Solid/liquid separations are commonly the first step in any wastewater treatment. Such technologies are mature and new developments are rare. However, in the last decade some significant improvements in separation techniques for industrial wastewater pretreatment have been implemented. Advances in the technology include more efficient, faster centrifugal mixing of treatment chemicals and wastew...

Seiring berkembang nya teknologi kebutuhan masyarakat juga ikut berkembang, dengan diciptakannya berbagai kegiatan sepele yang biasanya dilakukan oleh sekarang sudah bisa digantikan otomasi sehingga manusia lebih fokus melakukan pekerjaan penting dan berarti secara otomatis meningkatkan produktivitas masyarakat. Begitu budidaya lobster air tawar CV. Ful Lobster Surabaya, sendiri memerlukan perh...

To statistically quantify ground and surface water interaction using temperature as a tracer its effect on chemical properties of rivers, total number 30 sample points were selected at regular intervals along the profile two rivers. Ten upper Ona River, ten Alaro remaining lower section river. Also, corresponding nearby groundwater samples obtained from parallel source, for each so to aid compa...

in recent years, the groundwater resources in guilan province have played an important role in irrigating paddy fields. the goal of this study was to evaluate temporal and spatial variations of groundwater quality in a 4-year period using ordinal kriging. water samples for this study were collected from 130 wells across guilan province, in september and march from 2003 to 2006.  maps of ec and ...

Sinking particles, once caught in sediment trap jars, release dissolved elements into the surrounding medium through leaching from their pore fluids, chemical dissolution and the activity of free exoenzymes. This results in an increase in dissolved elements in the trap jar supernatant. Elemental fluxes as traditionally measured by sediment traps underestimate total export when this particle-ass...

Our understanding of the cycling of fire-derived, i.e., pyrogenic organic matter (pyOM), as well as the goals of the community of researchers who study it, may be inhibited by the many terms and methods currently used in its quantification and characterization. Terms currently used for pyOM have evolved by convention, but are often poorly defined. Further, each of the different methods now used...

The increasing consumption of energy with the depletion of crude oil reserves urges the usage of alternative fuel. Since there is an existing demand for edible vegetable oils, waste vegetable oils and non-edible crude vegetable oils are preferred as potential low priced biodiesel sources. In this present work the utilization of a commonlyavailable bioenergy crop in the Western Ghats region,Crot...

In the wastewater treatment process, floatation unit have been developed to remove particles or flocs that tend be difficult settle, such as fat oil and grease (FOG) total suspended solids (TSS). Flotation is a operation can separate liquid phase solid from phase, this occur due presence of saturated air which mixed so it contains fine bubbles help separated. This research was conducted by trea...
