Abstrak Kota Jakarta merupakan kota metropolitan yang tidak lepas dari permasalahan lingkungan seperti adanya timbulan air limbah domestik. Air domestik di salah satunya diolah dengan waste stabilization pond (WSP) dan sistem terpusat. Peningkatan jumlah pelayanan berubahnya karakteristik dapat mempengaruhi kinerja WSP. Tujuan studi ini adalah untuk mengevaluasi pengolahan WSP Jakarta. Adapun p...

The removal mechanisms and extent of degradation 28 chemicals (triclosan, fifteen polycyclic aromatic hydrocarbons, four estrogens, eight polybrominated diphenyl ether congeners) in different biological treatment systems [activated sludge, up-flow anaerobic sludge blanket reactor (UASB) waste stabilization pond (WSP)] was investigated to provide insights into the limits engineered systems. This...

The microalgal strain Chlorella sorokiniana isolated from a waste stabilization pond was used for tertiary treatment of municipal wastewater. Three light:dark (L:D) regimes 12:12, 16:8, and 24:0 were treating wastewater in microalga (A), + sludge (A S), (S) reactors. removal nutrients (N P) found to be the highest microalga-based reactor, with more than 80% biochemical oxygen demand (BOD) 1.2–5...

Waste stabilization ponds (WSPs) rely upon natural biochemical reactions for treatment and are used widely across the world. However, WSPs often fail to meet performance expectations due insufficient hydraulic performance. Installation of baffles can improve by increasing mean residence time, reducing dead zones, short circuiting, thus improving pond Theoretically, with ability sustain attached...

This study aims to determine the process waste management and test content wastewater in Regional Company Medan City. research was conducted from August September 2021. a descriptive quantitative laboratory tests were carried out. The population this 30 employees or workers at City slaughterhouse entire sampled because number relatively small. ...

<p>Soft clay soils generally have unfavorable characteristics or properties, when used as a basis for construction. The of soft soil are having high compressibility, low carrying capacity, permeability value, being cohesive and level activity. One form effort to improve the soil's bad properties is carry out stabilization. Stabilization an activity mixing with certain materials, expected ...
