AI Article Synopsis
- Coagulation and flocculation with bittern coagulant effectively treat batik industrial wastewater by removing heavy metals like lead (Pb) and reducing high turbidity levels.
- Bittern, derived from salt production and rich in magnesium, chloride, and sulfate, aids in precipitating contaminants when used in varying doses (5%, 15%, 25%, 35%) and stirring speeds (55 rpm, 90 rpm, 125 rpm).
- The study found that the best removal rates were 99.3% for Pb at a 35% coagulant dose and 55 rpm, and 97% for turbidity at a 15% coagulant dose and 125 rpm, with an optimal scenario
Article Abstract
Coagulation and flocculation using bittern coagulant are effective methods for processing batik industrial wastewater containing heavy metals and high turbidity. Bittern as residual seawater product from salt production can be used as a natural coagulant as it contains magnesium (Mg), chloride (Cl), and sulfate ions (SO ) which can react with Pb and turbidity to produce precipitation. This study focused on Pb and turbidity removal from batik wastewater by introducing different variations of coagulant doses and variations in fast-stirring speed. Bittern coagulant dosage (v/v) of 5%, 15%, 25%, and 35% were used while fast-stirring speed were 55 rpm, 90 rpm, and 125 rpm. Results of this experiment showed that variations of coagulants and stirring speed to give Pb maximum removal of 99.3% happened when coagulant dose and stirring speed at 35% and 55 rpm, while maximum turbidity removal at 97% happened when coagulant dose and stirring speed was 15 % and 125 rpm, respectively. Optimum dose using Response Surface Methodology (RSM) was at coagulant dose of 25% with 55 rpm, of which Pb and turbidity removal were 99% and 93%, respectively.

Bittern contains a high ionic strength that can be used as an alternative coagulant in wastewater treatment. The magnesium content in the bittern could promote the removal of suspended particles and nutrients as settleable precipitates. This would create a more compact and manageable sludge.

Coagulation of highly turbid suspensions using magnesium hydroxide: effects of slow mixing conditions.

Laboratory experiments were carried out to study the effects of slow mixing conditions on magnesium hydroxide floc size and strength and to determine the turbidity and total suspended solid (TSS) removal efficiencies during coagulation of highly turbid suspensions. A highly turbid kaolin clay suspension (1,213 ± 36 nephelometric turbidity units (NTU)) was alkalized to pH 10.5 using a 5 M NaOH solution; liquid bittern (LB) equivalent to 536 mg/L of Mg(2+) was added as a coagulant, and the suspension was then subjected to previously optimized fast mixing conditions of 100 rpm and 60 s.

Seawater bittern (nigari) is a concentrated solution remaining after the crystallization process of salt that has been used as a coagulant for tofu. Recently, various nigari products are distributed in the East Asia. To clarify the properties of nigari products, major mineral composition of six nigari products was determined.
