Production of Existing System. Understand that we need to replace 4 units. How many unit can we shut down at a time do to the work. That changes our work procedure. In order for us to work without interruption, we need to know capacity and ability of each current unit. Especially the flow load.

Section 01 11 00 Summary of Work, suggests a viable construction sequence, and which treament units may be taken off line and shut down at any given time. Shut down will be one unit by one unit. Needs to be clarified by Waste Water Treatment Plant Manager ( Officially).

During contractor's development of Construction Schedule, WWTP Manager will need to approve construction sequence schedule.

Verification from WWTP Manager will come during proposal/construction schedule review.

Japanese Waste Water Treatment Plant Law. Japanese Waste Water Treatment System Law. We believe that this will not match the Japanese law once we upgrade the system as described. Should we not to follow the Japanese Law? ①There is no Primary Conditioning Tank ②There is no Third Chemical Sedimentation Process * We need the third process if we need to do the nitrogen removal.

The proposed treatment system will meet JEGS permit requirements.

Microscreens are designed to replace the primary clarifier. Nitrogen removal is accomplished with the use of a pre-denitrification single sludge nitrification/denitrification system, incorporating Anoxic Zones and an internal recyle system, reducing the reliance on chemicals and eliminating the need for separate nitrification/denitrification stages.
