Water purification equipment quality appraisal

water purification equipment is equipment that produces water purification. Purified water is widely used by us in: domestic drinking, chemical industry, medical treatment, breeding, planting, food, beverages, etc.
water purification equipment uses the internationally popular reverse osmosis method to filter source water (physical method) without adding any compounds to produce pure water for people to drink directly. It is a purely physical filtration method that does not require heating or chemical reactions. It is called "healthy water" in the 21st century.
Zhongke Testing and Appraisal Institute can provide water purification equipment quality appraisal services and make accurate appraisals in terms of product design analysis, load analysis and product quality analysis.

According to different usage requirements and designs, water purification equipment can be divided into two categories: gradual tightening type and self-cleaning type.
water purification equipment can also be divided into household-specific and enterprise-specific according to the purpose. Household water purifiers are usually smaller in size, while corporate water purifiers are larger in size.

GB/T 5750.4-2006 Standard inspection method for drinking water Sensory properties and physical indicators
HJ 1075-2019 Water quality Determination of turbidity Turbidimeter method

A technology company purchased 6 high-efficiency nanofiber integrated water purification equipment from a chemical company. During the commissioning, it was found that the water output was insufficient, the water was turbid, and it still could not operate normally after repeated repairs. Therefore, the technology company went to court.
Our company was entrusted by the court to undertake the quality analysis of the "water purification equipment" involved in this case.
identification and analysis results: The
quality analysis expert group discussed and comprehensively analyzed the relevant information, on-site investigation and inspection data, and inspection and testing data of the "water purification equipment" involved in the case, and made the following quality analysis conclusions. See:
The nameplate information of the "water purification equipment" involved in the case shows that the designed water output is 150T/H and the maximum output is 160T/H, which does not meet the requirements of "the integrated equipment design requirement reaches 180T/h" in the "Purchase Contract" provided by the client.
The thickness of the side panels of the "water purification equipment" involved in the case is 7.5mm, which does not meet the requirement of "the thickness of the side panels is 10mm" in the "Purchase Contract" provided by the client.
According to the turbidity test of the effluent samples of the "water purification equipment" involved in the case, the effluent turbidity of the high-efficiency nanofiber integrated water purification equipment involved in the case did not meet the requirement of "the effluent turbidity is less than or equal to 1NTU" in the "Purchase Contract" provided by the client.
