However, despite these measures, on January 26 at 18:00, the Bishkek CHPP's load was reduced from 340 MW to 154 MW due to a temporary failure of the equipment for
makeup water supply for old boilers.
This means there will be relatively small amounts of
makeup water necessary to replace lost boiler water in the ethanol production process.
* Inspect and verify that
makeup water systems, pressure relief, air bleeds and vents, pot feeder, chemical treatment system, and expansion tank devices are installed and operating.
So, to get this to work, we needed to couple it up with a cooling tower, and the problem with cooling towers is that DEWA won't allow you to use potable water for the
makeup water. To get around this, we implemented grey water recycling and also collected condensate to use as the
makeup water.
To improve water reuse, Inalca installed a cooling water reuse system that incorporates vacuum pumps to collect the cooling water and reuse it as
makeup water for the evaporative condensers.
Qatar Cool has achieved the migration from potable water to TSE as the
makeup water source for the plants, the statement said.
"On a positive note, the developed DC markets are currently facing government regulation to achieve higher efficiency levels on both power and water front -reducing peak power consumption and higher operational power efficiencies by utilising thermal energy storage tanks & Treated Sewage Effluent for the
makeup water required."
The level of COC at which a specific system can effectively operate is very dependent on the composition of the
makeup water, particularly minerals and their quantity contained in the
makeup water supply.
The district cooling systems for Downtown Dubai will use wastewater as
makeup water for cooling towers to feed DCP1, DCP2 and DCP3 at Mohammed bin Rashid Boulevard, which will benefit the local environment by using an available resource rather than disposing of it, it said.
As cement fines accumulate in settling vessels, process water becomes less usable in fresh concrete mixes due to limits on the amount of solids that can be present in the
makeup water. The solids also present scaling problems in pumps, valves and other fittings in the piping systems that carry recycled water.
