5 key performance indicators in reverse osmosis operation
WEBDec 22, 2015 · The five most important parameters in reverse osmosis are the silt density index (SDI), differential pressure, normalized permeate flow, percent rejection and pressure drop coefficient. Reverse osmosis (RO) is a process that forces a feedwater stream containing dissolved impurities (salts and organics) through a semipermeable …
Best practices for collecting water samples
WEBOct 9, 2014 · A good way to determine if you have run the water enough is to use onsite measurements like pH, temperature and conductivity. Take measurements every two to three minutes, and once you get three consistent measurements in a row, you are ready to collect samples. Once you have allowed sufficient water to flow, you are ready to collect …
Understanding and preventing heat exchanger fouling
WEBNov 12, 2019 · The most common definition of fouling in relation to heat exchangers is the deposition and accumulation of unwanted material such as scale, suspended solids, insoluble salts and even algae on the internal surfaces of the heat exchanger. Depending on the materials involved, this fouling can occur on both the primary and service …
Boiler Feed Water Treatment for Industrial Boilers and Power Plants
WEBNov 1, 2004 · New Logic's VSEP system provides an alternative approach for boiler feed water treatment applications. In a single-step operation, VSEP will reduce hardness, TSS, TDS, and conductivity to provide a high quality boiler feed water stream for industrial boilers and power plants. In many applications, the addition of VSEP will eliminate ...

The basics of activated carbon adsorption | Water Technology
WEBFeb 1, 2016 · Activated carbon removes water soluble organics and solids from water by backwashing. This MTZ has three working zones: Zone 1 (between A and B, a portion of the total length of the carbon bed) is completely used and no longer removes water-soluble contaminants. Zone 2 (between B and C) removes variable amounts of contaminants.
New Guidance On Boiler Feedwater Sampling and Monitoring …
WEBNov 1, 2006 · 1. Standard, accepted good sampling practices require a minimum of 3 sample system volumes be purged before a sample is considered “representative” of the system. For example, ten feet of 1⁄4” tubing with a wall thickness of 0.035” would require 18 seconds to flush while 100’ of the same tubing would require 3 minutes to flush.2 ...
The benefits of harvesting HVAC condensation | Water Technology
WEBFeb 17, 2017 · With proper planning, HVAC condensation recovery can bring numerous benefits to building owners and managers including alignment with LEED and other green initiatives. Most of all, for businesses looking to rein in their fresh water use, harvesting and reusing condensate can keep good money, like good water, from going down the drain.
