In May 2015 Buwatec executed a tank for sludge from a wastewater treatment plant.
In this installation, water is treated with NaOH and PAC which give rise to flocculation. Additionally polymer is added for a better settlement.
This treatment plant is equipped with a complete plastisol coated tank. An industrial tank liner of EPDM material has been selected due to composition of the sludge and effluent overflow water.
The storage capacity of this BUWAtank is 750 m3. It has been provided with a special staircase construction which contains even an inspection platform.
This buffer tank is also prepared for a full cover system in the future.
