How do I reuse boiler blowdown water?
The boiler blowdown can be reused without treatment as a portion of the makeup to the closed cycle cooling system. While this reuse scheme has little impact on the water intake requirements, it does provide a use for a blowdown stream that normally would be discarded, or require treatment prior to discharge.
What is blowdown water treatment?
Boiler blowdown is the removal of water from a boiler. Blowdown is also used to remove suspended solids present in the system. These solids are caused by feedwater contamination, by internal chemical treatment precipitates, or by exceeding the solubility limits of otherwise soluble salts.
What is CTBD?
The make-up water Cooling tower blowdown water treatment presents several challenges due to the high salt concentrations and chemicals added in the cooling tower. This can result in many problems in the cooling tower such as corrosion, scaling, fouling and microbiological growth. …
Why is CW blowdown required?
Blowdown: When water evaporates from the tower, dissolved solids (such as calcium, magnesium, chloride, and silica) remain in the recirculating water. As more water evaporates, the concentration of dissolved solids increases. If the concentration gets too high, the solids can cause scale to form within the system.
What is composite boiler?
marine. A firetube boiler which can generate steam by oil firing or the use of diesel engine exhaust gas.
How does a blowdown system work?
Blowdown occurs when water is removed from a steam boiler while the boiler is operating. Boilers are “blown down” to remove suspended solids and bottom sludge from steam boilers. Removal of suspended solids helps insure the boiler generates high quality steam.
What is COC cooling tower?
COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower. PausePlay.
What is blowdown valve?
1. n. [Production] A valve or system of valves that, when activated, initiates a blowdown of a pipeline, plant, process, or platform; similar to an emergency shutdown valve (ESDV) that shuts in a pipeline, the BDV opens a pipeline.
What is COC chiller?
COC or the Cycles Of Concentration is an abbreviation, used when talking about cooling water or cooling tower water. The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower.
Can You reuse cooling tower blowdown water?
Cooling Tower Blowdown. In many facilities, the make-up water to their cooling tower can be 50% of the total demand for fresh water. With water scarcity in many areas, the reuse of cooling tower blowdown water was introduced.
How much of blowdown water can be reused?
Overall water efficiency increases and almost 100% of blow down water can be reused. Lenntech provides sustainable and complete solutions for blowdown water treatment and reuse considering a wide range of technologies and strategies.
What is cooling tower blowdown?
Cooling Tower Blowdown. What is cooling tower blowdown? The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating water systems in the thermoelectric power, refineries, petrochemical and other industries .
What are the benefits of blowdown water treatment?
Benefits of blowdown water treatment include: less maintenance, lower fouling and corrosion, reduction of chemicals used, more stable water quality. Overall water efficiency increases and almost 100% of blow down water can be reused.
