Secondly, to do sewage treatment equipment requires strong capital. Sewage treatment equipment than to do industrial ultrapure water equipment such as front-end water treatment equipment needs more money, because it needs to deal with all aspects of people.
Lastly, do sewage treatment equipment sales, to strong relationship, especially with the local environmental protection department. A project to do down, the relationship is not good, the local environmental protection department does not give acceptance, the project is done in vain.
