Abstract

In drinking water treatment plants, there is a coagulation unit that requires coagulant substances. Coagulant dosage determination can be done using the jartest method. By carrying out a jar test, the correct dose will be known so that the coagulation process runs well, and the use of coagulants can be optimized. This research was carried out by analyzing jartest results from the company's internal laboratory for one week with two variations in jartest times in one day. The raw water used comes from shipping rivers with a company production capacity of 500 l/second. The dosage of Aluminum Sulphate coagulant used in the field is 165 mg/l, while the jastest results show that the optimum dosage is 140 mg/l. This research is expected to provide scientific information regarding determining coagulant dosage at IPAM PT Hanarida Tirta Birawa which makes it easier for installation operators.

Abstract

Shipyards are often criticised for the liquid waste they produce, which has the potential to contaminate marine waters. This research aims to analyse the effectiveness of chitosan from blood clam shells as an adsorbent to reduce the levels of lead and copper in shipyard liquid waste. The research technique uses a batch system. The materials used include both commercial and non-commercial blood clam shell adsorbents. The non-commercial blood clam waste was collected from a fish auction site in Kalanganyar village, Sidoarjo. The concentrations of lead and copper in the wastewater samples were 2.04 and 1.16 mg/L, respectively. Variations in the adsorption stirring speed (90, 100, 110 and 120 rpm) and the amount of commercial and non-commercial blood clam shell adsorbent added to the wastewater samples (0.5; 1; 1.5; and 2 grams) were tested. Measurements were then performed using atomic absorption spectroscopy (AAS). At final concentrations of 0.150 mg/L and 0.144 mg/L, the research results show that the commercial adsorbent with a mass of 2.0 grams and a stirring speed of 110 rpm was able to absorb Pb and Cu metals at 92.65% and 87.58% respectively, while the non-commercial adsorbent with a mass of 2.0 grams and a stirring speed of 110 rpm was able to absorb Pb and Cu metals at 91.81% and 82.31% respectively.
