Iron Oxide Removal Chemical

ChemWorld QK401 is a unique neutral pH cleaner. It is specifically designed to effectively dissolve iron oxide deposits from multi-metal closed water systems, while at the same time protect the base metal from corrosion. ChemWorld QK401 should be used only in closed systems that have no significant areas open to the atmosphere. This product is used in both boiler and cooling water applications.

• Removes iron deposits
• Non-hazardous solution can be discharged after use
• Can be used in-service
• Effective at elevated temperatures
• Compatible with multiple metallurgies

This product comes in a 5-gallon pail.

Feedrate

• 3 to 10% (40 to 80 lbs (3 to 10 gals) /100 gals system volume)

Control

• The solution turns a dark, turbid green color, indicating completion of cleaning.
• pH will be >6.0 (probably 6.5) when cleaning is complete.

For all new cooling tower startups, consider our ChemWorld 101 Cooling Startup Kit. This kit includes the following:

• One 5 gallon pail of ChemWorld Q-ALK-PC - This product is required to clean the debris and greases prior to startup.
• One 5 gallon pail of ChemWorld 1334 - ChemWorld 1334 is scale and corrosion control cooling tower chemical. After startup you can perform testing of your water hardness and alkalinity and we can tune in your exact chemical for long term protection.
• One 5 gallon pail of ChemWorld 56 - ChemWorld 56 is a 12.5% sodium hypochlorite product that is required to kill bacteria. This is the cheapest easiest product to get your system up and going, you can convert to tablets or a stablized bromide product after startup.
• One LakeWood 140 Cooling Tower Controller - You will need to set the controller to feed and bleed the cooling tower water to maximize cycles and to minimize chemical usage rates. An optional dual biocide water treatment can be implemented after startup. This is model 1239597 (which is board mounted unit that has the flow assembly on the left).
• One 1167435 Cooling Tower Blowdown Valve (1" NPT) - This will be required when the cooling tower calls to release cooling tower water.
• Two Stenner 45MHP10 Adjustable Head Pumps - One pump is required for the corrosion/ scale prevention chemical and for the biocide. Each pump is rated to 100 psi, which should be enough to feed the chemical into the system. The ideal spot to feed the chemical is into the return header of the cooling tower. These Stenner Pump kits come with chemical injection valves that will allow for quick injection of each chemical into the side stream water loop that is used to monitor the cooling tower conductivity.
• One complete CWTK-200 Cooling Water Treatment Test Kit. This kit is contains every test you will need to set up and fine tune your water treatment program.
• One Chemical Metal Test Station Cabinet - You need to keep your test kits and lo sheets in one clean location. This test kit is ideal for cooling towers. Items in photo of test kit not included.

We are looking for a closed-loop heating system cleaner to aid in removing iron sludge. Any recommendations? The system has iron, brass. No stainless steel. Yes, ChemWorld QK401K will work fine.

What is the proper disposal of the post cleaning solution from QK401, please? Please refer to section 13 of the Safety Data Sheet for the disposal information.
