Pipe system cleaning and in-line treatment of spent cleaning solution |
abstract |
A mobile cleaning unit (50) is connected to a fouled pipe (60) to be cleaned . A pump (65) circulates cleaning solution from a reservoir (70) through an injection valve (80) in the mobile cleaning unit (50). The solution is regulated by diverter valves (85a, 85b) to an upstream valve (90), through t he pipe (60), out a downstream valve (100), and through a return valve (110) to the reservoir (70). Treatment is monitored at either an upstream (115) or a downstream isolation valve (118). Spent solution is recirculated until it is environmentally safe for discharge out a drain valve (120). The process minimizes both the volume of treated spent solution and the treatment time.< /SDOAB> |
