Wastewater with suspended solids should be pretreated in a settling tank. A correctly designed settling tank should provide optimal treatment efficiency and sufficient storage capacity for suspended solids.
A settling tank can be a standalone device (Settling Tanks) or can be integrated with a coalescence separator where the settling tank is placed below the coalescence column – typically marked H (e.g. ESK-H, ESK-BH etc.). The purpose of such integrated system is to reduce the size of treatment installation, while providing high degree of treatment of petroleum derivatives and suspended solids. It is used mainly in highly urbanised areas.
Optionally, this device can be fitted with an alarm system (Monitoring System) or linked up to Bumerang, an intelligent rainwater management system.
The design of a settling tank depends of the location where it is supposed to work, the degree of wastewater pretreatment (rainwater or technological), flows and the estimated amount of suspended solids in inflowing wastewater (Settling Tanks).
The EST-H grease separators meet the requirements of the PN-EN 1825 standard. The EST-H separators are CE marked for use in the European Union.
