Tongling Yurun International Plaza, an urban complex developed by the Yurun Group, is located in the main commercial district of Tongling. With a total investment of 13.8 hundred million yuan, the 186-meter tower has 45 floors, including 42 above ground and 3 underground. It is the tallest building in Tongling.

The Tongling Yurun International Plaza complex has a themed commercial area of 5 × ten thousand square meters. It provides employment for more than 5000 people, with annual sales of 20 × one hundred million yuan and profits and taxes of 1.6 × one hundred million yuan. The development will expand local retail, business, and service facilities and help the city attract commerce and investment.

However, as the number of catering companies increased, the original old model Integrated Grease Separation and Pumping System was gradually unable to meet the needs of normal use. In actual use, because the equipment was an old model, the oil and slag removal efficiency was not high. The grease residue generated by long-term use gradually accumulated in the equipment, blocking the pipes, further reducing the equipment's oil removal efficiency. At the same time, because the old equipment was open, the odor generated by the waste residue and grease accumulated in the equipment was directly discharged into the oil separation machine room, seriously polluting the environment of the entire underground parking lot where the machine room is located.

In view of this, recently, Hefei EPANEL Water Supply Technology Co., Ltd.’s oil isolation equipment has officially entered Tongling Yurun International Plaza.

PGI-300 series intelligent Integrated Grease Separation and Pumping System is the third generation product of Hefei EPANEL Water Supply Technology Co., Ltd. that has comprehensively upgraded oil separation equipment. Combining domestic and foreign advanced control technology, the product has made a number of technical improvements and upgrades and optimizations. It has the functions of automatically separating debris and automatically collecting it into a debris bucket, automatically separating sludge and collecting it into a sludge bucket, automatically separating grease and automatically collecting it into an oil collection bucket, and automatically lifting and discharging sewage to the municipal pipe network.

The equipment adopts a new multi-stage oil-water separation treatment process design, unique structural design and intelligent control system, which effectively solves the problems of debris separation, sludge separation and collection, oil-water separation and collection in basement catering wastewater treatment. It has significant advantages such as easy operation and maintenance, stable and efficient operation.
