Biological treatment
Wastewater TreatmentEffluents from certain processes are not suitable for recycling to farmland by land spreading. Effluents resulting from chemical modification of starch may require a treatment before discharge. The traditional methods used for household sewage does not work for that simple reason that effluents from a starch derivative plant are not a steady and proper balanced diet for microbes.

We studied the behavior of effluents from chemical derivatisation in a one PE (Person Equivalent) bench scale equipment. After sampling data from continuous operation under various conditions and during prolonged tests we solved the problems and determined the parameters for successful operation of an artificial aerated sewage plant able to handle even difficult effluents.

Constructed wetlands is an efficient, reliable and energy saving alternative of particular advantage in the Tropics.
