Acid cleaning / cleaning agent process and device after acid cleaning/cleaning ductwork

在清洗或酸洗管道系统后对酸洗/清洗剂进行处理的方法，其中，作为酸洗/清洗剂使用含水的3至5％的高CSB值的酸洗/清洗剂溶液，并且所述方法包括下列步骤：在酸洗或清洗过程后将酸洗/清洗剂溶液收集到一个容器或罐中；接着通过在一个反渗透设备中的过滤使酸洗/清洗剂溶液的CSB值降到小于100mg/l，其中反渗透设备至少单级地构成，并且在采用多级反渗透设备时将各级串联连接。 Following the installation of a boiler pipe system and prior to first flooding with water and start-up, the pipe syst...

Zusammenfassung:	在清洗或酸洗管道系统后对酸洗/清洗剂进行处理的方法，其中，作为酸洗/清洗剂使用含水的3至5％的高CSB值的酸洗/清洗剂溶液，并且所述方法包括下列步骤：在酸洗或清洗过程后将酸洗/清洗剂溶液收集到一个容器或罐中；接着通过在一个反渗透设备中的过滤使酸洗/清洗剂溶液的CSB值降到小于100mg/l，其中反渗透设备至少单级地构成，并且在采用多级反渗透设备时将各级串联连接。 Following the installation of a boiler pipe system and prior to first flooding with water and start-up, the pipe system is pre-cleaned by a liquid etching agent which is a 3-5 % solution of the agent in solvent with a high chemical oxygen demand (COD) value. Following the cleaning cycle, the dilute agent is drained to a tank and the COD is reduced to less than 100 mg/l in a single- or multi-stage series reverse osmosis filtration process. An independent claim is also included for: a commensurate assembly.
