Clarification plant, Põlgaste, Estonia

The Project:


Renovation of a clarification plant


Companies involved:

OÜ Impel Ltd (Tsurumi Partner)


The Problem:


Replacement of the clarification technology, Installation of new items of equipment.


The Solution:


Preliminary clarification:

Installation of a screen of the Tsurumi type KS- 200z-2.5, with the aid of which solids are removed from the waste water.


Activated sludge aeration:

Installation of three compressors of the Tsurumi type RSR-80, each rated at 5.5kW, 1750 rev/min. Two compressors are in permanent operation, with another in standby mode. The compressors stand on a vibration damping base made of rubber, in order to keep noise levels low.


Surface suction removal:

A floating surface suction unit of the Tsurumi type 4-FSP removes foam and floating dirt from the water surface by suction.


Pumps:

Five pumps of the 40UA2.25 type are in operation at different points in the purification process.

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
