Wastewater treatment facility
The wastewater treatment facility was assumed to be working on secondary treatment alone
since no grits and other unnecessary solids are present in the wastewater. SBR/ Sequential Batch
Reactor was used for this treatment. The sequencing batch reactor was developed in the early
1900’s but did not become popular until reliable and cost-effective mechanical equipment and
digital controls became available in the late 1970’s. The SBR is a fill-and-draw system. In this
system, wastewater is added to the reactor, treated to remove undesirable components, and then
discharged. For larger flows, two or more tanks can be used in an alternating sequence. SBR
systems consist of several treatment phases that make up a complete treatment cycle. Most systems
operate from between 3 and 6 cycles per day. Our Sabre package sequencing batch reactor (SBR)
plants are typically provided in buried fiberglass tanks designed to be out of sight and out of mind.
According to EarthTec, the Sabre SBR provides complete nitrification of the influent
ammonia during the aerated-fill and the react phases of treatment. During the beginning of a
treatment cycle, wastewater is fed into the SBR with only mixing and no aeration. This is an anoxic
mixed-fill phase and provides denitrification of the nitrified effluent from the previous batch.

Contingency Cost
For contingency cost, a rule of thumb of 0.1 of the sum of the ISBL and OSBL was
used which was base on Towler (2013).

Working Capital
The Working capital was calculated using the rule of thumbs on chapter 9 Towler
(2013) as a function of cash cost of production and raw material cost.
