Direct and indirect impacts of the projectDirect and indirect impacts of the project• Pollution of the environment originating from the use of
synthetic polymers can be reduced.• Due to the replacement of the synthetic flocculants used in
drinking water treatment the consumers can get healthier drinking water.
• The slow release encapsulating agents directly protect the health of workers who use the active agent, but indirectly also that of consumers who may meet the active agents in small concentrations.
• The scale inhibitors decrease the energy consumption due to the better heat transfer.
• The ion-exchangers and carriers also decrease the harmful effect of synthetic products of similar purpose on the environment.
• The Nitrokemia 2000 Co. locating in the near of Lake Balaton wishes to introduce up-to-date low-waste technologies for the production of its products planned.
