Import 500lph Per Hour Ro System Water Filter System — Buy in wholesale FOB from Supplier in China

This 500LPH reverse osmosis water filter system produces 500 litres of purified water per hour through membrane-based separation, with core membrane elements sourced from an American brand. The unit employs automatic liquid-level and pressure control, with automatic opening and closing functions integrated into its operation sequence. A waterless protection system prevents dry-running damage to the high-pressure pump and membrane array. The system sits at a compact scale suited to small commercial premises, clinics, food-preparation sites, and light industrial operations where consistent purified water volume matters more than massive throughput.

The pre-treatment stage typically includes multimedia filtration and activated carbon adsorption to protect the RO membrane from particulate fouling and chlorine degradation, though buyers should confirm the exact pre-treatment train with the supplier. The American-branded membranes indicate thin-film composite polyamide construction, standard for commercial RO systems in this capacity range. Recovery rates for 500LPH systems of this class typically fall between 50% and 75%, depending on feed-water chemistry and operating pressure. Stainless steel or reinforced FRP housings are standard for the pressure vessels at this scale. Feed water TDS, temperature, and pH all influence actual output quality and membrane lifespan.

Buyers operating bottling lines, pharmaceutical compounding, or semiconductor rinsing applications find this capacity bracket matches their daily batch requirements without redundant oversizing. The automatic control architecture reduces operator attention to periodic sampling and filter replacement scheduling. Sourcing from Ningbo offers proximity to Zhejiang's machining and plastics industries, with potential for custom cabinet fabrication or interface language adjustment. Buyers should confirm whether the quoted 500LPH refers to permeate output at standard test conditions or at their local feed-water temperature, as colder source water reduces flux substantially.

Ningbo Golden Yangtze River Water Treatment Equipment Co., Ltd. operates from No 1111, Cidongnan Road, Ningbo, Zhejiang Province, 315201, China. The company holds a harbor trust tier on the platform, with a response rate of 0.00% and no recorded average response hours, meaning buyers should expect to initiate contact and allow time for reply. The supplier's listed product focuses on membrane-based water treatment equipment with automatic control features and American-branded membrane components.

The supplier profile does not state founding year, factory size, staff count, revenue figures, or specific client references, so any such claims would be invention. Buyers should verify manufacturing capabilities, quality management certification status (such as ISO 9001), and whether the company performs in-house membrane housing fabrication or sources complete skid units. The Ningbo location provides access to Zhejiang's established supplier base for pumps, pressure vessels, and electrical components common to water treatment assembly.
