Climate change

In the present work meteorological data, concerning temperature and precipitation in a mountainous Bulgarian fir (Abies borisii-regis Mattf.) forest, was analyzed in order to find trends for the period 1973-2019. The results showed that temperature values on annual and seasonal base, especially in...

Water and wastewater treatment and reuse

A dynamic mathematical model, based on the biochemical kinetic processes dominated in shallow free water systems was developed following the Activated Sludge Model (ASM) methodology. The model predicts plant mass and water uptake rate, BOD 5 and total nitrogen (TN) removal on a year round basis...

Water and wastewater treatment and reuse

Denitrifying polyphosphate accumulating organisms (DNPAOs) are very promising for simultaneous nitrogen and phosphorus removal. While during denitrification, emission of a greenhouse gas, nitrous oxide (N 2O), may occur. In this study, DNPAOs were enriched in a lab-scale reactor, and N 2O emission...

Removal of ammonia by clinoptilolite

by

Zabochnicka-Swiatek M. and Malinska K.

Issue 3

General

The important advantage of zeolite applied to water treatment is its high porosity when comparing to other minerals. The porosity results in good hydrodynamic properties (the increase in the pressure loss on the zeolite filters is 1.5-2.0 times smaller than in the case of sand filters) and...

Denitrification as a component of Nitrogen Budget in a Tropical Paddy Field

by

Pathak B.K., Iida T. and Kazama F.

Issue 2

General

The direct assessment of denitrification suffers from a number of problems. A mass balance model is simple and widely accepted to calculate nitrogen (N) loss as a denitrification component. The objective of study was to estimate the potential N loss a denitrification from a tropical paddy in the...
