    • 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 the 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.
    • 移动清洁单元(50)连接到待清洁的污水管(60)。 泵(65)将来自贮存器(70)的清洁溶液循环通过移动清洁单元(50)中的注射阀(80)。 解决方案由分流阀(85a,85b)通过管道(60)通过下游阀(100)和通过回流阀(110)被调节到上游阀(90)到储存器(70)。 在上游(115)或下游隔离阀(118)处监测处理。 废液可循环使用,直到排出阀(120)排出环境为止。 该方法最小化处理的废溶液的体积和处理时间。
