4 FAQs about 120kW Photovoltaic Unit for Wastewater Treatment Plant IP54 Outdoor Cabinet

Does a water treatment plant need a backup?

It's also a necessity. Water treatment must be able to function no matter what. So, if there's a power outage, a water treatment plant has to have a backup. Most treatment plants run on energy generated from fossil fuels or nuclear power, but some are using renewable energy, specifically solar energy.

How many m2 is a PV panel installation area?

The PV panel installation area was set such that the total annual PV power generation and the total annual electricity demand of the WWTP were approximately equal. These values were 6300 m2 under the base scenario, 5700 m 2 under the Save-E scenario, 5400 m 2 under the DR-W scenario, and 5600 m 2 under the DR-W+S scenario.

How many od tanks does the WWTP have?

The WWTP was severely damaged by the 2011 Tohoku Earthquake and was reconstructed. The plant possesses two OD tanks, each with a disposal capacity of 1303 m3 /d, but only one tank is in constant use in light of daily inflow (average 873 m 3/day in FY2018).

How many M2 does a wastewater treatment plant need?

The plots were constructed under the assumption that the total annual PV power generation and the total annual electricity demand of the wastewater treatment plant were approximately equal: 6300 m2 under the base case scenario, 5700 m 2 under the Save-E scenario, 5400 m 2 under the DR-W scenario, and 5600 m 2 under the DR-W+S scenario.
