Soil Layering

Multi-Soil-Layering (MSL) method was applied to make appropriate, but high performance and N & P-removable, on-site domestic waste water treatment system. The MSL soil unit is composed from soil layer mixed with 10∼25% of metal iron and pelletized jute. The MSL units were piled in a brick pattern at 5cm vertical and 10cm horizontal distance, which were surrounded by layers of Zeolite. Air can be supplied through porous pipes installed at adequate depths of the MSL system. The systems were tested using model houses. The waste waters, which were pretreated by septic tank to the level of SS 29-75, BOD 42-116, COD 32-56, T-N 29-86, and T-P 6-11 mg−l−1 respectively, could be treated at the rate of 100-850 1·m−2·d−1 without significant clogging. The mean concentrations of treated waters were SS 15, BOD 8.7, COD 11, T-N 6.8, and T-P 0.86 mg·1−1 respectively. Zeolite layers and brick pattern prevent clogging. Metal iron and jute pellets were effective to remove Phosphate and Nitrate. Intensive aeration assists decomposition of BOD, COD, and SS as well as nitrification, but decreases denitrif ication and phosphate fixation. The degree of purification could be controlled by setting adequate aeration.

The motive of this paper to prepare some systematic low-priced and sustainable domestic waste water treatment system for household. To acquire this objective we collected samples from the household kitchen sink, basin, laundry etc. From the conclusion we learned that the tested parameters like BOD, COD, TDS, etc. displayed high removal of physical and chemical impurities. The treated water can be used for purposes such as irrigation, car washing, Flushing, etc.

Water Treatment System

Due to the increase of industrial activities both at local and national level, the quality of water in Indonesia is significantly degraded by time. Heavy metal wastes from industrial activities have become serious contaminants in the water. The contamination dangers human’s health since most people living near the river-bank still use the water to fulfill their daily needs. In this paper, we present the fabrication of Hydroxyapatite (HA) disc as a filtration medium in waste water treatment system. HA is one of biomaterial which can be derived from animal’s bone and is capable to absorb dangerous heavy-metal contaminants such as lead (Pb) in the water. Our produced HA was made by extracting cortical bovine bones into cortical bone HA powder. The cortical bovine bones were processed using physical method by heating the bones at 900oC to gained powder then followed by forming green bodies and sintering at 1000oC and 1400oC. Those powders were then pressed into a disc form and will be used as filtration media in HA modular purifier. SEM/EDX results show the disk surface has interconnected micropores and Ca/P ratio value on sintered HA disc at 1000oC and 1400oC are 2.20 and 1.85, respectively.
