Yanjing Zoucheng Water Treatment Prefabricated Case

● Project Name: Yanjing Beer (Shandong) Co., Ltd. Water Treatment System Project

● Core Objective: Design, construct, and operate a highly reliable, automated water treatment system that transforms raw water (such as tap water and groundwater) into brewing water with precisely controllable chemical composition, thereby ensuring consistent, typical, and high-quality beer flavor.

● Project Planning: Design drawings and technical specifications involve pre-assembling, integrating, and testing multiple independent components—including water treatment equipment, pipelines, valves, instruments, electrical systems, and control systems—on a common base or modular framework. This results in fully functional, plug-and-play process modules that can be delivered to the project site as a whole for rapid installation and connection.

● Prefabrication concept for the project: Transform traditional “on-site construction” into “factory manufacturing,” and reframe the project site from a “construction site” into an “integrated assembly workshop.”

● Project Scope: Common prefabricated components include reverse osmosis (RO) units, multi-media filters, activated carbon filters, chemical dosing systems, pump sets, electrical control systems, and security filter units. All piping and equipment are made of sanitary-grade 316L stainless steel to ensure water quality and water safety.

Prefabricated reverse osmosis unit

I. Core Concepts and Objectives

Definition: The reverse osmosis unit is prefabricated by pre-assembling the core components of the reverse osmosis system—such as high-pressure pumps, membrane pressure vessels, piping, valves, instruments, control cabinets, and more—on one or more common bases or modular frames, in strict accordance with design drawings and hygienic standards. This results in a complete, tested, and functional unit that is then transported to the brewery site for rapid connection and commissioning.

Core objective:

● Quality assurance: Precision assembly and welding are performed by professional technicians in an ideal environment, ensuring quality that far exceeds on-site construction.

● Shorten construction period: Significantly reduce on-site installation, pipe welding, and wiring time, enabling “startup within one week.”

● Reduce risks: Minimize on-site construction errors, prevent cross-contamination, and ensure hygiene and safety.

● Easy to debug: Key performance tests have been completed before shipment, significantly shortening the on-site commissioning period.

II. Prefabrication of the Electrical and Automatic Control Components

● Control cabinet integration: Integrate electrical components such as PLCs, frequency converters, circuit breakers, contactors, and others into the control cabinet, and complete the wiring inside the cabinet.

● On-site cable laying: Lay cable trays on the base, pre-install cables for sensors and actuators, and leave sufficient length for field terminations.

● PLC Programming and HMI Configuration: Complete the programming of the core control logic and configure the touch-screen human-machine interface to enable fully automatic operation, flushing, chemical cleaning, and interlock protection functions.

Secondary Concentrated Water Reverse Osmosis Unit

I. Core Concepts and Definitions

Definition: The secondary concentrate reverse osmosis unit, also known as concentrate RO or secondary reverse osmosis, is a stand-alone reverse osmosis system specifically designed to treat and process the concentrated brine discharged from the primary RO system.

Core purpose: Further enhance the system’s overall recovery rate and achieve wastewater reduction. By re-desalinating the concentrate from the first-stage RO, the resulting secondary freshwater is recycled back to the front end of the system, thereby minimizing the volume of concentrated brine discharged at the end.

II. Design Purpose and Necessity

Core purpose:

● Increase overall system recovery rate: Boost the recovery rate of the first-stage RO system from approximately 75% to 90% or even higher.

● Wastewater reduction: Significantly reduce the volume of concentrated wastewater that ultimately needs to be discharged or further treated, thereby lowering the pollutant discharge load and associated costs.

● Resource recovery: The recovered secondary permeate is routed to the primary RO permeate tank or the system’s front end, thereby increasing the total water production.

Prefabrication Description of High-Pressure Pump Unit

One, Core Concepts and Definitions

Definition: Prefabrication of high-pressure pump units: All components—including high-pressure pumps, motors, frequency converters, piping systems, valves, instruments, bases, and control systems—are pre-assembled, integrated, and tested according to precise design drawings and specifications into a complete, unified power module. This module is then transported as a whole to the project site for rapid installation and connection.

● Core value: Transform a “component assembly” that requires complex on-site installation into a “plug-and-play” functional product.

● Application scenario: Primarily used in reverse osmosis systems;

II. Prefabrication Objectives and Advantages

● Ensuring ultimate quality: Precise alignment—on a stable foundation, with professional technicians and laser alignment instruments, the pump and motor are precisely aligned, delivering far superior quality compared to on-site conditions and significantly reducing vibration and wear.

Cleanliness Control: A clean factory environment ensures that the interior of pipe welds remains free of oxidation and welding slag, thereby preventing impurities from entering the pump body or downstream RO membranes.

● To shorten construction periods: Factory prefabrication can be carried out in parallel with on-site civil engineering and pipeline installation. On-site, only simple lifting, positioning, and pipeline connection are required, reducing on-site installation and commissioning time by more than 60%.

Minimize risk to the greatest extent:

● Safety risks: Reduce on-site hot work,高空作业, and heavy-lifting operations.

● Performance Risk: Comprehensive testing has been completed prior to shipment, effectively eliminating equipment damage caused by on-site installation errors (such as improper alignment or excessive pipeline stress).

Prefabricated Pump Unit Project Description

I. Core Concepts and Definitions

Definition: Prefabrication of Pump Units: Based on design drawings and specifications, all components—including pumps, motors, valves, pipelines, filters, instruments, control systems, and structural foundations—are pre-assembled, integrated, and tested into a fully functional, compact, modular unit. This unit is then transported as a whole to the project site for rapid installation and connection. · Core Concept: Transform complex, multi-disciplinary on-site construction into standardized, assembly-line-style production, assembly, and testing conducted in a factory setting.

II. Objectives and Driving Forces of the Prefabrication Model

Outstanding quality:

● Precision Alignment: On a stable foundation, professional technicians using laser alignment instruments perform precise alignment of the pump and motor—achieving accuracy far superior to on-site conditions and fundamentally reducing vibration and wear.

● Clean Environment: The factory environment is protected from wind, sand, and rain, ensuring that the inside of pipe welds remain free of oxidation and welding slag, thereby guaranteeing system cleanliness.

● Dramatically shortened construction period: Factory prefabrication can run concurrently with on-site civil engineering and pipeline installation, simplifying on-site work to “lifting and hoisting plus connection,” thereby reducing on-site installation and commissioning time by more than 60%.

Substantially reduced risk:

● Safety risks: Reduce on-site hot work,高空作业, and heavy-lifting operations.

● Performance Risk: Before leaving the factory, comprehensive testing is conducted to eliminate equipment damage and substandard performance caused by on-site installation errors (such as improper alignment or excessive pipeline stress).
