Abstract:
Dairy industry is one of the major polluting industries in Palestine and elsewhere. Locally, dairy
wastewater is discharged into sewer system or open spaces without any kind of treatment
causing high organic loads and septic degradation.
The wastewater in dairy farms is an important problem in Palestine, where most of the
wastewater is dumped into unprepared pits or in open valleys, which causes many environmental
problems, for example, bad smells, harmful insects spread, groundwater pollution, and soil
pollution, so This water must be used and treated to make it usable again, especially in the
presence of the Israeli occupation.
The project aims to design and build an integrated system for treating wastewater in dairy farms
using algae. Besides that produce distilled water and biomass. Samples were taken to conduct an
exhaustive compilation of dairy wastewater characterization and a comparative study between
the different features of dairy wastewater, COD, pH, TDS, NO3.
Distilled water has been produced around 500ml daily, piece of kink at 20 X 20 cm dimensions
was take to check the volume of biomass growth because the results take days as like the features
of dairy wastewater .
The sample's measurement was taken four times in different days, at around 5:00 PM. Four tests
were taken for each sample TDS, NO3, pH, the results as shown in the figures.
The pH and NO3 readings shows positive changes during days, that's where the ratio of pH and
NO3 decreased, this indicates the ability of algae to treat wastewater.
