Abstract

A research aims to understand the effectiveness of the use of palm (Elaisguineensis) shell as biofilter media in the aerobic system to decrease the ammonialevel in the tempe industry liquid waste has been conducted in the Tuah Karya Village,Pekanbaru. Results shown that during the seeding period, the value of ammonia was23.37-39.12 mg/L in the inlet. During the research period, the ammonia value was19.78-27.63 mg/L and by using the palm shell, the value was 25.52-39.48 mg/L in theinlet and 18.85-30.64 mg/L in the outlet. Without using the palm shell, the ammoniavalue was around 33.12-41.35 mg/L in the inlet and 28.17-34.69 mg/L in the outlet.Based on the results obtained, it can be concluded that the used of palm shell iseffecient to decrease the ammonia level in the tempe industry liquid waste.

Abstract

This research was conducted in the laboratory of waste Processing Technology and the laboratory of Water Quality Management in the FAPERIKA – UNRI. The aim of this research is to identify the ability of chitosan in reducing the level of TSS in the wastewater of plywood industry. The method used in this research is  experimental study with completely randomized design, one factor, 4 level, 12 units of trial. Several concentration of chitosan such as 0 mg/L, 15 mg/L, 30 mg/L were applied on the wastewater and observed after 8 hours, 12 hours and 16 hours. The result shown that 12 hours after addition of 30 mg chitosan /L, the quality of the waste improved : TSS 182,3 – 56,7 mg/L, Phenol 2,4 - 0,5 mg/L, BOD5 132-93 mg/L, COD 279-217 mg/L and pH 6 - 9.
