Project execution in the industrial field is usually divided into six links: scheme design, hardware procurement, software programming, cabinet integration, site installation and equipment debugging. Many of the early OEMs and SIs were omnipotent. With the development of the industry and the maturity of the market, the division of labor in each link is becoming more and more fine. Many OEM and SI customers gradually outsource non-core business for the purpose of reducing costs and improving flexibility. The common way is to outsource the hardware integration of the cabinet to the disc factory, and then more and more links are outsourced. In the same period, many agents are trying to transform to the upstream and downstream of the business chain in order to avoid undifferentiated competition. Among them, it is a common way to make use of technological capability to do projects, but because we do not know the industry process, we often can only do some simple projects. There may be no relationship between the two projects, and the accumulation of technology can not be formed. In many cases, it is still a price war, which is far from the goal of integrators. In recent years, Beijing Zhongheng has explored various aspects of project business and sought breakthroughs.

In recent years, there are many water treatment projects. One of Zhongheng's partners, a key player in the main integrator in the industry, has also received many projects. The problem of insufficient technicians highlights that it takes time to train internally, to recruit skilled workers and integrate into the company. Moreover, when the industry cycle passes, too many technicians will cause high costs. The customer management decided to outsource programming and debugging of some projects and began to screen suppliers. Zhongheng's sales representative learned this information, feedback to the technical department, then Zhongheng decided to seize this opportunity.

The customer, strict in supplier selection, has requirements for company qualifications and technical personnel capabilities, and has its own programming standards and rules for field debugging. After all aspects are satisfied can Zhongheng enter the shortlist. Beijing Zhongheng's team has communicated at the end of 2018. After four rounds of communication with the customer's defferent departments such as Project, Engineering, and Procurement, the contract was finally signed in May, 2019. The contract includeed the programming and debugging of the concentrated brine treatment project in 3 sites at Huineng, Hongqing River and Inner Mongolia, in which Densadeg high density tank process is the core process of the customer.

Densadeg High Density Sedimentation Tank of Discharge System of Inner Mongolia Huineng Coal Chemical Co., Ltd. has been commissioned. Since the completion of acceptance of the project, the system control procedures and various equipment have been running steadily. The total amount of treated water can reach 310 cubic meters/hour. Meanwhile, zero discharge of sewage has been realized, which effectively protects the environment. The ecological environment of the land. In the near future, with the putting into operation of Hongqinghe and Yitai Chemical Projects, it will provide 20,000 cubic meters of industrial water for coal-chemical enterprises every day, which is of great significance for water-deficient cities in the North China.
