Abstract

The Badaksinga Drinking Water Processing Installation is an installation owned by Perumda Tirtawening Drinking Water, Bandung City, has 2 of these installations, the first of which is a design from Degremont - France, built around 1954 with a capacity of 1000 liters/second. The second installation is an IWACO-Dutch design with a flow rate of 800 liters/second. The raw water for the two installations comes from the Cisangkuy River and the Cikapundung River. To purify the raw water, PAC (Poly Aluminum Chloride) is used as a coagulant which is a complex inorganic compound with a clear to yellowish color. The coagulant addition process must be carried out efficiently because this coagulation process is a chemical process that requires a large amount of money for the water treatment process apart from chlorination. Excessive addition of coagulant doses will cause the cost of using coagulant chemicals to swell so that it will have an impact on overall operational costs. The purpose of this study was to determine the effectiveness of using PAC in reducing turbidity, in the form of the optimum dose of coagulant, turbidity and pH. The method used is the Jar Test which is a tool to test the ability of coagulants to determine the optimum dose in a water treatment process. From the samples, the raw water turbidity varied from 17.1 to 281 NTU, fluctuating due to geographical location and environmental conditions around each and the degree of acidity or an average pH of 7.13. After the Jar Test was carried out, the optimum dose was produced at a coagulant concentration of 30 mg/l resulting in turbidity in the range of 1.1 to 5.0 NTU and an average turbidity reduction efficiency of 94.5%, the pH of raw water, after coagulation and flocculation with the Jar Test simulation tool, there was a decrease of 4.1% to an average of 6.99. This result is in accordance with Minister of Health Regulation No 492/MENKES/PER/10/2010 April 19 2020, namely turbidity of no more than 5 NTU and a pH of 6.5 – 8.5

聚合氯化铝混凝剂对IPAM性能的影响

Badaksinga饮用水处理装置是万隆市Perumda Tirtawening饮用水公司拥有的一个装置，有两个这样的装置，第一个是法国Degremont设计的，建于1954年左右，容量为1000升/秒。第二个装置是iwaco -荷兰设计的，流速为800升/秒。这两个设施的原水来自慈江和赤卡朋洞江。为了净化原水，使用PAC(聚氯化铝)作为混凝剂，PAC是一种复杂的无机化合物，颜色为透明到淡黄色。混凝剂添加过程必须高效进行，因为该混凝过程是除氯化外，水处理过程中需要大量资金的化学过程。过量添加混凝剂剂量会导致使用混凝剂化学品的成本膨胀，从而对总体运营成本产生影响。本研究的目的是通过混凝剂的最佳剂量、浊度和ph值来确定PAC在降低浊度方面的有效性。使用的方法是罐子试验，这是一种测试混凝剂在水处理过程中确定最佳剂量的能力的工具。从样本来看，原水的浊度在17.1 - 281 NTU之间，由于地理位置和周围的环境条件以及酸度或平均pH值7.13而波动。进行Jar Test后，最佳混凝剂浓度为30 mg/l，浊度范围为1.1 ~ 5.0 NTU，平均浊度降低率为94.5%，原水经Jar Test模拟工具混凝絮凝后，pH值降低4.1%，平均为6.99。该结果符合卫生部2020年4月19日第492/MENKES/PER/10/2010号条例，即浊度不超过5 NTU, pH值为6.5 - 8.5
