Rise of pH in oxidation ponds

efficiency of oxidation ponds in wastewater treatment

a research was conducted at kauma oxidation ponds, a sewage water treatment plant found in lilongwe, malawi with an aim of establishing the efficiency of these sewage treatment ponds in treating sewage wastewater. water samples from the effluent discharging points in the maturation ponds were collected and analysed in the labouratory for, bod, coliform bacteria, total nitrogen (tn), phosphorous...

Avian Botulism Epizootiology on Sewage Oxidation Ponds in Utah1

In the microenvironment concept of avian botulism epizootiology, it is hypothesized that invertebrate carcasses may serve both as a substrate for toxin production by Clostridium botulinum type C and as a vehicle for toxin transmission to water birds. We field-tested that hypothesis by attempting to induce botulism in wing-clipped mallard ducks (Anas platyrhynchos) on sewage oxidation ponds in U...

extraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds

سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...

Evidence for growth of enterococci in municipal oxidation ponds, obtained using antibiotic resistance analysis.

The Christchurch wastewater treatment plant uses a series of six oxidation ponds to reduce the bacterial load of treated effluent before it is discharged into the local estuary. To ensure that this discharge does not adversely affect water quality in the receiving environment, local regulations specify maximum levels in the discharge for a number of parameters, including enterococci. Between 20...
