Dokhaven waste water treatment plant in Rotterdam in the beginning of 1998. This contribution focuses on the principles of the process and evaluates conditions for which application seems feasible.

Recirculation Flow

An ASM2da model of the full-scale waste water plant of Bree (Belgium) has been made. It showed very good correlation with reference operational data. This basic model has been extended to include an accurate calculation of environmental footprint and operational costs (energy consumption, dosing of chemicals and sludge treatment). Two optimisation strategies were compared: lowest cost meeting the effluent consent versus lowest environmental footprint. Six optimisation scenarios have been studied, namely (i) implementation of an online control system based on ammonium and nitrate sensors, (ii) implementation of a control on MLSS concentration, (iii) evaluation of internal recirculation flow, (iv) oxygen set point, (v) installation of mixing in the aeration tank, and (vi) evaluation of nitrate setpoint for post denitrification. Both an environmental impact or Life Cycle Assessment (LCA) based approach for optimisation are able to significantly lower the cost and environmental footprint. However, the LCA approach has some advantages over cost minimisation of an existing full-scale plant. LCA tends to chose control settings that are more logic: it results in a safer operation of the plant with less risks regarding the consents. It results in a better effluent at a slightly increased cost.

Start Up

The sludge water obtained from the dewatering processes following anaerobic sludge digestion contains high levels of ammonia. This sludge water is generally returned to the beginning of the waste water treatment plant process, thereby significantly increasing the nitrogen load on the biological process. In this project, the start-up of a full-scale sequencing batch reactor (SBR) process to separately treat the aforementioned sludge water is studied. Two parallel SBRs were operated over 8 hour cycles. The duration of the start-up was approximately 100 days until a hydraulic load of 225 m3/d was reached for each SBR. This paper presents the results of the start-up, highlighting the change in nitrogen concentration with time and the effect of other parameters such as temperature and suspended solids in that period. Following the project period of operation, the ammonium concentration was reduced by more than 95% on average.

Paper Machine

The need for paper today continues to increase, economic growth also means increased forward to improve. The production of industrial paper in National and International market (export) so as to encourage paper mills continue to increase its production. Indonesian paper production in 2011 reached more than 11 million tons. All these activities will result in a positive or negative nature. One of the negative impact that a "focus" is the Pollution of Surface Water / Water River. Since 2005 has recorded more than 62 Watershed (DAS) in a critical condition. The paper industry needs clean water as a raw material of about 10-30 m³/ton paper, waste water thus generated is potentially polluting the river. Such a large volume of waste water and have different characteristics from other industries that require serious optimizing reduction strategy content of hazardous and toxic waste(B3).Factually the wastewater coming out of "paper machine" must be processed through the Waste Water Treatment Plant (WWTP) because as "output" it there are 2 (two) components: First ; Effluent discharge, must accept the Standards of Quality by the Government, as  appropriate: Kep-51/MENLH/10/1995, Date: October 23, 1995.Second: Sludge (B3), solid waste is processed through a form of WWTP sludge with fiber content, CaCO3 and other particles carried by the waste water, Standard of Water Quality Management and Water Pollution Control : PP. no. 82 / 2001. The buildup of sludge need to swatch innovation measures that can reduce pollution / minimize the risk of  the Watershed (DAS) Citarum.

Fluidized Bed Incineration

The first full-scale anaerobic waste water treatment plant in the Finnish wood processing industry has been completed at Anjala Paper Mill. This TAMAN process together with the extensive renewal of the water circulation systems as well as solids recovery have made it possible to meet the new environmental requirements coming into force in June 1987. The total BOD7 reduction due to this investment program is nearly 90 %. The waste water flow through the TAMAN process is 11000 m3/d. The specific water consumption of the debarking plant has been minimized and circulation water is clarified in a separate settler. TAMDEC gravity thickeners make solids retention more effective and the TASSTER screw press ensures that all the mill's sludge is dewatered before fluidized bed incineration.
