Abstract

Peat water has potential as a source of raw water because of its considerable availability, but the characteristics of peat water have not standard of quality according to Permenkes No.416/MENKES/PER/IX/1990 and PP. 82 of 2001. One method of peat water treatment is coagulation flocculation that requires coagulant. Tamarind seed powder is one type of natural coagulant substitute chemical coagulant because it contains tannin, natural polymer such as starch, sap, and albuminoid that play a role in water purification. This research used coagulation and flocculation method with combination of stirring variation 100 rpm / 40 rpm; 125 rpm/45 rpm; 150 rpm/50 rpm and 10 minutes flocculation time; 20 minutes; 30 minutes using Tamarind seed powder with 200 mesh particle size and dose 2,5 gr/200 mL peat water to the decrease COD, dyestuff, organic matter, TSS, and pH. In this study also conducted pH conditioning at peat water pH and pH condition 7. The results showed that peat water treatment at fast rapping speed 125 rpm, slow stirring speed 45 rpm and slow stirring time 20 minutes at natural pH condition of peat water (4,69) using Tamarind seed powder have the best effect on water quality parameter and able to increase water pH. Decrease in COD by 75.90%; dye of 84.59%; organic matter 72,12%; and TSS of 81.70% and peak water pH to 6,8.

Abstract

Coagulation and flocculation process is used because of it’s ability to remove colloids and suspended particles that contained in laboratory wastewater. The wastewater of Fundamental Chemical Laboratory contained very high concentrations of TSS and TDS, therefore coagulation and flocculation process is needed. This research was conducted to determine the optimum coagulant dose of PAC (Polyaluminium Chloride) in remove TSS and TDS. The determine of optimum coagulant is done by varies doses of PAC within 400, 500, 600, and 700 mg/L. Jar test method resulting the optimum condition of coagulant PAC is in 600 mg/L. Based on the result, the final concentration of TSS and TDS have met the Type II waste water quality standards, but TDS concentrations are still above the Type I waste water quality standards.Keywords: Laboratory Wastewater, Coagulation, Flocculation, Poly AluminiumChloride (PAC), TSS, TDS.

Abstract

Peat water is a blackish brown surface water And contains colors and turbidity that require effective treatment And efficient to be suitable for use by the society. Various types of coagulant continue to be developed one of which is the coagulant of clay with the addition of alum. The purpose of adding coagulant is to destabilize the colloids so that contacs and clumping of particles that will form a deposited floc. This study aims to calculate the efficiency of color and turbidity in peat water and compare the color quality, and turbidity with the standard of clean water quality standard (Permenkes 907 year 2002). The fixed variable used in this study was stirring speed of 100 rpm at contact time of 1 minute and 20 rpm at contact time 15 minutes. The free variable used consisted of 1 grams alum coagulant mass: 0.2 grams of clay soil, 1 grams alum coagulant mass : 0.4 grams of clay soil, 1 grams alum coagulant mass : 0.6 grams of clay soil, 1 grams alum coagulant mass : 0.8 grams of clay soil, 1.0 grams alum coagulant mass : l grams of clay soil .

Abstract

Treatment of palm oil mill effluent still leaves a lot of challenges in terms of both technology and quality standards. Therefore, we need a wastewater treatment system that can provide optimal results in processing and controlling the environmental impact of waste that can be reduced. Phytoremediation is a method of alternative technologies need to be developed to address these challenges. This study aims to determined the pollutant removal efficiency parameters BOD in the palm oil mill effluent, study the influence of variations in plant density, waste content variation, and variation of the residence time of the wastewater treatment efficiency of phytoremediation method. Compare the results of treatment of palm oil mill effluent by phytoremediation method using Typha latifolia with effluent standards for palm oil mill based on the Keputusan Menteri Lingkungan Hidup Nomor 51 Tahun 1995. This research used reactor phytoremediation the size of 50cm x 36cm x 31cm, thickness 10cm soil media, media thickness 5cm sand and gravel media 5cm thick with research variables include plant density variations Typha latifolia (0,5g/cm2; 0,75g/cm2; dan 1g/cm2), variations in the levels of palm oil effluent (20%; 60%; dan 100%), and variation of the residence time ( 5 days and 9 days ). The results showed that the highest efficiency is on density variations in plant 1 g/cm2 , 20% waste concentration, and residence time of 9 days with BOD 97,33 %.

Abstract

Palm Oil Mill Effluent treatment produces sludge as byproduct. Without being processed, the sludge will cause damage to environment and industry. The aim of this research is to convert the sludge, combined with boiler ash and palm oil fiber and litter of dry leaves into compost by using EM-4 as the activator. The instrument needed is a simple composter with height 40 cm and diameter 30 cm. The variations of the boiler ash dosage are 1 kg, 1,5 kg and 2 kg and the variations of composting time is 21 days in order to analyze the compost quality produced. The research showed that compost with 1 kg boiler ash dosage processed for 21 days resulted to a C/N ratio that meets SNI’s requirement 19-7030-2004 C/N ratio=11,72. The conversion of palm’s oil sludge into compost can be used as an alternative in utilization waste into valuable product.Keywords: boiler ash, EM-4 activator, compost, fiber, palm’s sludge
