Jan 19, 2004· Black, magnetic debris in boiler feedwater loop (e.g. feedwater, boiler water, steam condensate) could be due to too much reducing agent (i.e.oxygen scavenger) as well as low pH. If oxygen is in excess I would expect to see some red-orange debris. Howver, oxygen can not be ruled out as a part of the cause of the black debris.Get a Quote
Pulp mill - Wikiped
A pulp mill is a manufacturing facility that converts wood chips or other plant fiber source into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods (kraft and sulfite processes). The finished product may be either bleached or non-bleached, depending on the customer requirements.Get a Quote
