With the increasing demand for quality of life, whole-house water purification systems have become an important part of modern homes. This article will systematically explain the design specifications, equipment selection points, installation standards, and maintenance plans for whole-house water purification systems, providing comprehensive technical reference for industry practitioners.
System Composition and Scientific Configuration
The core of a whole-house water purification system lies in its multi-level water treatment plan. The pre-filter, as the first line of defense, should be selected with a filtration accuracy of 90-100 microns, equipped with a backwash function, to effectively intercept large particles such as rust and sediment from the pipeline. The central water purifier typically uses composite filter media of activated carbon and KDF, and the treatment capacity needs to be reasonably configured according to the number of family members, generally calculated based on a standard of 200 liters per person per day. The selection of the water softener should focus on the raw water hardness; each mg/L of hardness requires a corresponding resin exchange capacity of 1 gram/L. The point-of-use (POU) drinking water purifier is recommended to use reverse osmosis technology to ensure the effluent meets direct drinking standards. The configuration of the instant hot water dispenser should consider the usage scenario and select appropriate heating power and capacity. The linkage control of various equipment should be achieved through a central controller to ensure coordinated system operation.
Precise Calculation of Design Parameters
Scientific design calculations are the guarantee of stable system operation. The estimation of peak water consumption should comprehensively consider the number of family members, water usage habits, and special needs. Generally, the design flow rate for a family of four should not be less than 2.5 m³/h. The pipeline flow velocity should be controlled within the range of 1.0-1.5 m/s, ensuring both water usage experience and avoiding water hammer phenomenon. The system pressure loss should be controlled within a reasonable range; the pressure loss of a single device should not exceed 0.05 MPa, and the total pressure loss of the entire system should preferably be controlled within 0.15 MPa. The selection of equipment capacity should reserve 20%-30% margin to adapt to future changes in water demand. The installation space should be planned in advance to ensure sufficient operating space for equipment maintenance and filter media replacement. The assessment of drainage conditions should pay special attention to the diameter and slope of the drain pipe to ensure smooth sewage discharge.
Professional Standards for Equipment Selection
Equipment selection should follow strict technical standards. The matching of treatment flow should be based on actual water demand, avoiding situations of "using a big horse to pull a small cart" or insufficient capacity. The grading of filtration accuracy should be scientific and reasonable, forming a complete protection chain from coarse filtration to fine filtration. The selection of the water softener regeneration method should comprehensively consider water hardness and water usage; time-type is suitable for families with regular water usage, while meter-type is more suitable for situations with large fluctuations in water usage. The selection of the control valve should focus on its reliability and functional completeness, and it is recommended to choose products from well-known brands. The materials of all water-contact components must comply with food-grade standards to ensure water safety. The evaluation of energy efficiency should comprehensively consider water efficiency and power consumption, prioritizing products with Grade 1 energy efficiency.
Engineering Installation Technical Specifications
Standardized installation is the cornerstone of reliable system operation. Pipe connections should use professional pipe fittings and tools to ensure firm connections and no leakage. Copper pipes use welded connections, PPR pipes use hot melt connections, and stainless steel pipes use press-fit connections. Electrical wiring must strictly implement safety specifications, with grounding resistance not greater than 4Ω and leakage protection action time not exceeding 0.1s. Drainage pipes should be equipped with traps to prevent odor backflow, and the drain pipe diameter should not be less than DN50. The installation of load-bearing supports should ensure firmness and reliability, with support spacing not exceeding 1.5 meters, and important equipment should have separate supports. System debugging should be carried out step by step, including pipeline flushing, individual equipment debugging, and system linkage debugging. Labels and signs should be clear and complete, including content such as flow direction, equipment parameters, and precautions.
Systematic Operation and Maintenance Management
A complete operation and maintenance system is the guarantee for long-term stable operation of the system. Daily inspections should focus on pressure gauge readings, abnormal sounds, leakage conditions, etc., and records should be kept. The regular maintenance plan should detail the time nodes for various maintenance contents, including filter media replacement, membrane element cleaning, salt tank replenishment, etc. The filter media replacement cycle should be determined according to actual usage conditions; activated carbon is generally used for 6-12 months, RO membrane for 2-3 years, and softening resin for 5-8 years. The disinfection and cleaning procedures should be standardized, using food-grade disinfectants, and sufficient flushing should be performed after disinfection. A management system for consumables inventory should be established to ensure an adequate reserve of common consumables. Performance testing should be conducted regularly, including water quality testing and equipment performance evaluation, to identify and solve problems in a timely manner.
Strict Quality Acceptance Standards
Quality acceptance is an important link to ensure the system meets design requirements. Water quality testing should cover key indicators such as turbidity, color, total hardness, and total bacterial count, ensuring that all indicators meet design requirements. System operation testing should verify the functional integrity of each device, including automatic backwashing, regeneration program, fault alarm, and other functions. Document delivery must be complete, including design drawings, product manuals, certificates of conformity, warranty cards, etc. Operation training should cover daily use, simple fault handling, maintenance, and other content. After-sales service should specify response time and service standards, generally requiring a 24-hour response and resolution within 72 hours. The quality guarantee period should specify the warranty time for each component, with the core components warranty period not less than 3 years.
